To avoid catastrophic climate change, we need to put a stop to all new fossil-fuel development and accelerate a just transition to a clean-energy economy.
The only way to achieve this is to keep coal, oil and gas in the ground.
President Obama has executive authority to direct federal agencies to stop leasing public fossil fuels and he should define his climate legacy by doing just that.
More than 67 million acres — an area 55 times larger than Grand Canyon National Park — is already leased to the fossil fuel industry.
Obama has added an additional 36 million acres of public land and ocean to that total.
