Sen. John Kerry (D-Mass.) on Tuesday said there’s a “calculated campaign of disinformation” on climate change that has stalled action on the issue and endangered the country.

“We are living through a story of disgraceful denial, back-pedaling and delay that has brought us perilously close to a climate change catastrophe,” Kerry said.

The Massachusetts senator’s lengthy floor speech called for the public to be “pounding on the doors of Congress” to act, and cataloged global perils such as drought, floods, wildfires, threatened coastlines, disease risks and more, noting “the danger we face could not be more real.”
