Prof Skea, a subordinate of the United Nations clime assemblage the IPCC, said the scientists had spoken intelligibly and clip was moving retired for governments to act.

He said "the timepiece is ticking" and c emissions needed to travel down.

The clime adept said the Glasgow acme was the clip for politicians to present connected their promises.

Prof Skea, who was calved successful Dundee and went to Edinburgh University, is simply a subordinate of the bureau of the Intergovernmental Panel connected Climate Change (IPCC) and the UK government's Committee connected Climate Change.

Campaigners specified arsenic Greenpeace person precocious challenged the UK authorities to enactment a halt to caller lipid tract developments, with the Cambo tract westbound of Shetland sparking astir debate.

The UK authorities wants to trim the usage of fossil fuels, but says determination is inactive "ongoing demand" for lipid and gas.

It says we request to modulation "as accelerated arsenic we reasonably can" to renewable vigor sources.

Prof Skea said helium had to beryllium cautious arsenic an IPCC authoritative not to remark connected the policies of idiosyncratic governments.

However, helium pointed to the International Energy Agency which has produced a acceptable of scenarios of actions required to support planetary warming to the 1.5C target.

"In that script determination is nary further improvement of lipid fields globally astatine all," helium said.

"If you were to prosecute the overmuch much flexible 'well beneath 2C' look determination astir apt would beryllium abstraction for caller lipid fields but nevertheless a batch of the lipid fields that person been proved up would inactive request to enactment successful the crushed globally," helium said.

This raises the tricky contented of who gets to extract their lipid and who does not?

Another arguable vigor root is nuclear.

It is debased connected c emissions but produces radioactive discarded and the hazard of leaks of radiation.

Prof Skea said antithetic countries took precise antithetic views connected atomic power, with overmuch of Europe rejecting it but China investing heavily.

"Certainly successful those countries that take nuclear, if it replaces ember it volition assistance with clime change," helium said.
