Temperatures are expected to rise this century largely due to man-made global warming, a major UN report is to suggest.
UN scientists are expected to say they are 95% sure humans are responsible for climate change in key report to be published today. The findings are expected to show:
- Temperatures will rise by between 0.3C (0.5F) and 4.8C (8.6F) this century
- The lower end of the range will only be possible with emissions cuts deeper than anything that major economies have said they are prepared to tolerate
- Almost 200 governments have agreed in principle to limit global warming to a maximum rise of 2C (3.6F) above pre-industrial times
- The governments have promised to work out a UN deal to limit their emissions accordingly by the end of 2015.
