Gabrielle Sigel, Co-Chair of Jenner & Block's Climate and Clean Technology Law Practice, has written a comprehensive review of climate change law during President Obama's first term: Climate Change Law in Review, 2009-2012: Obama's First Term Changes the Climate on Climate Change. The article explores the changes and challenges in climate change law that occurred over the last four years. Ms. Sigel analyzes the actions taken by President Obama's EPA, and other federal agencies, ground-breaking legal decisions in the courts, and attempts by Congress to address these issues. Ms. Sigel also explores U.S. participation in climate action in the international sphere. The article begins:
"At the close of Barack Obama's first term as President, he was criticized by many for having done little to address climate change and by others for having done too much. Regardless of whether one thought it too much or too little, between 2009 and 2012, there was significant new government action attempting to address the effects of climate change. Notably, this climate action came primarily out of the Executive Branch, using statutes previously passed by the Legislative Branch, and challenged and defended – typically successfully – in the Judicial Branch."
