Record Heat Waves Plague the Planet

There will be more severe heat waves. They will become hotter, more frequent, last longer and occur in more varied places.

By Dr. John J. Hidore
February 12, 2019——Heat wave is a general term. When it seems unusually warm someplace there is often a tendency to describe the weather as a heat wave. As it turns out it is very hard to define a heat wave. The reason is simple. Normal summer high temperatures vary greatly from place to place. What would be defined as a heat wave in one location would not be appropriate for another location, perhaps not even too far away. An adequate definition might be, “A heat wave is an unusually warm or hot period lasting for days or perhaps weeks.” We associate them with summer but by this definition they can actually occur at any season.

climate change

The exchange of energy is causing rapid arctic melting.

At least one country makes a clear definition of a heat wave and that is Pakistan. India also defines heat waves and uses different temperatures in different parts of the country to establish what constitutes a heat wave. In the plains regions of the Unites States, temperatures above 40degreesC (104 degreesF) constitute a heat wave. They also define a severe heat wave for this region as experiencing temperatures over 46 degreesC (114.8 degreesF).

Distribution of the 2018 Heat Waves

In 2018 the northern hemisphere experienced major heat waves. Heat waves occurred over most of the northern hemisphere as well as Australia. Europe experienced a major heat wave in the spring and summer. These extreme heat waves were largely a function of climate change, particularly of global warming.

Indian drought

Millions effected by the drought

Global warming also increases the probability of higher extreme temperatures during a heat wave. Such was the case in 2018. All-time highs were recorded in North America and Europe. At one location in Finland that is north of the Arctic circle, a temperature of 33.3°C (92°F) was recorded. Undoubtedly extreme highs were recorded in many other areas as well. Qurayyat, in Oman, experienced a 24 hour period when the temperature did not drop below 42.6°C. This was the highest minimum daily temperature ever recorded.

The Impact of the Heat Waves

The impacts of the heat waves were many and varied. They included:
A. Increased mortality: Japan, Algeria, and Canada recorded fatalities attributed to the heat.
B. Droughts and agricultural losses. In parts of Europe precipitation amounts fell to as little as 20% of normal.
C. The closing of nuclear power plants due to a shortage of water for cooling.
D. Frequent and severe wild fires. Severe wild fires occurred on every continent except Antarctica.
E. In 2016 and 2017 there was major bleaching of the Great Barrier Reef. In all probability 2018 will turn out to be the same
F. In the summer at one point the combined concentration of greenhouse gasses reached 500 ppm, approximately 100 ppm above the average for this time.

The Deadly Heat Wave of Europe in 2003

Some heat waves have become deadly. Perhaps the most deadly heat wave of the 21st Century was that which occurred in Europe in August of 2003. Temperatures in France reached as much as 40°C (104 DegreesF) and remained exceptionally high for two weeks resulting in nearly 15,000 deaths in that country alone. The death toll over Europe reached approximately 35,000 and may have been as high as 50,000.

Climate Change

The earth’s overall temperatures are increasing every year.

A large contributing factor in the high death toll was warmer than normal nighttime temperatures. As a result people without air conditioning could not cool down during the night. The heat stress accumulated over time. Extreme heat waves also can devastate agriculture. In Europe, in the heat wave of 2003, temperatures averaged 5.5°C (10°F) above normal. In Italy corn yields dropped 36% below average. In France fruit yields fell 25% and wine production 10%. Heat also affects the rate of plant pollination.

Asian heat waves of 2015

That year a May heat wave in India claimed at least 2,500 lives. Heat waves are fairly frequent in India but this was the greatest loss of life from a heat wave in over 30 years. Extremely high temperatures were reached in cities scattered over the country. Power outages were wide spread as a result of high demand for air conditioning. The city of Khammam recorded the highest temperature ever recorded there at 48 degrees C (118.4 degreesF). Other high temperatures that were recorded were:

Allahabad 47.8 degrees C (118.0 degrees F)
Delhi 45.5 degrees C (113.9 degrees F)
Hyderabad 46 degrees C (115 degrees F)
Jharsuguda 45.4 degrees C (113.7 degrees F)

In June the deadliest heat wave known to have occurred in Pakistan took place in the southern part of the country near Karachi. The death toll is unknown for certain but may have reached more than 1000. The heat wave struck during the month of Ramadan which made the impact of the event more severe than it might have been. Unfortunately, city services were not in condition to cope with the heat.

As the planet warms it can be expected that: (1) there will be more severe heat waves. They will become hotter, more frequent, last longer and occur in more varied places. As cities grow larger in area and population they will experience increasing heat waves. (2) new record high temperatures will be set more frequently on the planet.

The Colorado River: The Redistribution of Water

The Colorado River

The Colorado River is over allocated.

