Spring Coming Earlier, Study Says

Tired of winter? Good news: Spring arrives an average of 1.7 days earlier now than it did in the first half of the 20th century, according to a new study.

Summer, fall, and winter are also starting 1.7 days earlier. And there is less of a temperature difference between winter and summer.

The shifts, which are occurring over land (seasonal shifts are different over oceans), appear to stem from as-yet-to-be determined changes in the physics of the Earth’s climate system.
