A growing body of scientific evidence has led researchers to believe that in a warmer climate there will be no “tipping point” beyond which the Arctic sea ice cannot recover if temperatures start to decrease. Added to this is new research out of the University of Washington which suggests that even if the planet warmed enough to melt all polar sea ice, it could still recover if the temperatures cooled again.

Power plants play a huge role in emitting pollutants that make up the ozone. This pollution browns and blackens our horizons. We call it smog. Smog has been linked to premature deaths, thousands of emergency room visits, and tens of thousands of asthma attacks each year. Pollution in the ozone is particularly dangerous to small children and the elderly, who are often warned to stay indoors on days with poor air quality due to pollutants.
