If Climate Change Is Killing Us, Why Is Life Expectancy Increasing?

[The Lawspeaker]

If climate change effects aren't enough to put a noticeable dent in life expectancy, then why is climate change talked about as an apocalypse?

[Borealis]

Why do people have such a hard time understanding that not everything happens in a linear fashion? Just because the impacts so far have been minimal so far(to humans, other species are feeling it strongly), it doesn't mean that there isn't a point when shit will hit the fan.
