More news from the Global Warming front...

Carbon Cycle Feedback Significantly Less Than Thought

A new estimate of the feedback between temperature and atmospheric carbon dioxide (CO2) concentration has been derived from a comprehensive comparison of temperature and CO2 records spanning the past millennium. The result, which is based on more than 200,000 individual comparisons, implies that the amplification of current global warming by carbon-cycle feedback will be significantly less than recent work has suggested....

The authors derive a likely range for the feedback strength of 1.7-21.4 p.p.m.v. CO2 per degree Celsius, with a median value of 7.7. The researchers conclude that the recent estimates of 40 p.p.m.v. CO2 per degree Celsius can be excluded with 95% confidence, suggesting significantly less amplification of current warming.

That said, however, large epidemiological studies have established significant health risks associated with particulate pollution, and in my view the need to clean up our environment should not be lost sight of as the evidence for a Global Warming catastrophe continues to unravel. We can't just go back to sleep.

I’ve long maintained that a clean environment is reason enough not to pollute. There is no need for all of the Chicken Little global warming/climate change panic nonsense.

As if the climate changing were something new.

Funny, I watched a show last night on National Geographic about "global warming" and they used the word "could" probably 50 or 60 times in the hour long show! Also "might" and "if".
I "could" hit the lottery "if" I pick the right numbers or I "might" hit the lottery if I get lucky with a quickpick.

I have heard that the major culprit is China. How likely to gain their cooperation, do you think?

Obama even got laughed at when he claimed that the scientific evidence overwhelmingly supports AGW.

Fact is all these people are driven by money. Why don't we see these stats along with those that report our total contribution to CO2 in the first place ? Simple, eight billion or whatever, surface area of the Earth, volume of the atrmosphere and those degrees per PPM or whatever ?

If they could put all those stats together and represent them that way, they would make a good case, but they don't.

Now of course the argument could be made that industry emits more CO2, but what does that mean ? Give up all our industry ? That seems to be the main goal. That industry is going to exist somewhere in this atmosphere, no matter what. But the goal of the PTB seems that we become a nation of moneychangers and bullies to enforce it. That is the only possible conclusion I can draw at this time. I have no evidence of that directly except for the trends which should be obvious to all by now.

I have no evidence that the cite is true, none of us does, but look at any possible projected result. All against us. Why can't they correlate this data and present it truthfully and honestly, with numbers derived from real research ? If it was all that matters is to make their point, they really care and have the data to back it up, why wouldn't they present it.

I know why and you know why. There's more money in it this way.

Hi Kirata,

There's a new study too just published about the effect of water vapor in the stratosphere mitigating warming trends (the water changes a result of human activity, the effect a temporary constraint).

I didn't post it because I figured it would just be another round of the usual positions. But here...
