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.

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. 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!

Recent Events of Note—January, 2018

Sierra Club

Sierra Club for Clean Air

“Jerry Brown led the planning for a Climate Action Summit to be held in September 2018.”

By Dr. John J. Hidore

The Politics of Climate Change

President Trump stated campaigning that he would take the United States out of the Paris Agreement of December 2016. He began the process soon after elected. As a result, two things happened. It rallied the rest of the world governments to act more decidedly to curb greenhouse gas emissions. In the summer meeting of the G20 countries, all except the United States confirmed their commitments to the Paris Agreement. The country of Sweden has committed to carbon neutrality by 2045. Germany has pledged to reduce carbon emissions by 40% by 2020 and 80% by 2050.

The second thing that happened as a result of the U.S. backing out of the Paris Agreement…..it united many cities, states, and people to join the forces to slow global warming and climate change. It also lead to the formation of new non-governmental organizations pledge to fight climate change. In the United States new groups include America’s Pledge and We are still in. A recently formed group known as the Global Covenant of Mayors has more than 7000 members worldwide. In the summer of 2017 governor Jerry Brown led the planning for a Climate Action Summit to be held in September 2018.

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

Climate Events of Note

A number of environmental events occurred recently that made climate change real to many who had questioned it. They include unusually high temperatures. Evidence indicates the earth is now the warmest it has been in the last 650,000 years. The winter of 2016-2017 was unusually warm. Temperatures were as much as 35°F (19.5°C) above the 30 year average. Record high temperatures occurred in many countries including the United States. In 2017 a record high of 129 °F (60°C) was recorded in the city of Ahvas, Iran.

In the past several decades the temperature in Phoenix, Arizona at the metropolitan airport has reached such high temperatures that air traffic has been curtailed or stopped for some hours. The reason is that the air over the runway became too thin for large aircraft to get enough lift to ensure becoming airborne. In the summer of 2017 such an event took place. The temperature at the airport weather station reached 119°F (84°C).

I experienced a similar incident that occurred at the airport in Lagos, Nigeria many years ago. The asphalt on the field became so warm and soft on a hot day that the wheels of a large cargo plane sank through the tarmac.

The last climate event to note…..the 2017 tropical storm season was marked by severe storms in several regions. Category four or five storms occurred in the North Atlantic region and in the Northwest Pacific region. Two category four hurricanes reached the United States. It is the first time two storms of this severity have reached the U.S in a single hurricane season!

Climate Change Over Geological Time

Glacial Ages and Climate

Climate Change Over Time

“Climate change at the present is of great consequence to most species including humans.

By Dr. John J. Hidore

November 15, 2017—-Planet Earth was formed about 4.5 billion years ago. Geologists have divided this long history of the planet into several pieces called eras. They are the Precambrian, Paleozoic, Mesozoic, and Cenozoic.

The Precambrian is the longest and each of the other three are shorter than the previous one. When considering climate change through geologic time, two aspects stand out. The first is that for most of geologic time Earth has been warmer than it is at present. How much warmer varied through time. The second feature that stands out is the intermittent ice ages when large portions of the earth were covered with ice.

Major Ice Ages

Relatively little is known about the long period of Precambrian time. Basically it was the period during which the earth cooled from its initial very hot state. The Paleozoic, Mesozoic, and Cenozoic eras encompass the rest of geologic time, about 570 million years. More evidence, and a greater variety of
evidence, is available about the environment during these eras. The climate of Earth varied widely during this time. However, it has been established that there were three known periods of glaciation in Precambrian time. They were:

Archeozoic 2250 million years ago (mya)
Early Precambrian: 950 million years ago
Late Precambrian: 750 million years ago

There were four major glaciations following that of the Precambrian era. They were:

Early Cambrian: 650 mya
Ordovician: 450 mya
Permo-Carboniferous: 350-250 mya
Pleistocene: 1.8 mya until recent time

Following the ice age at the end of the Precambrian, the earth rapidly warmed. For the remainder of the history of the earth, temperatures have averaged 5 degrees C (9°F) higher than at the present. These warmer conditions existed probably 90 percent of the time over the past 570 million years.

