According to some estimates, black carbon may be responsible for as much as 18% of the planet's warming, making it the No. 2 contributor to climate change after carbon dioxide, which accounts for 40%. "The world could think that we just cut CO2 and the problem is solved and we all go home, but it's not," says Veerabhadran Ramanathan, a climatologist from the Scripps Institution of Oceanography and an expert on black carbon. "That's my nightmare."... [Read More]
