That's not entirely true. If we cut off carbon emissions right now, you'll still get the runaway train that is global warming, yes, but it will end sooner or will have a lesser peak temperature increase.

This is what the oil companies want you to think. The less hope you have the longer they'll keep making profit. They still receive trillions in public subsidies, it's criminal.

We may never go back, but if we did cut 100% of emissions tomorrow, it would have a huge impact. These penguins would have a much better chance for the future, for one, and so would plenty of other species.
