Jet Stream Stalled over Sweden Climate Weather Connection Explained

This heatwave across much of the northern hemisphere could continue for weeks, and possibly even months. And accelerated warming in the Arctic compared to the rest of the planet could be a key contributor. https://www.newscientist.com/article/2174889-warming-arctic-could-be-behind-heatwave-sweeping-northern-hemisphere/ Jennifer Francis (Rutgers University), speaks March 2018 about weather changes. And how are those related to climate change? Full talk…

Roger Revelle’s 1980 Discussion of CO2 and Climate Risks

Roger Revelle, is a pioneering researcher in the study of the human influence on the atmosphere, carbon cycle and climate https://dotearth.blogs.nytimes.com/2012/05/31/roger-revelles-1980-discussion-of-co2-and-climate-risks In 1980, then director of Scripps Institution of Oceanography, Revelle gave the talk “The Role of the Oceans in Earth’s Climate and Carbon Budget” at Lawrence Livermore National Labs. He gives a great overview…

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…
