Welcome

  • Yale Climate & Energy Institute | 2009 - 2016

    From 2009 to 2016, Yale Climate & Energy Institute promoted and funded multidisciplinary research at Yale on climate change and its links to modern energy use. This web page is an archive of the activities and accomplishments of YCEI, which closed on June 30, 2016.

  • A More Nuanced Look at Climate Change and the Fall of the Maya

    In an article in the May 2015 Proceedings of the National Academy of Sciences, Peter Douglas and former YCEI director Mark Pagani show how isotopic analysis yields fresh understanding of the impacts of droughts on the Maya peoples of Mesoamerica.

  • Understanding Solid Deformation by Fluids

    Chris MacMinn, a former YCEI postdoctoral Fellow now at Oxford, developed a new experimental system for studying how high-pressure fluids deform rock, leading to new insights into processes such as hydraulic fracturing and carbon sequestration.

  • Yale Climate & Energy Institute Newsletter

    Our Fall 2014 newsletter reviews six years of activity at YCEI that helped jump start multidisciplinary research in climate and energy at Yale. View it online here.

  • Monsoon Forecasts For Those Who Need It Most

    Yale professor Bill Boos has created a website to provide weather forecasts for the drenching seasonal storms called monsoons that affect billions of people, many of whom are not served by regular forecasts. YCEI sponsored an international forum on monsoons in April 2015.

A new paper in Nature Geoscience finds that “transient climate sensitivity,” the fast temperature rise that accompanies increases in atmospheric CO2, may be much higher than previously thought. The reason is widespread sulfate pollution from man-made and natural sources, which has tempered the warming that the world would otherwise be seeing at current levels of atmospheric CO2. This conclusion is based on research funded by YCEI and led by Yale atmospheric scientist Trude Storelvmo. Prior studies that did not fully account for the cooling influence of airborne particles …

New analytical techniques that allow ice cores to be sampled continuously for more chemical species continue to re-write the history of volcanism. The latest publication from YCEI postdoctoral fellow Francis Ludlow (Sigl et al, December 2015) finds new dates and magnitudes for historic eruptions dating back 2000 years, and concludes that they were the main driver of abrupt summer cooling in Europe. The new record alters what we know, and thought we knew, about European history, and will improve efforts to develop better climate models…

For the second time in a month, scientists at Yale University have found evidence that current models of global climate may be underestimating how much warming will occur…

Michael Mann and Trude Storelvmo discuss her group’s latest atmospheric research, and what it implies for scientists’ efforts to predict average future temperatures using global climate models.