The Colorado River: “It is incumbent for us to safeguard, protect what we have left.”

By Linn Smith
February 6, 2019—The Colorado River has been over allotted from the beginning, as the Law of the River, a compact made in 1922 between the 7 Colorado River Basin states for the river usage, was made during a time of high precipitation. Today the population of states along the river has increased and the river has decreased due to over use and climate change.

Since the development of the compact, California has been using the surplus water that other states haven’t used in the lower basin states that include Arizona and Nevada.

With population growth both Arizona and Nevada are claiming their water allotments and the Upper Basin states have accused CAP, Central Arizona Project, of manipulating its share of water to keep Lake Mead low enough that the upper basin is required to send extra water, but high enough to avoid mandatory cutbacks in lower basin consumption.

#theoceancleanup

Big Solutions for the ocean cleanup

Colorado River: Lower Basin States

The lower basin states and Mexico depend, at least partially, on the water they get from Lake Mead and if the situation called “dead pool” develops, the level of the lake’s surface would fall below the gates of the dam that release the water. In this situation the lower basin states and Mexico would not receive water. To avoid this situation cutbacks are required. In the book “Dead Pool” by James Lawrence Powell, Powell states, “At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water-but there is no surplus water: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still.” This book was written in 2011. Today Lake Mead stands at 1079 ft, four ft away from the mandatory federal shortage declaration that would mandate cutbacks.

In an attempt to resolve the issue the Federal Government put a deadline on lower basin states to resolve the issues over water rights. The past several weeks have shown an attempt towards resolution. The U.S. Bureau of Reclamation expects an agreement on the drought plan by the end of January, 2019.

Colorado River

Depletion of water for crop irrigation

The Arizona Drought Plan

The drought plan requires Arizona to find a way to reduce its use of Colorado River water by up to 700,000 acre-feet — more than twice Nevada’s yearly allocation under the drought plan. An acre-foot is the volume of water needed to cover one acre of surface to a depth of one foot.

Arizona, the only state that required legislation to take less water from the river, was forced this month to either pass legislation by the end of January 2019 or let the federal government impose water restrictions, which could have meant less water than if state imposed. In Arizona the recent legislation resulted in negotiations between major water users, who agreed to reduce their water usage in exchange for cash or access to groundwater in the future.

Farmers in Pinal County, Az, who have the lowest priority to water rights, will receive restitution which includes $9 million to drill wells and build infrastructure to change from dependency on river water to groundwater. The farmers, who reluctantly supported the agreement, said it would require them to fallow as much as 40 percent of the county’s farmland.

“We inherited as human beings a pristine land with pristine water, and we messed it up as human beings ourselves,” said Sen. Jamescita Peshlakai, a Democrat who represents the Navajo reservation in northeastern Arizona and voted to join the drought plan. “It is incumbent for us to safeguard, protect what we have left.”

Climate Change has been at the Root of Major Famines

Drought in India

Indian drought causes famine.

“The demand and supply of food has been in a delicate balance for the human species throughout history.”

By Dr. John J. Hidore

October 30, 2018—–The term famine produces an image of starvation and suffering in the minds of most people. In general a famine is a lack of food sufficient to produce malnutrition in large numbers of people over a wide area. The United Nations considers several conditions for a regional food shortage to be considered a famine. They are:

1. At least 20% of families in the area face extreme food shortages that they cannot cope with.
2. Acute malnutrition in children exceeds 20%.
3. The death rate exceeds two persons for each 10,000 people per day.

The Role of Climate Change in Historic Famines

There are many causes of famine, including climate changes, war, and political policies. One of the major ones is drought. Most of the catastrophic famines in historic times have been precipitated by drought. Drought can affect the quality and quantity of crop yields and the food supply for domestic animals. In the case of severe drought there may be a substantial loss of domestic animals due to lack of food. The loss of milk products or meat itself can precipitate the effects of the drought.

The demand and supply of food has been in a delicate balance for the human species throughout history. When the food supply has increased there has been a gain in population, and when food has been in short supply there has been some sort of trauma inflicted on the populace. Starvation results from insufficient food intake. During the long period of the hunting and gathering societies, starvation was probably often near at hand for individuals, family groups and tribes.

Millions effected by the drought

Agriculture and Famine

The development of agriculture allowed the world population to expand rapidly and greatly. At the same time, the basis for the supply of food, namely agriculture, became more directly dependent upon the weather. Famine as a phenomenon did not become a part of human experience until after agriculture began. However, as agriculture expanded so did the frequency of famines. The number of times that famine has spread on the continents is enormous. Nearly all histories of peoples and nations record famines.

