The article itself did not focus on making predictions on global warming. The title, while a bit sensationalised, is not wholly inaccurate and was probably picked by the editor not the writer. The other two claims that I could find were about the potential damage of a six-foot sea level rise, which was probably accurate even if it didn't list out the likelihood of such a rise, and the article by the Union of Concerned Scientists which made a claim about the likelihood of increased flooding that seemed reasonable to me.
