Antarctica ice loss has tripled in past decade

Mass balance of the Antarctic Ice Sheet from 1992 to 2017 – ocean-driven melting has caused rates of ice loss from West Antarctica to increase from 53 ± 29 billion to 159 ± 26 billion tonnes per year; ice-shelf collapse has increased the rate of ice loss from the Antarctic Peninsula from 7 ± 13 billion to 33 ± 16 billion tonnes per…

French President to U.S. Congress: There is No Planet B!

“I believe in building a better future for our children, which requires offering them a planet that is still habitable in 25 years,” he says. Macron is confident that “one day” the U.S. will recommit to the Paris climate agreement. After all, as he says in the address, “there is no Planet B.” https://grist.org/briefly/the-french-president-gave-america-the-climate-change-speech-that-trump-never-will Full…

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…

This new Antarctic Discovery will affect You massively

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 /…

Thousands of little Volcano like Hills form in Arctic!

Scientist speculated that pingos may erupt and lead to the creation of craters – small lakes, thaw ponds. New satellite observations reveal continuous trend. The Siberian Times article, Pingo in Arctic goo.gl/mwNnEF / http://siberiantimes.com/other/others/news/crater-formed-by-exploding-pingo-in-arctic-erupts-a-second-time-from-methane-emissions/ The trend from frozen tundra soils shifting to thermokarst erosion and thaw ponds, may in the future be exacerbated by increased…

The New Record Low Arctic Sea Ice and Our Weather

Arctic sea ice decline has long been projected to occur. 2018 and 2017 are the two lowest winter time Arctic sea ice records observed. Disappearing sea ice and moisture transport into the Arctic are believed to cause something called Arctic amplification, which in turn has been linked to two effects (weaker westerly winds, and intensified…

Waking the Climate Giant

Bill McGuire (University College London) speaks about responses from the Earth crust in this 2016 lecture. He wrote a book on the subject, available at https://www.geolsoc.org.uk/Publications/Bookshop/Search?k=waking&sortexpr=Publication%20Date%20Desc An astonishing transformation over the last 20,000 years has seen our planet flip from a frigid wasteland into the temperate world upon which our civilisation has grown and thrived.…
