Researchers claim a newly discovered molecule found in the Earth's atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.

Criegee biradicals are carbonyl oxides that were first hypothesized in the 1950s by Rudolf Criegee but had not been able to be directly detected until now. Using a unique apparatus designed by Sandia Lab researchers, researchers from the University of Manchester, Bristol University and Sandia Labs were able to detect the Criegee biradical - in this case formaldehyde oxide (CH2OO) - and measure how fast it reacts.

The apparatus used the intense, tunable light from a third-generation synchrotron facility at the Lawrence Berkeley National Laboratory's Advanced Light Source to discern the formation and removal of different isomeric species, which are molecules that contain the same toms but arranged in different combinations.

The researchers found that Criegee biradicals react much faster than initially thought and will accelerate the formation of sulfate and nitrate from sulfur dioxide and nitrogen dioxide in the atmosphere. They say that these compounds will lead to aerosol formation and ultimately cloud formation, which has the potential to cool the planet.

"Our results will have a significant impact on our understanding of the oxidizing capacity of the atmosphere and have wide ranging implications for pollution and climate change," said Dr Carl Percival, Reader in Atmospheric Chemistry at The University of Manchester and one of the authors of the paper. "The main source of these Criegee biradicals does not depend on sunlight and so these processes take place throughout the day and night."

"A significant ingredient required for the production of these Criegee biradicals comes from chemicals released quite naturally by plants, so natural ecosystems could be playing a significant role in off-setting warming," added Professor Dudley Shallcross, Professor in Atmospheric Chemistry at The University of Bristol.

The researcher team's paper, which is published in Science, describes a new means of producing gas-phage Criegee intermediaries, which they used to prepare enough CH2OO to allow measurements of its reactions with water, sulfur dioxide, nitric oxide and nitrogen dioxide. It is this ability to reliably produce Criegee intermediaries that the team says will facilitate future research that could allow these molecules to play a major role in off-setting climate change.

Hopeful that something useful (in a non explosive way) can come from these projects.

won\'t these clouds full of pollutants cause acid rain all over again

I wonder if these chemicals or a derivative can be used to clear the air of smog or heat inversion problems? Imagine a crop duster plane flying around LA and a path of clear air behind.

OK sci-fi fans. Imagine 20 years into the future. An \"eco-bomb\" has been theorized and built by a European organization, a clandestine division of Green Peace. This bomb, called the Criegee intermediary broadcast device is capable of being detonated over a major city and, in theory, cause a mass restructuring of the pollutants and render a clean and cooler enviornment. The only problem is that no one is willing to chance the possibility that, as a result of the release of such a great quantity of the Criegee biradicals, a power struggle would be created between the corporations that now no longer need to clean and scrub their waste and the enviornmentalists who, by now have the upper hand. It gets better, but you get the idea, huh?

That\'s a great idea! If a little bit can cool and clean the climate, just imagine what a bunch can do. Dang the global warming, soon we\'ll be back to talking about the coming Ice Age. Sometimes I wonder if those 50\'s sience fiction movies didn\'t have it right in the first place.

First we have to think what if the planet is not warming? Should we help the Planet? Or just leave her alone!!!! Who Should be the one making the Choices a handful of science majors and a politician? Or The Worlds Population? We must think!

This is the most unbelievable audacity - to think that man needs to control planetary climate. You\'d be doing better to develop something that would allow mankind to more easily adapt to the naturally repetitive and cyclic climate changes of the Planet rather than changing the Planet to unnaturally suit mankind. I also think you need to check historical climate patterns before you talk about global warming. Based on historical EVIDENCE that tracks the cycles of climate change, the Planet is entering a cold-phase as a result of the shift of the magnetic pole. I suggest your research includes The 1844 edition of The New York Dissector, Vol 2. ppg 379-383 that discusses historic changes of temperatures in Greenland relative to the shifting magnetic poles. This scientific and historically accurate document exposes the current Gore-inspired \'Global warming\' scam for what it is - a scam. PLEASE stop trying to double-guess Nature.

The discovery is very interesting, I wonder if they could test the output of the HH2 Hydrogen Clean Air Combustion System as the HH2 cleans up toxic exhaust emission inside the engine during combustion. California smog tests show reductions of Carbon Monoxide, reductions Nox up to 98%+ and several other gases are lowered or eliminated. The HH2 system has been installed here in many locations in the USA and results are reported by clients of significant reductions in toxic exhaust emissions across the board. The HH2 system disassociates the Hydrogen and Oxygen molecules from water in a sealed system the creates each gas completely separate from the other using only 12-14 volts from a vehicle battery connection. Amps vary from 5 to 15 amps during operation and the power draw is consistent as it works only when the engine ignition circuit is running. To date every installation has reduced toxic exhaust emissions on ALL vehicle the HH2 system has been properly installed. Client results and names available by request to valid entities upon signing a NDA prior to release of any info. I am curious if some of the discovered Criegee intermediaries are being created via our system. Website: www.HH2.US Comments???

These are some of the most dangerously stupid men I have ever heard of, absolutely frightening with no understanding of the climate changes involved. They would start an ice age and do what many want, that is kill most of the population. There is no global warming, there is solar system warming as we have moved into a new area of space and all the planets in the solar system are heating up not just earth, futher it is a temporary condition. This is not the first civilization on this planet and we have to stop "GUERILLA ENGINEERING". I have seen this kind of work before, to be kind, I am underwhelmed, this is a political population reduction agenda, not a scientific agenda. Shame. Even when the science outs this garbage agenda, even when the Britts get caught falsifying data, and who is involve again, the Britts, we still see this prpaganda, why is that? I cannot prove it, but I believe someone is patting idiots on the head for provding a hard to prove path to mass murder. Sandia: providing idiots to the absolutely corrupt, all they need is a new logo. How about a jackass, no the dems got that, hmmm... R. Dunn

Criegee biradicals seem to increase air pollution, enlarge the ozon hole and make non watery clouds,a disaster not an improvement.
