British Medical Journal study: "To meet the planetary health diet recommendations, average meat consumption in Africa can slightly increase (2%), whereas in North America and Europe it needs to fall by 79% and 68%, respectively. ... "Sustainable land travel will involve substantially fewer journeys by car and more journeys taken by foot, bicycle, and public transport, ensuring that all transport is carbon neutral and powered by renewable energy."

Breitbart News: A report produced by Cambridge University academics has called for foods with so-called high carbon footprints, such as dairy and meat, to be made more expensive in order to save the planet. The Cambridge University-led study published by the British Medical Journal (BMJ) says that “education” alone on changing diets towards more plant-based habits and abandoning car ownership is not enough. The report, “Changing Behaviour for Net Zero 2050” instead suggests there be “rapid, radical changes” to pricing in order to make normal food consumption and travel prohibitively expensive. In forcing people to abandon their cars, the scientists suggest increasing prices of fossil fuels and charging private car owners for road use, including “congestion zone charging and increased parking costs”. “Restricting availability and attractiveness of car use — eg, car-free zones, limited parking, traffic calming measures, and low-speed limits” was also recommended.

East Antarctica, which covers two thirds of the South Pole, has cooled a whopping 2.8°C over the past 4 decades; West Antarctica approximately 1.6″C. ..only tiny Antarctic Peninsula saw statistically insignificant warming.

Excerpt: Climate sensitivity to future increases in CO2 concentration is calculated to be 0.50K, including the positive feedback effects of H2O, while climate sensitivities to CH4 and N2O are almost undetectable at 0.06K and 0.08K respectively. This result strongly suggests that increasing levels of CO2 will not lead to significant changes in earth temperature and that increases in CH4 and N2O will have very little discernable impact...This is an unfortunate situation since world governments are implementing ambitious and expensive plans to limit the increase of global temperatures by reduction of CO2 emissions to atmosphere, and to achieve a net zero carbon economy, in the belief that CO2 emissions are the main driver of global temperature increases...

An increase in average Relative Humidity of 1% will result in a temperature increase of 0.03Kelvin. By comparison, CO2 is a bit player.
