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.

Yes is does. Climate's main thermostat is carbon dioxide, We know this from studying past climate on the earth, where CO2 level is the most important single factor in determining the earth's temperature. Richard Alley has said this in his YouTube lectures. I THINK this is one where he says it; if not, I'll keep looking & try to post it:[URL deleted]
No, climate doesn't have a thermostat:

A thermostat is a component of a control system which senses the temperature of a system so that the system's temperature is maintained near a desired setpoint. The thermostat does this by switching heating or cooling devices on or off, or regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. The name is derived from the Greek words thermos "hot" and statos "a standing".

You're lying because you've lost the argument. You WILL deny again.

Are you just lying repeatedly as deniers do? If not, swear that you'll never deny again.

I say your question is desperate stalling. You know damn well what the big, market-based measure should be. Why don't you tell us?

Coldest spring in 40 years in Minnesota, so much for "Global Warming", oh wait, they had to change it to "Climate Change", because it's so obviously BS!!!!!

Overall, winters have warmed about two to four degrees in the past 30 years or so. One good way to measure it is to look at these number of subzero lows that we're seeing at night. There are distinct trends that are emerging in the past 30 to 40 years toward fewer subzero low temperatures in Minnesota and the Twin Cities.

Quick example: this year we've had five days so far, last year we had three. That's a very low number. If you go back to the 1970s - the whole decade - we had 444 subzero days. During the 1980s we had 280, during the 1990s we had 256; down to 198 in the 2000s. That's a 57% drop in those subzero nights. If you look at that overall the trend lines show we could be down to around 10 on average per winter. We used to average about 30 back in the '70s and we could be maybe closer to zero by 2040. By 2040, in the Twin Cities we could be very close to few or any subzero nights if our current climate trends continue.

Frank Luntz, advisor to re-pubic-lick-uns, said to use 'climate change' to make re-pubic-lick-uns more electable. However, re-pubic-lick-un numbers continue to decrease percentage-wise.

As for your cold weather, AGW enhanced warm fronts push hard into the Arctic, causing some of the Arctic increased temperatures. Simultaneously, Arctic cold fronts are moved out of the Arctic to the south, giving you cold toes. I'm glad.

You've read my accounts before. You just continue to deny the truth.

Yes, climate DOES have a thermostat, & it's carbon dioxide. But don't take my word for it. I finally found the correct Richard Alley video:

http://www.agu.org/meetings/fm09/lectures/lec...

CO2 does exactly what you say a thermostat should do. If you have an open mind, watch Alley's vid. He's a bit goofy & nerdy, but entertaining & informative.

Currently, humans are emitting CO2 into the atmosphere ~20,000 times faster than natural processes emit it. We are already seeing anthropogenic climate, & will see ever more of it in the future.

Scientific facts are true no matter how many times you try to say they're not.

It would be more correct to say that CO2 (and other GHGs) are the PRIMARY thermostat. Other factors can produce a smaller shift that may confuse some people trying to isolate the cause and effect.

The issue of the thermostat is one of insolation (incoming heat from the sun) which is fairly but not entirely constant, balanced against the necessary surface temperature to drive the SAME amount of thermal IR radiation to space. The barriers to this IR are GHGs which retard IR photons. On the incoming side, we have SMALL changes in the solar output, along with some effect from high altitude sulfate aerosols which can reflect some solar influx.

All else is 'shifting heat around' which is the CLIMATE response, not AGW. Of course, the primary problem of AGW is the climate response so we cannot lose sight of the fact that AGW will tamper with the climate in many ways, from floods and drought to record cold and warm spells. In fact, the primary effect of AGW will be to make it easier for record events to occur.

Retarded denier argument #1 yet again! Denier BS never dies because deniers are immune to refutation and impressed with childishly fallacious arguments.

I believe that it's Ellesmere Island that has warmed 10.7 degF in mid-winter. Such data are harder to deny than fractions. Too bad scientists don't have a megaphone to disperse such facts as efficiently as the denial movement disperses misinformation.

Sorry about that previous response. You didn't quote the comment to which you were responding and, you must admit, your comment reads just like some of the denier stuff.

Yes, of course. I was oversimplifying a bit because some here don't appear able to appreciate nuance or complexity. There are many factors that affect temperature besides CO2; it's just the main one.

Just the mechanism of radiative forcing appears beyond the grasp of some here. It's not the same as conduction, but some here can't understand that.("The cooler atmosphere CAN'T warm the earth! It violate the 2LOT!" Crazy.)

None of you know what youre talking about. its not "global warming"
anyone considered the bible?
God said in the world's end time you will see signs in the weather.
"For nation will rise against nation, and kingdom against kingdom, and in various places there will be famines and earthquakes" Matthew 24:7
"And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet."
The book of Matthew 24 is very good at explaing whats going on and soon to come, signs right in front of our eys. notice how crazy the weather is and recently? how can that be global warming? maybe that could be what's fulfilling these prophecies, even how the government is spraying the sky so much. wake up and see

Even if all the "climate change scientists" in the world told you idiots straight to your face GW is a hoax, the gloom and doomer imbeciles, like yourself, would still argue GW exists, liberal idiots like you would just find somebody else to say what you want to hear.
