Nature, land use and the role of the oceans as victims but also as solutions to global warming focus today the focus of attention of the United Nations Climate Change Summit (COP28). During the day, the publication of various reports on the situation of seas and oceans.
The oceans regulate the climate and are the best allies in the fight against global warming, as Rafael González-Quirós, director of the Gijón-CSIC Oceanographic Center, recalls in laSexta: “The ocean has absorbed 90% of the excess heat that we have caused as a consequence of the greenhouse gas emissions“.
The seas and oceans are the best elements for neutralize CO2: They can absorb 50% of the emissions, so their care is vital. They emit oxygen and absorb carbon dioxide, they are a source of wealth for tourism, they provide food and we use them for transportation. “More than 90% of merchandise transport is done across the oceans and accounts for only 4% of CO2 emissions,” recalls González-Quirós.
But they are also the major victims of the climate crisis. As its temperature increases, the waters become more acidic, the coral reefs disappear, mollusks can barely make their shells. All species suffer. Ethel Eljarrat, director of IDEAE-CSIC Barcelona, explains that “there are studies that show that each degree increase in sea temperature causes a 30% decrease in the weight of fish.”
An example is the Mediterranean Sea, which last summer exceeded 30 degrees in temperature. In 2050 it will be, in the best scenario, 2.2 degrees warmer than before the Industrial Revolution. And what happens in the sea is reflected inland, as Carlos Bravo, spokesperson for Ocean Care, warns: “This year we have already suffered droughts here in Spain, fires serious in Greece and Türkiye, floods in Libya”.
Experts demand an accelerated abandonment of the burning of fossil fuels. “The oceans They are the basis of life and we have to protect them not only if we want to continue obtaining food from them but so that the climate system as stable as possible,” says Bravo.
