Ocean temperatures set to break records in 2021
A report released in January 2022 by a group of 14 international research teams including the United States, China, and Italy, stated that the global warming caused by CO2 and CH4 has increased due to the rise in sea temperature. The ocean temperatures have been continuously rising for the last three years, making 2021 the warmest year on record since modern ocean observations began. The report highlights that over 90% of global warming occurs in the oceans, and ocean heat content changes are the best indicators of global warming. The main cause of ocean warming is attributed to the increase in greenhouse gases, and its effects could last for at least a century. The report also mentions the influence of natural events like La Niña, which is a natural climate phenomenon, on ocean warming. However, the impact of La Niña is temporary and does not affect the long-term impact of human activities on climate change. The report also warns of the possibility of extreme weather events continuing due to global warming.
