Annals of Global Warming: Octobers in the U.S. are 2°F warmer
From Climate Central: Octobers are warming across the U.S. with the increasing accumulation of greenhouse gases in the atmosphere. Since 1970, October temperatures have risen about 2°F. Warming throughout the fall is even stronger in some parts of the country, with the Northeast and the West warming the most. This warming can delay the start of some of the traditional cold season activities in cooler and mountainous climates, such as skiing. The warming trend also means first freezes occur later in the year, which can allow more insects to survive later into the year and make for a longer fall allergy season.
Since 1970, Octobers are 2 degrees warmer? No big deal?
See the caption. A lousy 2 degrees is a lot. It’s enough to:
Reduce the number of freezing days, allowing pine bark beetles in Colorado to escape death by freezing, and thereby kill more pine trees, faster.
Change October precipitation from snow, to rain. Rain instead of snow may cause regional flooding due to the rapid water dump; it may reduce snowpacks that provide water through the warmer months, effectively adding to drought threat.
Keep some prairie flowers alive longer, delaying migration of butterflies triggered by reduced food supply; ultimately this could cause butterflies and other migrating beneficial insects to migrate too late in the year.
No big deal, unless you live on Earth.
“What did you do when you learned CO2 was hurting the planet, Grandfather?” our grandchildren will well ask. Got an answer?

We've been soaking in the Bathtub for several months, long enough that some of the links we've used have gone to the Great Internet in the Sky.

My blog, Millard Fillmore's Bathtub, is a continuing experiment to test how to use blogs to improve and speed up learning processes for students, perhaps by making some of the courses actually interesting. It is a blog for teachers, to see if we can use blogs. It is for people interested in social studies and social studies education, to see if we can learn to get it right. It's a blog for science fans, to promote good science and good science policy. It's a blog for people interested in good government and how to achieve it.
