> But that's not something we can really control, any action we take on climate even the most drastic won't have any real effect for about 30-70 years at least. That is the wrong way to think about it. Any action we take now is affecting all future years. Replacing fossil fuels with renewables not only reduces carbon emissions this year but also over all the next years. Additionally, taking action now tips the economies of scales further. Renewables come cheaper, fossil investment unattractive. Thus I think the best way to face the looming catastrophy is to act more decisively and invest much more heavily now.
