Noticed this article on the register http://www.theregister.co.uk/2012/01/16/criegee_biradicals/, looks like another self regulating, climate mechanism that could reduce the FUD factor.

First few paragraphs-

Chris Williams for the Register wrote:
Elusive pollution-busting molecules are scrubbing our planet's atmosphere at a much faster rate than first imagined, according to gas-bothering boffins.

Reactions by the cleaning agents, known as Criegee intermediates, are also emitting a by-product that forms solar radiation-reflecting clouds that could help cool Earth and reduce the effects of global warming.

The Criegee biradicals were first hypothesised in the 1950s by German chemist Rudolf Criegee, but only now have they been recreated in a lab and directly measured for the first time. Specifically, the scientists took formaldehyde oxide – a species of Creigee intermediate – and observed it reacting with sulphur dioxide and nitrogen dioxide.

These dioxides are said to initiate climate change in our atmosphere, yet it's now understood they are removed from the troposphere by helpful Criegee biradicals – described as pivotal atmospheric reactants. The reaction also spews sulphate and nitrate into the atmosphere, creating aerosol droplets that seed planet-cooling clouds.

The rate of compound conversion is much higher than the boffins expected, leading them to conclude that the biradicals may have a greater impact on our climate than previously thought. The production of Earth's short-lived Criegee biradical stocks are fuelled by the combination of ozone and chemicals released naturally by plants.

There was a program about global warming , and the earths ability to regulate the CO2 content of the planet . It was stated that chalk seams ( as in the Cliffs of Dover etc) acted as storage facilities foor CO2- regulating the amount in the atmosphere to regulate the temperature . To me seemed to knock a large hole in the C02 theory . Too much C02- the chalk seams soaked it up - and released it back if the concentration dropped .

I don't think that anyone denies that natural mechanisms for regulating the CO2 content of the atmosphere exist. The question is whether they can cope with the amount of CO2 released by human activity in the 21st century.

Wrong!

The question is, should we spend tens of trillions or more to try to prevent something that may be happening according to models that so far have proved to be incredibly inaccurate (e.g. lack of warming for the last ten years, no sea level rise, lots of ice in the Arctic, happy polar bears etc.).

Now you are talking about US defence policy :D

But, seriously, aren't we allowed more than one question?

Interesting article in the Spectator (reprinted in Wetherspoon news) - "Truth about Sea Levels"

The real question is why we are so worried right now when historical records show we had 10-20 times more atmospheric CO2 than today, yet the global temperatures were the same (or lower due to the ice ages).

Given this, it seems to me that everything else becomes rather moot.

This program suggested that the capacity to cope with various amounts of CO2 was regarded as being more than sufficient ,and that queations as above were from persons not acuainted with the performance of nature .

Reference please

Upon digging, I have to admit to making some sort of error here.
To correct my earlier claim: historical records show we had 10-20 times more atmospheric CO2 than today, yet the global temperatures, at times, had been the same.

http://ff.org/centers/csspp/library/co2 ... ioxide.htm (the original sources are provided within the link).

IMhonestO, it is clear there is no conclusive direct causal effect, from CO2 level to temperature. There probably is an 'undiscovered' (!) causal factor that affects both CO2 and temp.
Let's not forget that it has not been explained why today's global temperatures are not following the much vaunted climate models.

I think it most interesting that the magnetic North is slowly changing and thoughts are that it will 'flip' and Nth will be South, & South North (in about 800 yrs time). Satellites already have to avoid a huge area around Sth America as it messes up the equipment, and there are many pockets around it too !
I wonder then if that is what changes the Jet stream and then that has the final climatic change to the 'ice age' ending and begin the 'hot age' or whatever it is/will be called. Surely the jet stream which they have no idea how it got started (has it 'always existed' does it/ did it, ever) so ow do we know all those effects on the weather and the consequences thereof. Although we do know that our area (UK) is 'warmer' due to it's existence.

It is (on a planetary scale) all most interesting, as it shows just how little we really know about how are planet works!

Global warming is going out of fashion pretty rapidly, in a few years collective embarrassment will erase it from history.

Labour is lurching left again so the left can dispense with the green cover and resume the class war god a while, who cares about carbon and patio heaters when we have bankers to bash?

... for this generation.

I'm sure it will eventually rear its ugly head again in not too long (i.e. the media frenzy that was "global cooling" ...)

There'll be some apolcalypse brought about by the greed of man I'm sure.

We've had global cooling, warming, acid rain.....maybe the next thing will be global mildness. Temperate and pleasant conditions brought about by man's continued rape of the planet. Something must be done.

Out of interest -- not argumentativeness :-) -- how are historic CO2 levels measured?

I believe they look at the bubbles of trapped air in Antarctic ice core samples.

It is "proxy data", because they are not directly sampling the air at the (estimated time), and i am sure that the margins for error must be considerable. Nevertheless, it is used a a big stick to tell us to reduce (and bury) our carbons :(

The problem is not the current CO2 level.
The problem is: ##is the current CO2 level leading to climate change or is climate change causing higher [atmospheric] CO2 levels##
And:
Is a higher CO2 level sufficient, or is it possible, to cause runaway warming ?
IE: Is any feedback positive or negative.
The "warmists" say it is and that feedback is positive....however, they also said that clouds caused positive feedback.
The "skeptics" say it isn't.
Both sides admit that CO2 "traps" heat, one side says it is going to get worse, the other says it isn't, not by much.
CO2 has been much higher in the DISTANT past Image
(500 million to 3 million years)
but not in the recent past Image (half a million years)
The problem is compounded by the intense political/financial establishment on the "warmists" side, which means that if (highly likely) they are wrong the financial cost, so far, of nearly one trillion dollars, will mean they will be lucky to avoid being lynched.
Since even stupid turkeys do not willingly vote for Christmas we (I) cannot expect scientists to vote for personal poverty.
And there lies the REAL problem....the subject is too personal to have an easy, or fast, resolution.
So, roll-on the "renewables" and power cuts......don't expect "fracking" to bring you cheap gas, because they are finding in the states that while it is cheap...it is too cheap.....there is not enough profit to provide funding for the required [future] research and planning, let along production.
AND this government has already said it will be sold to export.
Since they insist that the sun has no effect on climate change (apart from the problem of no sun = no climate) and that their models are right (part of the trillion....loads of super-computers) when they cannot even forecast the past given the present as an input ?
