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.…

Ted Scambos on new Antarctic Ice Study insights

Ted Scambos, Lead Scientist at the National Snow and Ice Data Center, weighs in on the latest study showing increased vulnerability of the Antarctic ice sheet to collapse. Is it possible that the most recent study of ice instability in Antarctica is cracking the unstable cliff face of climate denial? (how’s that for a tortured…

Sea level rise estimates doubled

Brady Dennis and Chris Mooney from The Washington post, recently reported on updated sea level rise projections. Sea levels could rise nearly twice as much as previously predicted by the end of this century if carbon dioxide emissions continue unabated, an outcome that could devastate coastal communities around the globe, according to new research published Wednesday. The main reason? Antarctica. Scientists…

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…

A potential future world scenario, driven by rapid regional changes

As someone who follows the climate topic for several years, I’ve to conclude that we are still far away from taking climate change seriously. Around 10 years ago there were rather minor groups of concerned scientists and bloggers, while the media was giving “a balanced view” to the so called deniersphere. This went on for…

AGU 2015: Eric Rignot – Ice Sheet Systems and Sea Level Change

Scientific Discipline Cryosphere Speaker Eric Rignot (NASA Jet Propulsion Laboratory) Abstract Modern views of ice sheets provided by satellites, airborne surveys, in situ data and paleoclimate records while transformative of glaciology have not fundamentally changed concerns about ice sheet stability and collapse that emerged in the 1970’s. Motivated by the desire to learn more about…

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…

NASA: Zachariæ Isstrøm Glacier Greenland entered accellerated retreat

NASA: Zachariæ Isstrøm has become the latest Greenland glacier to undergo rapid changes in a warming world. Research published November 2015 in Science found that Zachariæ Isstrøm broke loose from a stable position in 2012 and entered a phase of accelerated retreat. The consequences will be felt for decades to come. The reason? Zachariæ Isstrøm is…

Why 2°C Global Warming is Highly Dangerous

Recently, James Hansen the former director of NASA GISS published new study findings about future sea level rise, ice melt, and temperature changes, as well as the possible implications for future climate. Above video highlights a part of a talk Hansen held on December 1, 2015 at the Paris climate change conference (COP21). The take…

Arctic Sea Ice Reaches 2015 Minimum Extent

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on Record According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado…

NASA State of Sea Level Rise Science 2015 – 30 feet of SLR possible by 2100

Excerpt from https://www.youtube.com/watch?v=vDdNxb2xVBU Members of NASA’s new interdisciplinary Sea Level Change Team discussed recent findings and new agency research efforts during a media teleconference Aug. 26, 2015, at 12:30 p.m. EDT. The panelists for this briefing were: — Michael Freilich, director of NASA’s Earth Science Division at the agency’s headquarters in Washington — Steve Nerem,…

NASA Rising Seas: The State of the Greenland Ice Sheet (2015)

Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…

The Hidden Meltdown of Greenland!

Aug. 28, 2015: More than 90 percent of our planet’s freshwater ice is bound in the massive ice sheets and glaciers of the Antarctic and Greenland. As temperatures around the world slowly climb, melt waters from these vast stores of ice add to rising sea levels. All by itself, Greenland could bump sea levels by…

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…