The Permo-carboniferous Ice Age

An ice age, called the Permo-carboniferous, began at the end of the Paleozoic Era. It began about 325 million years ago and lasted until about 250 million years ago. The South Pole was in the midst of the large land mass called Gondwanaland. Ice sheets moved over about half of this large land mass. What is now Antarctica and parts of Australia, India, Africa, and South America were covered with ice. The glaciation of each of these areas did not take place at precisely the same time, but they were all affected by the same climatic cooling. The Southern Hemisphere suffered widespread glaciation, but the Northern Hemisphere remained warm. The most appealing explanation for this situation is a different relative location of the land masses. The northern continents were nearer the equator and the southern land masses nearer the poles.

Climate Change

Climate Change over time.

The Warming of the Earth

After the glaciation in the Permo-Carboniferous ice age, the earth again entered a long period of warm conditions. The period of warmth continued through most of the Mesozoic Era and the earth was free of glaciation. Temperatures were warm and rainfall was abundant on the land masses. Even the polar regions experienced mild weather. Initially, the warmer conditions resulted from the slow migrations of the large southern hemisphere land mass to the north. This carried areas that had been glaciated into warmer climates.

The Pleistocene Ice Age

The most important single environmental event since the human species has been on earth has been the oscillation between glaciation and interglacials during the Pleistocene Epoch. The epoch represents a large change from much of the last 570 million years. This ice age is the most recent of the major cold periods to occur over the history of the planet. During the time when the ice was most extensive over Earth, temperatures averaged about 4°C (7°F ) lower than those of the present. In the northern hemisphere it was perhaps 8 to 12 °C ( 14 to 22°F) lower than current temperatures. 

There is no question but what the climate of planet earth has changed frequently, and sometimes drastically, over geologic time.

Climate Change Today

Climate change at the present is of great consequence to most species including humans. There is really no way of knowing how much change will take place in the foreseeable future nor how much is due to the activity of our species. What is known is the earth is warming rapidly at this time and that all evidence points to human activity as bearing the responsibility.

Now is the time to take international action and not only support the Paris Agreement, but take even more drastic measures to curtain the warming!

Storms: Global Warming Sets 21st Century Record

Hurricanes

Hurricane off the shore of the U.S.

“The prognosis is for these marine storms to become more intense with time.”

By Dr. John J. Hidore

October 2, 2017—-In the many years since global warming and climate change became recognized as a global problem, it has been forecast that severe storms would become more severe. The severity of hurricanes in the 21st Century supports this forecast.

North Atlantic Hurricanes

Hurricanes occur in many parts of the world’s oceans and go by different names in different regions.
In the North Atlantic and South Atlantic Oceans, they are called hurricanes. In the North Atlantic, the hurricane season runs from June 1 to November 30 and most hurricanes occur during this period.

In 2017, the first storm to reach hurricane strength was Arlene on April 19, well before the normal season begins. It was only the second named storm to occur in April since records began. This year, in 2017, is the first time that two hurricanes of category four reached the United States. Both of these were Atlantic hurricanes. If the recent hurricane that struck Puerto Rico is included it raises that number to three.

South Atlantic Hurricanes

Hurricanes are rare in the Atlantic Ocean south of the equator. Many tropical lows develop in this region, but Hurricane Catarina, in 2004, was the first and only tropical depression in history to reach hurricane status in this part of the global ocean.

Hurricanes

Heavy hurricane winds threaten the coast.

North Pacific Severe Storms

The northern Pacific Ocean is divided into two regions for naming severe cyclonic storms. North of the Equator and East of the International Date Line at 180 degrees, they are hurricanes. The eastern Pacific hurricane season begins earlier than does the Atlantic season. It runs from May 15 through November. In 2017, the first system to reach tropical storm status was Adrian and developed on May 9, the earliest on record. However, it did not reach hurricane strength.

The northwest Pacific region extends from 100 degrees East to the International date line. In this region the storms are referred to as typhoons. Most of the worst typhoons on record have occurred in the 21st Century. This is particularly true when fatalities indicate the severity. The Philippine Islands lie in the path of these storms. Between five and ten tropical cyclones make landfall in the islands each year. Haiyan, in 2013, was the most severe on record, taking more than 6000 lives and displacing several million people. The local name for the storm was Typhoon Yolanda. The first typhoon of 2017 formed on January 7. Typhoon Noru formed in July and became a Category 5, or super typhoon.

Hurricanes

The eye of the hurricane

Indian Ocean Cyclones

In the Indian Ocean and western parts of the South Pacific region, these storms are called cyclones. In 2015 Cyclone Pam reached a Category 5 status with sustained winds of 160 mph

The Coming Years

Climate change, and particularly warmer water in the Pacific Ocean are most certainly contributing to the increased severity of the storm. The prognosis is for these marine storms to become more intense with time.

