Hi there
Something interesting I ran into today on Earth and Sky:
Studies of twenty years of records of high altitude weather in the
Northern hemisphere shows that the air temperatures are warming earlier
each spring now than 2o yers ago. As a result, robins, who 20 years ago
spent early spring at low altitudes now arrive at high altitudes earlier.
