Earth has been 2C hotter & 1C cooler than now (Proxies) & is still exiting the last IceAge (~11kyrs ago) Especially as now is ONLY 1° above 1850 coldest in 8,000 yrs, 2° below warmest. Sighting of Stevenson Screens & the number of has varied since used, direct measurement only since approx. 1850's; numbers used & position near airports motorway is argued about. CO ₂ & Temperature relationship is wrong way around, H ₂ 0 (1% to 4%) is the main GHG, CO ₂ (0.04%) is Secondary. How does CO² affect the JetStream Civilised Humans need Fossil Fuels that are the main COG's ™ (Coal, Oil & Gas) of society; Renewables also require these, even Nuclear Businesses, Academics, Activists are all getting advantages to themselves promoting a 'Climate-Crisis', to the detriment of the ordinary person. This is complicating genuine science. SolarPanels & WindTurbines are not a direct replacement for these COG's, are unreliable & intermittent when needed;
