We Have Been Warned: The Melting Arctic’s Dramatic Impact On Global Weather Patterns

Unprecedented floods, unending droughts, ginormous hurricanes, 70 degrees on christmas, the north pole above freezing in the middle of winter, weakening jet stream, ocean currents slowing down, the melting of polar ice sheets is quite literally affecting the rotation of the planet. The basic fact is “everything in the planet’s climate system is linked together, and when one part of it changes, all the other parts will respond.” The climate system’s responses so far are not pretty atal. Expect this climactic chaos to intensify and species extinctions to accelerate as temperatures rise and conditions worsen.” -OSJ

 

Written by Dahr Jamail @ Truthout:

Arctic sea ice is melting at a record pace – and every summer looks grimmer. This past summer saw the ice pack at its fourth-lowest level on record, and the overall trend in recent decades suggests this will only continue.

“Using satellites, scientists have found that the area of sea ice coverage each September has declined by more than 40 percent since the late 1970s, a trend that has accelerated since 2007,” according to the recent report “Arctic Matters: The Global Connection to Changes in the Arctic” by the National Research Council of the National Academies.

The report added that by the end of each of the eight summers from 2007 to 2014, Arctic sea ice extent was over less area than at any time in the preceding three decades.

In addition to rapid melting of the sea and land ice in the Arctic, temperatures there are warming at least twice as fast as those of the rest of the planet – provoking other dramatic changes.

“Eventually we should see an Arctic Ocean ice free in summers as global temperatures continue to warm.”

Massive wildfires on frozen ground, resulting from increasingly dry conditions caused by anthropogenic climate disruption (ACD), are becoming common; this phenomenon is unprecedented over at least the last 10,000 years.

These and other recent changes across the Arctic are making the weather and climate patterns there – and across the rest of the planet – more difficult to predict.

As Arctic Matters reports, “Changes in the Arctic have the potential to affect weather thousands of miles away. Because temperatures are increasing faster in the Arctic than at the tropics, the temperature gradient that drives the jet stream is becoming less intense.”

This causes the jet stream to weaken and shift away from its typical patterns, which then leads to weather patterns becoming more persistent and lasting longer in the mid-latitudes. This then results in longer droughts, more intense heat waves, and far longer and deeper cold snaps, such as those witnessed in the Northeastern United States and Europe during the last two winters.

Truthout interviewed several leading scientists on these issues, seeking a consistent expectation for what the dramatic changes in the Arctic mean. The verdict? If there’s one thing that all the scientists’ predictions have in common, it is significant change.

The Vanishing Arctic Ice Pack

Dr. Julienne Stroeve is a senior research scientist with the National Snow and Ice Data Center in Boulder, Colorado. She specializes in the remote sensing of snow and ice, and works in the Arctic measuring changes in the sea ice.

“Eventually we should see an Arctic Ocean ice free in summers as global temperatures continue to warm,” Stroeve told Truthout. She expects us to begin seeing summer periods of an ice-free Arctic ice pack around the year 2040.

Bob Henson is a meteorologist with the Weather Underground, and author of The Thinking Person’s Guide to Climate Change.

He believes that while there will most likely be some small areas of year-round ice clinging to far northern Canada for decades to come, “I would expect a summer in the next 20 to 30 years in which sea ice covers as little as 10 percent of the Arctic for at least a few days in August or September,” he said.

Everything in the planet’s climate system is linked, and when one part of it changes, all the other parts will respond.

Henson pointed out that if we extrapolate data and make predictions from more recent conditions in the Arctic, the timeline for seeing a total loss of sea ice seems faster, but he said we will most likely see summer sea ice declining “in a two-steps-forward, one-step-back process, with record ice loss in some years (as in 2007 and 2012) and a temporary, partial ‘recovery’ in other years (as in 2009 and 2013).”

Regardless of the specifics of the timeline, many agree that an ice-free Arctic will appear before the next century begins.

Dr. Steven Vavrus at the Center for Climatic Research at the University of Wisconsin-Madison focuses on the Arctic and serves on the science steering committee for the Study of Environmental Arctic Change. “The precise timing is nearly impossible to pin down, but most estimates range from around 2040 until the end of this century,” he told Truthout. “I would be very surprised if seasonally ice-free conditions during summer do not emerge by 2100.”

