CLIMATE CHANGE, DROUGHT AND FAMINE

Some species may become extinct

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

“Climate change is the current cause of drought and famine.”

By Dr. John J. Hidore

December 10, 2018—There are many causes of famine, but one of the major ones is drought. Most of the past catastrophic famines have been precipitated by drought resulting from short term shifts in the atmospheric circulation.

Crop Yield and Drought

Drought generally occurs when there is a short-term lack of precipitation lasting more then one growing season. They are the most common in regions which have a pronounced seasonal rainfall regime. Drought affects the quality and quantity of crop yields and the food supply for domestic animals. During severe droughts there may be a great loss of domestic animals. The loss of milk products or meat increases the impact of drought.

Climate Change

Our Food Supply may be Rapidly Reduced with Rises in Temperatures.

Great famines have occurred throughout the Asian continent from the time that agriculture spread over the continent. China, India, Russia, and many middle-east countries have suffered frequently from famine resulting from drought. A famine is described as occurring during the time of Abraham, about 2247 BC. A 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 at least to 400 B.C. and in China to 108 B.C. From the time of the earliest known famine there have been nearly continuous episodes of drought and famine in some part of the region. Other regions experience droughts as well. It should be mentioned here that what is often referred to as The Great Famine occurred in Europe in the period from 1315-1317.

Eighteenth Century Drought and Famine in India

In the mid-eighteenth century the people of India were largely subsistence farmers. It was primarily crop agriculture based on the whims of the monsoons. The country was under the control of the British East India Company, which kept the farmers on the verge of starvation under the best of conditions. Because of the general poverty of the masses and the marginal nature of the food supply, only a small shortfall in the crops in a given year produced scattered starvation. India is a huge country, and at the time only a ponderous transportation system existed. There was no means of moving large quantities of food, nor of moving large numbers of people to areas where food was available. When drought set in there were few alternatives to starvation available.

Drought and Famine: 1768

In the summer of 1768 there was little rain and crops were poor. The drought continued into 1769. Famine was apparent in the northern parts of Bengal by November 1769. By April 1770 over 30 million people in West Bengal and Bihar were affected. Fatalities were estimated at upwards of 10 million. The deaths were the result of both starvation and disease. Smallpox became epidemic along with the drought. The death toll from this famine is the highest known from any famine up to this time.

Famine has often been a problem in some part of the world since this event. As with this one, short term climate change has been the primary cause.

Cities Accept the Challenge of Climate Change

“It seems clear now that political organizations other than national governments are going to lead in taking actions to reducing climate change.”

Sustainable living

It’s our responsibility to change.

By Dr. John J. Hidore

November 19, 2018—–Earth’s climate has been changing from the time the planet came into being. It has gone through times when it was much warmer than today and others when it was colder. The climate of today is one that is inseparable from the growth of the human population. The industrial revolution began about 1770 AD and is synonymous with the advent of the steam engine. Steam engines burned fossil fuels, primarily wood or coal.

Planet earth is a single system in which nothing or no process exists in isolation. The burning of fossil fuels began to change the composition of the atmosphere. The temperature of Earth began to warm above what might be expected from natural causes and the term global warming started to appear in literature. Professional conferences by groups of scientists and others began to occur.

In 2015 an international conference on climate change was convened in Paris, France to discuss the problems associated with a changing climate. What is known as the Paris Agreement was ultimately approved by representatives of nearly 200 countries. However, the Agreement does not dictate any actions to be taken by the signatories. Many have done little or nothing concrete to stem climate change

Sierra Club

Sierra Club for Clean Air

Cities, Provinces and Other Regional Governments Take Charge

Many homogeneous political units such as cities, states or provinces began to respond to climate change because governments of these units began dealing with problems of flooding, unhealthy air to breath, increasing heat, etc.

Cities and towns are home to the majority of people now living on the planet. The number living in cities is growing by more than a million each week. By mid-century the percentage of people living in urban areas is estimated to reach 70%.

