• Antarctica's Climate Resembled California's 50MM Years Ago

    "Clumped" isotopes of carbon and oxygen from Antarctica and the Southern Ocean reveal a dramatically warmer climate than today. Sea surface temperatures in excess of 20C above the present day suggest just how much global warming is amplified at the poles.

  • Karen Seto Coordinates New IPCC Chapter

    75-80% of the world's population will live in cities by the year 2050. Infrastructure for another two billion humans has yet to be built. How should it be done in order to minimize contributions to climate change? Karen Seto was Coordinating Lead Author on the new urbanization chapter of the latest Working Group III report.

  • YCEI Honors IPCC Chair Rajendra Pachauri

    Founding Director Pachauri holds a hockey stick, an emblem of the potential trajectory of earth's temperature, presented by Yale President Peter Salovey. The gift bears signatures of Yale Presidents, top climate scientists and Coach Keith Allain of the Yale Bulldogs 2013 National Championship hockey team.

  • Chikungunya Makes Ready for Landfall

    A virus mutates, a mosquito adapts, and suddenly climate "feedback" takes on a whole new meaning. The chikungunya epidemic racing through the Caribbean poses no risk to most Americans. But that could change if Asian tiger mosquito, one of the world's most invasive pests again becomes a primary carrier.

  • Culture and Arctic Climate Change

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

In the provocative new book “Supply Shock,” ecological economist Brian Czech argues that perpetual economic growth is a doomed policy and that the world must transition to a steady state economy to curb over-exploitation of natural resources and climate change.  Climate change is driven by anthropogenic inputs of carbon dioxide, methane, and other gases…

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…

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…


IPCC Chairman Rajendra Pachauri applauds Shell Oil for internally assuming a $40/ton price on carbon for their long-term planning needs.  He suggests that a peer-reviewed study could significantly advance the single measure which many feel could get CO2 emissions under control.
