The heat-trapping behaviour of CO_2 was first accurately measured in the 19th century, and all climate change models do actually predict convergence, not linear rise. It's just that the point of convergence is not one compatible with civilisation as we know it.
- tialaramex 7y agoExactly. If global warming said the typical outside temperature in Seattle doubles to almost 600K then it'd be fair to argue that's crazy people extrapolating - water isn't even liquid at that temperature, no model we have could make sense. But actually the model says it will go up say 2 or 3K. Much less like a wild extrapolation, and unfortunately still completely terrifying because that is already far too much.

- goatlover 7y agoHow does anyone know what temperature rise is or isn't compatible with civilization as we know it, within the range of predicted temperature rises? One of the problems is that civilization is dynamic. New technologies come along, people change their habits, etc.
- dane-pgp 7y agoThe effects of temperature rises on crop yields could lead to very negative outcomes, given expected population growth and the hard limit of humans' minimum caloric intake. https://www.scientificamerican.com/article/for-crop-harvests-every-degree-of-warming-counts/ https://www.scientificamerican.com/article/for-crop-harvests... Perhaps rich countries can mitigate the likely increase in food prices, but it could destabilise large regions of the globe.
