Last Time Carbon Dioxide Levels Were This High: 15 Million Years Ago

By analyzing the chemistry of bubbles of ancient air trapped in Antarctic ice, scientists have been able to determine the composition of Earth’s atmosphere going back as far as 800,000 years, and they have developed a good understanding of how carbon dioxide levels have varied in the atmosphere since that time. But there has been…

Research closes gap between Warming and CO2 Rise

Feedbacks in the climate system – in which warming is linked to natural CO2 increase, driving further warming – may operate faster than previously thought. ACE CRC: Researchers use Antarctic and Greenland ice cores to examine temperature and CO2 changes during the largest natural climate change in Earth’s recent climate history: the warming out of…

Richard Alley: The Biggest Control Knob: Carbon Dioxide in Earth’s Climate History

In 2009, climate scientist Richard Alley (Pennsylvania State University) held the talk, “The Biggest Control Knob: Carbon Dioxide in Earth’s Climate History” (Bjerknes Lecture), at the American Geophysical Union Fall Meeting. CO2 is, and has always been, the biggest climate control knob in the Earth’s history https://mind.ofdan.ca/co2-is-and-has-always-been-the-biggest-climate-control-knob-in-the-earths-history 2015 release by AGU https://youtu.be/3UVb–2-PBg
