Register today for the Bulletin of the Atomic Scientists’ annual Clock Symposium. Over the last 68 years, the Bulletin has reset the minute hand on their iconic Doomsday Clock 21 times, most recently in January, 2015, when the Clock moved from five minutes to midnight to three. Existential threats resulting from a rapidly changing climate figured heavily into the Clock change last year, and the Symposium this year puts climate change front and center. You won’t want to miss the points made by Sivan Kartha, Peter Ogden, Richard Somerville, and Robert Socolow as they discuss the Paris climate negotiations and energy solutions for a warming planet.

The Symposium is free and open to the public.

Areas of Focus: Environment
Producing and using energy damages people’s health and the environment. EPIC research is quantifying the social costs of energy choices and uncovering policies that help protect health while facilitating growth.
Climate Change

Climate change is an urgent global challenge. EPIC research is helping to assess its impacts, quantify its costs, and identify an efficient set of policies to reduce emissions and adapt...
Climate Law & Policy
Climate Law & Policy
As countries around the world implement policies to confront climate change, EPIC research is calculating which policies will have the most impact for the least cost.
