    with urgent, decisive action, we still can avoid unmanageable outcomes

    But not just any urgent, decisive action, it must be the right action. The wrong action could be insufficient at best, and actively harmful at worst.

    To meet the Paris climate agreement, we must reduce global GHG emissions by 45% to 50%, from current levels, by 2030. To achieve that, we must begin decommissioning all existing fossil fuel powered machinery, from power plants, to manufacturing, transportation, and agricultural equipment, and replace them with net zero emission alternatives, as quickly as possible. I don’t think anyone really knows how best to do that, at least not on a global scale. It’s not something we’ve ever done before.

      By 2030? Not going to happen, then.

      That means we need to come up with a different “right” action in the meantime. We shouldn’t be relying on a dream scenario that has basically no chance of actually coming to pass.

        You’re right, that would be virtually impossible. I should have said that we need to decommission the fossil fuel powered machines as quickly as possible, to have the best chance of reducing global GHG emissions by >45% by 2030. But, we do need to have all fossil fuel powered machines that have GHG emissions that can’t be offset by things like carbon capture and sequestration, decommissioned by 2050, to meet the Paris climate agreement goals. That gives us a couple more decades, but even that will be extraordinarily difficult.