Dr. David Klein is the director of the climate science program at California State University, Northridge. Like others, he pointed out how the Arctic is warming two to three times faster than the rest of the planet, and pointed out how ice loss there is “proceeding more rapidly than models have predicted.”

“The loss of sea ice decreases albedo [reflectivity] and results in greater absorption of energy in the water, and the warm water then heats the air above it,” Klein told Truthout. “NASA’s CERES satellites have observed an increase of 10 watts per square meter of solar radiation absorbed by the Arctic Ocean from 2000 to 2014.”

By way of comparison, overall net planetwide warming from greenhouse gases thus far is only one-twentieth that amount of heating.

While that might not sound like very much, as James Hansen has pointed out, cumulatively that amount corresponds to 400,000 Hiroshima atom bombs per day, 365 days a year, across the planet.

Changing Global Weather Patterns

Stroeve explained why the Arctic is vitally important in terms of its impact on the global climate system.

“The Arctic is typically covered by snow and ice year around,” she said. “Snow and ice have a high albedo, meaning they reflect most of the sun’s energy back out to space, helping to keep the region, and the planet, cooler than [they] otherwise would be. As the sea ice melts, or snow [and] glaciers melt, it lowers the albedo, allowing more of the sun’s energy to be absorbed by the ocean and land surfaces, further warming the region.”

Hence, all of our large-scale weather and ocean patterns are tied to the temperature difference between the poles, which receive less solar input, Stroeve said, and the equator, which receives most of the solar input.

“If that temperature difference changes, we would expect the large-scale weather patterns, i.e. the jet stream pattern, to respond,” she added. “This would then [have an] impact on precipitation patterns, perhaps frequency of extreme weather events etc.”

Henson warned that we are entering “uncharted territory” when it comes to the loss of Arctic sea ice.

“The ice loss in recent years has been unprecedented since satellite coverage began in the 1970s, and all signals point to a continued decline in summer sea ice over the next few decades,” he said. “We may already be seeing the effects of Arctic sea ice loss in mid-latitude weather patterns.”

Henson warned that in the coming decades, an Arctic Ocean that is completely open for even a few days or weeks per year, could well shape the atmosphere “in ways that are not yet fully understood.”

“The ‘climate system’ is a complex interconnection of air, land, plants, sea and ice,” he said. “Any transformation to this system as large as the loss of summertime Arctic sea ice should concern all of us, especially since it could reverberate in yet-unknown ways.”

Vavrus explained how the Arctic is the “refrigerator” of the global climate system, acting as the cold region that balances out the hot tropics.

“In this role, the Arctic helps to regulate the energy balance of the climate system and the weather circulation patterns both within high latitudes and elsewhere,” he said.

He went on to point out that the most common expectation among scientists about the impact that the loss of summer sea ice will have on global climate patterns is that more solar energy will be absorbed by the Arctic Ocean and land, and the added heat from the earth’s surface will then be released back into the atmosphere during autumn and winter.

“That will then make the region much warmer during those seasons than in the current climate,” Vavrus said. “That will likely lead to a weakening of jet-stream winds and probably a wavier jet-stream flow pattern.”

This will then result in shifting jet-stream winds, and lead to more persistent and extreme weather patterns both within and outside of the Arctic, he added.

Extreme weather patterns don’t necessarily mean a universal trend toward hot weather. Henson pointed out that research by some scientists is showing that sea ice loss may be helping to cause colder mid-latitude winters like those seen recently in the Northeastern United States. Why? According to Henson, this could be because “the heat released from the newly opened ocean may be helping to slow and weaken the polar jet stream.”

Another mechanism Henson mentioned is how open water in the Barents and Kara Seas may be moistening the autumn atmosphere over Siberia, leading to heavier autumn snows and triggering a chain of events leading to midwinter Arctic outbreaks.

Stroeve said that while exact ramifications of an ice-free Arctic continue to remain unclear, “There is some thought that the warming Arctic has already led to a slowing down of the zonal wind speeds, and perhaps also causing a wavier jet-stream pattern, which would allow for more extreme (or ‘stuck’) weather patterns to persist.”

Klein pointed to how the melting Arctic sea ice “can disrupt normal ocean circulation because of the influx of freshwater from the melted ice, and rising air heated by the water can change wind patterns and even perturb the jet stream, which in turn might alter weather patterns thousands of miles away.”

