Economics of climate change

Governments and academics are deeply divided over the economic costs and benefits of combating climate change and moving towards a low-carbon economy. The Stern Review, an influential enquiry into the issue, concluded in 2006 that fighting global warming would cost 1% of global GDP, while non-action could lead to a 20% loss of GDP in the long term. In comparison, research published in January 2009 shows that avoiding dangerous climate change could cost as little as 0.5% of global GDP.

Science of climate change

The scientific consensus that humans are responsible for global warming is now compelling with over 90% probability, according to the latest conclusions from the Intergovernmental Panel on Climate Change (IPCC), a UN-backed scientific body. But uncertainties remain surrounding the extent of future temperature rises and the effects they will have on the earth’s complex ecosystem.
