When it comes to images related to climate models, the idea is closely based on any image classification algorithms that are used in ML. Scientists at NERSC have come up with a novel method to identify and establish patterns using a DL technique called Convolutional Neural Network (CNN).
Climate models have suggested that human-caused climate change could cause this cycle to slow, as warmer ocean temperatures and fresh water from melting ice stop water from sinking as it normally would, which would drive the cycle. If that slowdown really does happen, the climates of North America ...

Industry questions climate models in regulatory fight. Camille von Kaenel, E&E News reporter. Published: Wednesday, March 14, 2018. A trade group for automakers sent federal regulators research that calls into question climate modeling and the effects of global warming as part of its efforts to loosen fuel efficiency rules.
For these studies, concentrating on a small detail in a full climate model is like trying to find a needle in the haystack. It is therefore common practice in such cases to take away the haystack by using simpler climate models. Scientists usually write these models for specific projects. A quote commonly ...
Not all climate models have the same value. A paper led by Professor Francisco J. Tapiador at the University of Castilla-La Mancha argues that as climate models are increasingly used for societal applications, a focus on gauging their reputations in order to prune those not up to industrial-grade quality ...

"The group is currently plugging in historical data generated from a range of global climate models to see how well they can reproduce past hurricane seasons," states the release. "This understanding will allow them to adjust the model to simulate future hurricane seasons," according to the announcement.
Second, GCMs produce data at a very low resolution — so low, in fact, that some scientists have suggested that it may take upwards of 50 years for climate models (especially precipitation) to be able to meaningfully contribute to agricultural impact modeling. This is because while it's practical for some uses ...
Notably, when contemporary climate models – the same as those used in the United Nations' latest Intergovernmental Panel on Climate Change reports – were run under Eocene conditions, many could not reproduce these findings. Instead, the models steadily underestimated polar ocean warming in the ...
A new international analysis of marine fossils shows that warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse of Earth's potential future climate, was greater than previously thought.

No one knows why this is, although plenty of have offered explanations both scientific and magical. Climate scientists at the University of Bristol have gotten a little more serious about it and tried to simulate the weather patterns of Westeros by tweaking a real-world climate model. What did they find out?
One big problem confronts Africa as it tries to predict how its weather patterns will shift in the face of climate change: Almost all the climate models for the continent were created in the United States or Europe. Now South African climate researcher Francois Engelbrecht has changed that by developing a ...
Well, if you've ever wanted to debate fan theories, here's an excellent new resource for you to draw from: a real climate model simulation of Westeros and Essos. The study ...

The researchers plan to explore the effect different types of clouds have on climate-model projections, as well as how cloud cycles influence the ...
The study found that climate models factor too much of the sun's daily heat, which likely results in warmer and drier model projections than what might actually occur. The researchers analyzed satellite images from 1986-2005 to calculate average diurnal cycles of clouds in each season across the world.
