New report in Science says oceans heat up 40% faster than we knew




(Newser)

The oceans heat up about 40% faster than previously measured, scientists say – which seems to confirm only the biggest headache in the world. Published in Science Recent reviews suggest that ocean temperatures are more in line with gloomy climate model simulations than scientists knew. The new measurements confirm that oceans could warm to 1.5 degrees Celsius and rise to nearly one foot of warming alone by 2100, adding melting ice caps, Scientific American . The studies are based on a network of swimmers that measures sea temperatures around the world. The so-called Argo network, which was developed in the early 2000s, is considered to be better than the old method of ships that drop sensors using copper wire into the ocean (New York Times ).

In a fourth study, sea temperatures were measured differently ̵

1; by measuring oxygen and carbon dioxide in the atmosphere – in an October article – but it also agrees with climate models. All in all, the report says that sea temperatures have broken records in recent years and have risen on average by 500% between 1991 and 2010, compared to between 1971 and 1990, according to ABC News Australia. As oceans solve problems by absorbing 93% of the heat trapped by greenhouse gases, it destroys marine life, worsens hurricanes and causes oceans to rise, scientists say. A typical example: A study from Florida estimates that by the year 2040, more than 67,000 septic tanks in Miami-Dade County are expected to fail as the sea level rises. "That's unacceptable," says a Miami water officer to the Miami Herald . (Meanwhile, a youthful environmental activist tells executives that they are too immature to act.)
