As many as 40,000 protesters from 30 states descended on the White House on Sunday and demanded that President Obama kill the proposed Keystone XL oil sands pipeline. By the estimates of organizers, it was the biggest protest march for climate change action in the nation's history.
In about 18 cities from Boston to Los Angeles, thousands more participated in solidarity rallies—and helped garner unusual nationwide media attention for an issue that has typically slipped under the local media radar.
National environmental activists have made the Keystone XL a test of Obama's climate promises, as well as the cornerstone issue of a mushrooming grassroots movement to turn climate action into a moral issue. The pipeline would carry crude from the Canadian tar sands to Texas refineries and deepen U.S. dependence on a form of oil that produces more greenhouse gas emissions than conventional oil.
The movement is emerging as the biggest environmental protest effort in decades. In recent weeks, protests have sprung up across the country for the first time to stop oil sands import pipelines on climate grounds. Last week, 50 people were arrested at the White House in civil disobedience over the Keystone XL.
Sunday's event, led by advocacy groups 350.org and Sierra Club, was the third and largest pipeline demonstration at the White House in 18 months. A decision by the Obama administration on the Keystone XL is expected later this year.
