One thing scientists are sure will happen as the world warms is that the seas will rise, putting millions of people at risk of land erosion, flooding and permanent displacement. But ask experts exactly how far oceans will advance, and their answer gets far more qualified. A study published May 20 in the Proceedings of the National Academy of Sciences found that previous estimates of how bad sea-level rise could get were too conservative—and that coastal communities must contemplate more severe, long-term impacts from humans' addiction to fossil fuels. Researchers asked leading experts on the Greenland and Antarctic ice sheets to provide their best updated estimates for the future of these frozen masses as temperatures spike. Aggregating these, the researchers concluded that the range of outcomes scientists now consider possible has shifted markedly toward more melting and, therefore, higher seas. For example, in a business-as-usual scenario, the median estimate from the United Nations' last major climate report should have been more than doubled. In fact, the researchers found that it is unlikely, but plausible, that the oceans could rise a staggering 6.5 feet by 2100 if emissions levels continue to be high. That would swamp roughly as much territory as is contained in all of Western Europe and make 187 million people homeless. Since the United Nations' last major climate assessment, the scientists watching the Earth's major ice sheets have witnessed massive ice losses and tried to better model the way the sheets fracture, how liquid water interacts with the solid stuff, and the instability of ice cliffs. They have also done more to assess how these ice sheets behaved in previous warming epochs. They have not been able to provide more precise estimates for how bad things could get except to say the outlook is worse than they thought previously. As with many effects of human-forced planetary warming, the precise nature of some consequences will be known only after they occur, when it is too late. It is this sort of uncertainty that opponents of addressing global warming have played up to argue against action. Yet although it is possible to contemplate less-bad consequences at one unlikely end of the probability spectrum, it is also possible to foresee absolutely devastating results on the other end. And, as scientists have continued to refine their understanding of Earth systems, the distribution of the scenarios that seem probable has tended to move in the wrong direction. President Trump and those in his administration ignore scientists’ increasingly dire warnings to the peril of their children, grandchildren and the rest of humanity.

答案：
解析：
在第一段中提到，专家们对于海平面上升的具体程度给出了模糊的答案。而在接下来的描述中，提到了一项新的研究，该研究认为先前的估计过于保守。由此可以推断，“qualified"在此处的意思是"保留的、有保留的”，表示专家的答案并不是绝对的，而是有所保留的。因此，选项B "reserved"最接近该词的意思。
