4 Dr. Curry's entire commentary on the aftermath of CLIMATEGATE is posted at the end of my testimony. 3. What global climate models can and can't do well: Global climate models create a coarse grained simulation of earth's climate system using computers. These models simulate atmosphere, ocean, land surface, sea ice, and glaciers. Models use complex mathematical equations that can only be approximately solved on computers. Some of the equations and climate models are based on laws of physics.. However, there are key processes in climate models that are approximated and not based on physical laws. Hence, there are a LOT of"tunable parameters" in these climate models, including solar direct effects and CLOUDS. Climate models can't tell us anything about climate sensitivity to CO21, but recent studies may be shedding more light on CO2 saturation dynamics — Two recently-published papers found that doubling CO2 in the atmosphere led to minimal temperature increases. The calculated figures can be considered to be in margin of error territory and on past observational evidence they pose no threat to the climate on Earth. They also destroy the shaky scientific foundation upon which Net Zero rests. Eight Taiwanese scientists led by Professor Peng-Sheng Wei found that the sensitivity of the climate to a rise in CO2 atmospheric levels from 100 to 400 parts per million(ppm)was "negligibly small" at 0.3°C. The paper is complex and examines heat transfers as a function of longitude, latitude and altitude "as well as diffuse radiation determined by absorption bands based on wavelength,temperature and the concentration or pressure of carbon dioxide vapour." The rest of the article above is posted at the end of this testimony. And there is still a factor of 3 uncertainty in these models, as per Dr. Curry. In addition, the effect of our solar system transiting through a highly magnetized interstellar cloud(which appears to be a factor in changes observed on ALL the planets, as per extensive David Wilcock references on Gaiam to scientific articles)is not included in these models - https://web.archive.org/web/20230604143301/https://science.nasa.gov/science- news/science-at-nasa/2009/23dec_voyager Global models are exceedingly complex .. and are amazing tools for trying to understand how global climate works, but are NOT fit for making future predictions, simulating regional climates or extreme weather or climate events. 8 https://www.youtube.com/watch?v=YHhV_RY ac https://mindandmatter.substack.coli p/udith-curry-climatology-climate https://www.nickiikomes.com post/Judith-curry-climatology-climate-change-computer-modelinggreen- energy-greenhouse-gasses-84-1
