This year, instead of waiting for the "normal" last frost May 15, I began planting in late March, a month and a half early. We had not hard frosts after March 30, and two wet snowfalls of 3-4" each in April that melted and gave needed water. Of course, the mountains are known for their variability, but this is really something different. The rapidity of change noted by the Dept. of Agriculture, should be absolute proof of AGW and extrapolated, CAGW. At least they admit the climate of the USA has warmed 5*F since 1993.
What people have not been mentioning is that since 1950, oceanic acidification from human caused CO2 increase has killed 40% of phytoplankton. That is the source of 40% of our oxygen! (-16%)
People have also cut down 57% of the world's rainforests which supplied a similar percentage of our O2. (-27%)http://www.rain-tree.com/facts.htm
Add them up and we have so far lost 43% of our planetary oxygen making ability(and CO2 absorption ability, similar). The rainforests are estimated to get to be 80-90% gone by 2025. Obviously, with continued burning and deforestation by humans, and breathing by all animal life and aerobic bacteria, the nearly 21% O2 we once had will begin falling, or already has.
It sure looks like 2050 will be +12*F(+6*C) and O2 down to 19% or less, roughly. The world's aquifers will be mostly drained, at least the one's around where most people live(loss of our Ogallala before 2040 will be devastating). Ocean level rise will have inundated places like Bangladesh. World good farm soil will be at over 80% loss, in depth, health, and area, from what it had been. People will be dying at the rate of 400 million per year, or more.
Glad I won't be around. Can't say they weren't warned.
