Climate summit week: what lies ahead?

It is UN climate summit week and negotiators have for the last five days been thrashing out the details of an historic deal to limit global warming to under 1.5C.

Consensus has emerged on the ambitious goals in the draft deal for countries to aim for a range of temperature rises of 2C-3C above pre-industrial levels – well below the 4C “dangerous” global warming goal adopted in the Bali plan to stave off cataclysmic climate change.

There is also agreement in broad outline on limiting deforestation, and reducing the huge carbon emissions from aviation and shipping.

Scientists say the cuts are essential if the world is to avoid at the very least catastrophic climate change, and potentially climate chaos.

The negotiations in Bonn are part of UN talks that will continue until 12 November in Poland.

Both major parties have agreed on the basic goals but there are gaps over the finer details.

The US has the strongest objection to much of what the other sides have agreed on, arguing that it violates trade rules.

Although the Bush administration has a single offer in the draft deal, backed by Russia, it appears that the European Union and China have countered with their own separate offers of about half the emissions cuts demanded by the US.

The EU and China have been threatening to walk out of the talks if the US position remains so uncompromising.
