Antarctic Volcanoes Waking up?

Nearly 100 Volcanoes Discovered Beneath Antarctica’s Ice http://blogs.discovermagazine.com/d-brief/2017/08/14/volcanoes-under-antarctica A new volcanic province: an inventory of subglacial volcanoes in West Antarctica http://www.geos.ed.ac.uk/homes/rbingha2/48_2017_Vries.pdf Scientists discover 91 volcanoes below Antarctic ice sheet This is in addition to 47 already known about and eruption would melt more ice in region affected by climate change https://www.theguardian.com/world/2017/aug/12/scientists-discover-91-volcanos-antarctica How a melting ice…

Vanishing Arctic Ice and Amplification

While heat waves and more intense storms have been directly linked to a warming Earth, new research is exploring possible impacts of an Arctic that is warming at twice the pace of the rise in global temperatures. Jennifer Francis, Rutgers University, discusses new research and efforts to understand this controversial aspect of climate change in…

Drew Shindell: Climate Policy to Avoid Tipping Points

Head of the SAP, Drew Shindell, talks about why a near-term climate goal is important, the main message the article aims to convey, why governments should adopt a near-term goal, and whether reducing near-term warming can prevent climate tipping points. The Climate and Clean Air Coalition’s Scientific Advisory Panel (SAP) published an article in Science…

Like Champagne opened, methane explosions resulted in Ocean craters

Like ‘champagne bottles being opened’: Scientists document an ancient Arctic methane explosion What could possibly go wrong, ignoring climate change, the warnings or clues from what science tells us, even if we were just creating a better world with clean energy, and millions of new jobs? One thing which could go very wrong, are based…

Climate Change in the Arctic and Model Projections

This video with scope on permafrost melting, highlights some of the new developments of our understandings, of what happens in the Arctic due to global warming. The Woods Hole Research Center (WHRC), at the University of Alaska Fairbanks May 11, 2017. Professor of Geophysics Vladimir Romanovsky discusses the impact of Arctic permafrost thaw.

Cleaner Air, The Ocean, and Global Warming

Reductions in sulfur dioxide (SO2) emissions in recent years, for cleaner air, mainly in South East Asia due to a severe manufacturing sector slowdown and pollution policy changes (1,2) may attribute to current warming, since the phenomena called global dimming is involved. The first policies to address air pollution in the 20th century, originated after…

NASA/NSIDC: 2016 Arctic sea ice wintertime extent hits another record low

  2016 Arctic sea ice wintertime extent hits another record low By Maria-Jose Viñas, NASA’s Earth Science News Team Excerpt Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.…

Ice sheets may be hiding vast reservoirs of methane

The study indicates that under the frigid weight of Barents Sea Ice sheet, which covered northern Eurasia some 22 000 years ago, significant amounts of methane may have been stored as hydrates in the ground. As the ice sheet retreated, the methane rich hydrates melted, releasing the climate gas into the ocean and atmosphere for…

AGU 2015: Alaska’s thawing permafrost Latest results and future projections

Alaska’s permafrost is starting to thaw as the climate warms, and scientists project there will be even greater thawing of the frozen soils in the coming decades, releasing carbon into the atmosphere, and impacting ecological systems and infrastructure. A panel of permafrost experts will unveil new findings about permafrost degradation in Alaska, where permafrost covers…

Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…

Fossil Fuel Emissions could Eliminate the Antarctic Ice sheet entirely, causing about 58 m Sea Level Rise

A new open access study in Science Advances concludes that a warming beyond the 2°C target would potentially lead to rates of sea-level rise dominated by ice loss from Antarctica, and continued CO2 emissions from fossil sources could cause additional tens of meters of sea level rise, over the next millennia and eventually ultimately eliminate the…

Sudden ice loss acceleration at the Southern Antarctic Peninsula detected

ESA posted an update on Antarctic ice loss on 22 May 2015. Above animation shows how warm ocean water penetrates the glacier grounding line through basalt melt, threatening speed up of glaciers, discharged into the ocean. A recent acceleration in ice loss in a previously stable region of Antarctica has been detected by ESA’s ice mission. The…
