Recent data related to our global emissions of heat-trapping gases suggest that humanity may have reached a turning point, or even several. We may be moving from increasing emissions, to peaking and starting to decline. We could be close to such peaks, or even have passed it, for several of the main sources of greenhouse gases, including coal and deforestation—perhaps even for humanity’s total emissions.
If so, this would be a momentous occasion, reversing centuries of growing global warming pollution. But before we start celebrating, we should realize that peaking is not nearly enough.

Even though Louisiana is not among the areas that has seen the most increase in heavy precipitation events, the Southeastern US has seen an increase of 27 percent from 1958 to 2012. The straightforward explanation for heavier downpours is that warmer air can contain more water vapor than cooler air. Indeed, global measurements show that there is more water vapor in the air now. It follows that there is more water to come down when it rains. Read more >