Great famines have occurred throughout the Asian continent. India, China, Russia and the countries of the Middle East have all suffered from famine, many times which were drought related. An example is the famine described as occurring during the time of Abraham (about 2247 B.C). Another massive famine occurred in Egypt prior to the exodus of the Israelites. Drought and famine are endemic in India and China. The oldest record of famine in India goes back to 400 B.C. and in China to 108 B.C. Since the time of the earliest known famine there have been nearly continuous episodes of drought and famine in many parts of Asia or Africa.

Indian drought

Global warming raises temperatures around the world.

The Impact of Drought in Developing Countries

Drought has a much greater impact on people in developing countries than it does in industrial societies. The primary reason for this is that in the developing countries there is more dependence on agriculture as a way of life. When crops fail, or there isn’t enough forage for livestock, there is an immediate effect on the populace.

A very positive aspect of famine is that they are becoming fewer and less extensive due to the ability of the global economy to move large quantities of food from place to place.

The USA National Phenology Network: Taking the Pulse of our Planet

Phenology

Climate change affects all life.

“Phenology is nature’s calendar. It’s the study of plant and animal life cycle events.”

By Linn Smith
June 14, 2018—–I learned about Phenology when visiting Biosphere 2 several months ago. Upon entering I asked the question, “But where is Biosphere 1?” “It’s our Planet Earth!” our guide answered. (I knew little before entering!) On the grounds of Biosphere 2 is the Biosphere Village Phenology garden.

Climate Change

Birds depend on insects to feed their young.

What is Phenology?

Phenology is nature’s calendar. It’s the study of plant and animal life cycle events, such as leafing and flowering of plants, emergence of insects, and bird migration. Many of these events are sensitive to climate change. Birds build their nest to coincide with insects coming to life after a long winter. The insects are the necessary food for the baby birds and, as the climate warms and winters shorten, this nesting time period will change.

Phenology

What is it?

Monitoring animal and plant life, or Phenology, can help scientists predict which populations are in danger of extinction. It can also help manage invasive species, help predict human health problems, such as allergies, and predict optimum times to plant and harvest crops.

The Biosphere Phenology Garden

“The garden at the Biosphere is part of a nationwide effort to help scientists track impacts of climatic variation and change on the natural world. We are monitoring the timing and occurrence of seasonal events of this garden and reporting the observations to USA-NPN’s national data base.” (USA National Phenology Network)

Phenology

It helps us understand our changing environment.

How You Can Help!

And this is how you can get involved! Citizen Scientists were developed so all can participate in monitoring nature and recording the data. The USA National Phenology Network brings together citizens, government agencies, educators, students and nonprofit organizations to monitor the impacts of climatic variation and change on plants and animals across the U.S. The network harnesses the power of people and the Internet to share information and provide data to researchers.

USA-NPN invites anyone interested to volunteer as an observer so that they can better understand environmental trends and adaptation to climate change. Your own yard can serve as a phenology garden where you observe plants and report your findings. You can track the phenology of plants and animals through Nature’s Notebook, which is an online monitoring system, contributing to a national database that can be used by scientists and resource managers.

Phenology

It can help us understand why nature is changing.

Citizen Scientists at Work

“Cathie Bird finds being outdoors healing and inspiring. She goes outside nearly every day to see what other species are up to, and after she heard about Nature’s Notebook, she decided to record what she observes for the benefit of science. She feels “being an observer has connected me even more deeply with life in my neighborhood” and has “enriched my lifelong commitment to cultivate a deeper relationship with Earth.

Chris Nielsen started using Nature’s Notebook to observe native plants in the Northwest several years ago. Chris not only monitors plants at his home, but also at the Kruckeberg Botanic Garden in Shoreline, WA. What does Chris recommend for getting started with Nature’s Notebook? Don’t take on too many plants! Start out with just a few then take on more as you get comfortable with the program.”

Now is the time to step up to the plate and help out…..the time was actually yesterday, but as the old saying goes, better late than never! Find out more information at: https://www.usanpn.org/natures_notebook

The Effect of Climate Change on the Saguaros of the Sonoran Desert

saguaro pic by Linn Smith

Saguaro of the Sonoran Desert

“Saguaros have evolved to rely on the summer monsoons and winter rains that prevail here.”

By Linn Smith
March 4, 2018—-Each morning I ride along the dirt paths in southwest Arizona, my dog in tow, and wonder at the giant Saguaros, towering, as if royalty of the desert. What do I know about these gigantic, human like plants? I know I am truly humbled by their presence. The beauty against the mountains, the size, the human like features of arms lifting to a blue sky above, their age and, while the world moves forward, these mammoth cactuses have survived the elements of a dry arid life in the Southwest…all part of my fascination!

