Observed fingerprint of a weakening Atlantic Ocean overturning circulation https://www.nature.com/articles/s41586-018-0006-5 The oceans’ circulation hasn’t been this sluggish in 1,000 years. That’s bad news. https://www.washingtonpost.com/news/energy-environment/wp/2018/04/11/the-oceans-circulation-hasnt-been-this-sluggish-in-1000-years-thats-bad-news Gulf Stream current at its weakest in 1,600 years, studies show https://www.theguardian.com/environment/2018/apr/11/critical-gulf-stream-current-weakest-for-1600-years-research-finds Shutdown of thermohaline circulation https://en.wikipedia.org/wiki/Shutdown_of_thermohaline_circulation Stronger evidence for a weaker Atlantic overturning circulation http://www.realclimate.org/index.php/archives/2018/04/stronger-evidence-for-a-weaker-atlantic-overturning-circulation North Atlantic ocean currents are…

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 /…

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 civilization has grown and thrived.…
