Mid-April south of Tucson, and it topped out at 55 deg today. Should be warmer tomorrow, but this has been a cool spring.

The problem is that any warming or cooling will probably take place over a few hundred years, with variations up and down along the way. Makes it tough to look at 20 or 50 years of data and know the long term trend.

heck, we only get a 3 day forcast because there are too many vaiables and they are only right half the time.

Not exactly... Tucson NWS shows that February and March were quite a bit above average. The green range is the daily average

Daily perceptions only distort the big picture - but climate is over many years, not in our short term memory range...:^)

However, I think there are too many unknowns to give a 90% certainty to the computer models that go out into the next century - I would put it as less than 33%.

Random would be 50%, but grant $$ make it lower...:^)

I live in Green Bay, WI. Spring, when it finally shows up, is going to be cold.

I say bring on the global warming. It can't happen fast enough.
