CO2 was supposed to make Arctic lakes grow, but they're allegedly shrinking; CO2 blamed

An Unusual Phenomenon: Vanishing Arctic Lakes - International Business Times

What is surprising, according to Hinzman, is that the northern region received higher-than-average amounts of rain during the 10-year study period. In addition, the warmer temperature across the region should be decreasing the snow pack which should also boost the lake. Despite these factors, however, the lakes are vanishing contrary to known physical processes that suggest that the lakes should be growing, not shrinking.

According to Hinzman, this could be a sign of climate change.
