Studies point to cognitive impairments at carbon dioxide levels believed possible by the end of this century, additional observation informed models tend to project higher warming scenarios, further research points to the possibility of self-reinforcing feedbacks in the climate system – again affecting the outcome of current unmitigated releases of heat-trapping gases to Earth’s atmosphere.…

Global Extreme Freak Weather July 2018 – Footage Compilation.
Tropical cyclones, which are called hurricanes in the Atlantic, are one of the most destructive weather phenomena. This presentation will explore the links between climate and tropical cyclones, with a focus on how hurricanes and tropical cyclones have changed in the past, and what we think they will do in the future. http://www.atkinson.cornell.edu/events/ClimateChangeSem.php Speaker: Gabriel…

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…
Past studies of Antarctica’s accelerated glacier retreat focused on regional trends, a new study now finds continental trends of over ten percent of marine terminating glaciers moving inland. Current peak retreat has been documented to be in the ballpark of 25 meters each single year. Read Chris Mooney’s Washington Post article study summary goo.gl/HuxtxL /…
