Clouds study finds that low climate sensitivity is ‘extremely unlikely’
It is “very likely” that the way clouds change as the world warms will drive further temperature rise, a new study finds.
The response of clouds to a change in global temperature – known as the “cloud feedback” – plays a crucial role in how much the planet will warm. However, estimates of cloud feedback are uncertain. The new study, published in Proceedings of the National Academy of Sciences, uses global satellite observations to reduce this uncertainty.
Taking their findings into account, the authors produce a central estimate of equilibrium climate sensitivity (ECS) – the global temperature change resulting from a doubling of atmospheric CO2 – of 3.2C. They add that low ECS values below 2C are “extremely unlikely”.
Cooling effect of clouds ‘underestimated’ by climate models, says new study
Clouds could have a greater cooling effect on the planet than climate models currently suggest, according to new research.
The paper, published in Nature Climate Change, aims to correct a “long-standing” and “unaddressed” problem in climate modelling – namely, that existing models simulate too much rainfall from clouds and, therefore, underestimate their lifespan and cooling effect.
The authors have updated an existing climate model with a more realistic simulation of rainfall from “warm” clouds – those that contain water only, rather than a combination of water and ice. They find that this update makes the “cloud lifetime feedback” – a process in which warmer temperatures increase the lifespan of clouds – almost three times bigger.
I m not sure it just applies to covid response, too.

That was the point I was making, Covid will be controlled to a more or lesser degree as time passes, and life goes on, and the same pressing issues remain….still undealt and even exacerbated by both Labour and National.,,because they both have fundamentally the same political/economic ideology
You know I took the dogs for a walk yesterday, on the short walk though some trees to the dog park.three cars were parked under various trees with our fellow citizens living in them..one car a small hatch had what appeared to be a woman with a child set up with a tiny tent, forced to live like dogs all for the sake of this fucking obscene housing market …it is a sight like this was unimaginable only fifteen years ago. How anyone can witness sights like these and not Critique the government (whom ever is in power) is what I don t understand. I just assumed it was our civic duty to at any
