AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…

Glacial isostatic adjustment, why we have glacial and interglacial periods, how we can reconstruct climate history, and how the Earth is responding to the retreat of the continental glaciers. Video presentation by Meg Rosenburg (AGU Fall Meeting 2013) Post-glacial rebound

AGU: Human – induced climate change requires urgent action

2013, Climate Feedbacks, Science Talk, StudyLeave a comment

Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes. “Human activities are changing Earth’s climate. At the global level, atmospheric concentrations of carbon dioxide and other heat-trapping greenhouse gases have increased sharply since the Industrial Revolution. Fossil fuel burning dominates…

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
