20,000 Scientists 👨‍🔬 Have Now Signed 'Warning 🚩 to Humanity'

SNIPPET:

A chilling research paper warning about the fate of humanity has received 4,500 additional signatures and endorsements from scientists since it was first released last year.

The paper—"World Scientists' Warning to Humanity: A Second Notice"🔊—was published in November 2017 in the journal Bioscience and quickly received the largest-ever formal support by scientists for a journal article with roughly 15,000 signatories from 184 countries.

Today, the article has collected 20,000 expert endorsements and/or co-signatories, and more are encouraged to add their names.

The "Warning" became one of the most widely discussed research papers in the world. It currently ranks 6th out of 9 million papers on the Altmetric scale, which tracks attention to research.

Why I Am A 16-Year-Old Climate Activist

JAMIE MARGOLIN 🕊 🌟

MARCH 12, 2018, 12:30 PM

SNIPPET:

I am a 16-year-old climate activist. Our movement is unstoppable.

Young people have had enough. Students dominating the news cycles right now have had enough of living with gun violence. We are tired of waiting for adults to take action on the problems that are threatening our lives: The end of gun violence, racism, and climate denial are far past due. So now the young people like me are stepping up to make sure adults stop wasting precious time and start actually working to resolve these persistent challenges.

The Arctic’s convection engine is grinding to a halt, flooded by meltwater

LAST UPDATED ON MARCH 15TH, 2018 AT 6:57 PM BY ALEXANDRU MICU  E-mail author

SNIPPET:

In the frozen reaches of the North Atlantic, researchers have uncovered evidence of climate change already impacting ocean circulation. The discovery of unusual freshwater bodies at the ocean’s surface, most likely coming from melting glaciers and sea ice in Greenland or the Arctic is a worrying harbinger of larger disruptions yet to come.

But isn’t the ocean already made of water?
When you mix salt and water, the salt doesn’t just ‘melt’ in the water. It doesn’t dissolve and then its intact molecules flow alongside water molecules. Salt is an ionic mixture of a metallic atom and a non-metallic atom; in the case of table salt, those are Na, or sodium, and Cl, chlorine.

It’s ‘ionic’ because chlorine is hungry for electrons (it needs one to fill its outer layer and become stable), while sodium is partial to giving electrons (it needs to give one to strip its outer layer and become stable). So what brings and binds these two together is an electromagnetic reaction, in which sodium’s electron orbits both, making everyone kinda happier.

However, water is also electromagnetically polarized — it has a negative pole, where the oxygen atom sits, and a positive pole, where the two hydrogen atoms lay. When you mix salt with water, the Na-Cl bond breaks, the atoms (now referred to as ‘ions’) spread out through water molecules, and then satisfy their electromagnetic needs by cozying up to the ol’ H2O. If you freeze or boil the water, it separates from the salt.

In other words, salt water isn’t water with salt mixed in — it’s water that is chemically tied to the constituents of salt. Meaning it’s much denser than freshwater, so it sinks under it.

That’s why the infusion of meltwater is causing a problem in the North Atlantic: all this incoming freshwater stays at the surface of the ocean for much longer than the denser, saltwater used to do. This, in turn, could affect the natural convection processes in the area. Northbound water (which is warm, as it comes from the Equator) starts to sink as it cools and becomes denser. This body of water is then pushed below and makes its way south, goaded on by the second part of the currents that brought it to the Arctic.

This is a very real situation, but the article doesn't even mention the main feature. Excess meltwater from Greenland and melting icebergs in the Labrador Gulf can stop the Gulf Stream's natural circulation, and in theory at least, change the climate COLDER in UK and northeast Europe.  Since this is caused by global warming, it represents a negative feedback in the climate model, and is one of the reasons why climate change won't be as bad as AG proposes.  In fact there are probably other negative feedbacks in the climate system, since the planet has never suffered from runaway heating in 13 billion years.



