Global warming 'undeniable,' scientists say

Full story: TwinCities.com

Scientists from around the world are providing even more evidence of global warming, one day after President Barack Obama renewed his call for climate legislation.

Since 1997 the planet (or at least the U.S. portion of it) has been cooling! Just like Murphy said in his column. And this cooling is not just a 2009 phenomenon.

If you input 1996-2010, the temperature is flat-lined, so the cooling started at least in 1997 in the U.S., and almost certainly everywhere else as well. And, the later you put the end date, the more pronounced is the downward, cooling slant of the temperature line.

The incas/myans/celts/neandertols/ barbara bush called it an "earth cycle" or "warming period" or "ice age" god these guys are genious.

Did you read the last sentence in the paragraph? If not, you should.

Climate changes all the time. The question is whether or not the amount of CO2 made by man thru the burning of fossil fuels can/will/has changed climate.

And basically neither side can PROVE whether the amount of CO2 made by man can/will/has changed climate for one apparently ignored reason.

We DON'T have records going back far enough. The Earth is BILLIONS of years old. I'm sorry if it damages some peoples' ego but human history isn't even a drop in the bucket when compared to geological time. It's microscopic. All we really know is that the Earth has gone through warming and cooling cycles (whether or not there is a patten as to how much time passes before a major change is not completely known) and has switched magnetic poles.

The evidence of this is held within rock segments. But even there, there is a problem because it is impossible to look at segments of the earth from the earliest due to plate tectonics. Those earliest segments were subducted (forced beneath the continental and or ocean plates back into the core of the planet) and melted billions of years ago.

So the only thing that could be proven is that the earth is getting warmer in this period of human history -- NOT precisely what is causing it. So I think that our time would be better spent in researching ways to ADAPT to this change before coastal cities are inundated. Mammals have survived previous climatic changes precisely because they have a far greater ability to adapt to change than the reptiles did.

Yeah, let's all agree to get rid of that nasty CO2 stuff!

Let's legislate it out of existence!!!

We need to measure temps for billions of years and wait for the result!

Plus, Al Gore wants to suck all CO2 out of existence! It's true! I have a thorough understanding of climate change theory!

The "warming" isn't being caused by man...

Man-made CO2 isn't physically capable of absorbing much more than
two-thousandths of the radiated heat (IR) passing upward through the atmosphere.

And, if all of the available heat in that spectrum is indeed being captured by the current CO2 levels before leaving the atmosphere, then adding more CO2 to the atmosphere won't matter a bit.

In short, the laws of physics don't allow CO2 it's currently assumed place as a significant "greenhouse gas" based on present concentrations. The other "greenhouse gases" such as methane, nitrous oxide, tetrafluoromethane, hexafluoroethane, sulfur hexafluoride, trifluoromethane, 1,1,1,2-tetrafluoroethane, and 1,1-difluoroethane exist only in extraordinarily smaller amounts and aren't even up for serious discussion by any segment of the scientific community. And, since the other components of the atmosphere (oxygen, nitrogen, and water vapor) aren't materially affected by human activity, the "greenhouse effect" is essentially a totally natural phenomenon, unaffected by human activity. We could repeat the spectral analysis and calculations for Oxygen, or O2 ( The percentage of oxygen in the atmosphere remains exactly the same at all heights up to about 85 km, and is about 20.9% by volume ) and Nitrogen (N2) which is the whopper at 78.1%- but we won't. Just look up the atomic absorption spectra for both, and do the math. You'll discover that Oxygen and Nitrogen aren't even "greenhouse gases", so that leaves the principal greenhouse gas... you guessed it.... Water Vapor. Curiously enough, the UN IPCC reports don't even mention water vapor, since it is technically not a "gas" in the atmosphere.

It can safely be ball parked that water vapor as being responsible for more than 95% of all the greenhouse effect, with oxygen and nitrogen playing no role and carbon dioxide being relatively insignificant... particularly the even smaller human-produced part.

Are they still basing the evidence on false data from Russia?

Since we can no longer believe the lib scientists on this issue their word is worthless.

Wow! I guess timing is everything. And I thought they changed it to "climate change" to, you know, cover ALL the bases.
Yes isn't that amazing timing
like the last time....
he announced he was going to open up offshore drilling off the coast of Virginia, the next day the gulf oil disaster occured.
It makes you wonder why Obama then said he was sending 33 SWAT teams to the gulf to inspect oil rigs.
Something just doesn't sound kosher about that.

Hey, you're right! Obama blew up the rig!

90 degree day.....they must have been a first.(sarcasm)

C'mon you peabrain even you liberals claim you can't judge the climate based upon one day.

We set one cold record after another this past winter.....

For hundreds of years people have claimed the planet was under a crisis and doomed, each and every time it has been a false alarm.

The sky is not falling all is well.

Intelligent, well worded, common sense posts like yours, have no place on a forum where even the scientifically minded, alarmist posters prefer to insult and belittle their adversaries, in preference to proving their case.
But you have my congratulations for making a brave attempt to point out the obvious.
