I'm optimistic. I'm sure a global warming of 5 to 10 degrees is unavoidable by now. Much of the comfort people currently have might disappear... but given the fact that people live and survive in Australia, I'm confident some degrees are survivable. It won't be a fun ride, tho.
- phtrivier 4y agoNo, 5 to 10 is not unavoidable, sorry. The current most likely scenario assuming status quo is between 2 and 4, if i recall my IPCC properly. And it's really _not_ the same as 10 !
- titzer 4y agoPolitically unavoidable, IMHO. That cheap fossil fuel energy is just too hard to pass up. It's like trying to convince several billion starving people to not eat the marshmallows right in front of them.
- blueflow 4y agoWe haven't stopped digging out carbon and inserting it into the carbon cycle. So there is no end to the warming in sight.
- rand49an 4y agoAnything between 5 and 10 degrees average rise will kill all life on earth.
- blueflow 4y ago85% of the prehistoric time earth was like that, its called greenhouse earth or acyrogenic climate. Dinosaurs lived when it was around 10 degrees hotter, and they did not die from that. Right now we are living in a icehouse earth where polar caps are a thing, which is not the case in a greenhouse climate.
