“…, as climate change crisis today may cause extinction of the existing life on Earth gradually, …”

If the environment changes slowly enough, evolution will allow most of the existing species to adapt and eventually become something different. If it doesn’t happen slowly, then there will be a mass extinction. At the conclusion of the mass extinction, the remaining survivors will evolve to fill the vacant ecological niches, creating new species in the process. The end result may be different in the details, but the same overall as convergent evolution optimizes the fits to the environment. If the dinosaurs hadn’t become extinct, mammals would probably have not become dominant and humans probably wouldn’t have come to be. Why is there so much fear about extinctions?

But it’s harder to imagine the damage it caused…compared to the Deccan Traps, and perhaps the Shiva impact. I don’t think the science is quite all settled.

I mean, we already knew some of them where killed on the impact, some of the blow and heat of the impact, some by the giant tsunami that was created, some by the rain of fire of the different rocks falling back in the atmosphere, and some by the cold created by the clouds shading the world from the sun.

This is also a climate change alert for humans.
