3. Is it realistic to think our climate is in a fragile state? What does burning fossil fuels have to do with global warming ice caps?

If not for our CO2, earth would be a block of ice and there would be no life here except near heat vents at the bottom of the ocean.

Because it's a stupid Hollywood movie and they needed sensational emotional scenes with animals going bonkers.
