A climate target accepted by the United Nations was to limit temperature increases to two degrees C. Yet the last 10 years has seen a rapid growth in global emissions.
This rise, together with the lack of a comprehensive global agreement, has meant that the target is now unachievable. The world economy will continue to grow. Achieving the two degree target depended on attaining greater and greater efficiency, and lower and lower carbon intensity. But the continuing reliance on fossil fuels to power economies makes such a low carbon world a dream. The chart below compares the progress being made to curb greenhouse gases with what is needed to limit temperature increase to two degrees C.
There would need to be a limitation on the carbon dioxide equivalent CO 2 e concentration in the atmosphere to parts per million.
Predictions are subject to uncertainties. The new policies will likely limit temperature increase to between three and four degrees C. This is a rise that will profoundly change the world as we know it. Most of the abatement is through the purchase of million tonnes of carbon offsets from overseas — rather than by domestic action.
