The issue stems from the rate of change that we are experiencing.
Prior climatic changes in Earths history tended to occur over longer time scales, thus allowing for flora and fauna to adapt to the changing conditions or thrive in specific geographical areas.
That isn't occurring this time around, we are able to count the rate of change on decade-long time scales rather than millenia-long time scales.
For example the last time we had global warming of 5-7'C, that took about 5,000 years.
The current rate of change is occurring 10-20x faster than what has occurred historically.

We are currently at 400~ ppm of CO2.
At about 1,000-1,500 ppm of CO2 we start to feel drowsiness. - We should hit that in the next 100~ years. (Frequently experience this level of CO2 as it's a normal environment when dealing with structural firefighting and confined spaces, some individuals will feel the effects sooner, especially with compromised breathing already.)
At 2,000 ppm we start to get headaches, sleepiness, poor concentration, increased heartrate, nausia and more.
It is also resulting in a mass extinction on an unprecedented level.

^ this is the stuff that scares me.
You can "adapt" to riseing sea levels, by moveing up mountains or higher elevated area's.
You can "deal" with micro plastics, makeing sea food something ineddible.
You cannot live without air to breath.
The fact that we could actually polute so much that we might suffocate ourselves with it.... thats scary to me.

To be fair, we are a very long way from suffocation.
In saying that, you don't want to cross the 2,000ppm barrier... And at 5,000ppm because we would be exposed to those levels for long duration's... Would be extremely dangerous.
I.E. I am allowed to be exposed to 5,000ppm for roughly 8 hours at a time, but I am going to exhibit various physiological and psychological issues... This is enough CO2 to start affecting your bone density and create kidney calcification.
CO2 is dangerous... And not harmless like the Anti-Climate change movement would like you to believe, but there isn't an immediate threat to our health for a long time, it's our grandchildren that would be suffering for our inaction though.
