Worldwide Pond Scum Hysteria

Paul Chesser, Climate Strategies Watch

A new article in the journal Science attributes the "worldwide problem" of increased algae blooms in ponds and reservoirs to global warming. The News & Observer of Raleigh reports:

Warmer weather has created longer growing seasons. It has allowed the blue-green algae range to expand from Florida northward throughout the Southeast. When algae blooms die and decompose, they pull oxygen from the water and can cause fish kills. 

"The temperature change is playing into hands of blue-green algae," [Hans] Paerl [of the UNC-Chapel Hill Institute of Marine Sciences] said. "We have to be more diligent in reducing nutrients to slow down expansion into lakes that are now amenable to these blooms."

Except the global temperature has not increased for 10 years. What gives?
