Ah, spring. Sunnier days, warmer temperatures — and pollen season.

A Climate Central study shows growing seasons in most of the United States now average 16 days longer than in 1970. And a recent study in Nature Communications predicts our warming climate will increase annual total pollen emissions in the U.S. between 16 and 40 percent.

Yingxiao Zhang is a coauthor of that study. She’s a doctoral candidate in the Climate, Space Sciences and Engineering department at the University of Michigan, and she joined Climate Cast this week.
