According to a study, the surface temperatures of the oceans rise faster: from 1985 to 1989 the increase was still 0.06 degrees Celsius per decade, so it was already 0.27 degrees from 2019 to 2023 – more than four times as much.
Until now, a straight line of this warming has often been adopted. The group around Christopher Merchant from the English University of Reading, published in the specialist magazine “Environmental Research Letters”, indicates that the temperature rise is speeding up.
From April 2023 to July 2024, the temperatures of the sea surfaces were high in the global average than ever. This also had to do with the intensive performance of the climate phenomenon El Niño. In El Niño, due to changes in currents in the atmosphere and the oceans, the sea surface temperatures in some parts of the Pacific are considerably higher than normal.
In the marine areas between the 60th degree northern width and the 60th degree of southern width, the surface temperatures up to 0.31 degrees Celsius were higher than the maximum values that were previously measured in the respective seasons. On average it was 0.18 degrees.
For these sea areas – they extend to the peak of St. Petersburg in the northern hemisphere, in the southern hemisphere south of Tierra del Fuego – the researchers investigated with the help of satellite measurement data and various climate models, which are the share of heating in natural phenomena – Such as El Niño or an elevated sun activity – goes back and which share is due to global warming made on the earth.
Male -Made Climate Change
Between the two strong El Niño events of 2015/2016 and 2023/2024, the peak values of the temperature of the middle sea rose by 0.22 degrees. According to the researchers, almost half (44 percent) go back to the human being made by humans – mainly due to the greenhouse gases that have enriched themselves in the atmosphere.
“Our results provide observation certificate that the global increase in the temperature of the Midden -Zee surface temperature in the past 40 years will probably be exceeded within the next 20 years,” the authors of the study write. When accepting a linear temperature rise, the predictions for the coming years would be considerably too low, they emphasize.
Accordingly, the trend of the temperature of the Middle Sea surface temperature, in essence, follows the tendency of the amount of energy that has gathered on earth in the course of the greenhouse effect -due to carbon dioxide (CO2) and other greenhouse gases in the atmosphere.
Carbon emissions must be urgently reduced
In a message from his university, the trader compares the increase in the temperatures of the sea surface with the filling of a bathtub: 40 years ago the rooster with the hot water was only slightly open, now it is considerably more. “The way to delay this warming is by closing the hot rooster by reducing global carbon emissions and going to the net zero,” the trader emphasizes.
