Billions of birds dead, insect apocalypse, amphibian populations decimated, etc... But yeah people are just being alarmist, it's the end of the world and I feel fine.
Taken in context, the numbers paint a very expensive picture economically (trillions and trillions of dollars), as well as a grave tale of unnecessary suffering for many tens of millions of people, if not more.
And money is an abstraction. You could eliminate trillions and trillions just by hacking the systems that keep track of who has how much.
What I'm trying to say is not that the consequences of climate change aren't grave, but that without mentioning specific numbers and their relationship to other numbers that describe reality, and researching and choosing those in good faith, you are saying nothing.
If you want actual numbers and the relevant context, perhaps you could read the IPCC report.
