Seawater to a depth of up to 700 meters is warming at a pace of 0.02 degree every 10 years worldwide, according to an analysis by the Meteorological Agency.
In its first analysis into deep-water temperatures, the agency says that rises in seawater temperatures could lead to higher sea levels because heat expands, and to an accelerated pace of global warming because the warmer water may absorb less carbon dioxide.
The agency used temperature data up to 700 meters below sea level sampled at between roughly 70,000 and 2 million spots each year since the 1950s. The data were collected by observation ships from the agency and other countries, and commercial ships that sampled sea temperatures at research institutes' request. (Japan Times)
