Wilson Cloud Chamber: Negative Feedback Against Agw by Clouds

Authors: Nige Cook

The lower the cosmic ray intensity, the greater the temperature: precisely what the Wilson cloud chamber mechanism predicts for cloud cover such as cirrus (around 15,000 feet). Cosmic rays boost Wilson cloud cover, increasing Earth’s albedo, cooling the planet. Calder’s “theory” of Wilson cloud chamber is not an opinion or a “speculative theory”, it’s a hard fact-based theory, going back to the earliest days of nuclear physics. The “error bounds” in the hockey stick curve are the fiddle. It’s true that global warming exists. What’s not true is the fiddles and fudges used to censor out the true extent of natural variations in order deliberately to correlate recent temperature rises simplistically to CO2 rises. Earth’s temperature fluctuates widely, but this has less effect on tree ring growth and ice sublimation than the IPCC believes, because as the air temperature goes up the cirrus cloud cover increases which partially cancels the increased growth of trees and the increased sublimation of ice (both of which depend on sunlight exposure to trees and ice, not just air temperature as the IPCC assume). Try saying this, and you are into classic taboo territory, in which it is socially nice to tell lies and pretend that CO2 is causing the temperature rise in the contrived hockey stick, which mashes together a horizontal line from tree ring proxies where naturally variable temperature swings are cancelled out by corresponding cloud cover variations, to more recent satellite data which shows a real temperature swing upward which isn’t seen in the tree ring proxy falsehood. There is a 50% chance of increasing or decreasing natural temperature swings, since a variable can increase or decrease with time (two possibilities). CO2 has an effect, but due to negative feedback (increased cloud cover to reflect sunlight away as the earth warms up), there is a thermostat in place which the IPCC exclude from the entire range of their climate models. The IPCC assumes (without evidence) that 100% of the temperature rise since satellite data arrived has been due to CO2 and related greenhouse gases. This is a pseudoscientific assumption.