Boy does THAT take the cake as world class BULLSHIT! The COOLING EFFECT on Europe will be MUCH MORE THAN counterbalanced by the MASSIVE HEATING on the rest of the globe. Of course, you 😈 conveniently left that out.

And, of course, this all about what "AG incorrectly believes", not about what 97% of the scientific community has irrefutably established is happening. Your fallacious debating Ad Hominem technique continues to show, Mr. Palloy fossil fueler.  

But, that wasn't the top egregiously incorrect falsehood that you spewed. Here's the one that takes the prize as the most ignorant, unscientific statement I have read in YEARS!

Palloy, that fellow that doesn't seem to know that the scientifc concensus IS that the CAUSE of the PETM and MOST of the FIVE Major extinctions was the runaway greenhouse effect, otherwise known as Runaway Heating said:
Quote
"The planet has never suffered from runaway heating for 13 billion years."


Go spread your poisonous mendacity somewhere else, Palloy. You do not understand BEANS about climate feedback loops, whether they be negative or positive. You are a walking bundle of Denier 🦖 talking points .

You are banned from this forum. Go entertain RE with your happy talk and fairy tales. I am tired of your serial lies and disingenuous baloney. Have a nice day.

Lakes on Greenland Ice Sheet Drain in Chain Reaction, Destabilizing Sheet and Raising Sea Levels

by Olivia Rosane

Mar. 15, 2018 12:22PM EST

A study published Wednesday in Nature Communications signals bad news for the Greenland ice sheet.

A research team led by the University of Cambridge found that the lakes of meltwater that form on the ice sheet in the summer drain in a chain reaction that increases the flow of the ice sheet, destabilizing it and increasing sea level rise, the University of Cambridge reported in a press release.

It had long been known that these lakes could drain quickly on an individual basis. They can last months, then drain through more than one kilometer (approximately 0.621 miles) of ice within hours.

However, this study used a combination of observation and three-dimensional modeling to show that the lakes do not drain in isolation. Instead, the melting of one lake can trigger the melting of lakes up to 80 kilometers (approximately 49.71 miles) away.

The process begins when a lake drains and the water it contained ends up on the bottom of the ice sheet. This causes the sheet to flow faster, which destabilizes it and leads to the formation of more fractures. Other lakes then drain through these new fractures in a chain reaction that can speed the flow of the ice sheet by up to 400 percent.

Researchers observed 124 lakes drain within a span of five days, and found evidence for crevices opening 135 kilometers (approximately 83.9 miles) inland from the ice sheet's edge, which is farther than thought possible.

The study therefore contradicts the findings of the Fifth Assessment Report by the Intergovernmental Panel on Climate Change, published in 2014, which held that melt water on the surface of the ice sheet did not impact its flow.

"This growing network of melt lakes, which currently extends more than 100 kilometres inland and reaches elevations as high as 2,000 metres above sea level, poses a threat for the long-term stability of the Greenland ice sheet," the study's lead author and member of Cambridge's Scott Polar Research Institute Dr. Poul Christoffersen said in the press release.

This isn't the first study in recent years to suggest the Greenland ice sheet is in more trouble than previously believed. In 2016, scientists found the ice sheet was melting 7 percent faster than they had thought.

While the Polar Portal reported that the ice sheet actually gained a small amount of mass in 2017 due to heavy winter snows and a cool summer, the National Oceanic and Atmospheric Administration calculated that the sheet could only regain the mass it has lost since 2002 after 80 years like this one.

According to Global Citizen, the ice sheet, which is seven times the size of the United Kingdom and two miles thick, is currently contributing to global sea level rise at a rate of one millimeter (approximately 0.04 inches) per year. If all the ice in the sheet were to melt, it would raise sea levels by more than 20 feet.

This is unlikely to happen any time soon, but that doesn't mean there's nothing to worry about.

"When we say the ice sheet is melting faster, no one saying it's all going to melt in next decade or the next 100 years or even the next 1,000 years but it doesn't all have to melt for more people to be in danger," Dr. Joe Cook, a glacial microbiologist at Sheffield University, told Global Citizen.