But what about the survival of the Saguaros? What is the future of these majestic desert plants? With climate change comes a hotter, drier desert and with a hotter, drier desert comes a greater risk of fires and drought, making it difficult for the Saguaro to propagate according to the narrow margin of time allotted for seed dispersion that coincides with the monsoons.

And also….there’s Buffelgrass!

Saguaros

Buffelgrass competes with Saguaros for nutrients

Buffelgrass: A Giant Threat to a Giant Cactus

Buffelgrass is native to Africa and was transported to the desert of Arizona to prevent erosion and for cattle forage in the 1940’s. Many volunteers work tirelessly digging up the invasive grass, which competes with the Saguaros for food and water. The grass not only competes for the nutrients and water among the Saguaros, it is also fire-resistant, as the roots are able to survive a fire, allowing the Buffelgrass to endure the elements of nature and return healthier than ever.

Buffelgrass is highly flammable and burns very hot, much hotter than the Saguaros can survive. It changes a fire-resistant desert into a flammable grassland and, as climate changes and fires increase, so does the Buffelgrass. A healthy ecosystem is able to resist changes of climate due to global warming, but the buffelgrass creates an unhealthy environment for the Saguaros of the Sonoran Desert. When it fills in the bare areas between the Saguaros, the grass acts like fodder for fire caused by lightning strikes.

Climatecental.org states, “Like many such imports, which seemed like a good idea at the time, this one (Buffelgrass) has gone out of control. Approximately 2,000 acres of Saguaro National Park are currently covered with buffelgrass, and can spread at a rate of up to 35 percent per year. There’s no way for one park or its visitors to hold back global warming, but while park employees attack the fire-loving buffelgrass with herbicides, volunteers show up for communal buffelgrass pulls. It’s a difficult battle, but after great effort and thousands upon thousands of buffelgrass clumps yanked from the ground, mostly by volunteers, some land is declared free of the unwanted grass.”
The staff at Saguaro National Park states it like this, “The math of climate change is simple: Hotter summers mean a greater likelihood of fire. Warmer winters mean less chance for buffelgrass to die back in a hard freeze. It all adds up to long odds for the saguaros. If we start seeing buffelgrass come through and we have larger fires, really you can start calling us Buffelgrass National Park. The cacti are not going to survive that.”

Saguaro

Saguaros of the Southwest

The Saguaros and Monsoon Rains

The Saguaros only habitat on earth are the deserts of the southwest. Andy L. Fisher, chief of interpretation for Saguaro National Park says, “Even — or especially — in the desert, water is life. Saguaros have evolved to rely on the summer monsoons and winter rains that prevail here. Their adaptations to this regional weather cycle are so specific that the species is found in the Sonoran Desert and nowhere else on Earth. The saguaros have got it dialed in. They know exactly when they need to put up the fruit to put out the seeds, to get the seeds carried by the animals, to get seeds deposited just in time for the first monsoon rains.” If the monsoons fail to bring the needed rains within their usual timespan, these cactuses could soon become extinct, along with the many other species of plants throughout our planet dependent on timely conditions for survival.

Saguaro Population Regeneration

A seventy-five year study of the Saguaro cactus by the National Parks Conservation Association titled, “Saguaro Mortality and Population Regeneration in the Cactus Forest of Saguaro National Park: Seventy-Five Years and Counting,” created maps showing the percent of population change of the Saguaros according to sections. The study shows that only 12 of the 64 four-hectare (one hectare equals approximately 2.5 acres} plots had a population increase over the past 75 years in which the Saguaro was studied. The other 52 plots decreased in Saguaro population. Other studies document the same degree of regeneration.

Weiss, Castro, and Overpeck , who headed the study, contrasted the drought of the 2000s with the drought of the 1950s and point out the following. “Temperatures during the drought of the 2000s have been generally higher than during the 1950s drought due to climate change. They note that the higher temperatures increase the evapotranspiration especially in the foresummer prior to the monsoons. Hence, we suspect drought, not reproductive potential, is primarily responsible for the lack of regeneration in this population in the current era.”

The observations made during the past 75 years of this study suggest that the success of the Saguaro’s regeneration in the 21st century will depend on a combination of factors including climate and fire associated with the invasive non-native buffelgrass. Climate change may benefit some species, such as Buffelgrass, and cause extinction of others….the Saguaro, which is at risk of disappearing in the future!

If you are in the Southwest or just visiting and would like to spend a day for a worthy cause….digging Buffelgrass, contact the Desert Museum: https://www.desertmuseum.org/buffelgrass/volunteer.php

One last note, don’t try to poach a Saguaro to sell or relocate to your yard, as many are microchipped!

Why Coastal Cities Must Build Sustainably

Soft shoreline vs. Hardshoreline

Soft shorelines create spaces for the water to go.

