Scientists at the University of California at Berkeley (USA) has concluded that anthropogenic greenhouse gas emissions contributes to a more rapid heating of the oceans than previously thought. This refutes the view that global warming in the past 30 years has slowed. Article researchers published in the journal Science.
Approximately 93 percent of solar energy that is captured by carbon dioxide and other gases, accumulates in the oceans. This figure is only weakly dependent on annual variations such as El Nino (temperature fluctuations of surface waters in the Pacific ocean) or large volcanic eruptions.
The researchers analyzed data about sea water temperature in the upper two thousand meters, acidity and salinity collected since the middle of 2000-x years, using four thousand of automatic buoys of the Argo project, and can occasionally sink to a certain depth. This allowed us to Refine existing models of climate change.
According to calculations of scientists, if not taken any measures to reduce greenhouse gas emissions, by the end of the century the temperature of the water in the upper layer with a thickness of two thousand feet will increase by 0.78 degrees Celsius. It will raise the sea level due to thermal expansion for an additional 30 centimeters in addition to the rise of the coastline due to the melting of glaciers. Rising temperatures will trigger more intense storms, hurricanes and extreme rainfall events.
In 2013, the intergovernmental panel on climate change (IPCC) presented a report, according to which the actual increase of heat in the oceans over the past 30 years is slower than predicted by existing climate models. This conclusion was based on data obtained by one-time bathythermograph, able only once to sink to the bottom of the ocean. However, the new information provided by the Argo system, is consistent with predictions of the rapid warming of the sea waters.
