Global warming brings spring, and sniffles, earlier
Have your seasonal allergies showed up a bit early this year? It may not be you, it could be that the spring, and its pollen has showed up early. Beth recently wrote about using Henry David Thoreau's journals to track the early arrival of spring. In May 1868, trees in a cemetery in Lowell, Mass, as captured in Thoreau's journals were barren. The same spot in 2005? Flowers everywhere.Here's more evidence from a recent AP article:
- Sneezes coming early in Philly. On March 9th of this year, maple pollen was already heavy in the air. Two decades ago, that pollen couldn't even be detected until late April.
- In California, the field skipper sachem (a butterfly) was fluttering on March 12th. Twenty-five years ago, the sachem wouldn't show up until at least mid-April.
- D.C.'s cherry trees are going to peak at the end of this month; thirty years ago, they waited until at least April 5th.

Humm?? Just had a light snow here in SouthEast TN... Very late for that here. Looks we will have to wait longer than usual for spring to break here!

That's been true in Austin -- then again, I feel like I"m always sneezing down here. :)