Groups of cities are now actively working together to reduce greenhouse emissions. As of June 6, 2018, approximately 250 mayors of American cities have officially adopted the Paris agreement. These cities contain about 60 million people. They are part of a group called Mayors National Climate Action Agenda. Among the cities that have agreed to support the Paris Agreement is Pittsburgh, Pennsylvania. This is the very city where U.S. President Trump stated he did not represent Paris and might withdraw the United States from the agreement.

building green

Cities, states and individuals must do their part in preventing climate change.

Reducing Carbon Emissions

Perhaps the most concerted effort being made is to reduce carbon emissions. Carbon dioxide (CO2) is the primary gas in the absorption of energy in the atmosphere. Cities account for about 70% of carbon dioxide emissions. A major part of the effort to reduce emissions is reducing carbon emissions from motor vehicles. Another is switching to renewable fuels for generating electricity. This means eliminating power plants using fossil fuels.

The Sierra Club recently estimated that encouraged by their Beyond Coal campaign, coal-fired power plants have been closing at times at the rate of one every 16 days. This month representatives from more than 70 countries are gathering in Edmonton, Canada, to explore how to develop cities that can create and maintain a climate that adds a minimal of carbon to the atmosphere.

While some national governments, such as that of the United States, refute the whole concept of climate change and do not want to take any action, the people are taking combined action through more localized governments. It seems clear now that political organizations other than national governments are going to lead in taking actions to reducing climate change.

Newsworthy Renewables

Boyan Slat

Slat looks over his System 001.

“At this point, cleaning up our planet can’t be left to someone else!”

By Linn Smith

November 13, 2018—-While leafing through renewable resource articles recently, I found many positive activities happening in an effort to counteract climate change. Now that most people have acknowledged climate change is real, renewables will continue to grow in 2019.

Weather extremes are affecting people in many countries. Someone said, “People won’t change until it’s in their own backyard.” Well, in the form of floods and fires, it is in many people’s backyard. It’s a harsh wake-up call by mother nature!

New With Renewables

So here are a few positives that are happening in the renewable resource area:

1. According to Reuters.com, “The Paris region plans to launch a large fleet of electric bicycles in a state-funded scheme aimed at getting commuters to cycle to work and reducing congestion and pollution. They will provide 10,000 electric bikes for long-term rental, eventually expanding to 20,000.”

renewable resources

Paris will add thousands to the streets.

2. According to electrec.co, “Canada will have the first all-electric ferries serving the area in Ontario. A battery pack will be installed on board to power the propellers and a diesel generator will serve as a back-up.”

3. TheGuardian.com states that, “Uber drivers in London will be banned from using vehicles that are not hybrid or fully electric in 2020 as part of a plan to help tackle illegal levels of air pollution in the capital.”

4. Treehugger.com says that, “The European based Easyjet will incorporate electric passenger planes into services within 10 years.”

5. And Tesla is coming out with a new pickup truck in 2019. According to Elon Musk the Tesla pickup will be large, maybe even as large as the Ford F150, a full sized electric pickup truck!

renewable resources

The truck of the future!

6. My favorite in trying to make our planet a better place, 24-year-old Boyan Slat created the nonprofit, the Ocean Cleanup, which is currently in the Great Pacific Garbage Patch trying to perfect Wilson, the system created to clean up the plastics in the ocean!

At this point cleaning up our planet can’t be left to someone else. It is everyone’s responsibility. Find a way to be some small part of the cleanup effort!

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.

Indian drought

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.

Boyan Slat and the Ocean Clean Up Project

Boyan Slat

Slat looks over his System 001.

“The System 001 is an unmanned system moving with the currents.”

By Linn Smith

October 7, 2018—–If you’re not following Boyan Slat’s attempt to cleanup the Great Pacific Garbage Patch (GPGP), you should be! This young man put his heart and soul into this project and is currently headed for the great patch of garbage floating in the ocean.

#Boyan Slat

Garbage Patch swirls with the currents.

The Great Pacific Garbage Patch

Slat is the poster child of sustainable innovation for his generation, putting his energy towards cleaning up the environmental mess past generations have created! According to some critics he may not have the perfect solution—but, who else is in the middle of the ocean right now trying?? Hummm, no one! And the mess has been floating and growing for years! Scientists have estimated the Garbage Patch would take 79,000 years to break down and dissolve in the ocean! With the models created by Slat, his system could clean up 50% of the mess by 2025! The majority of the Garbage Patch is large debris. Removing these floating pieces of plastic will prevent the breaking down into microplastics that wildlife and fish can mistake for food and eventually entering the food we eat.

