Current climate model simulations overestimate future sea-level rise

The current climate model simulations, which do not take ocean eddies into account, project that the ocean temperatures around Antarctica are increasing under climate change. The new high-resolution simulation shows…

$10 Million AI Grant to Improve Climate Modelling of Clouds

A Team of Scientists plans to use AI to improve climate modelling of sub-grid scale phenomena such as turbulence and clouds. But there is no reason to think an AI…

The Problem with Climate Models

So it may well be, no, it is likely that once the underlying physics is properly understood, climate models will emerge that produce an ECS value considerably smaller than 1.8C.…

There Are Models And There Are Models

Guest Post by Willis Eschenbach I’m 74, and I’ve been programming computers nearly as long as anyone alive.  When I was 15, I’d been reading about computers in pulp science…

Compensation between cloud feedback + ECS and aerosol-cloud forcing in CMIP6 models

The new open-access paper – the senior author of which, Gabriel Vecchi, is a well known professor of geosciences at Princeton University – provides further evidence that high ECS CMIP6…

Junk Grade Models: Even Short-Term Climate And Weather Modelers Get It All Wrong

Reposted from NoTricksZone By P Gosselin on 19. February 2021 Many climate policies are based on scenarios generated by models. Depending what these models churn out, actions and costly regulations get enacted to…

Here comes the new generation of climate models: the future of rainfall in the Alps

Next generation climate models are developed and applied by the CMCC Foundation in several international projects and contexts. Some examples include the study of urban heatwaves and the evolution of…

Climate Model Failure

By Andy May On January 22, 2021, John Christy presented a new online talk to the Irish Climate Science Forum. The talk was arranged by Jim O’Brien. A summary of…

Meet The Team Shaking Up Climate Models

They have gathered some of the brightest experts from around the world to start to build a new, modern climate model. They hope to corral the vast flow of data…

Canada is Warming at Only 1/2 the Rate of Climate Model Simulations

Canada has huge year-to-year variability in temperatures due to its strong continental climate. So, to examine how observed surface temperature trends compare to climate model simulations, you need many of…

Committed warming and the pattern effect

Zhou et al.’s estimate of committed warming (future warming with forcing remaining unchanged) follows fairly directly from their estimate of the pattern effect, if one accepts their bases and assumptions.…

UCI researchers: Climate change will alter the position of the Earth’s tropical rain belt

Future climate change will cause a regionally uneven shifting of the tropical rain belt – a narrow band of heavy precipitation near the equator – according to researchers at the…

The Rational Climate e-Book

By Andy May Patrice Poyet has just published a new 431-page eBook entitled, The Rational Climate e-Book, it is free to download here. Dr. Poyet studied geochemistry, remote sensing, and…

UW Researchers Find Wildfire Smoke is More Cooling on Climate Than Computer Models Assume

A study of biomass burning aerosols led by University of Wyoming researchers revealed that smoke from wildfires has more of a cooling effect on the atmosphere than computer models assume.

Inside The Bayesian Priory

Anyone who thinks that a description of reality is only worthwhile if it matches the output of absurdly simplistic climate models is not worth my time to investigate.

Study: Dangerous Global Warming Could Occur by 2027

We laughed when Alexandria Occasio Cortez claimed that the world would end in 12 years. According to a new climate study, AOC is an optimist; we might only have seven…

Of Warm Poles and Cold Tropics

Why are the poles warm and the tropics cold, and compared to what? An equivalent question is: what determines the difference in temperature between tropics and poles, and can we…

Study: “Venus was once more Earth-like, but climate change made it uninhabitable”

Despite the unsettling title, the authors are not trying to say Earth will end up like Venus if we don’t mend our wicked ways. But the Forbes article and study…

Study: Climate Change Increases the Risk of Global Pandemics

Any change is bad? according to a new study, warming in cold climates or cooling in warm climates increases the risk of animals getting sick, which in turn increases human…

Strengthening the climate change scenario framework

Over the past decade, the climate change research community developed a scenario framework that combines alternative futures of climate and society to facilitate integrated research and consistent assessment to inform…

Some Amazon rainforest regions more resistant to climate change than previously thought

New observational study demonstrates that increasing air dryness does not reduce photosynthesis in certain very wet regions of the Amazon rainforest, contradicting Earth system models that show the opposite

A sweeping climate model of the Red Sea

Projections of atmospheric and oceanic processes in the Red Sea are informing the design of sustainable megacities being planned and built along its shores.

CMIP6 adds more value in simulating extreme temperatures in China

Climate models have provided an avenue for studying the possible changes in extreme temperatures in the future; and in this respect, to ease of comparison across models from different modelling…

Disconnect in the relationship between GMST and ECS

Abstract. An analysis is presented of he disconnection between the CMIP5 and CMIP6 Historical and Future periods when considering the relationship of the individual model GMST changes and the climate…
