Hot seas? Oceans boil at the hottest temperature ever recorded


Global warming does not just cook our atmosphere, it also warms the oceans.

The seas of the world were the hottest ever recorded in 2018, scientists said this week. In addition, the temperature of the oceans is rising faster than expected, says a new document.

In particular, they are warming up to 40% faster than estimates of a UN panel five years ago.

"If you want to see where global warming is occurring, look in our oceans," said co-author Zeke Hausfather in a statement released on Thursday. "The warming of the oceans is a very important indicator of climate change, and we have strong evidence for warming faster than expected," said Hausfather, climate specialist at Carbon Brief.

He also stated that, while 2018 was the 4th hottest year ever recorded in the atmosphere, it was the hottest year ever recorded in the oceans, just like 2017 and 2016 before. In fact, Hausfather told Reuters that records of ocean warming have been broken almost every year since 2000.

Overall, although we are rightly concerned about the effects of climate change on our atmosphere, ocean heating is essential because it is estimated that 93% of the heat trapped by greenhouse gases is installed. in the oceans of the planet.

Global warming is caused by humanity burning fossil fuels such as oil, gas and coal, which release greenhouse gases such as carbon dioxide and methane into the atmosphere and oceans of the earth.

"Global warming is here and already has major consequences. There is no doubt, none! "Wrote the authors of the newspaper.

The new analysis also shows that trends in the heat content of the oceans are consistent with those predicted by the major climate change computer models.

Laure Zanna, an associate professor of climate physics at Oxford University who did not participate in the study, told The Grouvy Today that this new research was "a very good summary of what we know about the ocean and the scope of the new estimates. came together. "

Unusual heat in the seas is damaging to marine life and coral reefs. This also contributes to the rise in sea level worldwide as the ice melts near Antarctica and Greenland.

The research was published Thursday in an article in "Perspectives" of the journal Science.