Americans Still Support The Paris Climate Agreement

building green

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

“People are publicly demanding that their local governments cut energy use and change to less carbon based sources of energy.”

By John J. Hidore

June 10, 2017—-Evidence indicates that the earth is now the warmest it has been in the last 650,000 years. Data also indicates the 20th Century was the warmest century in the past 1000 years. Most of the warmest years on record have occurred since the beginning of the year 2000. Climate change is now taking place faster and faster and is responsible for historic catastrophes around the world. It is clear to the majority of human beings inhabiting this planet that there is a serious change taking place in our weather and climate.

The Paris Climate Conference

In the fall of 2015 the historic Paris Climate Conference-Cop21 was held. Out of that conference came what is generally known as the Paris agreement. The main goal of the group is to keep the mean temperature of Earth from increasing less than 2 degrees C (3.6 degrees F) above the pre-industrial average temperature. It has already risen about half that. This means keeping the global temperature from rising no more than another 1 degree C (1.8 degree F). Reducing it this much would bring the level of carbon dioxide back to where it was at the beginning of the industrial revolution.

An agreement was finalized on December 12. The group committed to keeping the global temperature rise to 1 degree C (1.8 degree F) by the year 2100. A key difference in this agreement from previous agreements is that each individual country could set its own goals for reducing greenhouse gas emissions. The agreement imposes no penalties for countries which do not meet their own goals.

Prior conferences wanted to set the goals for each country. Some poor countries still wanted the richest countries to bear the biggest share of the cost or to make the biggest cuts in carbon emissions. The wealthier countries did commit $100 billion a year to help pay the costs for the poorest countries.

climate change

There is a lot of hard work to be done after withdrawing from the Cop21 agreement.

America Withdraws from the Paris Climate Agreement

Donald Trump stated he would take America out of the agreement. During the presidential campaign, he declared that climate change was a hoax. He also stated that if elected he would take the United States out of the 2015 Paris Accord. On Thursday, June 1, 2017, the president of the United States announced that he was withdrawing the United States from the Paris Agreement. The reason he gave was that the agreement was unfair to this country. That this decision on his part has trashed America’s image abroad is an understatement. The United States, up to this point, had been leading the effort to take action to reduce or halt the human induced portion of climate change.

Americans are Supporting the Paris Agreement

Millions of individuals have now become activists on reducing climate change. People are changing their life styles to use less energy. They are publicly demanding that their local governments cut carbon emissions and change to less carbon based sources of energy.

The ranking United States diplomat in China, David Rank, resigned after 27 years in the State Department. He indicated that his conscious would not let him continue in light of President Trump’s withdrawal from the Paris Agreement. The governments of a number of states have publicly declared they will support the agreement. They will move ahead on measures to reduce greenhouse emissions and climate change. California, which is the sixth largest economy on the planet, is pushing ahead to become a carbon free region. Other states are following suit even if they do not officially support the Paris agreement. The number of states actively participating in cutting carbon has now reached about a dozen at the time of this writing.

Also many non-governmental environmental organizations, with millions of members, are supporting the Paris agreement. They are devoted to reducing energy use and to switch to non-carbon sources of energy. Many cities are actively working to reduce greenhouse emissions. As of June 6, approximately 250 mayors of American cities officially adopted the Paris agreement. These cities contain approximately 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 which Trump stated he represented when withdrawing from the Paris Agreement. There is no doubt that the decision of the current president of the United States has shocked  the rest of the world, let alone the majority of the people in this country. However, the people of this country will not turn their backs on the rest of the world. They will stand with all nations that are committed to reducing the extent of greenhouse gases in our atmosphere.

Climate Change and Mass Extinction

Mass extinction could happen again-do we care?

Results of our Changing Climate

Our changing climate is currently resulting in catastrophes. Island nations are being force to move or cease to exist. Inland rivers are undergoing record floods. Extreme high temperatures are doing tremendous damage to plants and animals. How great these catastrophes are in the future depends on what our nation, along with all others, do prevent climate change. Let Americans lead the way with or without our government!

Hidden Diseases in the Ice: What Could They Mean to Us?

diseases and melting ice

Diseases may surface with global warming.

