May 22, 2015 - California has a lot of negatives going on right now. It is in the middle of the worst drought the state has experienced since records were kept, watching its in-state and out-of-state water reserves dry up.

May 8, 2015 - We put 32.3 billion metric tons of CO2 into the atmosphere in 2014. That's the same amount as 2013. In some quarters that represents progress, a plateauing on carbon emissions. But the impact of continuing to pump gas into the atmosphere means CO2 continues to increase. The number should fall as the Northern Hemisphere heads into summer and plants absorb some of the CO2.