How A Handful Of Community Organizers Got NYC To Take On One Of The Most Powerful Industries 🦖 On Earth

March 17th, 2018 by Guest Contributor

Originally published on Nexus Media.

Some people start the new year by pledging to give up carbs or hit the gym. New York Mayor Bill de Blasio kicked off 2018 by declaring war on the oil industry. 🦖

In what author and activist Bill McKibben called one of the “most important moments” in the decades-long fight against climate change, the city has pledged to sell off around $5 billion in fossil fuel shares. It will also sue BP 🐉, Exxon Mobil 🦖, Chevron🦕, ConocoPhillips 🐲 and Shell for damages — namely, the gradually rising seas laying siege to New York — noting these companies deliberately misled the public about climate change.


But this isn’t a story about farsighted politicians drawing up battle plans in the basement of city hall. The call to arms didn’t come from the mayor’s office or from chambers of the City Council. It came from the streets, from the outer boroughs and from a modest network of community organizers spurred to action by one of the deadliest storms in New York history.

This is a story about people who had never had a voice sending a message that could be heard around the world.

Carolina Caycedo's "Esto No Es Agua/This is Not Water" (still), 2015 Courtesy Carolina Caycedo

Organized by assistant curator Elisabeth Sherman and curatorial assistant Margaret Kross, the exhibition focuses on the precarious state of the environment. "The idea for the show came out of talking to artists and listening to their practices," said Sherman. "We started to notice several artists working on themes that connect environmental issues with civil rights and human life."

Caycedo, for example, has created several projects that refer to the construction of hydroelectric dams in South America and the consequences for local populations. Another artist, Lena Henke, contributed sculptures that tell the story of New York City neighborhoods that were gouged from the map in the 1930s by city planner Robert Moses to make way for expressways.

This is as close to religion as I get. My ancestors have been doing this springtime bucket dance for over a century. with wood spiles and wood buckets another century and first nations people for probably thousands of years before that. I only put out 20 taps this year on the woodlot I'm trying to buy. Its very early in the season and over the last three days only about 2 litres per tap has flowed the weather has not been cooperating. if you do not get freezing temperatures at night and a sunny 5 or 6 degrees celsius during the day you get no sap.  On a good day you will get 8 litres from a good tap. This year I've moved the boiler into the greenhouse. I'm trying to add humidity to the soil and increase nighttime temperatures. On a big boil day I can actually make it rain as the condensation drips down off the plastic disturbed by a breeze. Its very peaceful and highly addictive. To see the life essence of a tree in spring boiled down to something so special is magical.
Cheers






 


I read about that Strategic Maple syrup reserve Canada has a few weeks ago. You folks DO take your Maple Syrup GOLD seriously.

Here in Vermont, Climate change is slowly destroying an important export. As you know, for the sap to run well, you need the pumping effect of above freezing temps in the day and below freezing at night. What is happening due to climate change is that the winter stays cold until it doesn't. So, we are increasingly experiencing low sap yields from lack of below freezing temperatures at night during March and April, normally the best time to harvest sap.

Enjoy your sap while you can. I don't think Canada will avoid the fate of Vermont.  :(

============

As the climate warms, the carbon balance of arctic ecosystems will respond in two opposing ways:
Plants will grow faster, leading to a carbon sink, while thawing permafrost will lead to decomposition
 and loss of soil carbon.
https://www.amap.no/documents/doc/sno...

The results presented here—that large C losses are possible from the permafrost region, whose magnitude is strongly governed by the dynamics of deeper decomposition, and that large losses are unlikely to be compensated by N fertilization accompanying decomposition—underscore the importance of considering permafrost carbon dynamics in ESMs. Permafrost soils may produce a strong, albeit delayed, C response to global change,
and must therefore be included in assessments of long-term C cycle feedbacks to climate change.

Of this there can be little doubt. The release of methane hydrates from the ocean deeps is bad enough.
There is a full more ecological catastrophe going on in the Arctic, and we remain asleep.

