TAKE ACTION NOW TO PREVENT 4°C RISE (IPCC)
Global warming can still be limited to 2°C in 2100, but only if action is taken now to cut energy use and decarbonise electricity, say scientists. In the third part of the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report, scientists argue that it remains possible and cost-effective to reduce global emissions of greenhouse gases (GHGs) to levels that are likely to limit temperature rise to 2°C at the end of the century.
