Arctic Sea Ice and Permafrost Status Report 2017

The Arctic is warming faster than anywhere else on Earth, affecting people in the region, fish and wildlife they depend on for food, and their environment. This unprecedented change has ramifications far beyond the region for the global economy, weather, climate, sea level, trade and security. Watch the full Arctic Report 2017 AGU press conference…

Arctic Sea Ice Extent 2nd lowest on Record for the Date

Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average… https://twitter.com/ZLabe/status/932663163476045825

Arctic Climate Feedbacks [peer-reviewed]

This peer-reviewed educational video introduces feedbacks that are important in the Arctic climate system. It is aimed at an undergraduate non-science major level. The video was produced by a team of CIRES scientists in collaboration with CIRES Education and Outreach. Video production was funded by Professor Jennifer Kay’s CAREER Award from the National Science Foundation…

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…

Arctic and Antarctic sea ice at lowest since satellites began to measure 1979

Sea Ice Extent Sinks to Record Lows at Both Poles Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. And on the opposite side of the planet, on March 3…

NASA: 2016 Arctic Sea Ice Minimum Ties Second Lowest on Record

Arctic sea ice appeared to have reached its annual lowest extent on Sept. 10, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at Boulder reported today. An analysis of satellite data showed that at 1.60 million square miles (4.14 million square kilometers), the 2016 Arctic sea ice…

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.…

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…

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…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

With further Arctic Amplification, How fast will Greenhouse Gas emissions accelerate in the Arctic Circle?

Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere.       CH4 Release The following studies explore the release of CH4 emissions in the Arctic region. OBSERVATION…