Arctic Ocean Ice Near Record Low for Winter, Boost for Shipping 

March 23, 2018 by Reuters

SNIPPET:

The winter retreat means ever bigger areas are ice-free year round, especially in the Barents Sea north of Russia and Norway which is becoming more like the Atlantic Ocean, he said.

The vast Shtokman natural gas field, north of Russia, is in an area that is now ice-free even in the depths of winter – helping Gazprom if it ever develops the find. The region was ice-bound in winter until the early 1980s, Eldevik said.

Shipping company Teekay said a tanker loaded a first cargo of liquefied natural gas at a terminal in Arctic Russia and traveled to France in January 2018 – the first ship to make such a winter voyage without an icebreaker.

For morons (i.e. fossil fuelers) who do not understand sea ice decline in the arctic:

AVERAGE sea ice thickness used to be around 5 to 6 meters. That was multi-year ice. NOW the multi-year ice is almost gone.

NEW ice that forms in the winter is only a little over one meter thick. THAT type of ice is becoming prevalent. THAT type of ice will allow sturdy vessels, which are NOT ice breakers, to plow through IN THE WINTER. As the article associated with the picture below CLEARLY stated, one of the new LNG carrying pigs DID cross the arctic this winter WITHOUT an ice breaker escort. The ice breaker in the picture is there in case they run into some thick ice.

However, imbeciles and other assorted MORONS may see a picture of ships in the ice, as below, and come to the incredibly IGNORANT, as well as STUPID, conclusion that there is "no lack of ice problem in the arctic 😇  ;) ".

Incredibly thin Arctic sea ice shocks researchers

Rare winter expedition near northern Norway finds weak ice that is increasingly vulnerable to storms.

Richard Monastersky 14 December 2016

SNIPPET:

Quote
Measurements made during summer expeditions have shown widespread thinning of Arctic sea ice, but researchers were not sure what the conditions were like in winter. “We saw a new Arctic where the ice is much thinner, only 3 to 4 feet thick,” says Granskog. “And this ice functions very differently than it did 10 years ago.”

That had ripple effects below the ice, says Amelie Meyer, an oceanographer at the Norwegian Polar Institute. “When storms came through, it moved the ice so fast that it actually stirred water under the ice. This helped bring warm water from below much closer to the surface and actually induced some melt of the ice from below.”

Unforgettable Sights of Our Changing World

Mar 23, 2018

The Trump 🦀 administration is pushing to eliminate NASA’s climate research programs.

These pictures show what a loss that would be.

By Jeremy Deaton

President Trump’s proposed 2019 budget would slash funding for NASA’s Earth Science Division, and while his budget hasn’t gained traction in Congress, it is an important statement of the administration’s priorities. In a nod to his allies in the fossil fuel industry, Trump is calling for the elimination of vital programs that monitor carbon pollution and climate change.

Critics say NASA’s Earth Science Division is a waste of taxpayer dollars and a distraction from the agency’s core mission of space exploration. But NASA has a critical role to play in understanding human-caused climate change, by operating satellites that monitor the Earth’s forests, deserts, oceans and atmosphere.

NASA scientists are working to improve our understanding of natural disasters like wildfires, hurricanes and drought, while tracking long-term changes to the Earth’s climate. Researchers are also mapping out those changes so Americans can understand how heat-trapping carbon pollution is reshaping the world. Below is a collection of NASA maps, graphs and photos cataloging this profound transformation.

Causes of climate change

It’s part of NASA’s mission to understand the balance of energy on Earth — how much of the Sun’s energy is absorbed by the Earth and how much of it is reflected back out to space. Over the last century, the Earth has retained more and more of the Sun’s energy, causing the planet to warm around 1 degree C.

