The purple and blue colors are where there is the least ozone, and the yellows and reds are where there is more ozone. Better awareness and understanding of the oceans are a basis for the actions to combat climate change,” said Michael Mann, professor at the University of Pennsylvania and one of the authors of the study.įalse-color view of total ozone over the Antarctic pole.
“Until we reach net zero emissions, that heating will continue, and we’ll continue to break ocean heat content records, as we did this year. The scientists said that the global long-term warming trend is now so steady and robust that annual records continue to be set every year. Since 1970, more than 90% of the planet’s excess heat went into the oceans, the study said. Covering almost three quarters of Earth’s surface, oceans absorb the vast majority of the world’s heat. Oceans serve as a good indicator of the real impact of climate change because compared to air temperatures, they are less affected by seasonal changes and day-to-day weather cycles.
'A world rapidly warming': The past eight years were the eight warmest on record for planet (Photo by Carl Court/Getty Images) Carl Court/Getty Images The UK's Met Office has issued an amber heat warning for the next four days with temperatures expected to hit 37C in some parts of the country. MERTHYR TYDFIL, WALES - AUGUST 11: An aerial view as the water level sits low at Pontsticill Reservoir during a heat wave on Augnear Merthyr Tydfil, Wales. In terms of energy, the amount of heat added to the oceans in 2022 is equivalent to 100 times the total global electricity generation last year, the researchers said. “The state of our oceans can measure the world’s health, and judging by the updated oceanic observations … we need a doctor,” the team of authors said in an accompanying press release. Published in the journal Advances in Atmospheric Sciences on Wednesday, the study looked at temperatures from the ocean surface to 2,000 meters (6,560 feet) deep, examining data going back to the 1950s. The world’s oceans were the warmest on record for the fourth year in row in 2022, a troubling sign of the climate crisis caused by humans pumping heat-trapping gases into the atmosphere.Ī study by an international team of scientists from 16 institutes worldwide found that the five hottest years for oceans all happened in the past six years and that the speed at which oceans are warming is getting increasingly fast.
