Heat in the oceans set a new record in 2019, proving accelerated heating of the planet. Oceans absorb 90% of the heat generated by greenhouse gases from burning fossil fuels, destroying forests and other human activities, reports The Guardian.
Scientists from the University of St. Thomas in Minnesota, USA, found that 2019 was not only the warmest year in the history of observations, but also showed the largest increase in temperature in 10 years. This discovery is published in the journal Advances In Atmospheric Sciences.
Specialists used data collection methods in the most inaccessible places, for example, under the Arctic ice cap. Most of the information was obtained from 3.8 thousand sensors scattered across the oceans. The oceans warming rate from 1987 to 2019 was 4.5 times higher than from 1955 to 1986. Most regions of the oceans show a sharp rise in temperature.
Hotter oceans melt ice, causing sea levels to rise. The past 10 years have shown the highest water levels since 1900. Scientists predict that by the end of the century, the seas will rise by 1 m across the planet, affecting 150 million people.
Overheating of the oceans leads to more ferocious storms and disrupts the water cycle. This causes flooding, droughts and forest fires, as well as an abnormal increase in water levels on the coasts. High temperatures harm marine life, the number of heat waves in the oceans and on land increases sharply.
The last 5 years have become the warmest period recorded in the oceans. If every person on the planet turned on 100 microwave ovens for a whole day, a tremendous amount of energy would be released. About as much heat has already entered the oceans due to human activities.
