Let's assume, humanity can decide to care more about the survival of our species, our duty to our descendants, than getting rich now. How long would it reasonably take to get to net-zero carbon emissions? How much longer with the planet continue to heat? Looking ahead 30, 50, or 100 years, what will the climate be in this best realistic-case scenario?
