Cliff Mass reports that less snow has been falling in Washington State for the last 20 years. “Global warming is occurring,” he concludes. Also in trouble due to declining snow are New England and Midwestern resorts.
The loss of sandy beaches due to climate-aggravated sea level rises is also troubling, and the problem is accelerating. The National Science Foundation’s Metro East Coast report says that beach erosion will likely double by the 2020s, increase from three- to six-fold by the 2050s and by as much as 10-fold by the 2080s. Already, sand loss has led to large beach replenishment efforts by the Army Corps of Engineers.
And keep plenty of calamine lotion on hand. Researchers at Duke University found that some vines—including poison ivy—may thrive exponentially in a warmer climate. Experiments showed that poison ivy growing in a carbon dioxide-rich environment grew about three times larger than normal and produced significantly more urushiol, the allergenic substance that causes rashes.
Another indicator of increased warming is the retreat of glaciers across western North America. This troubling phenomenon is especially noticeable in the Waterton