Boyan Slat

Boyan Slat

Boyan Slat

Boyan Slat is 24 years old and the garbage patch is almost as old as he is. By the time it was discovered in 1997, it was already massive. At 16, this Nederland’s born youth went on a diving trip to Greece. “There were more plastic bags than fish,” he told MNN a few years back. “That was the moment I realized it was a huge issue and that environmental issues are really the biggest problems my generation will face.”

Instead of accepting the floating plastic as an adult problem that needs an adult solution, he went back to his high school and went to work solving the problem. Back in his high school classroom he invented a multilevel trawl with centrifugal forces that separated the plastic from the plankton and ocean life.

Boyan Slat

The Ocean Cleanup

System 001

“The System 001 is an unmanned system moving with the currents, looking like a u-shaped pipeline floating on top of the current. Beneath the pipeline is a 10 ft skirt which traps the plastic caught in the current, protecting sea life because it is solid and not a net.” Slat states, “Our systems fully rely on natural ocean currents and do not require an external energy source to catch and concentrate the plastic. All electronics used, such as lights, will be solar powered.

Big Solutions for the ocean cleanup

Recycling the Ocean Plastic

What will happen to the plastic when it’s back on shore? Slat says he wants to turn it into The Ocean Cleanup brand of merchandise, selling it to support the cleanup of the Great Pacific Garbage Patch. He states, “By producing merchandise that is not a single use item that might end up back in the ocean, it will reduce the chance of it ending up back in the ocean by 99%.”

Slat also humbly states, “Big problems require big solutions, if anyone has any better ideas, we’d love to know!”

This young man has the concentrated and innovative talent our planet needs!

E-Waste: What Happens to those Electronics?

Renewable Resources

Building Sustainably

“E-waste does not belong in the landfills!”

By Linn Smith

October 1, 2018—Do you have a computer? Smart phone? Laptop? Half of the world’s population now uses the internet. In developed countries, nearly 90% of the population own some form of technology and many people race to get the latest up-to-date gadget without any thought of end-of-life disposal of that cell phone, laptop, or computer! There is no budget attached to the item purchased that reminds us of the need to recycle it, but what if we had to pay an extra 20% fee on the purchased item for recycling? Would that make you stop and think about its disposal?

In 2016, all countries combined generated 44.7 million metric tons of electronic waste. And where did it go? 4% was thrown in the trash, 76% was undocumented and just 20% was properly recycled.

The earth continues to warm

Fight against global warming!

Proper Recycling of E-Waste

What is proper recycling? Recycling electronics can be difficult because removing the wanted rare earth metals means removing glass, toxic metals, plastic and soldered connectors. Proper recycling is taking your unwanted e-waste to a certified company. A certified company has been audited to make sure the company is following strict regulations in compliance with state regulations.

Recycling electronics costs money, but often finding a certified company can cost less because the recycle center may receive subsidies from the local government. If the company isn’t certified you don’t know where your e-waste may end up. E-waste can create huge environmental hazards if not properly disposed of as it contains lead, mercury, cadmium and other toxins. Many uncertified companies are using unsafe methods to extract the wanted metals.

Earth Day

Clean Energy: Make It a Priority!

E-Waste: Thailand

China use to take e-waste, but now much of it goes to Thailand where environmental groups have submitted a letter to the government demanding that the government ban imports of toxic waste. Many factories in Thailand are using the unsafe method of burning the plastics of the electronics to get to the copper, gold, platinum and rare metals, creating toxic fumes in surrounding residential areas.

Rick Neitzel, Director of Exposure Research at University of Michigan, says, “As most users grow dependent on their cell phones, laptops, computers and tablets, the production of electronic waste continues to grow.” His team studied the toxins entering the bodies of workers in contact with metals from electronics, measuring the amount of lead and other toxins that find their way into the bloodstream. The blood tests show high levels of toxins!

