• New Understanding About the Role of Soil Fauna in Regulating the Carbon Cycle

    YCEI postdoctoral researcher Thomas Crowther published important new findings in Proceedings of the National Academy of Sciences about the relationship between soil animals feeding on microbes which can otherwise exacerbate the impacts of climate change.

  • Hundreds Gather to Consider Initiatives for East African Climate & Health

    Representatives of government and NGOs from around the Horn of Africa and Arabia gathered in Djibouti last week where a Yale-led Taskforce met with the Republic's President Ismail Omar Guelleh to present their vision for high-resolution climate modeling of the region.

  • YCEI-sponsored Global Biodiversity Workshop

    Walter Jetz convenes fellow FutureEarth researchers working to "accelerate our transformations to a sustainable world." FutureEarth is a global research platform supported by the International Council for Science, the World Meteorological Organization and multiple agencies of the United Nations.

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

    A new publication in Proceedings of the National Academy of Sciences by Dr. Peter Douglas and YCEI Director Mark Pagani, shows how isotopic analysis yields fresh understanding of how drought impacted the Maya, and how they apparently altered their agricultural practices in turn.

  • Djibouti Delegation Meets with YCEI Climate Assessment Task Force

    His Excellency Dr. Nabil Mohamed Ahmed and Dr. Awaleh Osman of the Center for Research and Studies of Djibouti (CERD) climbing "The Giant Steps" trail for a better view of New Haven and Yale after their meeting with YCEI climate task force scientists.

Health studies on the impact of heat waves have focused for the most part on using temperature differences and metrics such as humidity index to assign heat stress, but may not be fully accounting for the physiological response to heat. Algorithms that more accurately characterize exposure by including moisture terms to calculate Wet Bulb Globe Temperature (WBGT) could improve heat stress studies. WBGT is a heat metric that more accurately reflects heat dissipation; or the ability of the atmosphere to allow

As climate change continues and temperatures rise, people around the world will have to adapt to new climate realities. Globally, household incomes are expected to continue rising over the coming decades, so as average temperatures increase most people will likely respond by increasing their use of air conditioning, thus potentially increasing electricity consumption and greenhouse gas emissions.

A recent study of income growth, increasing…

Advance arrangement with homeowners and industry has allowed Clifton R. Musser Professor of Hydrology Jim Saiers to launch the first ever study of groundwater quality impacts before, during, and after …


Jim Saiers grew up near Susquehanna County, close to the epicenter of Marcellus Shale exploration. He is back there now, at work on a paradigm-setting approach to testing the groundwater quality impacts of hydraulic fracturing.
