Ice age data bolsters greenhouse gas, warming link

Well this is quite timely considering the argument jem and I are having......

WASHINGTON (AP) â The dramatic temperature increases that thawed the last ice age followed spikes in carbon dioxide levels in the air, a new study finds. Researchers say that further strengthens the scientific case explaining current man-made global warming.
In the new study, scientists show the atmospheric concentration of that heat-trapping greenhouse gas jumped more than 40 percent. Then global temperatures went up about 6 degrees Fahrenheit (3.5 degrees Celsius).
What is remarkable is that when the two are plotted they rise, plateau and rise again in a striking similar way with a slight lag. The warming over 6,000 years follows the greenhouse gas increase, just as scientific theory has long held.
This is important because, until this study, the two curves weren't quite so in sync. At some points, it seemed that the temperatures warmed before the carbon dioxide levels increased, something that climate skeptics seized upon.
How could carbon dioxide cause warming if the temperatures warmed first, argue skeptics, who are in the scientific minority.
Earlier studies had looked at carbon dioxide levels and temperature readings from Antarctica, not the entire world. A study published Wednesday in the journal Nature estimated global temperatures using 80 different proxies â ice and mud samples from dozens of places around the world â and found that globally, temperatures clearly went up only after carbon dioxide jumped.
"You end up with something that looks remarkably similar to the pattern of rising carbon dioxide through time," study lead author Jeremy Shankun of Harvard University said. "This, to me, seems like pretty powerful proof of theory of the connection between greenhouse gases and global warming."

jem? lol. he will take this sentence right here and say "see scientists agree with me" and dismiss every thing else in the article.
" At some points, it seemed that the temperatures warmed before the carbon dioxide levels increased"

This is true. He, and the other deniers here cannot even acknowledge CO2 is greenhouse gas because to do so would force them into cognitive dissonance. They will say "Look! A red herring!".

I'm presuming the usual suspects are responding with their usual stupid remarks. Thankfully I'm ignoring 377, Phoenix and denner because of the way they insult homosexuals and folks parents. Let me know if they say anything of value or substance. I doubt it.

How about sharing with us what greenhouses are used for?

Ya know, when ever I read about computer generated models of global warming I think of the rating agencies.

Computer generated models of credit worthiness.Computer generated models of "It's a good thing and I state my case".

At least I stopped comparing global warming to LTCM and the smartest guys in the room.

I'll defer to Buffet - beware of geeks bearing formula's.

Great points.Another danger with the global warming scam;
computer ''predictions'' can be frequently wrong. Especially predictions concerning the future of weather.

Now that they changed the name to ''climate change''

Wow, WSJ[Sat,SundayJUNE 3] reported in the sun shine state ''mild winter'';
vegtable prices changed/ proceeded to downtrend.Cool

And i would not call it ''global cooling'' even though thats what the media called it in the 1970's. Same WSJ arrticle noted the hard hit cherry crop. Problem was ''sucessive nights of hard freeze''.

None of this post is a prediction.Rich Dennis said ''exspect extremes''

The carbon taxes part.

Exactamundo! That ice was going to melt regardless of the tax rate, and the biggest polluters will continue to pollute regardless of any carbon tax rate. They'll just buy those Al Gore type credits and keep on keeping on, just like old Al will do himself. He won't cut back! He won't change his habits or lifestyle. That will fall on you and me, and there will be no change of any substance in the environment. And that's if you buy the whole man made only global warming argument in the first place.

In spite of imperfections (which you find with anything Man is doing) cap and trade does succeed. We have and need laws and their enforcement even if they won't eliminate all crime.

Yup. Times up. If we don't act now the earth and it's inhabitants are screwed.

Levels of CO2 in the arctic are now at 400 ppm and the ice is not doing too well.....

Oh btw, a key sentence in the article is this "One scientist even speculated that summer sea ice could be gone in five years."

One, as in only one, and he is a physicist not a climatologist or an oceanographer. And he is only one. One they write about because he says dramatic things. Because that sells magazines. The more reasonable estimates never get mentioned because they're boring.
