For The Past Year, Global Ocean Temperatures Has Set New Records On A Daily Basis.

According to new data, the world’s oceans have now been subjected to an unprecedented year of heat, with new temperature records being smashed every day.

Global water surface temperatures began breaking daily records in mid-March last year, according to data from the National Oceanic and Atmospheric Administration (NOAA) and the University of Maine’s Climate Reanalyzer, raising fears about marine life and extreme weather worldwide.

“The amplitude by which previous sea surface temperature records were beaten in 2023, and now again in 2024, is remarkable,” said Joel Hirschi, associate head of marine systems modelling at the National Oceanography Centre in the United Kingdom.

Gregory C. Johnson, a NOAA oceanographer, reported that the global average ocean temperature in 2023 was 0.25 degrees Celsius higher than the previous year. That increase “is equivalent to about two decades’ worth of warming in a single year,” he told CNN. “So it is quite large, quite significant, and a bit surprising.”

According to scientists, human-caused global warming, along with El Niño, a natural climate trend characterized by higher-than-average water temperatures, is accelerating  heat.

The biggest repercussions are for marine life and global weather. As the global waterwarms, hurricanes and other extreme weather phenomena, such as blistering heat waves and heavy rains, may gain more force.

High temperatures are already wreaking havoc on coral. In March, based on aerial observations, authorities declared that Australia’s Great Barrier Reef is witnessing its seventh mass bleaching episode.

Bleaching happens when heat-stressed corals release the algae that dwell in their tissue and serve as a food supply. If water temperatures continue too high for too long, corals will starve and die.

Data from NOAA’s Coral Reef Watch program suggest that the crisis extends far beyond Australia, with the world potentially facing a fourth worldwide mass coral bleaching event in the coming months.

Ocean heat creates the conditions for more powerful hurricanes. “The warmer the ocean, the more energy to fuel storms is available,” said Karina von Schuckmann, an oceanographer at Mercator Ocean International in France.

Temperatures in the North Atlantic, an water area important for storm generation, have been unusual, startling some scientists who are still investigating the specific causes.

“At times, the records (in the North Atlantic) have been broken by margins that are virtually statistically impossible,” Brian McNoldy, a senior research associate at the University of Miami Rosenstiel School, said to CNN.

If water temperatures remain high in the second half of 2024 and a La Niña event intensifies the Atlantic hurricane season, “this would increase the risk of a very active hurricane season,” Hirschi explained.

The oceans contain around 90% of the world’s excess heat generated by burning planet-heating fossil fuels. “Measuring water warming allows us to track the status and evolution of planetary warming,” Schuckmann stated in an interview with CNN. “The ocean is the sentinel for global warming.”

El Niño is expected to weaken and fade in the coming months, perhaps reducing record water temperatures if La Niña replaces it.

“In the past, surface temperature values have decreased after the passage of El Niño,” Schuckmann said. However, she cautioned that it is now hard to forecast when water temperatures will fall below record levels.

While natural climatic variability will cause water temperatures to vary, NOAA’s Johnson predicts that in the long run, they will “continue to break records as long as greenhouse gas concentrations in the atmosphere rise.”
