(From Tech Times / By Allan Adamson)– The research, which was published in the journal Science Advances on Friday, March 10, and used data from thousands of robotic floats that measured water salinity and temperature, showed that the rate of ocean warming has nearly doubled since 1994 when compared with that which occurred in earlier decades.
Study researcher Tim Boyer, from NOAA’s Ocean Climate Laboratory, and colleagues found that between 1960 and 2015, ocean warming worldwide was 13 percent greater than estimates made by the Intergovernmental Panel on Climate Change or IPCC. The study likewise revealed that the warming started to spread deeper into the ocean.
“OHC [ocean heat content] has increased fairly steadily and, since 1990, has increasingly involved deeper layers of the ocean,” the researchers wrote. “All ocean basins examined have experienced significant warming since 1998, with the greatest warming in the southern oceans, the tropical/subtropical Pacific Ocean, and the tropical/subtropical Atlantic Ocean.”
The findings of the new study provide a grimmer outlook for consequences associated with warmer ocean water. The IPCC previously estimated that ocean warming can be blamed for 30 percent to 40 percent of sea level rise but based on the results of the new research, the figure would be more like 50 percent.
Increased water temperatures can cause frozen bodies such as glaciers to melt resulting in increased volumes of water in the oceans. The rise in sea levels, however, brings with it unwanted risks such as flooding and potentials for storm surges. People who live in coastal areas are particularly at risk.
