Earth Hour and Earth Day are Now Global Events

Earth Day, April 22, 2019

This year Earth Day has a theme which is, “Protect Our Species”.

By Dr. John J. Hidore

In the past few years unusual environmental events have changed the public perception of global warming and climate change. Not only have the majority of people now endorsed the fact the warming of the planet is real, but also that something must be done to stop the rapid change to the global climate system.

Politicians around the world, regardless of their political or economic philosophy, are being forced to take action to curb the process. They are taking action because they must deal with the effects of global warming. Whether it is rising sea level, rising global temperatures, more frequent severe storms or changing weather patterns, the problems are real! Mayors of large cities and heads of state are now recognize and realize that something must be done.

Earth Day 2019

Earth Hour

Earth Hour

On Saturday March 30, 2019, a global event took place called Earth Hour. The purpose of the event was to call attention to the rising impact of human activity on the planet. The first Earth Hour was held in Sydney, Australia on March 31, 2007 and organized by the World Wildlife Fund. They asked the people to turn off their lights for one hour from 8:30 to 9:00 pm to call attention to the increasing effects of global warming. It is estimated that more than two million individuals participated.

Support for Earth Hour can be demonstrated by turning off lights at the designated time and/or for individuals, signing a pledge to do your part. Billboards in Times Square, New York and lights on some buildings were dimmed or shut down. Many other cities around the globe also participated. It has also been suggested that there has been more grass roots participation in this event than any other organized event. Next year’s event will be held on March 28 2020.

Earth Day

The first Earth Day was held on April 22, 1970. This will be the 49th year of the event. Earth Day 2019 promises to be of major significance. This Earth Day, April 22, more national governments, non-governmental organizations, and individuals are expected to take part in scheduled activities than ever before!

This year the event has a theme which is, “Protect Our Species”. The emphasis is going to be on protecting threatened and endangered species. Today humans are responsible for the most rapid rated of extinction of species that has occurred in more than fifty million years. Prior to the impact of humans, species were disappearing at the rate of one to five species each year. The current rate is perhaps a thousand times that. It is estimated that nearly half of all animal species are in decline. Some have labeled it the Sixth Mass Extinction. A mass extinction is defined as an event in which more than half of all species become extinct.

Climate Change: The Shift in Politics and Public Opinion

“If the Green New Deal isn’t a quick fix, it is creating a conversation.”

By Linn Smith

The term Green New Deal, has currently been brought to public attention by Congresswoman, Alexandria Ocasii Cortez. But the term was originally used in the early 2000’s by Van Jones to outline his vision for a program that would birth a “just and green” economy, as written in his book, The Green Collar.

The Changing Public Opinion on Climate Change

Public opinion is changing in support of climate legislation, politicians can no longer put it on the back burner. Seventy per cent of Americans have real concern for our changing climate and have some knowledge of what’s coming down the pipeline in our future. Most people have also experienced some form of extreme weather conditions in the past several years.

The Green New Deal

If the Green New Deal isn’t a quick fix, it is creating a conversation and parts of the proposal are gaining support from both Democrats and Republicans.” An article on climate change in the recent issue of Time Magazine states, “The outcome of the debate will go a long way towards determining if humanity can avoid the most catastrophic consequences of a rapidly warming world….the science is damning and the clock is ticking!”

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.

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.

Working Toward Renewable Energy

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.

Reduce, Reuse, Offset

climate change

Only you can prevent global warming

“What can you do to help save our Planet Earth?”

By Linn Smith

November 26, 2018—–In the last several years it has been progressing….the evidence of climate change….floods, fires and extreme weather. For me, some days were difficult to breath during the summer due to smoke from the fires in the Pacific coast area.

Take Responsibility for Climate Change

Now is the time! It’s time to take personal responsibility for cutting your carbon footprint, even though politicians may be looking the other way in the name of profit from fossil fuels or under the pretense that miners, and other workers in the fossil fuel industry, need those jobs instead of being retrained in other fields.

Its time! You as an individual must reduce your carbon footprint to minimize the catastrophe our planet is headed for. Scientific fact states there is a correlation between fossil fuels, the greenhouse effect and extreme weather. Though most believe this, many are not willing to reduce their carbon footprint.

What is a carbon footprint? A Carbon footprint is “the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a particular person or group.”

Only You Can Prevent Climate Change

Everyone’s heard the slogan, “Only you can prevent forest fires!” I grew up with Smokey the Bear drilling the dangers of fire into my head! So let’s bend the slogan a little. Only you can prevent climate change! Do you need a bear telling you this??

The unfortunate thing is, even if we start today, the earth will not see the results of your effort anytime soon, but future generations may experience a slowing effect. Then why bother you ask? It’s the right thing to do! It’s a code of ethics we as humans on this earth need to adopt, even though most won’t live to see the results. It’s the greatest gift we can give our children and grandchildren!

