An abandoned repository of over 3.1 million cubic feet (87,782 cubic meters) of radioactive debris left over from nuclear testing in the South Pacific is in danger of being cracked open by rising ocean levels, threatening to spill large amounts of the nuclear waste contained within—including highly-toxic plutonium—into the surrounding
The National Park Service (NPS) and the University of Colorado have released a joint report on sea level rise, despite alleged attempts by NPS officials to censure the report’s discussions regarding the effects of human activity on climate change. Its release follows a delay caused by a lengthy administrative review that started in early 2017, and the attempted editing also appears to be
A new study published in the journal Nature has illustrated that the global rise in sea levels is worse than originally anticipated, and the rate of increase is accelerating. Between 1993 and 2014, the rate of increase jumped by 50 percent, with the average rise in 1993 being 2.2 millimeters (0.87 inches), and 2014 showing a rise of 3.3 millimeters (0.13 inches). This study follows an earlier paper that found that sea level increases are now nearly triple that of their pre-1990 levels.
Global sea level rise has been assumed to have been rising at an average rate of 1.5 centimeters (0.6 inches) per decade since 1900, as measured by NOAA. However, a new study has cast that figure into doubt: after having taken regional sea level increases into account, the previously accepted rate may be off by a great deal — from 5 to 28 percent in some regions.
The problem comes from the fact that sea level measurements have been historically taken from coastal tide gauges, from roughly a dozen select sites around the northern hemisphere. It was assumed in the past that ocean levels were rising relatively evenly across the globe, however:
