For millions of Americans, summers are getting longer, winters are getting warmer and the impacts are showing up in their front yards.fresh green leaf branch under heavy rain in rainy season

A recent analysis by federal scientists shows that half of the country has seen its average lowest winter temperature rise by as much as 5 degrees in some areas over the past 30 years, altering what can grow where, particularly in areas normally prone to frost or freezing temperatures.

The data, reflected in the updated Plant Hardiness Zone Map in November, helps gardeners, farmers, insurers and other officials decide what to plant, how much to charge farmers for crop insurance and whether to expect insects like ticks carrying Lyme disease to continue migrating north. This was the first map update in 10 years.
