"In a statement the authors of the paper said: 'Since publication of our paper we have become aware of two mistakes which impact the detailed estimation of future sea level rise. This means that we can no longer draw firm conclusions regarding 21st century sea level rise from this study without further work. One mistake was a miscalculation; the other was not to allow fully for temperature change over the past 2,000 years. Because of these issues we have retracted the paper and will now invest in the further work needed to correct these mistakes.'"
Amusingly, the authors aren't disclosing whether they overestimated or underestimated the rise of seas. They'd said 0.75 to 1.9 meters by 2100. The IPCC had said 18 to 59 centimeters. So, let's stay terrified.
And I love the phrase "we can no longer draw firm conclusions." Somehow, they once had firm conclusions. But they were wrong.
