You’re right, but I want to note that climate collapse is a little more serious than an ice age. For one thing, the ocean is turning into acid. That’s because CO2 reacts with seawater to make carbonic acid. The pH of the ocean is balanced by calcium carbonate which can neutralise acids, but once the carbonate runs out, the pH will change WAY faster. Also, calcium carbonate is needed by crustaceans to make their shells. No carbonate means no crustaceans, which means no krill, which means the entire ocean food chain will collapse.
Humanity survived ice ages, it’s plausible any climate catastrophe will just be a bottlenecking event.
