Climate skeptics are today walking tall. A new study by ten eminent climate scientists has revealed that IPCC estimates of humanity's remaining "carbon budget" have missed by a mile. What this means is not merely that "this carbon-budget approach" is "immature scientifically," as one expert noted, but that IPCC forecast models are so out of sync with real-world temperature data as to be virtually worthless. As a ground-breaking 2014 study concluded, estimates for climate sensitivity based on actual temperature readings "suggest that considerably less warming and sea level rise is to be expected in the future than the model projections imply." This all comes as unmitigatedly good news.
