Artic Sea Ice and Albedo: Ice Free Season Growing 5 Days per Decade

Arctic ice autumn freeze-up starting later  - According to new research to be published in the forthcoming issue of Geophysical Research Letters, the ice-free season in the Arctic is growing by five days per decade. Analysis of satellite data by a team of researchers headed by Julienne Stroeve indicate increasing absorption of solar energy in the summer Arctic ocean is pushing…

Using satellite data researchers find effect of melting Arctic sea ice has greater impact on global warming than expected

Melting Arctic Sea Ice Causing More Warming Than Expected

Scientists have long modeled the expected warming due to the decreased albedo effect as melting Arctic sea ice exposes more open ocean. As early as the 1960′s climate researchers have predicted how this phenomenon will amplify global warming. Arctic ice melt, albedo and global warming Albedo is measured as a percentage, in this case the percentage of solar radiation a…

The jet stream powers weather, effects climate

Video Friday: Extreme Weather, the Jet Stream, and Global Warming

With the eastern half of the United States under a deep freeze and the phrase “polar vortex” making the rounds (and no, despite Rush Limbaugh’s breathless ranting, it isn’t a term just made up by evil climate scientists), we circle back around to the discussion of climate vs. weather  and get a grasp on how the jet stream works in this…

Alaska may have some of the most extreme impact from climate change

Video Friday: Climate Change Impacts on the Alaskan Ecosystem

The northern latitudes are experience some of the most dynamic impacts from climate change. Done by a student as a final project for a Climate Dynamics Class, this video explores some of the effects and consequences climate change will have in Alaska.   Featured image credit: Berkeley Lab, courtesy flickr

14 Steps to Reduce Black Carbon and Stabilize the Cryosphere

Climate change is causing unprecedented changes in the Earth’s regions of snow and ice, portents of profound, dramatic change for ecosystems and societies around the world, according to a joint report released by The World Bank and The International Cryosphere Climate Initiative (ICCI) November 4. The Earth’s cryosphere is warming more rapidly than anticipated – “at a pace unprecedentd in…

Video Friday: Misleading Claims of Arctic Sea Ice Rebound, The Daily Mail Lathers Up Deniers

The Daily Mail – Where space aliens and climate change are reported with equal knowledge and respect There have been many claims brought to my attention this week alleging the “final nail in the coffin” of anthropogenic global warming – the same nail that’s been fumbled around by deniers and the unfortunately misled for decades now. This time around it…
