The sheer speed of this climate change is one majorly significant factor.Just reiterating this point in particular, as it's pretty important.
The other is the fact that, no matter how often there have been climate changes in the past, there are now billions of people living on the planet, a fact that does not apply to previous changes. Millions are already affected, and billions will be in the coming decades and centuries.
We are officially in the Anthropocene era: the age in which our hominid species is actively changing the planet in ways that no species of animal ever has before.