Warming is not explained by changes in solar activity or changes in the Earth’s orbit, nor is it explained by changes in volcanic activity. What about human factors? Changes in land use — converting forests to farms and pastures — have had a slight cooling effect, as dark green woodlands are replaced by tawny-colored fields of wheat and grass, which reflect more of the Sun’s light. Ground-level ozone pollution makes the Earth a little warmer, but not much. Aerosols, another form of pollution, actually cool the atmosphere.

The evidence shows that greenhouse gasses are responsible for the warming trend. Carbon pollution is trapping more of the Sun’s heat. That carbon pollution primarily comes from burning coal, oil and gas to generate energy. It also comes from raising livestock — mostly cows and sheep — that expel methane, a powerful heat-trapping gas, and from burning forests. While converting dark-colored forests to bright-colored farmland has a small cooling effect, lighting trees on fire also releases a tremendous amount of heat-trapping carbon pollution into the sky. Trees scrub carbon dioxide from the air. When set aflame, they dump that carbon back into the atmosphere.

The line graph below shows how quickly carbon dioxide is gathering in the atmosphere, rising from 370 parts per million in 2000 to more than 400 parts per million today, as measured by the Mauna Loa Observatory in Hawaii. The map shows the changing concentration of carbon dioxide in the Earth’s atmosphere, as measured by satellite, shifting from green to yellow to orange to red as the concentration increases. Cars, trucks, factories and power plants in the United States, Europe and China are responsible for most of the pollution.

The map shows the distribution of added carbon dioxide over the same period, according to satellite data. Warmer colors indicate more carbon dioxide. Source: NASA

The world’s carbon output has grown in recent years, but there has also been a shift in where that carbon pollution is coming from. The United States, Europe and Japan have seen declining pollution thanks, in large part, to limits on pollution. In China, India in the Middle East, pollution has increased as those countries open more factories, fire up more power plants and put more cars on the road. In addition, numerous companies in the United States and Europe have moved manufacturing operations to China, effectively exporting the pollution associated with those operations.

The map below shows changes in emissions of nitrogen dioxide from 2005 to 2014. Nitrogen dioxide isn’t a heat-trapping gas like carbon dioxide, but it is a dangerous pollutant that can make it harder to breathe. Areas with little nitrogen dioxide pollution are colored in blue. Areas with more pollution are colored in yellow, while areas with the most pollution are colored in red.

The rapid growth of China looks even more dramatic when viewed up close. The satellite images below shows how Shanghai has changed between 1984 and 2016 as more companies set up factories and workers moved from rural areas to work in those factories. The population of the city roughly doubled in that time.

Industrialization isn’t the only trend driving the rise in temperature. As mentioned above, there’s also deforestation. The map below shows declining forest cover in Rondônia in western Brazil between 2000 and 2010. Settlers build roads into remote parts of the Amazon rainforest, burning forests near those roads to clear land for crops and cattle.

All together, these trends — industrialization, deforestation, growing consumption of meat — are producing dramatic changes in the Earth’s climate and, by extension, are fueling heat, drought and severe storms.

Symptoms of climate change 😓

The most obvious symptom of all that carbon pollution is a rise in the average surface temperature of the Earth. The map below is based on temperature from thousands of weather stations, ships, buoys and research outposts collected over more than a century. It shows the how much temperatures have differed from the mid-20th-century average. Blue areas are unusually cold. Orange areas are unusually hot. As the map progresses from 1880 to 2016, temperatures grow warmer across the globe.

Warming Spring 🚩
 
Published: March 7th, 2018

By Climate Central

SNIPPET:

March 1 signals the beginning of meteorological spring. In spite of the wintry precipitation that has kicked off the month in parts of the country, springs across the U.S. are getting warmer with climate change. On average, spring has warmed a little more than 2°F in the U.S. since 1970.

The strongest warming, as examined by the NCEI climate divisions, is in the Southwest. Several cities have warmed more than 5°F, including El Paso, Las Vegas, Phoenix, and Tucson. Of the 244 stations across the country we analyzed, only nine (3.7 percent) showed no warming trend at all, and more than half have warmed at least 2°F.