Some current research states that this contributes to the extreme “polar vortex” weather events we’ve seen in recent years, in addition to the extreme drought plaguing much of the western United States.

Klein also pointed out another dramatic impact the loss of ice is having within the Arctic itself.

“With ice no longer stabilizing land along coasts, erosion will increase and fragile permafrost areas will release more greenhouse gases,” he said. “Permafrost coasts [permanently frozen soil next to open water bodies] comprise a third of the world’s coastline. This is another positive feedback leading to further warming.”

We Have Been Warned

Stroeve pointed out that people should be concerned about the upcoming summer periods of an ice-free Arctic Ocean due to the fact that everything in the planet’s climate system is linked together, and when one part of it changes, all the other parts will respond.

“It also causes our planet to warm further, changes [in] species’ habitat/range, perhaps leading to extinction for some species,” she explained. “A change in our precipitation patterns will impact food and water security. Then, of course, there are people who live in the Arctic and are being directly impacted by these changes.”

Dr. Jennifer Francis, a research professor at Rutgers University’s Department of Marine and Coastal Sciences whose research is focused on the Arctic, pointed out how the Arctic sea ice plays a critical role in the region’s climate system and marine ecosystem. And as we’re learning, its disappearance “is having broad effects well beyond the Arctic.”

Impacts range “from weather patterns to animal migrations to ocean current systems to food webs,” Francis told Truthout. “Its loss will be felt directly and indirectly by billions of people.”

 

Study – Earth’s Battery Level Critical: Continued Destruction Of Earth’s Biomass Foretells Grim Future For Life On Earth

In Uncategorized on August 28, 2015 at 6:29 pm

Fig. 1. Earth-space battery.The planet is a positive charge of stored organic chemical energy (cathode) in the form of biomass and fossil fuels. As this energy is dissipated by humans, it eventually radiates as heat toward the chemical equilibrium of deep space (anode). The battery is rapidly discharging without replenishment.

Oldspeak: I’ll let the scientists tell it:

Earth is a chemical battery where, over evolutionary time with a trickle-charge of photosynthesis using solar energy, billions of tons of living biomass were stored in forests and other ecosystems and in vast reserves of fossil fuels. In just the last few hundred years, humans extracted exploitable energy from these living and fossilized biomass fuels to build the modern industrial-technological-informational economy, to grow our population to more than 7 billion, and to transform the biogeochemical cycles and biodiversity of the earth. This rapid discharge of the earth’s store of organic energy fuels the human domination of the biosphere, including conversion of natural habitats to agricultural fields and the resulting loss of native species, emission of carbon dioxide and the resulting climate and sea level change, and use of supplemental nuclear, hydro, wind, and solar energy sources. The laws of thermodynamics governing the trickle-charge and rapid discharge of the earth’s battery are universal and absolute; the earth is only temporarily poised a quantifiable distance from the thermodynamic equilibrium of outer space.

