Offsetting Global Warming: Molecule in Earth's Atmosphere Could 'Cool the Planet'
ScienceDaily ^ | Jan. 12, 2012 | NA

Scientists have shown that a newly discovered molecule in Earth's atmosphere has the potential to play a significant role in off-setting global warming by cooling the planet.

In a breakthrough paper published in Science, researchers from The University of Manchester, The University of Bristol and Sandia National Laboratories report the potentially revolutionary effects of Criegee biradicals.

These invisible chemical intermediates are powerful oxidisers of pollutants such as nitrogen dioxide and sulfur dioxide, produced by combustion, and can naturally clean up the atmosphere.

Although these chemical intermediates were hypothesised in the 1950s, it is only now that they have been detected. Scientists now believe that, with further research, these species could play a major role in off-setting climate change.

The detection of the Criegee biradical and measurement of how fast it reacts was made possible by a unique apparatus, designed by Sandia researchers, that uses light from a third-generation synchrotron facility, at the Lawrence Berkeley National Laboratory's Advanced Light Source.

The intense, tunable light from the synchrotron allowed researchers to discern the formation and removal of different isomeric species -- molecules that contain the same atoms but arranged in different combinations.

The researchers found that the Criegee biradicals react more rapidly than first thought and will accelerate the formation of sulphate and nitrate in the atmosphere. These compounds will lead to aerosol formation and ultimately to cloud formation with the potential to cool the planet.

The formation of Criegee biradicals was first postulated by Rudolf Criegee in the 1950s. However, despite their importance, it has not been possible to directly study these important species in the laboratory.

In the last 100 years, Earth's average surface temperature increased by about 0.8 °C with about two thirds of the increase occurring over just the last three decades...

“The University of Bristol and Sandia National Laboratories report the potentially revolutionary effects of bi-radicals.”

According to Larry Sinclair, we have one of those in the White House right this minute....

There's lots of iodine in the oceans, so this stuff is surely getting kicked up into the air constantly. What do they call CH2I anyhow? Iodoform?

God even put it there in the first place! God is sometimes described as wise, which means not just what humans think of as wisdom (showing patience, kindness, etc.) but an ingenuity and planning more intense than any number of human brains could embrace. Whatever, say, Thomas A. Edison invented, God already had planned to come into existence.

I think you can call CH2I iodomethylene, but I'm not sure if that's International Union of Pure and Applied Chemistry, IUPAC, name. Iodoform is CHI3.

Interesting...is there a double bond with the iodine (carbon is normally tetravalent)? And is it trigonal planar?

Full disclosure: NIST says it is a cation, and the structure is unspecified...cool!

Cheers!

Except it isn't a methylene any more with that trivalent carbon. But I can't find any CH3 either to be the basis of an iodo-something. I wonder if that is actually a radical lacking another hydrogen it would have as a stable compound and there isn't any CH2 molecule.

I mean, no CH2I molecule.

That would make it an iodomethyl radical... right?
