Edit: Downvoters please reply. For clarification, I am just arguing against the claim that climate change will "kill us all" in the literal sense.

Cold weather still kills way more people than hot weather. Warming has decreased the overall temperature-related deaths. 650,000 fewer people die per year than in the 80s and 90s. 18 million die per year from cold weather, 2.2 million from hot weather.

Interestingly, during the 2000-2019 period examined in the study, while heat-related deaths rose, deaths from cold exposure fell. And they decreased by a larger amount than the increase in heat-related fatalities. Overall, researchers estimated that approximately 650,000 fewer people worldwide died from temperature exposure during the 2000-2019 period than in the 1980s and 1990s.

World population has grown (4x) but natural disaster deaths have decreased to a fraction (less than 1/10th or less than 5,000 per year). This is because we are better prepared. A 40+x increase is required to reach 1920 levels per capita. And that 50,000 per year would still not be able to beat the 650,000 fewer people dying from temperature per year.

There will be no real socialism for several reasons.
