• Energy/Future 2030: April 17th | Kroon Hall

    Join us for the Fifth YCEI Annual Conference, a critical look at trends, technologies and policies likely to determine the world's energy mix over the next 15 years. The event will honor Rajendra Pachauri, chair of IPCC and first director of YCEI, who will give the closing keynote on energy and climate projections.

  • Soil Texture Controls Microbial Response to Deforestation

    Microbial communities in the soil regulate the release of more CO2 than all anthropogenic sources combined. YCEI post-doc Thomas Crowther reports that soil texture dwarfs every other variable in predicting how those communities respond to deforestation.

  • El Nino In the Pliocene. Same As It Ever Was?

    Yale researchers report that temperature gradients existed across the Pacific during a time when CO2 levels were similar to those of today. Their findings challenge a long-held consensus about a permanent El Nino, suggesting temperatures then were higher than previously thought, and may be heading in that direction again.

  • Paleo-storms Along the Connecticut Coast

    Lisa Weber, a Master of Environmental Science graduate from the Yale School of Forestry and Environmental Studies, discusses her YCEI funded research into the frequency and intensity of ancient hurricanes along Connecticut’s valuable -- and vulnerable -- coastline.

  • Climate and Culture in the Arctic

    Physical Oceanographer Mary-Louise Timmermans hosts a 2-day workshop including historians, anthropologists, marine biologists and climate scientists to discuss the perspective of their respective disciplines in the context of historic climate change and its effects on people of the Arctic.

After much of the U.S. experienced an unusually long and cold winter, many ask whether climate change is still happening.  There has, in fact, been little change in global mean annual temperature since the early 2000s leaving scientists struggling to figure out where the heat associated with continuing greenhouse gas emissions has gone.  In a recent paper…

A presumed benefit of global warming is the assumption that warmer winter temperatures might decrease excessive winter deaths (EWDs) common in temperate climates. EWDs are defined as the difference between the number of deaths in a region during winter months (December – March) and the average of the proceeding fall and subsequent spring deaths.

For forty years, Royal Dutch Shell has committed significant intellectual resources to forecasting the future.  Multiple futures, in the form of alternative scenarios presented as if each had an equal chance to unfold as time reels forward. They are…


The same week as he oversaw release of the most recent IPCC report, “Patchy” is honored for his service as YCEI’s Founding Director.  He reflects here on when he first became concerned about climate, and the hope he sees now that  major corporations are planning for a lower carbon future.
