Climate Research

A new study published this week in the Proceedings of the National Academy of Sciences advances the understanding of the link between weather extremes and global warming.

Scientists from the Potsdam Institute for Climate Impact Research say man-made climate change may slow down or stall wave-like weather flows in the Northern Hemisphere, leading to devastating extreme events like the U.S. drought of 2011 and the 2003 heatwave in Europe.

As this meteorological winter comes to an end, we’re taking a look back to see how winters have been changing overall in La Crosse. Some years have been unusually cold, others unusually warm, but the number of frigid days has been on a downward trend since 1970. On average, as the chart above shows, that number has dropped from 147 to 131 over 42 years.

This trend is happening all over the country, but in La Crosse, unlike in some places, the chart below shows that the overall trend has actually been upward if you go for more than 100 years — proof that even a world that is warming overall, local weather patterns mean that some locations will see more cooler days, at least in some seasons.
