Global Warming Helps Cold Weather Plants in Sonoran Desert

An interesting study in the effects of global warming on a specific ecosystem:

Global warming is giving a boost to Sonoran Desert plants that have an edge during cold weather, according to new research.

While the temperature as a whole is going up:

In a previous study, Venable and his colleagues had examined the physiology of the nine species and found that some grow better under cold conditions and are more efficient at using water. Those species are now becoming more common as the changing climate shifts the onset of the winter rains.
