Many scientists believe that the main cause of global sea-level rise is global warming, and the melting of glaciers and ice sheets has intensified. Recently, some researchers have found through statistical data that the snowfall in Antarctica has increased significantly in the past century, which has increased Antarctica. According to the amount of frozen water "stored" in frozen areas, some experts are optimistic that the trend of global sea-level rise will be reversed. Which of the following, if true, would most weaken the expert's point of view. ['According to relevant statistics, the amount of snowfall in Antarctica has decreased slightly in recent years.', 'The ice increase caused by snowfall is only one-third of the ice loss caused by melting glaciers.', "Researchers' analysis of causes affecting global warming may have missed some.", 'According to relevant meteorological departments, the global average temperature this year will be slightly lower than last year.']
