It’s worse than we thought!!
Now where have we heard that before?
Many of the impacts of global warming are now simply "irreversible" according to the UN’s latest assessment.
But the authors of a new report say that there is still a brief window of time to avoid the very worst.
The Intergovernmental Panel on Climate Change says that humans and nature are being pushed beyond their abilities to adapt.
Over 40% of the world’s population are "highly vulnerable" to climate, the sombre study finds.
But there’s hope that if the rise in temperatures is kept below 1.5C, it would reduce projected losses.
Just four months on from COP26, where world leaders committed themselves to rapid action on climate change, this new UN study shows the scale of their task.
"Our report clearly indicates that places where people live and work may cease to exist, that ecosystems and species that we’ve all grown up with and that are central to our cultures and inform our languages may disappear," said Prof Debra Roberts, co-chair of the IPCC.
"So this is really a key moment. Our report points out very clearly, this is the decade of action, if we are going to turn things around."
This report from the IPCC is the second of three reviews from the world’s foremost body of climate researchers.
Last August, the first instalment highlighted the scale of the effect that humans were having on the climate system.
This new report looks at the causes, impacts and solutions to climate change. It gives the clearest indication to date of how a warmer world is affecting all the living things on Earth.

Of course, the first instalment last year also made similarly apocalyptic claims, even though the detailed report found little evidence that our climate was actually getting more extreme. Floods, droughts, hurricanes, wildfires, extreme temperatures – the IPCC failed to identify any significant trends at all.
It is curious then that this Part II should claim that the world is on a cliff edge. According to the Met Office:
Climate change risks worse than previous assessments while the world continues to warm.
A new report published today [Monday 28 February, 2022] by the IPCC paints the bleakest assessment yet for the impacts of climate change risks on society, human health, agriculture, ecosystems and wildlife.
One claim in this report is that ecosystems are being adversely affected through climate change:
Whilst subtle changes have occurred, such as the advance of species polewards, there is no evidence that these are in any way detrimental. Indeed, these shifts back and forth have regularly happened in the past.
They even lie that wildfire area has increased, when the reverse is true.
As we will see throughout this report, the IPCC rely heavily on studies written by grant funded activist scientists. Many of these are poor and easily debunked, and they usually are based on very dodgy computer models.
As very few scientists get funding for work that goes against the grain, it never gets included in IPCC reports.
Then they move onto the extreme weather lie, even though their first report could find no evidence that it was getting worse:
Climate change is also supposed to be stressing food systems:
The claim is that global warming has slowed the growth of agricultural productivity over the last 50 years. It is a claim we have come across frequently, always based on those GIGO computer models.
These so-called scientists claim to know what agricultural productivity would have been without global warming, and we expected to believe them!
But what we do know, because governments around the world were extremely worried at the time, is that the global cooling of between the 1940s and 70s really did have a detrimental effect on food output.
They then give us this strange segment on water scarcity:
I am quite sure a lot of the world is short of water. I have equally no doubt that this has always been the case. And it goes without saying that droughts make it worse.
But where is the evidence that global warming has made any of this worse?
Apparently we are also expected to believe that climate change has harmed human health, when all the parameters show that mankind is heathier than it has ever been.
The fact that this ridiculous report has to mention “women, children and indigenous people” proves that this is not a serious analysis, but one with a political agenda:
Climate refugees!
Quite what “weather-related migration” has to do with global warming eludes me!
And again the report confuses “weather” with “climate” when it examines economic effects.

But it fails to mention that economic losses as a proportion of GDP have been decreasing in recent years:
Many of the claims included in this AR6 report have been analysed in detail in the past on this blog and others. Most have been found to be shoddy, one sided, subjective, cherry picked and based around computer modelling.
The purpose of those studies was never intended to advance scientific knowledge, but to build up the “evidence” to be included in highly politicised reports such as AR6.
The Met Office are bragging that they have been heavily involved in the report, with Richard Betts as a Lead Author.
Far from enhancing their reputation, this merely shows how far their standards have fallen.
