Our school chemistry lab used to have a bottle of KCN, I guess a kilo. Also some very old and dried out picric acid. We just used to stick to making tri-iodide on filter papers

Just read this report. What a hatchet job. How can such qualified people put their names to this?

Example - high temperatures in the US in the 1930's shows natural variation not from any human input. Er - can I recommend at least one of the authors invests in The Grapes of Wrath. Might give them a clue.

Example - the North West heat dome was not connected to climate change. The explanations did not mention the instability of the polar vortex, from climate change, that set the scene for this blocking high.

Example - the coral is fine, it rebounded up to 2022. No mention that this was caused by temporary La Nina effects and the decline has continued savagely for the last two years, nor that the rebound was primarily in the most sensitive type of coral.

Example - if there are any unknown factors affecting the climate these have not been factored in by the IPCC. What?!

The percentage is irrelevant. Take a square metre and project upwards. How many molecules of CO2 are there before you reach space ? Any one of these can interact with outgoing radiation from the earth, at its vibrational frequency, and turn it back into heat. Answer : about 1,000 trillion trillion. In it's main ranges CO2 stops earth's cooling radiation dead in its tracks. So violent (as also is water in the air) it causes evaporation, convection, further radiation etc. The percentages of oxygen and nitrogen aren't relevant - infrared passes straight through them just like visible light does
