The new IPCC report is out, and unsurprisingly jacks up the alarm, as the absurd Matt McGrath reports:
Humanity’s damaging impact on the climate is a "statement of fact", say UN scientists in a landmark study.
The report says that ongoing emissions of warming gases could also see a key temperature limit broken in just over a decade.
The authors also show that a rise in sea levels approaching 2m by the end of this century "cannot be ruled out".
But there is new hope that deep cuts in emissions of greenhouse gases could stabilise rising temperatures.
This sober assessment from the Intergovernmental Panel on Climate Change (IPCC) features in a 42-page document known as the Summary for Policymakers.
It leads a series of reports that will be published over coming months and is the first major review of the science of climate change since 2013. Its release comes less than three months before a key climate summit in Glasgow known as COP26.
"Today’s IPCC Working Group 1 Report is a code red for humanity," said UN Secretary-General, António Guterres.
"If we combine forces now, we can avert climate catastrophe. But, as today’s report makes clear, there is no time for delay and no room for excuses. I count on government leaders and all stakeholders to ensure COP26 is a success."
According to Prof Ed Hawkins, from the University of Reading, UK, and one of the report’s authors, the scientists cannot be any clearer on this point.
"It is a statement of fact, we cannot be any more certain; it is unequivocal and indisputable that humans are warming the planet."
Petteri Taalas, Secretary-General of the World Meteorological Organization, said: "By using sports terms, one could say the atmosphere has been exposed to doping, which means we have begun observing extremes more often than before."
The authors say that since 1970, global surface temperatures have risen faster than in any other 50-year period over the past 2,000 years.
This warming is "already affecting many weather and climate extremes in every region across the globe".
Whether it’s heatwaves like the ones recently experienced in Greece and western North America, or floods like those in Germany and China, "their attribution to human influence has strengthened" over the past decade.
As I commented last week, this is the Summary for Policymakers (SPM), the result of negotiations between governments. In other words it is a political statement, not a scientific document. The latter won’t be published until much later, probably long after COP26.
And as Guterres makes clear, the whole object of the SPM is to scare governments into signing up to the UN agenda at COP26.
Notably there is nothing in the BBC report, and therefore presumably in the SPM, to show that extreme weather has actually got any worse. Nor does it seem likely that the full scientific review either, given that the IPCC has failed to find any evidence in earlier reports. Indeed, the only mention is this:
Instead it is all about projections of doom and catastrophe, based on computer models written by grant addicted climate scientists. Every IPCC Assessment Report since the first in 1990 has threatened us with apocalypse, and none of their warnings of disaster have come true. But that has not stopped each report using ever stronger language.
Consequently we are treated to threats of a 2 meter sea level rise, an ice-free Arctic, an increasing occurrence of some extreme events "unprecedented in the historical record”, and wildfires.
