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 /…
