See There has historically been much more CO2 in our atmosphere than exists today.

Dont let Al Gore see the facts...you'll take away his purpose in life.
I sorta bought Crichton's version of it in "State of Fear."
That it's a nonissue concerning the earth's natural rotation on its axis.

The site is interesting but irrelevant to global warming. It doesn't matter what the climate was like 200 million years ago, what caused it to change then.
Climatologists look at what's causing this change. Trying to find out why the earth's climate is changing now by looking at the creataceous period, is a bit like investigating 9/11 by looking at who tried to blow up Parliament in 1605.
The best line I've heard about global warming is:
Isn't global warming the reason that Yosemite is no longer under a sheet of ice??
Ahhhh...when talking about planetary climatology...geologic time matters, mh8782.
So, millions of years ago would be appropo.
i'm not a believer in global warming but i can never re-call in my entire life 100+ temperatures in the DFW area in the month of april and having to go through rolling brownouts. this looks like a summer here in texas that might be hotter than the summer of 1980
Not if global warming theory is correct. Studying paleoclimate can give us clues into how things may change, but it's not especially relevant to predicting would happen if CO2 levels were to double in such a short space of time (100-200 years)
The big issue is actually whether or not human activity contributes to global warming. Some people "believe" our efforts are too small to make a difference. Other people "believe" our efforts are just enough to make a difference.
I note that Mankind learned to use fire just about the start of the current period of glaciation.
The NORMAL situation before that was minimal glaciation and ocean levels much higher than at present. In fact, but for the glaciation at Antarctica, I would have a beach-front property, and would be able to step out onto my porch in the evening and watch the waves roll in on the East Coast.
It's possible I will get this all back if Antarctica melts soon.
The point you're missing is that in the past, the CO2 level has ALSO been higher (in some cases MUCH higher) than it is today. The rate of change means zip. What matters is the concentration in the atmosphere.
It's reasoning like this that makes folks susceptible to the pseudo-science of "global warming."
How long a time period is it you've been monitoring DFW weather?
Rounded to the nearest hundred-thousand years?
BTW, while 100 F yesterday was a record high, the record LOW for that date, 32 F, was set in 1999.
Seven years ago.
Were you fearing a new ice age at that time?
Searching for man made causes to assign to a normal global phenomnenon is folly.
