Western Slope Skies - Light Pollution and Urban Ecosystem Timing – Who woulda thought?

An article in the international journal Nature Cities by Lvlv Wang and co-authors document the effect of light pollution on the growing season in 428 Northern Hemisphere cities between 2014 and 2022. They note that the typical growing season is controlled by heat and light. While cities are getting warmer due to climate change, they are also getting brighter due to excessive lighting. After controlling for the warming effect, they found that the excessive light was extending the growing season.
