Climate activists embrace extreme tactics, violence as deadline to 'save the planet' draws near

Climate change activists in the U.S. and across the world are ramping up their actions in what they say is an attempt to save the planet. 

In recent months, far-left activists have glued themselves to famous paintings, disrupted new pipeline construction, scaled buildings, blocked rush-hour traffic, lit themselves on fire, threatened to  disrupt the Congressional Baseball Game and slashed tires of random sport utility vehicles (SUV) in cities around the world. 

The activists have argued that world governments have failed citizens by not acting aggressively enough to enact policies curbing warming.

"We cannot continue to wait around for a bunch of corporate shills in Congress to do nothing while people are dying," Greenpeace USA senior climate campaigner Ashley Thomson said last week.
