New Review in ‘Science’ Says Oceans Are Heating Up 40% Faster Than We Knew




(Newser)

The oceans are warming about 40% faster than previously measured, scientists say, which seems to confirm only the biggest headache in the world. Published Thursday at Science a review of recent studies states that ocean temperatures are more attuned to the terrible simulations of climate models than scientists knew. The new measurements confirm that the oceans could warm up by 1.5 degrees Celsius and rise nearly a foot within 2100 by heating alone, with loose ice caps adding more, Scientific American reports. The studies are based on a network of floats that measure ocean temperatures throughout the world; the so-called Argo network, developed in the early 2000s, is considered better than the old method of ships that drop the sensors in the ocean through copper wires, according to New York Times .

A fourth study measures ocean temperatures differently, observing oxygen and carbon dioxide in the atmosphere, for an October article but also agrees with climate models. All in all, the review says that ocean temperatures have recorded records in recent years and have increased by an average of 500% faster between 1

991 and 2010 compared to 1971 and 1990, according to ABC News Australia. While the oceans lighten the problems by absorbing 93% of the heat trapped by the greenhouse gases, this heat destroys marine life, hurricane worse and makes the oceans rise, say the scientists. Case in point: A Florida study estimates that more than 67,000 Miami-Dade county septic tanks will not function properly by 2040 with rising sea levels. "It's not acceptable", a Miami water officer tells Miami Herald . (Meanwhile, a teenage climate activist tells leaders that they are too immature to act.)