Urban Mining: Used Metals

Some electronic manufacturers are using recycled metals from out-of-date electronics in manufacturing new phones. DELL will recycle 100 million pounds of e-waste by 2020 and Apple has developed a robot to take apart old Iphones, dissembling 200 Iphones in an hour and sorting the parts for recycling. The goal of Apple is to completely eliminate new rare metals from its manufactured Iphones, using only recycled metals (Urban Mining). An Apple representative states, “The challenge is to extract the metals at a cost that can compete with virgin metals in sufficient quantities.”

In Chili the attitude is to fix things because they figure they can make more money reselling a product than selling recycled parts.

Clayton Miller of http://www.Sustainablebrands.com states,”In the early days of my career I spent a good part of my time explaining to people what e-waste was, that it was hazardous and that it shouldn’t be in the landfills, but today I find that the majority of people want to ensure their discarded electronics are properly recycled.”

Irrigation and Water Depletion in the Southwest United States

Water depletion

Irrigation in the Southwest U.S.

“We need to work together to feed the world, but we also need to work together to save and monitor our water resources.”

By Linn Smith

August 26, 2018—- On the farmland of my youth in the Midwest, my brothers and I spent much time baling hay for our cattle, but water was plentiful and plants thrived with no irrigation. Cows were in green pastures in the summertime and in winter months we fed hay when grasses died.

Farming in the Southwest

When traveling to southern New Mexico and southern Arizona, I often see hay and cotton fields in the middle of the desert and semi arid terrain. It seems an unlikely place to grow crops that have high water needs! 

Today the Southwest is water-stressed with many lawsuits taking place, both privately and between states, over water rights. The projection is that reduced precipitation by mid-century will result in reduced runoff into the water basins that feed irrigated fields.

I recently heard a local resident from Arizona say that Saudi Arabia was buying land in Arizona and California’s arid landscape for growing hay and shipping it back to their country. The export of hay (grasses grown for feeding animals) is booming in the U. S., with the amount of hay leaving the west coast ports increasing yearly. In 2017, the total exports of alfalfa and other hay reached 4.2 million metric tons and is continuing to grow.

The fact that hay and cotton are being exported is healthy for our economy, as many U.S. farmers are growing and exporting this commodity, mostly from states that require little irrigation for agriculture. The issue is growing crops in the desert Southwest in what is fast becoming an area where water is not replenishing itself in the rivers and reservoirs.

The Colorado river

Farmers in the Southwest are left little water for irrigation.

Depletion of our Water Resources

What is healthy for our aquifers and rivers when they are not replenishing? Doug Kenny, Director of the Western Water Policy Program at University of Colorado, says about potential water shortage. “Right now, it’s the effort to maintain the levels of water stored in the big reservoirs, Lake Mead and Lake Powell. They’re about half full, which is about as low as they can go before mandatory cuts in water deliveries. It’s a math problem—managing water coming in vs. water going out. So far this century, people have pulled more water out than consistently flows in. That has to change.”

Saudi Arabia and the Southwest

 Most crops will only thrive with irrigation in the arid Southwest.  Saudi Arabia is confronting a major depletion in its aquifers which has brought its wheat and hay production to a halt. They have bought 1,000’s of acres in arid parts of the U.S., Arizona and Southern California (and several other countries), allowing them to take advantage of the U.S. water laws. The Laws of the Colorado River are currently under scrutiny by the Upper and Lower Basin states because of continuing depletion of the river and Lake Mead, which supplies water to the lower Colorado river basin states. Most crops will only thrive with irrigation in the arid Southwest.

The drought of Southwest U.S.

Lake Mead depletion

Southern California: Irrigating Crops vs Urban Use

In Southern California the Metropolitan Water District pays landowners to fallow their land, letting it lay without planting crops so that water is freed up for urban areas. Since 2005, over $200 million has been paid to farmers not to grow crops on this program. This allows water to be directed to Los Angeles and other cities in Southern California.

Has this program enabled corruption and profit from drought conditions? A single recipient, Fisher Ranch, owned by a board member of the operation, has received over $27 million a year since 2005 for leaving his land fallow.