Obama Presidential Adviser, John Holdren, said of the challenge of climate change, “We will end up with a mix of prevention, adaptation and suffering. It is for us to determine the ratio.”

By Linn Smith

September 18, 2017 ——With the recent flooding in Texas and Florida, it is evident that the rising seas from climate change will affect us by chronic flooding, which will become more frequent. There will be continued flooding and devastation from weather as our climate and seas warm up.
The Union of Concerned Scientists ask the question, “If flooding continues, how many times does it have to happen before you stop thinking of rebuilding and start thinking of relocation? Each community has a threshold for sea level rise and chronic flooding beyond which sustaining normal routines becomes impossible.”

climate change

Mitigation Vs. Prevention

Mitigation or Prevention

Scientist have worried for years that melting sea ice and ocean warming would cause a rise in sea levels, extreme weather and more severe and frequent hurricanes. What is our government’s responsibility? Do we continue to spend our tax dollars on mitigation, cleaning up the aftermath of the increasingly destructive power of storms? Do we continue to rebuild coastal areas that are vulnerable to climate change or do we have a responsibility to reconstruct cities and coastal areas against the coming vulnerability of our changing climate?

William V. Sweet, Scientist with the National Oceanic and Atmospheric Administration stated, “Once impacts become noticeable, heavy rains and extensive flooding are going to be upon us quickly. It’s not 100 years off anymore.” Higher seas mean higher storm surges. As seas rise in an area, the coastal creeks and marshes will rise and bring salt water inland. Many coastal trees will be affected by the saltwater rise.

Storm Surges

Protection from Storm Surges

Reducing the Impact of Rising Seas

What are our choices? Keep spending tax dollars on rebuilding coastal properties or rebuild naturally to reduce the impact of rising seas. A soft shoreline maintains the natural dynamics of the shoreline, with a healthy movement of the sand and improving habitats of sea life. It allows the coastline to do what it does naturally, without the build-up of asphalt and man-made dwellings. A living coastline has natural barriers, vegetation and salt marshes that make it a stronger buffer, against flooding, but also moves and changes as any undeveloped shoreline would.

Obama Presidential Adviser, John Holdren, said of the challenge of climate change, “We will end up with a mix of prevention, adaptation and suffering. It is for us to determine the ration.” There are consequences of inaction!

Hard Structures vs. Soft Defenses Against Wave Energy

What we’ve done with much of our coastal lines to deter flooding is to construct impervious surfaces and blockages to dissipate the wave energy. But there are natural designs that absorb water from storms and channel it back into nature, creating spaces that navagate the water naturally.
The current method of deterring sea wave energy are hard structures. Hard structures, such as sea walls, deflect the wave energy to adjacent areas, redirecting the wave to a neighboring property. These properties witness a greater destructive energy than the original destination of the wave. Walls can fail and waves can erode sand at the base of the seawalls. Walls can also be destructive to the surrounding flora and fauna, which may be preventing a more serious flooding disaster. Hard structures won’t save our cities from rising seas!

The better approach according to Rachel Gittman, Ecologist, is to create living shorelines. A living shoreline is site specific according to the natural habitat of the location. She states that for calmer waters, build water absorbing marshes with sill-like ledges made of rocks, oyster shells or coconut fiber logs. A shoreline may also benefit from planting mangroves, which firmly anchor the shoreline in place.

Rising Seas

Cities affected by the rising waters.

Natural Barriers of Wave Energy

Steven Scyphers, Coastal Scientist, states, “It starts with a good understanding of what the natural conditions along the shoreline once were. It could mean restoring what existed on the shore, whether oyster reefs, coral reefs or other living breakers that can dissipate the wave energy. These natural barriers become more suitable over time as the plants, roots and reefs grow.”

By 2100, 490 communities could be chronically flooded including Boston, L.A. and most of NYC. Communities will have to decide what will be best for them, flood walls, living shorelines, elevating structures or to retreat. Cities that are below sea level probably won’t be benefited from natural shorelines.

In the meantime we need to change our behaviors to slow down climate change!

Make a Difference: Action Against Climate Change

Global warming and climate change are real! Get involved.

You can help!

The truth is that individuals can and do make a difference.

By Dr. John J. Hidore

September 6, 2015—-I have been writing and talking about the massive and unexpected results of global warming and climate change for decades. The reaction I receive from some people varies from laughter to absolute denial of the existence of global warming and climate change. There will always be deniers! More often when I talk with people about climate change, they tell me they believe it is taking place, but as an individual, there is nothing they can do about it. I understand because I often feel the same way. My response is to suggest that, not only can they do something about it, but only when enough individuals demand action will those in power respond!

