Climate change Research: Unusually high ocean temperatures have become more common, with researchers saying there is no return

Previously Rarely high temperatures have become the new norm in the world’s oceans, he says In the Plos Climate Journal study released on Tuesday.

According to the study, ocean temperatures appeared to have reached a “situation of no return” as early as 2014.

In the study, U.S. ecologists analyzed surface temperatures in the world’s oceans from 1870 to 2019. They found that extreme temperatures, which occurred only two percent of the time a century ago, occurred at least half of the time since 2014.

“Climate change is not something uncertain that could happen in the distant future – it is a historical fact and has already happened,” says a researcher in the research team. Kyle Van Houtan to the British The Guardian.

“Extreme climate change is here in the ocean, and the ocean is the foundation of all life on Earth,” says Van Houtan.

In the study monthly ocean surface temperatures were analyzed by block. The extreme temperature was defined as the highest temperature in the first 50 years of the time period analyzed.

By 2014, more than half of the monthly heat records exceeded this benchmark in the world’s oceans. In the study, the year when the percentage exceeds 50 and does not fall below it in subsequent years is called the “point of no return”.

The Southern Atlantic was the first to reach this point as early as 1998.

“It’s amazing that it was 24 years ago,” Van Houtan tells the Guardian.

By By 2019, 57 percent of the oceans were already suffering from extreme temperatures.

“We expect this to continue to grow.”

Professor of thermodynamics involved in evaluating the study John Abraham tells the Guardian that the oceans are a critical part of understanding climate change. They cover about 70 percent of the earth’s surface and absorb tremendous heat.

“This new study is useful because scientists are looking at surface temperatures. The study finds that extreme heat has increased significantly on the surface of the ocean and that extremes are increasing over time. ”
