Lingering Summer Warmth
A Climate Central analysis found that summer warmth is intruding upon our colder seasons, with 50% (122) of the cities analyzed recording summer temperatures that last a week or more longer than they did 50 years ago.
The intrusion of summer warmth into our colder seasons is presenting a challenge for native plant and animal species whose life cycles are scheduled around the once-reliable seasonal changes of the temperate North American climate.
Lingering warmth has implications for fall harvests and agriculture. Colder temperatures help to keep many invasive and pest species at bay, so the invasion of summer warmth into our colder seasons could favor crop weeds and pests— potentially resulting in losses for farmers.
While a longer growing season can mean more time for growing and harvesting crops, rising temperatures and other climate change impacts have a damaging effect on U.S. agriculture.