Education Against Destructive Policies

The truth is that individuals can and do make a difference. If you can get a number of individuals to work together, you have a group. In today’s world individuals can identify and join others in ways not possible a decade ago. The internet and social media allow individuals to find people with similar interests to work together, even if they are separated by long distances. If you can educate just one other person of the reality and consequences of following a destructive policy, such as denying global warming, you have made a difference! If you convince even a few people to change their position you have created a group to support your position. A group can make a difference! In communities a group can make a difference on policies and if a number of groups with the same goals come together you have a crowd. A crowd can make a difference in a city, county or state. When crowds in different locations combine their efforts, it is possible to change national policy. In this manner individuals can turn into a crowd in an unbelievably short time and make a big difference on political and economic decisions.

Here’s an analogy: If enough molecules of water combine they can form a drop of water. If enough drops of water come together, you can get a cloud or a lake. The ocean covers the majority of our Earth’s surface. Even the global ocean is formed from individual drops of water! Similarly, sand dunes are made up of individual grains of sand.

Sustainable living on a sustainable planet!

Let’s hand our children a healthy planet!

Defending Your View: Making a Difference

There are situations, time after time, when individuals have taken steps that have grown enough to force change. Everyone belongs to what I call a tribe. The tribe may be a religion, a country, a political party or some other group defined by a common interest. There are non-governmental organizations (NGOs) in many areas of interest. For instance, there are such groups on climate change, civil rights, theater and animal rights. Making a difference simply means taking action. Taking action means defending your view in your tribe. This is often difficult because, as an individual, you may not want to risk your inclusion in the tribe. This is especially true if the bonds within the group are family or workplace.

Earth Day, The Kyoto Conference and One Million Women

There are many examples of individuals starting an NGO, non-governmental organization, that are currently making a difference. To bring the focus to climate change, we have the creation of Earth Day in 1970 and the work of Senator Al Gore, who helped save the Kyoto Conference from ruin and formed the organization on climate change that became national and, subsequently, international, the Climate Reality Project. Another good example is “One Million Women” (see posting dated July 13, 2015). This group was started by two women after a discussion over coffee. They based their organization on the recognition that the choices women make could add up to a big difference in reducing waste and pollution. Their goal is to grow the group to one million members. By September of 2015 they have enlisted over 218,000 women to work together!

It becomes more important every day that global climate change needs to be addressed now! The evidence of the changing climate is overwhelming. Every year produces more evidence of the changing global system and the increasing stress to the human population and all other living things. It is essential that each of us become a part of the growing sea of the people demanding action to keep climate change and its consequences at a minimum, so future generations can inherit a healthy planet. We can do it!

Climate Change and the Global Food Supply

Some species may become extinct

The growing ranges of our food supply will change as the temperatures rise.

“When climate change is added to population growth, only the extent of future food shortage is unknown.”

By Dr.John J. Hidore

August 3, 2014—In the early 21st Century global food production is able to meet the global demand. However, the availability of food varies greatly from place to place. Approximately 870 million people living on Earth today are facing food shortages. These shortages result in nearly 15% of the population being malnourished to some extent, with many facing health problems. In Africa, a third or more children under the age of five undergo growth stunting due to malnutrition. The most extreme health problem is, of course, starvation. It is clear that food production is not keeping up with demand regionally, if not globally.

The Impact of Temperature Changes

Changes in climate are now having a major impact on food production, and certainly will have in the future. The biggest factor in climate change is the rapid rise in global temperatures. For instance, the mean temperature for May and June of 2014 were globally the highest on record. Nearly every forecast of global temperature increases, issued in recent decades, has been an underestimate of what has actually occurred. Since the 2007, IPCC (Intergovernmental Panel on Climate Change) report, the new estimate has placed the range of temperature increase as much as 14 degrees F (8°C) by 2100. This increase in temperature will greatly affect life on our planet, including agricultural production.

A food shortage is presently effecting a large portion of the earth's present population.

This may be a rare picture at the supermarket in years to come.

The Decline of Crop Yields

Because most plants evolved during cooler conditions associated with the ice ages, many plants are now growing near the upper limit of their range. Crop yields start to decline when temperatures reach or exceed the optimal temperature range. This is the case in the tropics as well as mid-latitudes. If the temperatures continue to increase, the result will be major changes in the regional growth ranges causing some species to decline in numbers.

Presently, the warmer conditions are now reducing some grass lands to desert conditions, due to greater evaporation and transpiration. It is possible that in the 21st century warming will be sufficient to make many plants extinct. Changes in the plant species growing ranges may become great enough to make some ecosystems non-functional.

Extreme heat waves can devastate crops. In the year 2003 summer temperatures in Europe averaged more than 10°F above normal. In Italy, corn yields dropped 36% below average. In France, yields of fruit fell 25% and wine production fell 10%. Heat also affects the rate of plant pollination. A 3 degree Fahrenheit raise in temperature, in rice producing areas, would cut rice pollination in half. Rising temperatures also increase the frequency and extent of plant diseases and pests.

