Melting Arctic Sea Ice Causing More Warming Than Expected

Using satellite data researchers find effect of melting Arctic sea ice has greater impact on global 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 surface reflects back into …

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

The jet stream powers weather, effects climate

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 video from The Film …

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 is the venerable and …

Video Friday: Greenland Ice Melt – Bellwether of Changing Climate

Scientists and Greenland Inuits confirm findings of leaked IPCC report Due out later this year, early drafts of the Fifth Assessment Report from the Intergovernmental Panel on Climate Change were leaked earlier this week, confirming what scientists have been saying now for years, even decades: global warming is real. Many see little change in the IPCC’s Fifth Report from its previous assessment published in …
