Man-made climate change is not going to cause a mass extinction event. This is not supported by any credible science and it's not endorsed by the IPCC either. Global warming is largely benign and gradual enough that most people probably will not feel a couple extra degrees in the annual average (temperature flux varies much larger from day-to-day and from summer to winter). At the very least, it will be adaptable. The idea that most plants and animal life cannot not adapt to the equivalent of what would be bringing Richmond, Virginia's climate to New York City over the next 100 years is laughable. In the tropics, temperatures have changed [and will continue to change] very little. In most mid-latitude countries, warming will be beneficial: longer growing seasons and fewer cold weather-related hazards, just to name a few. Even if you believe that global warming makes [or will make] extreme weather worse, (1) more people die from cold air exposure than from extreme heat, so an increase in heatwave frequency and/or intensity will not be consequential for several decades, especially with access to A/C; (2) any increase in fire risk can be more than offset with better forest management; and (3) the CMIP5 / CMIP6 models show only a small ~4% increase in hurricane intensity (maximum sustained wind speeds) by 2100 in a worst case scenario. We can also easily mitigate flooding with better codes and infrastructure. Droughts can also be mitigated with better water resource management. As for things like tornadoes, future projections (if you put much, if any stock in them) are uncertain. None of this looks alarming, at least to me. Some poorer countries may see negative effects from global warming in the long-term, but that goes with any sort of climate change you get. Global cooling also would have negative effects, if not more. There are pros and cons to everything. Risk always is present and you are not entitled to zero risk. We need do also be cautious with AI (regulations and safeguards are important, especially for deep fakes), but most of fear mongering that I am seeing about AI has parallels to climate doomerism.