Water Related Stress of Agriculture

Rising temperatures will, also, result in greater water related stress in agriculture. Agriculture is now the largest user of water on a global basis. Crop production uses some 70 percent of fresh water on a global basis, and about 80 percent in the developing countries. Evaporation rates will increase and, inevitably, less of the global fresh water will be available for irrigation. Over a third of the global human population now lives in water stressed regions. The ratio of population living with water related stress may increase to 50% by 2100.

The transformation of ecosystems will, in all likelihood, result in massive human migrations with the resultant political and economic problems. The possibility of such changes occurring with further warming is very real. Depending on how rapidly warming occurs, the problems will occur sooner than currently anticipated.

Future change

The global population is now growing at a rate of about a quarter million each day. In all likelihood, this growth will continue for some time. Unless food production can increase fast enough to feed the additional growth, the number of people suffering from food shortages will increase. That climate change will take place in coming years, is certain. It should be apparent that it will be impossible to return the planet to the temperature it was in 1900 any time in the near future. When climate change is added to population growth, only the extent of future food shortage is unknown. The impact on food production will vary greatly depending on the degree of the climate change, the geographical extent of the change, and the duration of the change!

Declining Sea Ice Threatens Walruses

Walruses need Sea ice

Walruses Cling to Melting Sea Ice.

By Dr. John J. Hidore

The Rising Temperatures of the Arctic

February 22, 2014—World temperatures are warming at a record rate and the global climate is changing rapidly due to rising temperatures of our planet. Though the planet is warming, the rate at which it is warming is inconsistent from place to place. Temperature changes in the Arctic are taking place faster than anywhere else on the planet. The warming is affecting both the physical and biological character in this region. The most widely known affect is the melting of sea ice. The melting of the sea ice is significant, but the melting has many side effects.

Climate Change and the Walrus

The changing arctic climate has started to change much of the arctic wildlife. Among the species affected is the walrus. Walruses are large marine mammals that may weigh up to 2700 lbs or more. They spend nearly two-thirds of their lives in cold water. A walrus carries large tusks which are used to root out food living on the ocean floor. The tusks are also used to help move around on the slippery ocean floor. Off shore of the land masses surrounding the Arctic Ocean. the ocean floor drops slowly on what is generally referred to as the continental shelf. Beyond the edge of the continental shelf the depth to the ocean floor drops to several thousand feet in places. Walruses mainly feed on the continental shelf in water less than 300 feet deep. They will, however, feed as deep as 600 feet.

Declining Sea Ice

Sea ice plays a critical part in the lives of the walrus. Walruses cannot swim indefinitely like some seals, and must rest between forays searching for prey. They use sea ice as a platform for searching for food and as a place to rest during their annual migration. Females also use the sea ice during the summer as a place to give birth and nurse their infants. When the walruses are on the sea ice they tend to spread out over large areas. In late summer they migrate to warmer waters. In the past they tended to move onto land in late August during their migration. There are two species of walrus in the arctic. One is the Pacific walrus which inhabits the Bering, Chukchi, and Laptev seas. The other is the Atlantic walrus which is found along northeastern Canada and Greenland.

The Arctic region is now the warmest it has been in 40,000 years. The sea ice has melted to record lows. This has limited the area where walrus can haul out on the ice if it melts too far from land. When the sea ice retreats beyond the edge of the continental shelf and over deeper water, instead of hauling out onto the ice, the walruses head for land and congregate.

Walruses: Herding On Land

Huge gatherings of Pacific walrus have taken place in the last decade. In 2007, an estimated 6,000 walruses gathered along the Alaskan coast. In the fall of 2008, few walruses came on shore as some sea ice remained near shore. In September of 2009, some 3,500 Walruses were near Icy Cape on the Chuckchi Sea 140 miles southwest of Barrow. In 2011, some 30,000 congregated on a beach about a mile long. Large numbers of walruses have also been seen on shore at Cape Lisbourne. Large congregations have occurred in the years since. The same phenomenon is taking place on the Arctic coast of Russia near the Chukchi sea. Herds of tens of thousands were gathering on this coast. Near Point Schmidt, a herd of some 40,000 was sighted. The total population of Pacific walrus is not known, but estimates place it at about 200,000.

The large herds on land are a threat to the walruses. The threat comes from several sources. One is that they tend to stampede when some unusual event startles them. Individuals are often killed during the stampede. Russian biologists reported several thousand, mostly young, were crushed to death in one stampede. For example, noise from hunting weapons and polar bear attacks can cause a stampede. Pilots of small, low flying aircraft are being warned to stay away from the herds as the noise can cause them to stampede. Large gatherings in a limited space also are more favorable for the outbreak of disease. The concentration of such large numbers also has a severe effect on the clam population offshore from the herds. This extensive harvesting may result in an unsustainable population of their food supply.