Although this distance from equilibrium is comprised of all energy types, most critical for humans is the store of living biomass. With the rapid depletion of this chemical energy, the earth is shifting back toward the inhospitable equilibrium of outer space with fundamental ramifications for the biosphere and humanity. Because there is no substitute or replacement energy for living biomass, the remaining distance from equilibrium that will be required to support human life is unknown.
Eventually, without sufficient living biomass to run the biosphere, it simply doesn’t matter how much oil, solar, nuclear, etc. energy you have, as there is no biosphere left for humans to use it. Biomass is not an interchangeable energy. There is no replacement and we are depleting it rapidly.
As we burn organic chemical energy, we generate work to grow our population and economy. In the process the high-quality chemical energy is transformed into heat and lost from the planet by radiation into outer space. The flow of energy from cathode to anode is moving the planet rapidly and irrevocably closer to the sterile chemical equilibrium of space.
Unless biomass stores stabilize, human civilization is unsustainable.
The Earth is in serious energetic imbalance due to human energy use. This imbalance defines our most dominant conflict with nature. It really is a conflict in the sense that the current energy imbalance, a crisis unprecedented in Earth history, is a direct consequence of technological innovation.
Ironically, powerful political and market forces, rather than acting to conserve the remaining charge in the battery, actually push in the opposite direction because the pervasive efforts to increase economic growth will require increased energy consumption.”
Dr. John R. Schramski et al. June 2015
the earth is shifting back toward the inhospitable equilibrium of outer space with fundamental ramifications for the biosphere and humanity.” You can say that again. Not a “doomer”, not a “Nihilist” that said that, but a good old fashioned, dyed in the wool and presumably conservative, scientist. As I’ve been saying for some time now. It’s just physics at this point. And the physics are SHITTY for probability of continued survival of humans and most other forms of complex life on Earth. As has been discussed here, humans are using ever increasingly unsustainable quantities of biomass. With no tenable plans for population control in place or even being discussed (every one has a right to babies dammit!), or sufficiently sustainable limits to biomass consumption,  We can expect human population to increase in relation to depletion of biomass. Unfortunately for us, biomass is not infinite at current and future levels of consumption. We have used HALF the amount of biomass that it took billions of years to accumulate: 1,000 billion tons of carbon in living biomass; in the last 2000 years. 10 percent of it in the last 100 years.  So energy consumption and energy depletion is increasing exponentially. This is unsustainable. Our technology and cleverness will not make everything ok this time. Our actions will likely make things worse. Yet we’re being driven maniacally, ceaselessly, to “do more”, to “fight climate change”, not understanding that every time we do something, we’re merely increasing our increasingly unsustainable and irreplaceable earth battery usage. And carbon footprint. Nothing we “do” can be done without plunging us further into ecological debt and destruction. That is what you call a conundrum Kimosabe. The technology many magical thinkers are trusting to “fix it”, requires tremendous amounts of resources and energy to produce and maintain. Resources and energy that are rapidly and unsustainably being depleted.  In this stage of this mass extinction event, our “actions” serve only to hasten our extinction. Marches won’t stop it. Policy changes wont stop it. Geo-engineering won’t stop it. Hopium won’t stop it. We’re simply too far gone now. Can’t shift into reverse. One of the studies author’s said it best: “I call myself a realistic optimist, I’ve gone through these numbers countless times looking for some kind of mitigating factor that suggests we’re wrong, but I haven’t found it.” Eventually Earth, the sacred battery upon which we depend inextricably for energy and life, will go dead. At some point shortly after that,  we and most life on Earth will go extinct, and at some point in the distant future, the microbes inherit the Earth. And SCENE. Show’s over folk. Humans will be added to the geologic history pile of  species that used to be here. It happens all the time. It’s the circle of life. Some times on, some times off. Read the actual Study if you can.  Good stuff in there.” -OSJ

Written By James Hataway @ University Of Georgia:

Unless humans slow the destruction of Earth’s declining supply of plant life, civilization like it is now may become completely unsustainable, according to a paper published recently by University of Georgia researchers in the Proceedings of the National Academy of Sciences.

“You can think of the Earth like a battery that has been charged very slowly over billions of years,” said the study’s lead author, John Schramski, an associate professor in UGA’s College of Engineering. “The sun’s energy is stored in plants and fossil fuels, but humans are draining energy much faster than it can be replenished.”

Earth was once a barren landscape devoid of life, he explained, and it was only after billions of years that simple organisms evolved the ability to transform the sun’s light into energy. This eventually led to an explosion of plant and animal life that bathed the planet with lush forests and extraordinarily diverse ecosystems.

The study’s calculations are grounded in the fundamental principles of thermodynamics, a branch of physics concerned with the relationship between heat and mechanical energy. Chemical energy is stored in plants, or biomass, which is used for food and fuel, but which is also destroyed to make room for agriculture and expanding cities.

Scientists estimate that the Earth contained approximately 1,000 billion tons of carbon in living biomass 2,000 years ago. Since that time, humans have reduced that amount by almost half. It is estimated that just over 10 percent of that biomass was destroyed in just the last century.

“If we don’t reverse this trend, we’ll eventually reach a point where the biomass battery discharges to a level at which Earth can no longer sustain us,” Schramski said.

Working with James H. Brown from the University of New Mexico, Schramski and UGA’s David Gattie, an associate professor in the College of Engineering, show that the vast majority of losses come from deforestation, hastened by the advent of large-scale mechanized farming and the need to feed a rapidly growing population. As more biomass is destroyed, the planet has less stored energy, which it needs to maintain Earth’s complex food webs and biogeochemical balances.

“As the planet becomes less hospitable and more people depend on fewer available energy options, their standard of living and very survival will become increasingly vulnerable to fluctuations, such as droughts, disease epidemics and social unrest,” Schramski said.

