There is heat in the sea and scientists are worried

An anonymous reader quoted a BBC report: June and the first few days of July were the hottest on record, according to the World Meteorological Organization (WMO). Residents of the southern US and southern Europe are enduring extreme heat warnings, wildfires and deteriorating air quality. However, records are being broken not only on land but also in water. According to the Copernicus Climate Change Service report, global ocean sea surface temperatures were warmer than last June, with satellite readings “off the charts”, particularly in the North Atlantic. Last month, the US National Oceanic and Atmospheric Administration (NOAA) set a record The biggest difference between the expected and the actual sea surface temperature. Water temperatures around Florida were particularly warm. Scientists have been tracking a large continuous sea warming along the west coast of the United States and Canada since its inception in May.

While warming has eased in the north-east Atlantic, another appears to be intensifying in the western Mediterranean, particularly in the Strait of Gibraltar, according to non-profit science organization Mercator Ocean International. This week, temperatures along the coasts of southern Spain and North Africa were 2-4C (3.6-7.2F) warmer than this year, with some places 5C (9F) above the long-term average. High sea temperatures were observed in areas near Ireland, the United Kingdom and the Baltic Sea, as well as New Zealand and Australia. Recently, scientists have suspected a heat wave in the Labrador Sea south of Greenland. “These massive tidal waves appear in different areas of the ocean suddenly at the beginning of the year, very strong and developing from large areas,” said Mercator Ocean Oceanographer Carina von Schuckmann.

Carlo Buontempo, director of the European Union’s Copernicus Climate Change Service, said that scientists expect a large temperature change in the Pacific Ocean associated with El Nino weather, the planet’s warming weather is just beginning, although NOAA is monitoring a severe heat wave in the Gulf of Alaska, which has been sitting on the coast since the end of 2022, but see that there is an anomaly in northern Poland. Scientists are still trying to fully understand the cause. […] More broadly, experts say the persistence of recent marine heat waves is a worrying sign of how climate change is unfolding, along with heat waves on land, unusual melting of ice caps in the Himalayas and loss of sea ice. According to von Schuckmann, even if humans stopped emitting carbon dioxide into the atmosphere tomorrow, the oceans would continue to warm for many years. “As a climate scientist, I am concerned that we are more than we think.”
