UN Climate Panel Contends With Models Showing Implausibly Fast Warming
Next week, the United Nations Intergovernmental Panel on Climate Change (IPCC) will unveil its latest scientific assessment, widely considered the most authoritative review of climate research. But ahead of its release, scientists have had to grapple with the fact that several next-generation models used in the assessment project that the Earth will warm far faster than previous estimates, Science reported.
“You end up with numbers for even the near-term that are insanely scary — and wrong,” Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, told Science.

Climate panel confronts implausibly hot models
report's authors face a challenge that many of the world's leading climate models, used for the report's projections, are now showing warming rates that most scientists believe are implausibly fast because of errors in rendering clouds. Scientists have scrambled to adapt to this new reality, constraining model projections with recent warming and adopting new techniques to convey the impacts of climate change.

Past models showed that a doubling of atmospheric carbon dioxide would lead to warming of 2 degrees C to 4.5 degrees C. Many new models, however, show that doubling CO2 would lead to warming of more than 5 degrees C,
exceeding all expectations
Is climate change happening faster than expected? A climate scientist explains.
One to 2 degrees Celsius of warming can do a lot of damage.
Climate scientists have long warned that global warming would lead to extreme heat in many parts of the world. But the 120 degree Fahrenheit temperatures brought on by the heatwave in the Pacific Northwest in June were more in line with what researchers had imagined would occur later this century.
This catastrophic summer even has climate scientists worried,” a headline in the National Observer read. “Climate scientists shocked by scale of floods in Germany,” the Guardian wrote. CNN: “Scientists are worried by how fast the climate crisis has amplified extreme weather.”

Knowledge of what is driving all these
wildfires and floods is not enough to enable us to do anything meaningful to stop it
Our leaders look climate change in the eyes, and shrug
The latest G20 meeting wrapped up last week without firm commitments on phasing out coal power, or on what steps nations will promise to take to try to hold global warming to 1.5C. This goal is both necessary and, perhaps, unlikely – a report by scientists found that China, Russia, Brazil and Australia are all pursuing policies that could lead to a cataclysmic five degrees of warming.
Viewing humanity and its pollution as a malicious virus set to be eradicated by nature is now a fairly compelling metaphor. Homo sapiens rose above the lesser animals thanks to our ability to wield logic and reason, yet we have somehow gotten ourselves to a place where
