Climate Change BOMB is one-degree-Centigrade away

A climate tipping point of 1.5 °C above pre-industrial levels has been discovered. Detailed studies of stalactites and stalagmites in caves in Russia's Lake Baikal region revealed that Siberian permafrost is perilously close to the melting point. A store of carbon twice the size of the atmosphere's will be destabilized if temperatures rise 1.5°C from pre-industrial levels according to a report published on line today in the prestigious Journal Science.
The report's chillingly understated final paragraph reveals that permafrost degradation begins at a temperature of 0.5°C above pre-industrial levels. The climate has already warmed 0.5°C. Massive degradation begins at warming above 1.5°C, which is half a degree below the IPCC's target for warming. The results of this study indicate that the new target must be 1.5 °C if we intend to keep warming from going well above 2°C. 2°C is not a stable target. It is past the permafrost "tipping point" of 1.5°C.
