An increase in arctic temperatures as a result of global warming could result in significantly higher levels of carbon dioxide being released into the atmosphere. This, in turn, could fuel global warming even more.
A study supported by the Office of Polar Programs at the National Science Foundation discovered that artificially elevating summer temperatures by about 3.6 [degrees] F on plots of arctic tundra increased the [CO.sub.2] emissions by 26 to 38% under normal snowfall. When snowfall on some plots was increased--which is one possibility with global warming--[CO.sub.2] emissions increased 112 to 326%.
"We found significant losses of carbon dioxide ...
