Is the dramatic decline of Arctic sea ice, spurred by manmade global warming, making the weather where we live more extreme? Several recent studies have made this claim. But a new study finds little evidence to support the idea that the plummeting Arctic sea ice has meaningfully changed our weather patterns. The research, published today in Geophysical Research Letters, says links between declining Arctic sea ice and extreme weather are "an artifact of the methodology" and not real…"Just as a river of water tends to meander when it reaches the gentle slopes of coastal plains, a weaker jet stream tends to have steeper north-south waves," explained Rutgers University atmospheric professor Jennifer Francis, in a guest blog post here at CWG. "The slower the waves move, the longer the weather associated with them will persist."