If human beings do not go extinct, and biomass drops below sustainable thresholds, the population will decline drastically, and people will be forced to return to life as hunter-gatherers or simple horticulturalists, according to the paper.

“I’m not an ardent environmentalist; my training and my scientific work are rooted in thermodynamics,” Schramski said. “These laws are absolute and incontrovertible; we have a limited amount of biomass energy available on the planet, and once it’s exhausted, there is absolutely nothing to replace it.”

Schramski and his collaborators are hopeful that recognition of the importance of biomass, elimination of its destruction and increased reliance on renewable energy will slow the steady march toward an uncertain future, but the measures required to stop that progression may have to be drastic.

“I call myself a realistic optimist,” Schramski said. “I’ve gone through these numbers countless times looking for some kind of mitigating factor that suggests we’re wrong, but I haven’t found it.”

Oldspeak: “Earth Provides enough to satisfy every mans needs, but not every man’s greed.” -M. Gandhi.

“So, Yeah. That’s happening. Half of the world’s oxygen supply is quite probably GONE.  At some point in the not too distant future, air-breathing life on Earth will have half as much of it to inhale. Every day of business as usual, brings that point ever closer. Faster. Oh and Earth’s temperature is hot as Hades,  rainforests are burning, permafrost is rapidly melting, droughts are intensifying, freshwater is swiftly depleting (the San Joaquin Valley is sinking 2 inches A MONTH as a result of prolonged drought & unsustainable aquifer depletion and agricultural practice) seas are rising,  extinctions are accelerating, with pink salmon and polar bears on their way out, enjoy your romaine lettuce while you can;  you know, the ‘New Normal’.  Meanwhile Most Humans however, estranged as we are from our life-sustaining ecology are partying like it’s 1999. Destroying, extracting, heating, contaminating, consuming, emitting, polluting at the “Old Normal” pace. Behold! Human industrial civilization, the ultimate non-linear positive feedback loop! The end of the article was quite gallows humorous to me. A glaciologist, who has witnessed over an extended period the carnage being wrought in polar regions, knowing that we are on track for 4-5 degrees C of warming in the near to midterm future,  presumably knowing that ”on a planet 4 degrees C warmer all we can plan for is extinction“, spoke this fantastical absurdity: “In Denmark, we have the resilience, so I’m not that worried about my daughter’s livelihood going forward. But that doesn’t stop me from strategizing about how to safeguard her future – I’ve been looking at property in Greenland. As a possible bug-out scenario.” -Dr. Jason Box.

We know things are a bit “off” when a rainforest is on fire.

Over 400 acres of the Queets Rainforest, located in Olympic National Park in Washington State, nearby where I live, have burned recently, and it is continuing to burn as I type this. Fires in these rainforests have historically been rare, as the area typically receives in excess of 200 inches of rain annually.

But this is all changing now.

The new normal is that there is no longer any “normal.”

The new normal regarding climate disruption is that, for the planet, today is better than tomorrow.

To see more stories like this, visit “Planet or Profit?”

Another perfect example of this is a crucial recent study led by James Hansen, the former director of NASA’s Goddard Institute for Space Studies. The study, authored by Hansen and more than a dozen other scientists and published online, warns that even staying within the internationally agreed goal of keeping the planet within the 2-degree Celsius temperature warming limit has already caused unstoppable melting in the Antarctic and Greenland ice sheets. The study shows that this will raise global sea levels by as much as 10 feet by the year 2050, inundating numerous major coastal cities with seawater.

The oceans and all marine life will be “irreversibly changed” unless there are immediate and dramatic cuts in carbon dioxide emissions.

As if that’s not enough, Hansen’s study comes on the heels of another study published in Science, which shows that global sea levels could rise by at least 20 feet, even if governments manage to keep global temperature increases to within the agreed upon “safe” limit of 2 degrees Celsius. The study warns that it is quite possible that 75 feet of sea level rise could well already be unstoppable given current carbon dioxide levels in the atmosphere and recent studies that show how rapidly Greenland and several Antarctic ice sheets are melting.

Disconcertingly, another new “normal” this month comes in the form of huge plumes of wildfire smoke over the Arctic. At the time of this writing, well over 12 million acres of forest and tundra in Canada and Alaska have burned in wildfires, and the smoke covering the Arctic sea ice is yet another anthropogenic climate disruption (ACD) amplifying feedback loop that will accelerate melting there. The additional smoke further warms the atmosphere that quickens the melting of the Arctic ice pack.