Depletion of water for crop irrigation

The Water Crisis

As I continue to study depleting water conditions in the Western U.S., I realize in 20 years, if not sooner, we are going to be facing a water crisis due to climate change and over allotment of water rights and usage. We need to ask ourselves what changes are necessary today to alleviate the impending crisis.

Water shortage is going to be a complex problem in the future requiring many people to make sacrifices. We need to work together to feed the world, but we also need to work together to save and monitor our water resources. Education and awareness is a place to start.

Pollinator Prairies and Highways: Feeding the Bees!

Pollinators

Pollinator habitats are necessary for our food sources.

“Pollinators, especially bees, are responsible for producing 1/3 of the food we eat.”

By Linn Smith
August 6, 2018—-In May 2018, Interstate 76, which stretches through the high plains farmland east of Denver, Colorado for about 185 miles, was designated a Pollinator Highway. The Pollinator Highway Project will not only be planted with food for pollinator insects, but also maintain the health of pollinator plants already growing along the highway.

I have traveled this stretch of highway many times and have always wondered at the vastness of the landscape in this sparsely populated part of Colorado. With almost 9000 miles of highway corridors in the state, I-76 is the perfect test area for the Pollinator Program. The program was initiated by Denver’s Butterfly Pavilion because it is a highway that is not only frequented by migrating butterflies, but also has enough space to eventually create a positive change in our environment by providing food for all pollinating insects.

Pollinator insects

Maintaining the health of our pollinator insects.

Definition of a Pollinator

What is a pollinator? According to the Iowa Department of Natural Resources, “A pollinator is any organism that helps with the cross-pollination of plants. They are vital to the survival of most of the world’s ecosystems, with an estimated 70-87% of flowering plants relying on pollinators. Many of these plants are food crops that humans rely upon and most of the others are key members of natural ecosystems. Bottomline: Pollinators are extremely important!”

Pollinators

Pollinator Prairies and highways

Colorado Pollinator Highway

For CDOT, Colorado Dept. of Transportation, this is a great opportunity to begin positive environmental changes using the space along its highways, replenishing and creating habitats for pollinators, such as bees, butterflies, moths, flies, bats, and hummingbirds. This will affect the future food supply of humans, as it’s said that 1 out of 3 bites of food we eat depends on pollinators. CDOT has stated that the pollinator plants along the highway will not affect travel, as the insects will stay in their habitat if it is well maintained.

Colorado will begin this project by planting an 8 mile stretch along I-76 near Julesburg, just over the state line from Nebraska. This test site will allow CDOT to gather data for plans on maintenance and longevity of future pollinator highways in the state. Besides creating habitats for pollinators, the pollinator highways will reduce maintenance in Colorado by reduced mowing. It is a win-win plan for the future.

If the dilemma of pollinator insect die-off is not addressed now, the future of the food we eat and the low prices we pay are in jeopardy. The decline of pollinators is due primarily to land use changes, pesticide use, invasive species, and climate change which can cause insect diseases and loss of habitat. According to CDOT, 30% of the honeybee population dies off yearly (with only a slight increase after die-off each year.) At this rate, the bee population is not sustainable in the long run.

Insect Pollination

Identify Plant Forage for pollinators

Protecting the Pollinator Habitat

The Colorado Department of Transportation will also be working to protect the pollinator habitat as a long-term solution for survival of pollinator insects. CDOT states, “Managing noxious weeds will also be more specialized along the corridor. In fact, we will have a roadside manager for the corridor, who will also oversee the statewide vegetation management program. The pollinator program will promote genetically appropriate plants that support self-sustaining dynamic ecosystems, which are resistant to invasion by non-native or invasive species.”

A variety of plants will be planted that will blossom at different times in the spring, summer and fall, creating food until the insects lie dormant (slow down) for the winter.

Pollinator Prairie

My friend’s well maintained prairie in the Midwest.

Pollinator Prairies

In the Midwest farmers are taking advantage of the CP-42 Pollinator Enhancement (PDF) program which helps and supports farmers that place part of their farmland in pollinator prairie. So far hundreds of thousands of acres have been planted in the CP-42 program.