The decline of sea ice and the changing environment are not only a threat to the walrus population but serve as further evidence of a warming planet. Biologists are asking for the walrus to be declared an endangered species since the outcome of declining sea ice on the species is not yet clear.

The Science of 350: How Much CO2 is in Our Atmosphere?

The Science Of 350 and the Growing amount of CO2

Every year data measures a greater amount of CO2 in our atmosphere.

By Lin Smith

The Safe Limit of CO2 for Humanity

January 20, 2014-–The science of 350: Scientists say that 350 parts per million of CO2 in our atmosphere is the safe limit, and unless we rapidly return to below 350 ppm this century, we risk reaching tipping points and irreversible impacts, such as the continued melting of the Greenland ice sheet and major methane releases from increased permafrost melt.

Up until about 200 years ago our atmosphere contained about 275 parts per million of carbon dioxide, which gave human beings the environment necessary to exist. It provided us with just enough warmth on Earth–not too hot, not too cold! Parts per million (ppm) is  a way of measuring the concentration of different gases. It means the ratio of the number of carbon dioxide molecules to all of the molecules in the atmosphere.

Atmospheric CO2 and the Industrial Revolution

Beginning in 18th century, people began to burn coal, gas, and oil to produce energy and goods. This was the Industrial Revolution of Britain, Europe, and the U.S. During this time period, CO2 began to rise in our atmosphere. The production of goods transitioned from hand made to machine made. The transition also included changing from wood and other biofuels to coal.

What is a Biofuel?

A biofuel means a fuel derived directly from living matter, such as wood, corn, ect. The CO2 released from wood and other biofuels has minimal impact on greenhouse gases. When we burn wood and other biofuels, the energy the biofuels took from the sun for photosynthesis, (remember your science classes?) is released back into the atmosphere. It takes and gives back about the same amount, thus maintaining the 275 ppm of carbon dioxide in our atmosphere-just enough for us to exist –comfortably, up until now! When we burn fossil fuels, such as coal and oil, we put more CO2 in the atmosphere than is used by earth’s vegetation. The earth then warms and that warmth is absorbed by the CO2, which does not allow it to escape into space. When CO2 is too high, climate change occurs, as it is doing today.

Reliance on Fossil Fuels

Many activities we do every day, like turning the lights on, cooking food, or heating and cooling our homes, rely on these fossil fuel energy sources that emit carbon dioxide, trapping gasses into the atmosphere. We’re taking millions of years worth of carbon, stored beneath the earth as fossil fuels, and releasing it into the atmosphere. The planet now has above 400 parts per million of CO2, and the number is rising every year. That is more than this planet has seen in its history! Scientists say the highest safe level of CO2 is 350 parts per million. This is the safety zone for planet earth!

Preserving Our Planet

James Hansen, of NASA, says if we wish to preserve a planet similar to that we are inhabiting, we need to reduce the CO2 above 400ppm to, at most, 350ppm. We need to stop taking carbon (coal) out of the ground and putting it in the air. We need to start using solar and wind and other sources of renewable energy. If we do this, then the earth’s soils and forests will slowly cycle some of the extra carbon out of the atmosphere and eventually CO2 concentrations will return to a safe level. By doing this we could go back to the 350 by 2050. But the longer we remain in the danger zone, above 350, the more likely that we will see disastrous and irreversible climate impacts!

Cutting Fossil Fuels

1. Recycle your waste. Many household wastes, including most plastics, are made from fossil fuels. Most prepackaged foods and goods use fossil fuels for their production and disposal. Try to reduce your overall consumption of things you don’t really need, and recycle everything!
2. Drive less, walk, cycle, take public transportation, or drive a hybrid vehicle. I know hybrid vehicles aren’t an economic choice  for many people, but there are a growing number of older hybrids on the market, and if you weigh the cost of purchasing one with the amount you could save in gas, it may be a good choice, for you and the environment. An older Prius may get 60 mpg, and, no, the batteries aren’t wearing out like predicted.
3. Cut your household power consumption, turn off lights when not in use. Most of the electricity in your house is likely to come from coal-fired power stations, not renewables. Insulate your home, use a ceiling fan instead of air conditioning, hang your clothes instead of tumble dry. I know–who has clothes lines anymore?? BUT they can be inexpensively installed in the back yard–just like the old days! Just put ‘em back!
4. Install a solar panel. They are getting less expensive to install and will save you money in the long run.

The Science of 350 states we must lower the CO2 in our atmosphere, even doing something small will be a start towards saving our planet for future generations!
