You have probably heard of staying under the 2C goal.

At 2C the warming feedback loop is self sustaining and will grow to 8 or 10C. At 2C, the permafrost melts, a LOT of methane is released. The oceans turn acidic and with a higher temperature can no longer support the algae that supplies most of the oxygen on the planet. By that point most of the planet will already be a desert because the majority of plant life and animal life cannot survive routine 130 or 140 degree temperatures.

Good luck surviving without plants, animals, or oxygen.

It's wild to me that so many people still deny climate change is real, even in the face of overwhelming evidence. Good luck with pretending your way to a better tomorrow!

Yes, humans have understood the consequences for decades, yet the problem grows larger every year.

Do you understand how that makes it worse?

The current trajectory is human extinction during your childrens lifetime.