As if that’s not enough to keep you up at night, a recently published study by a team from Anglia Ruskin University’s Global Sustainability Institute has shown that society will likely collapse within 30 years, due to catastrophic food shortages resulting from the ever-worsening impacts of ACD.

“The results show that based on plausible climate trends, and a total failure to change course, the global food supply system would face catastrophic losses, and an unprecedented epidemic of food riots,” the Institute’s director, Dr. Aled Jones, told Insurge Intelligence. “In this scenario, global society essentially collapses as food production falls permanently short of consumption.”

Another shocking study, this one published in The Anthropocene Review, shows how humans are causing catastrophic shifts in planetary ecosystems that have been unprecedented for 500 million years. The study outlines how human actions have led to extinctions of plants and animals, and added that while “species extinctions and other changes are far more advanced” already, “[g]lobal warming as a phenomenon is just beginning.”

Bad news from scientific studies flowed abundantly this last month when it comes to the oceans, as well.

Another major report, this one published in Science, warns that the oceans and all marine life will be “irreversibly changed” unless there are immediate and dramatic cuts in carbon dioxide emissions – a scenario from the realm of fantasy, given the current political climate. The report states clearly that even the 2-degree Celsius “maximum allowable temperature” rise from ACD agreed upon by world governments “will not prevent dramatic impacts on global ocean systems.”

As if all this isn’t enough to impress upon you how rapidly ACD is progressing, 2014 was also confirmed as the hottest year ever recorded, both on land and in the oceans. That report was followed by another from the National Oceanic and Atmospheric Administration that showed that the first half of 2015 was, by far, the hottest ever recorded on the planet.

As this dispatch dives into greater detail about how the world is being changed dramatically, buckle up. The news does not get any easier to take in.

Earth

The impacts from ACD continue to take dramatic tolls on the earth’s species.

Researchers recently reported that warmer temperatures across both North America and Europe are leading to loss of habitat for bumblebees, which in turn is threatening their very survival.

In the UK, several species of birds are now under threat because temperature shifts are pushing several of the species further north, even all the way to Scandinavia. Once there, the birds encounter habitat they are not adapted to, and likely won’t survive.

Scientists in the United States with the US Geological Survey released a report that shows that polar bears will have a steep decline in their populations in most places in the Arctic as the sea ice melts away. This isn’t news, but the report shows how closely scientists are monitoring the situation, due to the speed at which the melting of the polar ice cap is occurring.

Humans are not immune to the growing impacts of ACD.

Another study published in Science shows that polar bears’ metabolism will not be able to adapt quickly enough to their dramatically changing habitat as the Arctic warms and melts. This, coupled with a dramatic decline in their sources of food, again confirmed that the iconic bears are most likely en route to extinction.

Of course, humans are not immune to the growing impacts of ACD.

A report produced by the University College of London’s commission on health and climate change along with the Lancet revealed that ACD threatens to erode five decades of overall progress in global human health.

Professor Anthony Costello, director of the UCL Institute of Global Health and co-chair of the commission, told the Guardian that on our current trajectory of warming, we are going to see “very serious and potentially catastrophic effects for human health and human survival.

“We see that as a medical emergency because the action we need to do to stop that in its tracks and get us back onto a 2C trajectory or less requires action now – and action in the next 10 years – otherwise the game could be over,” he added.

For the earth itself, ACD is even leading to geo-structural changes.

In Greenland, massive earthquakes are resulting from melting glaciers, and icebergs calving from tidal glaciers collapsing into the ocean are causing consistent quakes of magnitude 4-5.2, with most of them closer to 5, according to a recent study published in Science. The calving glaciers are also causing tsunamis.

Water

As usual, the impacts of ACD are most dramatic on the waterfront.

A recent report revealed that all of the world’s sea turtles are at risk, due to rising sea levels. Higher sea levels mean their rookery sites, where their babies hatch, are becoming submerged.

Equally distressing, the entire pink salmon population in the Pacific Ocean is at risk, as they are being subjected to a double impact: the acidification of their ocean habitats, coupled with the acidification of rivers, slowing their growth and killing them off there as well.

