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?
