WASHINGTON: Extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans in recent years, which may explain the so-called 'pause' in global warming observed during the past decade, according to a new NASA study. Researchers from NASA's Jet Propulsion Laboratory (JPL), California, found a specific layer of the Indian and Pacific oceans between 100 and 300 metres below the surface has been accumulating more heat than previously recognised. During the 20th century, as greenhouse gas concentrations increased and trapped more heat energy on Earth, global surface temperatures also increased. However, in the 21st...
