ISLAMABAD: NASA scientists studied ocean temperature measurements, and have found that in recent years extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans.
The new study used ocean temperature measurements from a global array of 3,500 Argo floats and other ocean sensors, and the researchers say this shifting pattern of ocean heat accounts for the slowdown in the global surface temperature trend observed during the past decade, said the study published in the journal Science.
Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory (JPL), Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized.
They also found the movement of warm water has affected surface temperatures.
Willis said that Greenhouse gases continued to trap extra heat, but for about 10 years starting in the early 2000s, global average surface temperature stopped climbing, and even cooled a bit.
