Earth survived way higher co2 levels and we don’t emit nearly enough sulfides. There is essentially zero chance of Venus event happening. I’m more inclined that climate change can cause catastrophic war than runaway to ultra high temperatures.

- imtringued 6y agoPast CO2 levels aren't relevant because over time things like solar irradiance change as well. The amount of CO2 needed to maintain a certain global temperature shrinks over long time frames (hundreds of millions of years) as the sun gets hotter and hotter until it finally dies.
- ivalm 6y agoExcept sun hasn’t become meaningful hotter in the past hundred mil years. Also, we would need lots of sulfer dioxides to get emited, which isn’t happening. Will earth suffer over the next billion years and lose atmosphere? Sure, but that’s not what’s happening now.