By Linn Smith

“Microbial diseases are normally unable to survive for long periods outside of their hosts. But the soil under permafrost offers a unique habitat to preserve bacteria and viruses over thousands of centuries.”

—Claverie

May 30, 2017—John Piscu, a Biology professor at the Montana State University said, “You put something on the surface of ice and a million years later it may come back out.” And this is about to happen. Temperatures in the Arctic Circle are rapidly rising, three times faster than the rest of the world!

Scientist have discovered evidence of RNA which caused the Spanish flu virus in 1918. Smallpox and bubonic plague are also thought to be buried in Siberia. Is it possible these diseases could again raise their ugly heads? The answer is, unfortunately, yes! NASA scientists have successfully revived bacteria frozen in an Alaskan pond for 32,000 years.

A microbe, a term for tiny creatures that are too small to see with the naked eye, can invade our body and make us very ill. Microbes, including bacteria and fungi, can cause infectious diseases such as flu and measles. Microbes that cause diseases are called pathogens.

dormant diseases in arctic ice

Microbes in ice are resurfacing.

Survival of Microbes Within Ice

An article, “Microbes Can Survive Deep Freeze for 100,000 Years” at newscientist.com, states the theory that microbes can survive trapped inside ice crystals under 3 kilometeres (about 1.9 miles) of snow for more than 100,000 years. “A tiny film of liquid water forms around the microbe. Oxygen, hydrogen, methane and many other gases will then diffuse to this film forming air bubbles nearby and providing the microbe with sufficient food to survive, thus any microbe can remain alive in solid ice, resisting temperatures down to minus 55 degrees Celsius (-67 degrees F) and pressures of 300 atmospheres.” The microbes would not be able to grow or reproduce but would be able to repair molecular damage, keeping them intact for more than a thousand centuries. The study used ice in both the Antarctic and Greenland, detecting isolated microbes.

Disease and melting ice caps

Consequences of Global Warming

Pathogens Come Back to Life

According to an article on BBC.com by Jasmine Fox, “Not all bacteria can come back to life after being frozen in permafrost. Anthrax bacteria can do so because they form spores, which are extremely hardy and can survive frozen for longer than a century.
Other bacteria that can form spores, and so could survive in permafrost, include tetanus and Clostridium botulinum, the pathogen responsible for botulism, a rare illness that can cause paralysis and even prove fatal. Some fungi can also survive in permafrost for a long time.”

The threat of disease causing microbes resurfacing is not entirely due to melting of the ice and permafrost. An indirect result of melting ice allows for drilling of gold, minerals, oil and natural gas. The layers of permafrost containing microbes can be exposed by drilling, as opening up previously pristine areas of the arctic becomes profitable.

melting arctic and diseases

Diseases resurface with melting of Arctic.

Frozen permafrost soil, which was previously untouched by humans, is the perfect place for bacteria to remain alive for very long periods of time. Some microbes may have been embedded in the ice and frozen soil as long as a million years! That means melting ice and drilling for its natural resources could potentially open a Pandora’s box of diseases!

Microorganisms Disrupt Oceans

Even if these potential diseases would minimally affect humans, masses of microorganisms melted into the oceans will disturb the present marine systems and the balance of ocean life, flooding the oceans with long absent organisms. “Earth’s glaciers and sub-glacial sediments contain more microbial cells and carbon than all the lakes and rivers on the surface of the planet, a huge load of organic matter that, if thawed, would end up in the sea,” said Brent Christner, professor of Biological Sciences.

Release of Carbon with Thawing Biomass

The release of carbon from thawing biomass could cause an additional problem. As decaying biomass embedded in the ice is uncovered, it will convert into carbon dioxide which will add to our greenhouse gases, expediting global warming.

John Priscu, a professor studying Antarctic microbiology, states his concern for melting Arctic ice and permafrost, “If you hold that light switch right there before it flips, the lights begin to flicker. I think that’s what we’re seeing now. We’re pushing it and it’s becoming more variable, and pretty soon it’ll pass a threshold and reach a new state. Whether or not it can go back to a previous state, we don’t know. We may end up not ever being able to go back.”

We’re treading in unforeseen territory!

Global Warming is Speeding Up

Climate Change

Temperatures are steadily rising on our planet.

“May 2015 through September 2016 were the warmest 16 months on record. The year 2016 passed the previous year as the warmest year since records began.”

