Okay, I did a bit of research. It seems that just after the end of the
last major ice age, 12,000 years ago (before modern civilzation), the global
temperature jumped by about 14 degrees (F) in just a few decades. This
article:

http://www.spacedaily.com/news/climate-04k.html

Cites several other examples of rapid climate change. Two particularly
interesting paragraphs:

""Technically, an abrupt climate change occurs when the climate system is
forced to cross some threshold, triggering a transition to a new state at a
rate determined by the climate system itself and faSter than the cause,"
according to a definition developed by the National Research Council.

Abrupt change needs a trigger, an amplifier -- some mechanism to have the
trigger affect a large area -- and a source of persistence. It turns out
lots of triggers have been identified, for example, an accumulation of
carbon dioxide in the atmosphere, as is occurring now.""

If someone claims that there was a temperature increase of "14 degrees (F) in
just a few decades"
some time in the past, they certainly can't claim it was caused by loading
the atmosphere with
carbon dioxide in just a few decades.

It is not comparable.
.
.
Speaking of which, there's disagreement on whether an increase in CO2 leads
to an increase in temperature, or if an increase in temperature leads to an
increase in CO2. Ice core samples and other evidence suggest that the planet
warmed first, and then experienced an increase in CO2 levels.

Which in no way discounts the effects of CO2 on the climate.

Holyoke to clear the rental property, and then to dig out my grandmothers
car out , the whole deal is gonna take 5 hours I bet.
Al Gore should the hell up, what a moron...

You as a layman wont be able to see the change. If you expect to see the
change within the short time till your death, you will probably be an
angry old man whining about some porposterous observation some political
official in the public eye has made....

"Based on the latest comprehensive weather station data, The Arbor Day
Foundation has just released a new 2006 arborday.org Hardiness Zone
Map which separates the country into ten different temperature zones
to help people select the right trees to plant where they live.
The new map reflects that many areas have become warmer since 1990
when the last USDA hardiness zone map was published. Significant
portions of many states have shifted at least one full hardiness zone.
Much of Illinois, Indiana, and Ohio, for example, have shifted from
Zone 5 to a warmer Zone 6. Some areas around the country have even
warmed two full zones."
