The world’s oceans are heating up faster and faster and becoming stronger. According to a report by the Chinese Academy of Sciences, in the journal “Science”.

The latest findings disprove, therefore, previous reports that the warming in the past few years, have exposed. “The warming of the oceans is a very important indicator of climate change, and we have solid evidence that it is warming faster than we thought,” said co-author Zeke house father of the University of California.

According to the investigation, the temperature of the oceans have increased in a depth of up to 2000 meters between 1971-2010 by 0.1 degrees Celsius. The 2013 published assessment report of the intergovernmental panel on climate change IPCC was assumed to be of lower values, even if the Figures are not directly comparable.

oceans take up the majority of the additional heat

About 93 percent of the mainly through the burning of fossil fuels in addition to heat generated will be so far absorbed by the oceans. In the past 150 years, the world’s oceans would be the equivalent of about a thousand times the amount of the annual world energy consumption of heat is absorbed, so the result of the beginning of January, in the journal “PNAS” calculation.

The strong heating of the oceans, let the sea level continue to rise, so the researchers in the “Science”post. The reason for this is the heat due to the greater thermal expansion of the sea water. This effect alone would lead to a swelling of the sea level of up to 30 centimeters. In addition, the warming of sea water leads to a further destruction of the coral reefs and reduces the oxygen content in the oceans.


Low oxygen levels threaten marine animals

The oxygen content in the world’s oceans has decreased since 1960, an average of more than two percent, found a study at the Geomar Helmholtz centre for ocean research in the year 2017. This Trend has far-reaching consequences for fish or other organisms in the already oxygen-poor marine regions, for example, because in particular large fish in oxygen are not able to survive poor areas. By 2100, the oxygen content could be reduced by up to seven per cent, in “Nature” published the survey.

more Precise Figures by the sea monitoring system

The new report in “Science” is based on four studies that were published between 2014 and 2017. An important factor for the more accurate Numbers a Maritime surveillance fleet with the name of Argo, which includes almost 4000 floating robot. This drive, according to the study of the oceans and diving every couple of days to a depth of 2000 meters, to measure data such as temperature and pH-value.

The new analysis shows that the warming of the oceans corresponds to the measurement data of the rising air temperatures. The emissions should not be reduced to greenhouse gas emissions, temperatures could increase up to a sea depth of 2000 meters by the end of the century, by 0.78 degrees Celsius, said the study. The climate researchers at Zeke’s house, father says: “While 2018 will be the fourth-warmest year since measurements on the surface of the earth, it is certainly the warmest in the oceans – as early as 2017 and 2016.”
