The BBC says:

Climate change may bring "abrupt and irreversible" impacts, the UN's climate advisory panel is set to announce.

Delegates to the Intergovernmental Panel on Climate Change (IPCC) agreed a summary of its landmark report during overnight negotiations here.

Discussions were said to have been robust, with the US and other delegations keen to moderate language.

The summary will be officially launched by UN secretary-general Ban Ki-moon on Saturday.

It brings together elements of the three reports that the Nobel Prize-winning IPCC has already released this year, on the science of climate change, impacts and adaptation, and options for mitigating the problem.

Among its top-line conclusions are that climate change is "unequivocal", that humankind's emissions of greenhouse gases are more than 90% likely to be the main cause, and that impacts can be reduced at reasonable cost.

Nothing new here. Almost nothing that humans can do to the planet is "irreversible" in any really meaningful sense of the word, but that is just political marketing spin. The only substantive claim that is controversial is that "impacts can be reduced at reasonable cost". The (rich) members of the IPCC will not be the people who pay this cost.