Speaking of salmon, in Oregon, salmon must be trucked north hundreds of miles to a hatchery in Washington State, in a desperate effort to save fish that have been dying off in the tens of thousands due to increasingly warming river waters.

We know there is trouble when we are having to truck fish north in an effort to keep them alive; needless to say, this is not a sustainable activity.

A group of scientists from the Marine Conservation Institute recently announced that deep-sea coral reefs off the coast of Australia could be dead within 50 years due to warming temperatures and ocean acidification.

A series of recent studies has recently confirmed that ACD’s impacts on the oceans, including warming temperatures and acidification of the waters, is causing global seafood supplies to diminish drastically.

Plankton, the basis of the entire food chain, are threatened by ocean acidification.

More bad news for the planets’ oceans comes from a recent study that shows that plankton, the basis of the entire food chain, are threatened by ocean acidification. Some species of plankton will die out, while others will flourish, creating an imbalance that the report’s authors say will be “a big problem,” given that plankton produce half the total oxygen supply for the planet.

Pause for a moment before reading further and ponder the implications of that: The source of half the world’s oxygen is in major peril.

Droughts around the planet continue to abound.

Chile is facing its driest year to date, since record keeping began. There has been little to no snow on any of its famous ski slopes, and the lack of rainfall has worsened the already bad pollution problem in the country’s capital city.

In Canada, several counties in the province of Alberta announced in July that they were seriously considering declaring themselves in a state of agricultural disaster due to severe drought. It’s one of the worst drought’s in Alberta’s history, and one farmer said, “It’s almost get¬ting at the point rain wouldn’t help much.”

In addition to the important report on sea level rise mentioned at the beginning of this article, the Guardian recently posted a video that investigates the question of whether Filipinos will have to abandon Manila due to rising sea levels. Manila has a population of roughly 2 million people.

Needless to say, glaciers and ice sheets around the world continue to melt at breakneck speeds.

The impacts of warmer ocean temperatures “will be felt for centuries to come.”

NASA recently released a report showing that in Turkey, more than half of the ice cover in the mountainous regions has vanished since the 1970s. A map in the NASA report shows five areas in Turkey’s mountains where 100 percent of the glaciers have disappeared, and three areas where 75 percent of them are gone.

Another study released in July revealed another factor that is causing the Arctic to melt at a pace far faster than believed possible: Warm, tropical air masses are speeding up Greenland’s melting by warming Arctic air, as well as causing warmer rains to fall over the ice sheets.

Another NASA study found that the melting of Alaskan glaciers is now estimated to be one of the current largest contributors to global sea level increases. Maps in the study show dramatic changes to Alaska’s glaciers between 1994 and 2013, revealing a precipitous decline in their total mass. NASA estimates that the region lost approximately 75 billion tons of ice per year over that 19-year period, which is equivalent to around 30 percent of the amount of ice lost each year from the Greenland ice sheet.

Lastly, climate scientists affiliated with the US government announced recently that the warming of the oceans due to ACD is now unstoppable, and will continue to bring additional sea level rise, acidification and increasing global temperatures. Their report added that the impacts of the warmer ocean temperatures “will be felt for centuries to come” – even if immediate efforts are made to cut global carbon dioxide emissions.

Fire

In Canada, wildfires that have been described as “unprecedented” have forced more than 13,000 residents of Saskatchewan from their homes (a record evacuation), with wildfire-driven evacuations happening across other provinces as well.

The town of Whistler, Canada, famous for its world-class ski resort, is dealing with horrible air quality as smoke from wildfires is polluting the air across British Columbia.

NASA recently released disturbing images of smoke from the Alaskan and Canadian wildfires that is blowing out over the Greenland Sea.

Wildfires are ravaging parts of Southern California where the megadrought is cutting deep. The fire season started earlier than “normal” this year, and was helped along by massive numbers of dead trees brought to their demise by the increasing bark beetle infestation. That infestation was fueled by warmer temperatures as well as the drought itself. Hence several runaway feedback loops are feeding off one another.

A recently released study shows, again, how ACD has caused wildfire seasons around the globe to begin earlier and last later, shifting what “normal” means in the realm of fire.

Air

Heat records on three continents fell this last month, as brutally hot conditions in early July baked parts of Europe, Asia and South America. Dozens of heat records were broken: Maastricht, the Netherlands, saw 100.8 degrees Fahrenheit, an all-time July heat record for that nation, along with several other heat records throughout the country. London’s Heathrow Airport saw 98.1 degrees Fahrenheit, an all-time heat record for the UK.

