"We need to halve greenhouse gas emissions globally by 2030 and cut coal use by two-thirds by the same date".
The report says the rate of warming caused by human activities is speeding up and that global emissions would need to fall by 45% by 2030 - twice as fast as previously envisaged.
The signatories of the Paris Agreement would have to make sweeping changes to everything from industry and building, to land use, how cities run, and, of course, how we produce energy.
The report is comprehensive, citing over 6,000 scientific references, and its basic message is this: limiting warming to a rise of 1.5 degrees compared with pre-industrial levels will require an unprecedented amount of effort, but a rise of 2 degrees would be far more harmful and ultimately more costly, too.
Washington Post publishes possible last photo of missing Saudi journalist
Saudi Arabia has said the accusations are " baseless " and claims Khashoggi left the consulate shortly after he arrived. Erdogan's comments were his most direct suggestion yet about potential Saudi culpability in Khashoggi's disappearance.
Scientists with the Nobel Prize-winning IPCC said in order to have even a 50-50 chance of staying under the 1.5 degree cap, the world must become "carbon neutral" by 2050.
"Even at a little over 1.0°C warming, India is being battered by the worst climate extremes - it is clear that the situation at 1.5°C is going to worsen".
For example, a recent economic impact statement by the EPA and NTHSA regarding rolling back fuel economy increases noted the reality of mad-made global warming and concluded that it isn't economical to address.
Ten million people on small islands, low lying coastal areas, and river deltas would be protected by shaving 10 centimetres off the rise in sea levels.
The Arctic Ocean would be one of the most dramatically affected, with the region likely to experience ice-free summers every decade, compared with every century if we limit to 1.5.
The Livest Dog at UFC 229: Jussier Formiga
He bounced back from that defeat in style, mauling Edson Barboza for 22 minutes before the doctor's called the fight due to a cut. With that TKO win in his back pocket, Lee now looks for his next victim, and he sees some names on the horizon.
While an extra half a degree over that limit of 1.5 degrees might seem insignificant‚ a shocking landmark report just released by the United Nations has taken the world by storm‚ showing how hitting a 2 degree rise would spell doom.
An agreement was adopted by 195 nations in December 2017 at the 21st conference of the Paris to the UN Convention on Climate Change.
The IPPC report represents "sobering assessment of the challenge we face, and of the risks and costs of a warming planet", Caroline Theriault, a spokeswoman for Environment Minister Catherine McKenna, said. "The next few years will be critical in the evolution of these efforts".
However, all methods "are at different stages of development and some are more conceptual than others, as they have not been tested at scale", the report warned.
Coal power would also need to be reduced to nearly nothing. Despite the report's dire warnings, there is no indication such cooperation will be doable, particularly given the Trump administration's stance on this issue.
Scottish Greens' co-convener Patrick Harvie said: "We've always challenged the government to go further in its response to unsafe climate change".