Cutting Your Carbon Footprint

So here are a few ideas to cut your carbon footprint:

Cars have surpassed energy production in emitting CO2 into our atmosphere, as energy production has been rapidly moving towards solar, wind and other renewables. I drive an older Prius Hybrid which I intend to drive until it’s done. I can attest to the reliability of these cars, plus the fuel efficiency. I get around 50 mpg depending on how I drive it. Here is a website for finding the most fuel efficient cars on the market: https://www.consumerreports.org/fuel-economy-efficiency/the-most-fuel-efficient-cars-best-mpg/

Turn the lights off when not in use. Turn down your hot water heater. Choose solar if it’s an option. A friend has a motion solar light for outdoor use and it burns just as bright as any other light. You can find these at http://www.walmart.com You can find strings of solar Christmas lights at https://www.survivalrenewableenergy.com/20-best-solar-christmas-lights/
I have strings of solar lights outside to light my way from car to house and own a solar flashlight that works very well.

Invest in a clothesline. A friend is a full time RVer and has adapted a small clothesline for the back of his RV as seen in the photo. Be creative and resourceful!

global warming

Clothesline for rv

Buy used! Almost 30% of greenhouse gas emissions result from extracting resources, manufacturing, packaging, transporting and final disposal of consumer products. By purchasing used products and reselling them or giving them to a charity, you greatly reduce your carbon footprint.

Use a Carbon Offset

According to nativeenergy.com when someone buys a carbon offset the money goes to pay for a reduction in greenhouse gases that is part of your carbon footprint. It helps fund an existing clean energy project to offset your daily emissions of CO2.

Or here’s another thought from a friend. They travel a lot. They have down sized from a 5th wheel to a truck camper. They decided the pots, pans and all kitchen utensils in their camper should weigh no more than 30 lbs. They weighed each item before putting it in the camper to make sure the total weight of all was less than 30lbs.

Think about your own carbon producing habits and how to reduce or offset them. Be resourceful. It’s personal at this point. Each person needs to ask themselves, “What can I do to help save our Planet Earth?”

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.

“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.

The Holocene (Holocene-Anthropocene?): Earth’s Environment Since Deglaciation

Anthropocene

Anthropocene and human impact

“With the advent of agriculture, human alteration of the environment began to take place quite rapidly.”

By Dr. John J. Hidore

July 30, 2018—-The Holocene is the last currently recognized geological epoch. Holocene means “entirely recent.” It is also the shortest. As between other epochs interconnected events mark the boundary between the Pleistocene and the Holocene. Climatic change was a key factor at the boundary. Toward the end of the long retreat of the ice, the climate alternated between warm and cold. The ice sheets began to melt rapidly about 14,000 years ago.

During the initial phase of melting in North America the water created two rivers now known as the Missouri and Ohio. These two rivers formed at the front of the ice sheet. These rivers joined into what is now the Mississippi River. The volume of water in the Mississippi must have been tremendous based on the width of the Mississippi River Valley. So much fresh water flowed into the Gulf of Mexico that it altered both the salinity and temperature of the Gulf.

As the sea ice melted in the Atlantic, the southern limit retreated northward allowing warmer water from tropical regions to flow further North. The clockwise circulation around the North Atlantic including the Gulf stream developed. The weather patterns around the North Atlantic Ocean came into existence that were much like those of today.

Anthropocene

Lessons from the fossil record: Discarded consumer good. anthropocene layer in the rock strata.

Younger Dryas Event

By 11,500 years ago, only scattered areas of ice sheets remained in western North America. The main ice sheet was in eastern Canada. Real warming of the northern hemisphere could not take place until most of the ice had melted. However, at about this time a fairly rapid reversal of the melting took place. The edges of the ice sheet moved towards the equator once again and some small ice sheets reappeared. This cold period became known as the Younger Dryas event, (named for a small flower found in cold climates). The warming was not a global event. It took place mainly around the North Atlantic Ocean. Evidence of glacial ice at this time is found largely on Greenland, maritime Canada, and northern Europe.

Anthropocene

The human impact on our earth.

Climatic Optimum

Seven thousand years ago conditions had warmed again such that only remnants of the ice sheet remained. The warming peaked about 5500 years ago. Basically, only the Greenland ice sheet and the ice on the Antarctic continent remained. Although it varied in intensity and timing from place to place, the warming was a global event. Mean atmospheric temperatures were warmer than today and the term climatic optimum or thermal maximum was coined to describe this period. In Europe temperatures averaged two to three degrees Celsius (5 ½º F) above the present. There the tree line was some 100 meters (330 ft) above that of today. In Africa there was a rapid drying and expansion of the Sahara Desert. Evidence indicates a major migration out of settlements in the region as food supplies dwindled. Remnants of these settlements are scattered over much of the region.

Anthropocene

The human impact on Earth.

Anthropocene (?)

The Anthropocene is the name given to a recently proposed epoch that coincides with the impact of the human species on our planet. Boundaries between epochs have been placed where there was a significant change in the environment. There is justification for the creation of the new epoch. With the advent of agriculture, human alteration of the environment began to take place quite rapidly.

A major problem is that there is no agreement as to where the boundary should be placed. Some argue that it should be placed at the beginning of the Holocene some 14,000 years ago. Others advocate placing it at the beginning of the Industrial Revolution around 1780.

There seems to be agreement that the Anthropocene, if it becomes a recognized epoch, should coincide with some stage in the technological development of the human species. The recognition of the Anthropocene as an epoch is yet to be determined.

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.