In Thailand, Kamalasai saw 105.8 degrees, the hottest temperature ever recorded for that country, while other heat records across the nation were set as well. In Pakistan, morgues literally ran out of space as a heat wave there killed more than 1,000 people.

In South America, Urumita, Colombia, reached 108 degrees Fahrenheit, setting an all-time high for that country.

Heat records across the United States continue to be broken as well, including in Seattle, which has seen several record temperatures this summer, with possibly more to come.

A recent study has linked Hurricane Sandy and other extreme weather events around the globe to ACD. The study, published in Nature Climate Change, shows how ACD is ramping up extreme weather events, both in frequency and intensity, to never-before-seen levels.

Denial and Reality

Regarding ACD, news on the denial front never runs dry.

It emerged recently that Exxon was aware of ACD as far back as 1981, but continued to deliberately fund climate change deniers nonetheless … and has gone on to spend millions of dollars since then to continue to do so, to this day.

The US House of Representatives, in another stroke of genius, passed a bill that allows state governors to refuse to comply with the Environmental Protection Agency’s Clean Power Plan, developed to lower carbon dioxide emissions from currently active power plants.

Elected politicians acting on behalf of Big Oil and Gas are functioning as little more than lobbyists for said industries, despite what’s at stake (the planet and human existence).

On the reality front, to counter these amazing acts of denial, Pope Francis continues to fight the good fight as far as ACD goes. Thousands of religious leaders recently marched in Rome in support of his call to world leaders to take a stand and work to mitigate the impacts of ACD.

On that note, more than a dozen Catholic organizations have launched a campaign that is asking Catholics around the world to change their lives in order to reduce their carbon dioxide emissions and lower their consumption.

A recent study has shown, again, that ACD has made deadly floods and record heat waves over the last month even worse, and will continue to make other extreme weather events more intense, as well as more frequent.

“We need the deniers to get out of the way. They are risking everyone’s future.”

Lastly, an excellent article in Esquire about Dr. Jason Box provides a glimpse into the dilemma climate scientists face in regards to the intensely troubling information their research is producing and the emotions elicited by it, coupled with the pressures they face politically. Box, a world-renowned glaciologist whose focus is the Greenland ice sheet, has not been shy about expressing his opinions, and sometimes emotions, about what he is seeing.

Box has said things like: “If even a small fraction of Arctic sea floor carbon is released to the atmosphere, we’re fucked,” and concluded that a 70-foot rise in sea levels over the next few centuries was probably already “baked into the system.” After these and other similar statements, he has come under intense fire from both the scientific community and – of course – the deniers.

Box, a US citizen, had already taken his family and moved to Denmark, where he works while continuing his cutting-edge studies on the Greenland ice sheet, largely due to the ongoing attacks he withstood from the oil-and-gas-funded deniers in the United States.

“We need the deniers to get out of the way. They are risking everyone’s future,” Box told Esquire. “The Koch brothers are criminals…. They should be charged with criminal activity because they’re putting the profits of their business ahead of the livelihoods of millions of people, and even life on earth.”

Box thinks there is at least a 50 percent probability that the world is already on track to go well over the 2-degree Celsius politically accepted maximum limit of global warming, and agrees with most climate scientists that we are on a trajectory toward more like 4-5-degree Celsius warming in the near to mid-term future.

When asked what amount of warming would throw Greenland into irreversible ice loss, Box answered “between two and three degrees.”

When Greenland goes, that is enough sea level rise to destroy every coastal city on the planet. Speaking of Antarctica, Box said: “Abrupt sea level rise is upon us.”

“The forests are dying, and they will not return,” he told Esquire about his home state of Colorado. “The trees won’t return to a warming climate. We’re going to see megafires even more, that’ll be the new one – megafires until those forests are cleared.”

Meanwhile, he has adjusted his life to minimize his carbon footprint, and continues his work in Greenland, but is worried about his daughter’s future. Box’s view of the disrupted climactic future is scary enough; he is thinking about survival.

“In Denmark, we have the resilience, so I’m not that worried about my daughter’s livelihood going forward,” he said. “But that doesn’t stop me from strategizing about how to safeguard her future – I’ve been looking at property in Greenland. As a possible bug-out scenario.”