A friend of mine has planted about 50 acres in pollinator prairie. He maintains it by going through on a regular basis and digging up invasive plants, such as small elm saplings. His land is near the river where the bottom part of the prairie floods several times a year, which hasn’t affected the pollinator plants so far, as they are not underwater for any length of time. He states, ““Once floodplain land is taken out of crop production and returned to natural prairie (pollinator Prairie), it acts as a very good filter in not only cleaning up dirty water ways, but preventing further flooding inland. Our rivers are dirty and prairie grass can act as a filter by allowing the water to run through the grasses.”

My friend’s well maintained pollinator prairie grass

Pollinators, especially bees, are responsible for producing 1/3 of the food we eat. What are the foods that need or benefit from pollination? Here are just a few: alfalfa (which can feed our meat and milk sources!), apples, berries, bananas, tomatoes, chocolate (Cocoa Bean trees) and coconut.

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 Arctic Basin: Warming Faster than the Planet in its Entirety

Arctic Ocean

Melting of the Arctic Sea Ice

“The arctic basin is warming faster than most of the earth’s surface.”

By Dr. John J. Hidore
June 8, 2018—–The Arctic Basin consists of the Arctic Sea and the surrounding land. The climate of the basin is warming faster than any other area of Earth’s surface. Air temperature over the arctic has increased an average of nearly three degrees Celsius (five degrees Fahrenheit) over the last century. This is almost double that of the global average.

The Energy Exchange in Change of State Between Ice and Water

One very important feature of the energy balance distinguishes the Arctic Basin. Over 95% of the earth’s surface, the major change in the state of water in the environment is between liquid and gas. This entails evaporation and condensation. In the Arctic it is between solid and liquid. There is an energy exchange of about 80 calories per gram between solid and liquid. For the rest of the earth the energy exchange is much higher. The energy exchange between liquid and gas is 590 calories per gram. This is nearly seven times that of ice and water.

The implication of this is that melting or freezing takes place with relative small changes in heat added or heat lost in the environment!

Energy Exchange in the Tundra

Surrounding the Arctic sea is a grassland, generally known as the tundra. Such a grassland is found primarily only in the Northern Hemisphere. The southern margin of the tundra is delimited by the polar margin of a coniferous forest. Specific regions that contain tundra are the northern coast of North America, Iceland, Spitsbergen, coastal Greenland, and the Arctic borderlands of Eurasia.

A significant feature of the tundra is permafrost. Permafrost is permanently frozen ground. Extensive area of land in the basin are covered with it. Permafrost can vary from centimeters to many meters thick.

Ice and snow are highly reflective of solar radiation. However, in the summer months some of the solar radiation melts the permafrost. The surface layer of permafrost thaws leaving the deeper layer frozen. The result is that lakes and ponds are a characteristic of the tundra. Once the permafrost melts at the surface, the wet ground absorbs much more radiation and the thawing increases. However, except on the margins of the permafrost, there remains frozen ground beneath the surface.

How deep the permafrost melts will vary. The point is that once the surface thaws the solar energy that is absorbed goes up substantially. This in turn increases the rate of the thawing of the permafrost. As the earth’s atmosphere slowly warms this process is being accelerated.

The exchange of energy is causing rapid arctic melting.

Energy Exchange in the Arctic Sea

The Arctic Sea is a part of the world ocean that is frozen much of the year but increasingly is open during the summer months. The season when melting occurs has increased by three weeks since records began. At present, even in the summer, there is a large area that remains frozen. As the atmosphere slowly warms more of the ice cover melts. Open water absorbs much more radiation than the ice and this increases the temperature of the water which then increases melting of the ice. As a result, over recent decades, the sea ice has been thinning or melting entirely over large areas. Just as on land the conversion from sea ice to open water is increasing at an increasing rate.

The rapidly melting artic

In summary, the arctic basin is warming faster than most of the earth’s surface. Part of the explanation lies in the fact that the amount of energy it takes to change the state of water between solid and liquid is much less than it takes to change the state between liquid to gas. There is thus a net gain in heat that is proportionately higher than that of the rest of the planet. As the summer season increases in length more heat is absorbed in the environment adding to the general global warming!
