What the Earth would look like if all the ice melted

robertscribbler The amount of methane in the Arctic hydrates alone is estimated as 400 times more than the global atmospheric CH4 burden. The question is timescale of the methane liberation: gradual, abrupt, or something in between. Satellite monitoring of methane over the Arctic Ocean is necessary. — Dr. Leonid Yerganov Depending on who you listen to, it’s the end of the world, or it isn’t. A loud and lively debate that springs up in the media every time a new sign of potential methane instability or apparent increasing emission from methane stores is reported by Arctic observational science.

India’s water crisis is already here. Climate change will compound it. Severe droughts have drained rivers, reservoirs, and aquifers across vast parts of India in recent years, pushing the nation’s leaky, polluted water systems to the brink. More than 600 million Indians face “acute water shortages,” according to a report last summer by NITI Aayog, a prominent government think tank. Seventy percent of the nation’s water supply is contaminated, causing an estimated 200,000 deaths a year. Some 21 cities could run out of groundwater as early as next year, including Bangalore and New Delhi, the report found. Forty percent of the population, or more than 500 million people, will have “no access to drinking water” by 2030. India gets more water than it needs in a given year.

Climate change might be worse than thought after scientists find major mistake in water temperature readings Global warming might be far worse than we thought, according to a new study. The research challenges the ways that researchers have worked out sea temperatures until now, meaning that they may be increasing quicker than previously suggested. The methodology widely used to understand sea temperatures in the scientific community may be based on a mistake, the new study suggests, and so our understanding of climate change might be fundamentally flawed. The new research suggests that the oceans hundreds of millions of years ago were much cooler than we thought. Climate change, battery boom threatens life on the 'roof of the world' — the Tibetan Plateau - RN Posted 19 Sep 2018, 3:58amWed 19 Sep 2018, 3:58am Climate change is sometimes discussed as a problem of the future, but on the "roof of the world", it has already arrived. The remote, icy plains of the Tibetan Plateau — the highest and largest plateau on the planet — cover a massive 25 per cent of China's landmass. It plays an important role — it contains the largest supply of fresh water outside the polar regions, and gives birth to some of Asia's most legendary rivers.

New Report Warns "High Likelihood Of Human Civilization Coming To An End" Within 30 Years A new report has warned there's an existential risk to humanity from the climate crisis within the coming decades, and a "high likelihood of human civilization coming to an end" over the next three decades unless urgent action is taken. The report, published by Australian thinktank the Breakthrough National Centre for Climate Restoration, outlines an apocalyptic scenario that could see conditions "beyond the threshold of human survivability" across much of our planet by 2050. Their analysis calculates the existential climate-related security risk to Earth through a scenario set 30 years into the future.

Future - The poisons released by melting Arctic ice In 2012, Sue Natali arrived in Duvanny Yar, Siberia, for the first time. Then a postdoctoral research fellow studying the effects of thawing permafrost due to climate change, she had seen photos of this site many times. Rapid thawing at Duvanny Yar had caused a massive ground collapse – a “mega slump” – like a giant sinkhole in the middle of the Siberian tundra. But nothing had prepared her for seeing it in person. As you walk along you see what look like logs poking out the permafrost. But they aren’t logs, they are the bones of mammoths and other Pleistocene animals – Sue Natali Climate Plan An Effective and Comprehensive Climate Plan At first glance, one might think that, given the lack of action on climate change, any regulatory action may seem welcome. Nonetheless, if we do have a say in the matter, why not advocate what we believe are the best policies?

Global warming could enlarge world’s largest dead zone - News - Nature Middle East News Published online 29 May 2019 Louise Sarant Climate modelling experts ran computer experiments to predict how the world’s largest oxygen minimum zone (OMZ), situated in the Arabian Sea, will react to future warming scenarios.1 First documented in the 1960s, the dimensions of the Arabian Sea’s dead zone, an area the size of Scotland, were only formally established a year ago by marine biologists who dispatched underwater robots.2 The most recent simulation, led by Zouhair Lachkar from New York University Abu Dhabi’s Center for Prototype Climate Modelling, showed that an additional warming of 2°C to 4°C is bound to intensify the OMZ.

Video: Al Gore’s Latest ‘Solution’ To Climate Change Is Mass Surveillance Speaking from the private jet and super yacht owners gathering, otherwise known as the COP 26 summit, Al Gore touted his latest solution to curb carbon emissions, mass surveillance via satellites, sensors and artificial intelligence. In the interview with MSNBC’s Andrea Mitchell, Gore declared that technology created by the so called Climate TRACE coalition will monitor greenhouse gas emissions and root out the culprits. “We get data consistently from 300 existing satellites, more than 11,000 ground-based, air-based, sea-based sensors, multiple internet data streams and using artificial intelligence,” Gore explained, adding “All that information is combined, visible light, infrared, all of the other information that is brought in, and we can now accurately determine where the greenhouse gas emissions are coming from.”

Climate change: Greenland lost 2 billion tons of ice this week, which is very unusual While Greenland is a big island filled with lots of ice, it is highly unusual for that much ice to be lost in the middle of June. The average "melt season" for Greenland runs from June to August, with the bulk of the melting occurring in July. To visualize how much ice that is, imagine filling the National Mall in Washington with enough ice to reach a point in the sky eight times higher than the Washington Monument (to borrow an analogy Meredith Nettles from Columbia University gave to The Washington Post). The sudden spike in melting "is unusual, but not unprecedented," according to Thomas Mote, a research scientist at the University of Georgia who studies Greenland's climate. "It is comparable to some spikes we saw in June of 2012," Mote told CNN, referring to the record-setting melt year of 2012 that saw almost the entire ice sheet experience melting for the first time in recorded history. Predictions for a record melt season

Permafrost In Canada Is Thawing 70 Years Earlier Than Expected Permafrost deep in the Canadian Arctic is undergoing a colossal thaw out – over 70 years ahead of schedule. Research published in the journal Geophysical Research Letters found that a series of unusually hot summers between 2003 and 2016 has caused the upper layers of permafrost to thaw across the Canadian High Arctic. While researchers have long anticipated that layers of permafrost in the area will thaw, their models suggested the current intensity of thawing would perhaps occur in 2090. The fact it's occurred in the first two decades of the 21st century is, therefore, very worrying. The new findings from the Permafrost Laboratory at the University of Alaska Fairbanks strongly suggest that climate change is occurring at an unprecedented rate, even faster than scientists feared. “It’s a canary in the coalmine,” added Louise Farquharson, a post-doctoral researcher and co-author of the study.
