Just in time for the cooler spring that has swept the nation — complete with unseasonal snow in the Rockies region — scientists with the University of Manchester said pollution actually brings on climate cooling, not warming.

The logic is that manmade pollutants make clouds brighter, and that impacts how sunlight is allowed to shine — and that brings about cooler temps, scientists say, TG Daily reported.

“We discovered that organic compounds such as those formed from forest emissions or from vehicle exhausts, affect the number of droplets in a cloud and hence its brightness, so affecting climate,” said one study author, Gordon McFiggans, from the University of Manchester’s School of Earth, Atmospheric and Environmental Sciences, in TD Daily.

The findings come as various regions around the nation are reporting near-record low temperatures for the spring months.

The Star-Telegram in Texas, for instance, reported that Friday brought record lows of 39 degrees. And in both March and April, temperatures for the North Texas region hit the lowest levels in three years. More than a foot of snow fell in the Rockies region last week, and Iowa, Minnesota and Wisconsin were also hit with record snowfall levels for May over the past few days.
