The Guardian convened45 climate scientiststo consider whether global heating is already unstoppable. Theirconclusion is, not yet, but without strong steps starting soon, it will be.They reported that overall global heating so far fits closely withpredictions, but the models don't predict local extreme weather verywell, and some of that has been surprising.Since local heat waves and disasters cause a substantial part of thedamage, I surmise that damage is rising faster than predicted. Thatincludes food shortages.Conclusion: Dramatic climate action needed to curtail"crazy" extremeweather.
