Man changed climate for 8,000 years?

That real effect study was being done at WAZZU a decade ago. I understand their conclusions caused quite a stink....

[Lucky Dog]

Yes, but was it a global warming stink?

[fiscally_right]

Couldn't the chart just as likely demostrate that CO2 increase causes Temperature increase? Not that I believe this, but correlation is not causation. Or rather, it doesn't suggest which caused which. Chicken or the egg, and all.

[Timocrat]

According to your chart were fixing to have another ice age here shortly - they seem to have appeared with some regularity. I think I'll go out and drive my suv around to help put off the next one. Don't thank me now.

Crazy thing is, those were the idyllic days when mankind lived in perfect harmony with the pristine, Eden-like "Gaia". The envirowackos will be deeply saddened.

The only answer is to kill all humans.

Less than a million people 8,000 years ago causing global warming in ludicrous. In light of the recent solar activity I am more inclined to vote the sun. It seems more reasonable that the sun itself could be the cause.

Others have studied the ice too:

SUN IN FRENZY SINCE 1940
"German scientists who have created a 1,000-year-record of sunspots said Wednesday they discovered the Sun has been in a frenzy since 1940 and this may be a factor in global warming...
The research, based on the quantities of the isotope beryllium 10 found in ice bores from Greenland and the Antarctic, challenges the belief that carbon dioxide from cars and coal fires and other greenhouse gases are the only cause of recent warmer climates."

I like it. Beano for Bovines! Maybe we can get some EPA money like the hustlers behind these "models".

ANCHORAGE, ALASKA Wednesday, December 10, 2003 -- Scientists were speechless today when a Klondike SUV has uncovered in a glacier core-dated to 6,000 B.C.E. ...

I believe your rendition is what the chart was meant to represent; I was having fun...

[TheDon]

Notice that sentence is the last in the article, not the first.

While you're correct that correlation is not causation, a cause must occur before the suspected effect.

Note that the temperature increases before the CO2 does. The temperature increase may (or may not) cause the CO2 increase. The CO2 increase after the temperature increase certainly didn't cause the temperature to go up.

We will have to be careful with our research. If our Bovine Beano is discovered to reduce cud chewing, PETA will be after us. Do you have any thoughts on how we can please the environmentalist without angering the animal rightists?

[looscnnn]

Um, what about all the animals that were around then? I didn't know that our ancestors were more efficient at clearing trees than we are, considering that we have more people. They would have had to clear a heck of a lot of trees to cause that.

[Monti Cello]

It's possible, but not entirely relevant to the 20th century CO2 increases, which have gone way beyond the levels seen in other interglacial periods with temperatures comparable to the present. The current level of CO2 in the atmosphere is abnormally high due to human activity.

What's disputed is the magnitude of warming attributable to CO2 increases.

[Question_Assumptions]

And just before this period, we have sheets of ice a mile thick covering all of North America. OK. I think I get it. The environweenies won't be happy until we are back in another ice age again. (This, by the way, was a plot element in a science fiction novel called Fallen Angels that dares to suggest that human activity might actually be keeping us out of the next ice aga.)

Hmmmm? Let me ruminate on that for a little bit. I'll get back to you.

[Lucky Dog]

Well, I am sure your reply will be intelectually well digested... certainly more than I can say for the article that started this thread.

[Fester Chugabrew]

Who was this guy, and did he change his underwear, too?

[richardtavor]

Thank G-d we're not on Mercury or Venus, where natural forces change the climate (besides that, just a little to warm for my taste!)