By Dr. John J. Hidore

May 21, 2017—Nearly three-fourths of the earth’s surface is covered by ocean and it is ocean temperatures which control global atmospheric temperatures. Approximately 90% of the energy absorbed by Earth goes into the oceans. The other 10% is absorbed by the land masses.

In the early years of keeping weather records there was very little data available concerning the world oceans. Now there is much and the data is constantly increasing. The oceans are absorbing heat energy at a faster rate now than in the past. A recent study indicates that the amount of heat energy absorbed by the oceans has doubled since 1997. The oceans are estimated to have absorbed as much energy since 1997 as in the previous years of record.

Most of the heat added to oceans is absorbed near the surface. The actual change in temperature in the ocean surface is extremely small due to the high heat capacity of water. It takes more heat energy to change the temperature of a given unit of water than to change the temperature of air or earth materials.

The amount of energy it takes to change the temperature of a given unit of water one degree Celsius will change the temperature of a unit of dry air by four degrees. The same amount of energy will change dry land by about five degrees. This helps explain why the atmosphere and bare land get so hot.

Planet Earth is warming.

Evidence of Global Warming

The majority of people, including both scientists and non-scientists around the world, understand that our planet earth is warming. There is overwhelming evidence that this is the case. Geological evidence indicates that the earth is now the warmest it has been in the last 650,000 years. Data also indicates the 20th Century was the warmest century in the past 1000 years.

The year 1880 marks the beginning of the modern historical record. Analysis of the collected data indicates the temperature on the planet has been increasing rapidly in the years since the global record was established.

The number of weather stations collecting temperature data has increased rapidly with time. There are now more than 6000 sites where data is being collected. Satellites are now also contributing data.

Global warming

Records are being broken around the world.

Global Temperatures for the 21st Century

Since 2000 global monthly temperatures have broken records more than 30 times. The average global temperature has increased about 0.8ºC (1.4ºF) since 1880. About 2/3 of this increase has been since 1975. Most of the warmest years on record have occurred since the beginning of the year 2000. It is significant, that in comparison to all the record warmth, the coldest year on record was more than one hundred years ago in 1911.

Record Temperatures Since 2000

Regions where record high mean annual temperatures occurred since the beginning of the year 2000 are:

Africa, 7 countries
Antarctica Asia, 21 countries
Europe, 23 countries
North America, 4 countries
Oceania, 2 countries
South America, 5 countries

Global Warming: 2015 to Date

The year 2015 was the warmest year on record up to that date. The mean temperature was 14.7 ºC (58.62degrees F). This was 0.9 ºC (1.62degrees F) above the mean of the 20th Century and 0.2 ºC (0.29degrees F) over 2014. It was the largest annual temperature increase on record. All months in 2015 set new records with the exception of January and April. December of 2015 was unusually warm, even for 2015. It was more than one degree Celsius warmer than the 30 year normal. Climate normals are set by 30 year intervals. The current normal is the period from 1981 to 2010.

Record Breaking Temperatures

Many global temperature records were recorded in 2015 and the trend continued into 2016. February 2016 continued a string of nearly a dozen straight months of record monthly temperatures. The winter season, December through February, was also a record.

In February 2016 global temperatures were not only record temperatures, but they rose drastically. The increase over the previous year was also the most since records began in 1880. May 2015 through September 2016 were the warmest 16 months on record. The year 2016 passed the previous year as the warmest year since records began. July of 2016 was the warmest month ever recorded since 1880.

Indian Heat Wave of 2016

India experienced extreme high temperatures in the spring of 2016. In May a severe heat wave alert was issued for several states. A severe heat wave is one in which temperatures of at least 47.2°C (117°F) occur.

In the city of Philodi, in western India, unofficial temperatures reached 51°C (124°F). This is the highest temperature on record in India. Temperatures averaged above 40°C (104 ºF) over large areas. Some urban high temperatures were:

New Delhi 47 °C (117 ºF)
Churu 50 °C (122 ºF)
Philodi 51.°C (124 ºF)

Drought in India

Indian drought causes famine.

Global Warming and Population

High temperatures in India had a huge effect on the human population. The impact on the country was immense. More than 300 million people were adversely affected. Crops failed or were below average in 13 states in during the growing season. Thousands of farmers abandoned their farms. Approximately 17,000 villages had, or were facing water shortages. Several Indian states shut down schools to reduce risk to students. Heatstroke was a widespread problem and many deaths were reported across the region. It has been classified as one of the deadliest heat waves in modern history.

