Found a molecule that can freeze the planet

A molecule that can cause global cooling, is called "intermediate Krige," her missing for 62 years, since in 1949, the year of its existence suspected German physicistRudolph Krige, but until yesterday it continued to be elusive. Yesterday, the journal Science reported that the hunt for this bit of a success. Experts have called it the opening of a revolutionary breakthrough in the understanding of global climate change.

Intermediate — an intermediate product of a complex chain of chemical reactions, in this — in the atmosphere when exposed to light in the formation of ozone. Krige suggested that his potential intermediates are powerful oxidants such air pollutants as nitrogen dioxide and sulfur dioxide. But it all depended on how quickly these molecules are formed and how long they live.

A group of British researchers from the Universities of Manchester and Bristol, together with scientists from Sandia National Laboratories (USA) managed to get to the mysterious molecules using synchrotron third generation American. Scientists from Sandia created a unique apparatus that transformed into a source of synchrotron powerful and, most importantly, the controlled, the photon beam optical range — that was exactly what was lacking former hunters intermediates Krige. When using synchrotron scientists were able to identify one of the intermediates Krige, the properties of this molecule has surpassed all expectations.

Its rate of formation was much higher than previously thought. This means that the molecule has time during its lifetime to form sulfates and nitrates, which are then assembled into aerosols, and they, in turn, can form clouds that reflect sunlight and slow down global warming. However, intermediate Krige was so active that scientists believe it will slow down the warming, but in the future and cause global cooling. Like it or not, will show further research intermediates Krige.
