"We started to accept two or one and a half degrees in the pre-industrial era.
"But at the current 0.8 degree warming, the North Pole is melting.
"Assumptions about how much temperature can be added to Earth's system were unacceptable.
"This is not what we can tolerate as a positive outlook. On the North Pole … it stores large amounts of methane.
– They have not melted yet; we have the chance to keep the most frozen.
"This is a huge existential challenge … [akin to] a comet to the earth. "
He said that modeling has shown the worst scenarios – a small, but realistic risk – that the Earth loses its own temperature control through biological processes, which up to 250 degrees Celsius and most of its carbon dioxide atmosphere can not support the planet human life.

The world now has a carbon dioxide threshold of 410 million ppm in the atmosphere. The last time the world was 350ppm was in 1988. The goal was now 280ppm.
The world had to reduce emissions by 150 percent and the 2050 was too far from the target.
"Only in 2049 people would be worried," he said.
"By 2020 we reach the peak of emissions … this is a big challenge today to start – or yesterday.
Professor Droege says this is feasible, but only 100% renewable energy in the system around the world.
This was all possible and economically understandable, but the promotion of politics came in unpredictable global waves. At present, subsidies have slowed down and no country has reached the Paris targets (in fact, a recent report by a German researcher has shown that if the WA government approves the gas fraction and deceives all the potentially unconventional gas stocks in WA, this is Australia's carbon footprint would blow up its budget three times under the Paris Agreement).
"This problem can only be solved in a democratic manner by voting," said Professor Droege.
"What we need, the innovation drive must be released at all levels."
Professor Droege describes places throughout Europe that have undergone radical changes and modernized the existing urban areas on a large scale.
The city of Berlin was 100% renewable. In Spain, a whole bioregion has switched to 100% wind farms in just 10 years. Frankfurt and Munich launched city-centric renewable neighborhood programs. Paris and New York have developed similar programs. Freiburg, Germany, has jointly operated a social housing project with its own joint fleet.

The Rocky Mountain Institute of the US has proposed a business model to renew the entire districts through new technologies and efficiency gains. The Kalkbreite co-op built in prefabricated panels has created a communal communal living space with commercial and public spaces in a tram-filled district.
A seven-year workout in Hamburg, on the largest river island in Europe, saw a solar-rebuilt area, an alga-enclosed building that could be used for bio-energy producing biogas from grass and human waste, and an old Nazi A bunker operated as a solar storage tank neighborhood
The designers' GIS model has shown that by 2030 it has a 100% renewable energy source with a zero emission number.
It is indispensable that all projects are entrusted to a competitive process and builders' partnership.
"This business model allows these projects … the assurance of return," said Dofee PRofeesor.
"Business models need to be propagated.
"This should be the standard for the new development.
"Energy is everywhere, an opportunity to look at the city as an energy landscape."
The future is elsewhere.
However, despite ambitious plans to increase renewable energy sources, Germany's energy resources have been renewed by only 30%. There was still 40 percent of carbon in the blend and atomic energy.
Germany began talking about discussing the future of a coal-fired power plant (similar to WA Collie's stations), holding consultations to formulate when it comes to the life of the 45-year-old mine.
"Instead of" where did the coal come from, you bastards? "There have been members of the coal community, local residents, environmental groups, all of whom have been thinking about how the landscape looks at, how to make a carbon isolation option," he said.
According to Professor Droege, the Australian cooperative research was beyond the purest research.
Renewable technologies have exponentially developed and peaked at the global level, but the incumbent industries and interests have been withheld.
"We are creating a world of incubators that bring technology to market, but we need more than markets, we need governments to get rid of and open up the arcades to innovation," he said.
"Cultural transformation can only be raised from the bottom, but leaders need to know the basics.
– The future is somewhere else.
