Global Warming Myths

A couple of recent articles have further suggested that global warming's effects maybe overstated:

"Though it might seem he is trying to upstage the hurricane center, his real intent, Frank said, is to dispute that global warming has led to more active Atlantic tropical storm seasons, as several meteorological studies have asserted."

"We examine tropospheric temperature trends of 67 runs from 22 Climate of the 20th Century model simulations and try to reconcile them with the best available updated observations (in the tropics during the satellite era). Model results and observed temperature trends are in disagreement in most of the tropical troposphere, being separated by more than twice the uncertainty of the model mean. In layers near 5 km, the modelled trend is 100 to 300% higher than observed, and, above 8 km, modelled and observed trends have opposite signs."

"There's a natural cause that may account for much of the Arctic warming, which has melted sea ice, ice sheets and glaciers, according to a study published Thursday in the journal Nature. New research points a finger at a natural and cyclical increase in the amount of energy in the atmosphere that moves from south to north around the Arctic Circle."
