What's the evidence of Near Term Human Extinction?


 @Voidisyinyang Voidisyinyang  in fact there is no scientific evidence that climate change will cause human extinction but there will still be some damages that can still kill people.

 "The effects of extinctions will worsen in the coming decades, as losses of functional units, redundancy, and genetic and cultural variability change entire ecosystems (14, 23, 24). Humanity needs the life support of a relatively stable climate, flows of fresh water, agricultural pest and disease-vector control, pollination for crops, and so on, all provided by functional ecosystems (12, 28). Examples documenting the ongoing biological annihilation are proliferating, each of them underlining the magnitude of the problem and the urgency of taking action."

You can see "Arctic news" blogspot for further details. Essentially photosynthesis shuts down after 104 Fahrenheit. The center of the continents are 5 degrees F. warmer than global average and are the "bread baskets" to feed people at scale. Fresh water is rapidly being depleted. Nuclear power plants will soon be melting down en masse. The East Siberian Arctic Shelf is the world's largest ocean shelf with hundreds of gigatons of pressurized methane that has been triggered to release a methane bomb to soon double global warming. The Aerosol Masking Effect is twice as bad as previously thought so that any decrease in sulfur pollution from diesel and coal then heats up Earth even more. A 40% decrease in sulfur pollution heats up Earth another 1 degree. There's 240 Zetta Joules of heat in the ocean that soon will be released.
