| We don't know how strong this effect is, but we do know the effect is logarithmic (every additional unit of C02 causes less warming). You don't know this. You are convinced of it, and it is wrong. See https://www.skepticalscience.com/saturated-co2-effect.htm for a debunking of this particular claim. Fossil fuels, nuclear and hydro power are currently the only viable options to keep modern civilisation running. Hopefully we eventually find an alternative, but it's insane to risk mass suicide to avoid a manageable change in the climate, on the utopian hope that wind/solar will somehow leap forwards in efficiency. And you're out of date. Real world costs per megawatt delivered is now lower for solar than coal. There is a lot of work to do to replace existing infrastructure, and this is not appropriate for all environments, but solar is definitely a cost-effective part of our future. That is not "the end of life as we know it". OK, that phrase is exaggerated. But, for example, a mass extinction of coral and shellfish due to ocean acidification is going to fundamentally change our oceans by a whole lot with who knows what long term fallout. And while we can mitigate warming effects with aerosols, we don't have a way to mitigate CO2+H2O = H2CO3 (carbonic acid). |
