Study finds warm springtimes in Hudson Bay lead to hot summers further south
Arctic sea ice has diminished drastically over the last 40 years. Now a study shows that the southern half of the US may be suffering from more summer heatwaves as a consequence.
Dagmar Budikova, a climatologist at Illinois State University, and colleagues used satellite data to measure the ebb and flow of Arctic sea ice in the Hudson Bay region since 1979 and compared this with heatwave frequency across the US. Their results, published in the Journal of Geophysical Research: Atmospheres, show that summer heatwaves were far more common across the southern US in the years when the Hudson Bay basin experienced a warm spring and reduced sea ice.
