Bruce Melton – We Can Have a Healthy Climate With Zero Warming in Our Lifetimes

We can have a healthy climate — a climate with zero warming — in our lifetimes. The message for the last 20 years has been that we have to reduce emissions drastically to prevent dangerous climate change of more than 2 degrees C (3.6 F). This strategy would have likely worked when it was first suggested, but we have delayed far too long since then. Now, even stringent emissions reductions allow our warming to at least double and likely triple before finally beginning to cool.

We must begin to reduce the load of already-emitted, long-lived carbon dioxide (CO2) climate pollution in the sky, regardless of costs. The good news is that, not only will costs be very similar to many things we do in our society today whose costs are taken for granted, but by disconnecting emissions reductions strategies from the removal of already-emitted climate pollution in our sky, we vastly simplify the myriad strategies that have been developed to avoid dangerous climate change.
