President Obama's efforts at the Paris climate talks helped to achieve a strong global agreement that will set the world on a united path to combat climate change. But his deeds in Paris stand in contrast to a looming offshore drilling decision by his administration that could jeopardize his strong environmental legacy and the leadership position of the United States at this critical juncture.

When the administration announced its rejection of the Keystone XL pipeline ahead of the Paris climate talks, the decision was highlighted as a major step forward from the United States on reducing our reliance on energy sources that emit greenhouse gas emissions. But earlier this year, the administration announced a plan to open the Atlantic from Virginia to Georgia to offshore oil and gas drilling, a decision that is a major shift in federal policy and entirely inconsistent with other efforts to reduce carbon emissions and slow the march of climate change.
