The fact that Donald Trump casually tossed off the idea of kneecapping lifesaving government climate research is terrifying, especially considering a major climate-change study was published the very same day. According to a report released Monday in the peer-reviewed journal Proceedings of the National Academy of Sciences, new satellite data shows that the rate at which ice caps in Greenland and Antarctica are melting is increasing, and researchers now warn that the seas could rise by as much as two feet by 2100.
The researchers caution that this estimate might even wind up being low.
"If sea level begins changing more rapidly, for
The study says "global mean sea level" has risen by roughly 3 millimeters per year since 1993, which resulted in nearly three inches of sea-level rise over the past 25 years. But thanks to rapidly melting ice sheets, that rate almost certainly will not hold: After reviewing data from satellites studying ice sheets in Greenland and the Antarctic, the researchers noted the rate of sea-level rise over those past 25 years slowly increased by about .08
Importantly, other respected scientists have also predicted a similarly dramatic rise. The two-foot estimate is roughly in line with what the United Nations' Intergovernmental Panel on Climate Change has already warned will occur by 2100, and the global climate-science community seems to be becoming
In and of itself, a two-foot spike in ocean levels would not necessarily end life as we know it in the Magic City. University of Colorado scientist Steve Nerem, the study's lead author, told the Associated Press earlier this week that Miami and New Orleans would be hardest hit by any spike in ocean levels but could mitigate the damage through technology such as sea walls and flood pumps. Many Miami-area cities are hard at work on these very projects: Miami Beach is in the midst of installing citywide pumps to prevent or mitigate high-
But two major problems remain with those efforts. For one, any type of tropical storm or hurricane in those kinds of conditions would inundate the city to an almost biblical degree. Miami already saw in 2017 what happens when even tropical-storm-level rain pours onto a rising ocean. Miami Beach and downtown Miami roads last year became impassable during multiple storms that weren't even hurricanes. After two feet of sea rise, a major-hurricane storm surge would spell catastrophe.
Perhaps more important, this estimate could rapidly become the low bar for future ocean-rise predictions. Some studies, such as a controversial one by the famed climate scientist James Hansen,
The same appears to be true for Miami and Florida as a whole. Despite the fact that no U.S. state stands to lose more property to climate change in the coming years than the Sunshine State, there appears to be no major political movement in Florida to take the steps (such as suing carbon polluters and mandating solar energy usage) necessary to prevent the ice caps from melting further.
