ICE ALIVE – Documenting Life and Rapid Change

Joseph Cook is taking a closer look at the microbial life that can be found all over the planet’s glaciers and ice sheets. It is increasingly clear that this rich ecosystem affects the melt rates of polar ice and snow and could be accelerating climate change. Narrated by Jim Al-Khalili and starring Chris Hadfield. For…

Climate Expert Mike Mann: Understanding Dire Climate Predictions

This 2016 lecture featuring Michael E Mann http://www.meteo.psu.edu/holocene/public_html/Mann/index.php begins with a review of the now-solid evidence for a human influence on the climate of recent decades. Such evidence includes instrumental measurements available for the past two centuries, paleoclimate observations spanning more than a millennium, and comparisons of the predictions from computer models with observed patterns…

Watch Bubbling Alaska Lakes Catch on Fire #Methane

Seeping methane is driving a global warming feedback loop. Some Arctic lakes are starting to look like witches’ cauldrons. The above video shows an increasingly common site in northern latitudes. As global warming heats these areas up, the frozen ground is melting. And when permafrost turns from solid ground to looser mud, it releases gases…

Ice sheet deglaciation and methane emissions, with the scope on Greenland’s melt season

On June 9 2016, Nuuk, the capital of Greenland, reached the warmest temperature ever recorded for the month of June anywhere on the island, 24 degrees Celsius (75 degrees Fahrenheit). An article from NSDIC, published June 22 elaborated on the broader situation: Surface melting on Greenland’s Ice Sheet proceeded at a brisk pace, with three…

NASA: Coolants Contribute to Ozone Depletion and are strong Greenhouse Gases

According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption. A class of widely used chemical coolants known as hydrofluorocarbons (HFC) contributes to ozone…
