Global efforts to respond to climate change are so far insufficient, making it time to begin studying technologies to reflect sunlight away from the Earth to cool it down temporarily, said a new report from the United Nations published on Monday.

Reducing greenhouse gas emissions is the only way to permanently slow global warming, but worldwide efforts to reduce greenhouse gas emissions are currently “not on track to meet the 1.5° Celsius Paris Agreement goal,” the U.N.
