A seminal new Harvard study finds that CO2 has a direct, negative impact on human cognition at levels you and your children experience now. We explain how these findings are a game-changer for both public health and climate policy.
We spoke to former Bush EPA chief Christie Whitman on the Clean Power Plan, nuclear power, the urgent need for climate action, and why she "certainly" doesn't "talk about climate change ... to the Republicans" on Capitol Hill.
Does the AP suggest newspapers use the phrase “tobacco science doubters”? Of course not. Yet scientists have the same level of certainty about human-caused climate change as they about tobacco's health risks.