The Hazards of Extreme Temperatures

It needs to be understood that temperature numbers are just a measure of atmospheric heat. What is truly important is the impact of the greater heat. Record high temperatures affect almost all living things in the region where they occur. What future temperatures will be is unknown. Since record high temperatures are occurring more and more frequently it seems highly probable that new and more frequent high temperature extremes will occur and that the effects will become more hazardous to life on the planet. The only real solution to the problem is to reduce the emissions producing the warming and curb population growth.

Record high temperatures affect almost all living things in the region where they occur!

Greenland: Human Settlement has been Dictated by a Changing Climate

Melting of the Arctic

The Arctic sea ice is melting at a record rate.

“The year 2016 was the warmest year globally since records began in 1880!

By Dr. John J Hidore

January 25, 2017—–Since Greenland was first settled by arctic people and Europeans, climate has played a huge part in the ups and downs of the human population. The first European colonization took place during a relatively warm period in the Arctic. The global climate during the years 950 AD to 1250 AD is known as the Little Climatic Optimum. Weather was unusually warm for several centuries and human settlements spread toward the Arctic. Iceland and Greenland were settled as were other islands in the North Atlantic Ocean.

Eric the Red is believed to have discovered Greenland in 982 AD. In 984 AD, the Norse founded the colony of Osterbygd on the island. Evidence of agriculture and other activities serve to indicate what the climate was like at this time. While it was a cold land, it supported enough vegetation (dwarf willow, birch, bush berries, pasture land) to make settlement possible. The settlers brought cattle and sheep that not only survived but thrived for a considerable period. The Norse established two colonies and began to farm. The outposts thrived and regular communications existed between Greenland and Iceland.

The Little Ice Age and the End of Norse Settlements

Between 1250 AD and 1450 AD climate deteriorated over wide areas around the North Atlantic in what is known as The Little Ice Age. The Little Ice Age was the coldest period in historic times. Areas bordering the North Atlantic Ocean experienced drastic cooling. Mountain glaciers expanded and in some cases reached their maximum extent since the end of the Pleistocene glaciation. Iceland’s population declined. Greenland became isolated from outside contact, with extensive drift ice preventing boats reaching the settlements. Grain that grew there in the tenth century would no longer grow. In Europe storms resulted in the formation of the Zuider Zee, and the excessively wet, damp conditions led to a high incidence of the disease, St. Anthony’s Fire (ergotism).

The little ice age marked the end of the Norse settlements in Greenland that had begun in the tenth century. After flourishing for more than 400 years the colonies disappeared about 1410 AD. A Danish archaeological expedition to the sites in 1921 found evidence that deteriorating climate must have played a role in the population’s demise. Excavations show that at first the soil permitted burying bodies at considerable depth. Later graves became progressively shallower. Some graves were in permafrost that had formed since the burial. Tree roots entangled in the coffins showed the graves were not originally in frozen ground. It also showed that the permafrost had moved progressively higher. Examination of skeletons indicated that food was becoming more and more scarce. Most remains were deformed or dwarfed. There was clear evidence of rickets. All the evidence points to a climate that grew progressively cooler, leading eventually to the isolation and extinction of the settlements. It is not certain the colonies failed due to climatic reasons, but it seems likely.

By 1516 the settlements had practically been forgotten. In 1540 a voyager reported seeing signs of the settlements, but no signs of life. The settlers had perished.

Resettlement of Greenland

There was no European settlement on the island of Greenland for 200 years. In 1721 Denmark sent an expedition to the island to form an outpost, starting the Greenland resettlement.

The Warming of Greenland

In recent centuries the climate of the Arctic basin has warmed a great deal. The average temperature over land in the Arctic for the year ending in September 2015 reached the highest since recording began in 1900. The temperature was 2.3 degrees F above the mean for the last 114 years .

The year 2016 was the warmest year globally since records began in 1880. The average temperature for 2016 was 58.69 ºF. Temperatures on Greenland followed suit. In June at Nuuk, the capitol city, the temperature reached 75º F (24º C). As temperatures continued to warm the population of the island has been growing. The current population is now above 55,000. Many small settlements have sprung up and agriculture is returning. Until recent years fishing was the primary industry, but now tourism is a growing source of income. Unemployment is relatively high, but with increasing temperatures and more varied employment sources the population is expected to continue to grow. Human settlement in Greenland has been dictated by a changing climate!
