Climate scientists will today attempt to shore up flagging public confidence in measures to control greenhouse gases, with a crucial assessment of global warming.
The International Panel of Climate Change (IPCC) is expected to warn that it is now 95% certain that global temperatures are rising and that human activity is to blame.
It says carbon dioxide levels in the atmosphere will rise to double pre-industrial concentrations by the middle of this century, and that will result in a global temperature rise of between 1.5C (34.7F) and 4.5C (40.1F).
