You are traveling towards a concrete wall at 100 mph. It's all fine, we've been here before... moving at 1 mph.
Yes, Earth had been hotter and cooler, oceans had been higher and way lower... What is objectively novel is velocity of the current climate change. That is terrifying because we don't know if planetary feedback mechanisms can handle that. Looking at Venus, the worst case scenario is pretty bleak, but probably unlikely given further distance from the sun.
- Turing_Machine 4y agoVenus's atmosphere is 96.5% carbon dioxide, orders of magnitude more than the 0.04% found on Earth. Most of Earth's original CO2 is tied up in the kilometers of carbonate rocks that cover a substantial portion of the Earth's surface. That's not going anywhere.
- TrainedMonkey 4y agoI would love to know more about that, what resources would you recommend? Concur that mostly CO2 atmosphere is highly unlikely, what do you think about melting Siberian permafrost releasing localized methane and accelerating melting feedback loop?
