Another positive feedback loop that is causing climate change to happen even faster than anticipated by scientists.

ScienceDaily (Sep. 5, 2012) — Increased precipitation and river discharge in the Arctic has the potential to speed climate change, according to the results of a study led by Xiangdong Zhang, a scientist at the University of Alaska Fairbanks International Arctic Research Center.
"As the Earth's climate continues to change, the high-latitude North is becoming even wetter than before," Zhang says. "In particular, air moisture, precipitation and river discharge have increased, leading to a stronger water cycle. These recent changes may intensify climate system interactions and further advance climate change."
