The AMOC of the Ice Age Was Warmer Than Once Thought - Eos
An analysis of sediment cores indicates that North Atlantic waters were relatively warm and continued to circulate even under major climate stress during the Last Glacial Maximum.

Why is the far side of the Moon so different from the near side? The answer may lie in a primordial asteroid impact, based on data from the Chang'e-6 mission. My latest for @eos.org has the story: eos.org/articles/pri... 🧪🔭
