The present approach to climate change isn’t working

Bjorn Lomborg
The present approach to climate change isn’t working. If fully implemented, analysis of the leading climate-economic models shows that the Paris Agreement will cost $US1 trillion to $US2 trillion every year in slowed economic growth. Our response to climate change is so expensive because alternative energy sources remain expensive and inefficient in most scenarios. It is still very expensive to switch from fossil fuels — hence the fortune being spent on subsidies, to little overall effect.  ........Despite costing a fortune, the Paris Agreement will have virtually no impact on global temperatures. The UN Framework Convention on Climate Change has estimated that even if every country makes every single carbon cut suggested in the Paris treaty to the fullest extent, CO2 emissions would be cut by only 1 per cent of what would be needed to keep temperature rises under 2C. Incurring an annual $US1 trillion cost while failing to rein in temperature rises is a very poor idea."
