Discussing global warming, the public is interested in before total average air temperature near the Earth’s surface, but this only one of the cakes of the climatic Napoleon. Maybe you don’t noticed, but the oceans are so huge that it holds much more thermal energy than the atmosphere. 90% energy added to the climate system by humans is absorbed planetary water. Unfortunately keep track of this process difficult. On land, the temperature is measured by many weather stations, and on open spaces they are clearly not enough. In the early 2000s it began deployment of an autonomous flotilla of Argo instruments, which dramatically increased the amount of data but happening in deep water to this day remains a mystery.

Estimation of heat content at different depths over time (image of the authors of the work). In 2010, researchers discovered an imbalance in the global distribution of heat. If measured the energy that has been captured recently by greenhouse gases, it turns out that the atmosphere and surface of the ocean did not warm as much as it should. And this deficit has accumulated since 2004 of the year. Some believe that this is a result within the margin of error, and others suggest that “missing energy” should be sought in marine the depths. In addition, the rapid warming of the atmosphere in the 1990s, driven by the strong El Niño slowed down in the 2000s due to La Niña and many felt that global warming is over, and scientists can to go home. Research sheds new light on the problem, performed by Magdalena Balmaceda and Erland Kellen from European Mid-Range Forecast Center, and also by Kevin Trenbert of the National Center for Research atmosphere (USA). They collected and reanalyzed the results. water temperature measurements from 1958 to 2009. It turned out that the decrease in the amount of heat contained in the oceans coincides with strong volcanic eruptions that are released into the atmosphere light blocking particles. In addition, there has been a decline after 1998 of the year, which was remembered by the incredibly strong El Nino, because of which world temperature set a new record. If you don’t go in cycles in the atmosphere, all this is easily explained. El Nino implies an increase in the surface temperature of the eastern Pacific, and part of this energy is transferred to the atmosphere, which is why it heats up. But evaporation also means cooling the ocean. At the end of this period, the amount of heat in the ocean continued increase rapidly, especially at great depths. Researchers emphasize that warming of waters below 700 m has no analogues. About 30% of the warming of the oceans after 1998 falls precisely on this depth. Why exactly does this part of the oceans accumulate Is heat energy especially fast? This seems to be due to changes in its circulation. One study found that La Ninyi and the Pacific Decade could cause temporary lull of surface warming while the depths began energy. And when circumstances change again, this heat heats the surface of the ocean. Research results published in the journal Geophysical Research Letters. Prepared by Ars Technica.
