OCEAN SURFACE TEMPERATURE SMASHES RECORD, REACHES 21.1 DEGREES

Sat 08 Apr 2023:

The global ocean surface temperature has reached an all-time high since satellite records first started. According to preliminary data from the National Oceanic and Atmospheric Administration (NOAA), the average temperature at the ocean’s surface has been 21.1 degrees Celsius since the beginning of April, the Guardian reported.

As a result, the temperatures surpassed the previous record high of 21 degrees set in 2016. Globally, rising ocean temperatures are causing marine heatwaves.

Prof Matthew England, a climate scientist at the University of New South Wales, said, “The current trajectory looks like it’s headed off the charts, smashing previous records.”

Three years of La Nina conditions in the wide tropical Pacific, which cause a more intense hurricane season, have assisted in lowering temperatures. This has reduced the impact of increasing greenhouse gas emissions.

A probable El Nino trend in the tropical Pacific later this year could boost the likelihood of extreme weather and further threaten world heat records, according to experts. The northern US and Canada are seeing drier and warmer weather than typical as a result of El Nino conditions.

Dr Mike McPhaden, a senior research scientist at NOAA, said, “The recent ‘triple dip’ La Niña has come to an end. This prolonged period of cold was tamping down global mean surface temperatures despite the rise of greenhouse gases in the atmosphere.”

“Now that it’s over, we are likely seeing the climate change signal coming through loud and clear.”

According to NOAA data, El Nino, which occurred from 2014 to 2016, coincided with the second-warmest global averaged ocean temperatures. The data is primarily generated by satellite observations, but it is supplemented by measurements taken by boats and buoys. The statistics exclude the polar regions.
