What’s Happening to the Greenland Ice Sheet? (October 2017)

The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…

Little Algae creates Huge Melt Feedback on Greenland Ice

Algae responsible for large albedo feedback on Greenland’s frozen surface, not only soot and dust. We believe gathering measurements from the surface of Greenland ice is fundamental to advancing our understanding of the melting Arctic. http://darksnowproject.org Video via https://www.youtube.com/user/greenman3610 Dark Snow 2017 Update “Am I really seeing that?” is a common sensation here, as below,…

Expert explains link between Extreme Weather and Climate Change (March 2017)

Dr. Kevin Trenberth from the National Center for Atmospheric Research will explore the role of El Niño, climate change, and other influences on the weather and climate, and their role in recent costly and unusual extremes of weather, such as record breaking temperatures, drought and wildfires in the United States and around the world. –…

The dangerous silence on climate change and extreme weather

We know that CO2 emissions are bad for climate and subsequently the weather. We know that we have to do something about it, because if not things will turn really ugly with large scale carbon releases (i.e. permafrost melt). However, the current projected changes are bad for many, and because of irreversible changes. So why then is…

This image explains what is wrong with climate change coverage in the USA

Yesterday Obama delivered a historic speech about national security and climate change, at a US coast guard academy. Additionally the White House released a report, which summed up the conclusions from security experts on climate change. Today, if you go to Google News and type in “climate change”, you get something like below picture, 593 media articles on…

Arctic Lakes Show Climate On Thin Ice

ESA reported on February 3, 2014: Ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar imagery show how changes in our climate are affecting high-latitude environments. Changes in air temperature and winter precipitation over the last five decades have affected the timing, duration and thickness of the ice…

Stronger Winds Shift Heat to Deeper Pacific

Published on Feb 9, 2014 Heat stored in the western Pacific Ocean caused by an unprecedented strengthening of the equatorial trade winds appears to be largely responsible for the hiatus in surface warming observed over the past 13 years. New research published in the journal Nature Climate Change indicates that the dramatic acceleration in winds…
