tailieunhanh - Climate Safety

The annual summer warming of the Arctic in 2008 was watched closely by an army of expert observers and other interested parties around the world. Organisations such as the US National Oceanic and Atmospheric Administration (NOAA)3 published neardaily updates on the state of the Arctic sea ice, which every year recedes from its winter maximum as the summer comes to the far north. The reason for this scrutiny was the record low level of Arctic sea ice extent observed in summer 2007, when an area of ice nearly the size of Alaska melted. The modern Arctic is a very different place to the Arctic of the past | climatesafety In case of emergency.

The first is that climate change is accelerating more rapidly and dangerously that most of us in the scientific community had expected or that the IPCC in its 2007 Report presented. The second is that because political inaction has delayed progress for so long the imperative for extremely urgent action on both national and global scales is now paramount. The target that has been broadly accepted by many bodies including our own Government is that a rise in global average temperature of more than 2 C above its preindustrial value must not be allowed. To achieve this deforestation must be halted within a decade or two at most and serious decarbonization of the energy sector must begin immediately. Can the necessary reductions be achieved No less a body than the International Energy Agency has just reported WEO .
