The deadly extreme weather comes as a coalition of more than 400 organizations have called on the White House to stop issuing new fossil fuel leases on public lands and oceans. Among the call’s signatories are climate activist Tim DeChristopher, renowned environmentalist Bill McKibben, indigenous activist Winona LaDuke and environmental lawyer Robert F. Kennedy Jr. A number of labor, faith and environmental groups also joined the call, including the United Auto Workers Union, Unitarian Universalist Association, Physicians for Social Responsibility, the Indigenous Environmental Network and 350.org. More than 67 million acres of public land and ocean are already leased to the fossil fuel industry. The coalition says that declaring unleased oil, gas and coal on public lands as “unburnable” would accomplish more in the global fight against climate change than any other single action taken by the Obama administration.
