Jakarta, Klinik Farma – Global ocean temperatures set new temperature records this week, raising concerns about indirect impacts on the planet’s climate, marine life and coastal communities.
Ocean surface temperatures rose to 20.96 degrees Celsius (69.7 degrees Fahrenheit) on July 30, according to data from the European Union Climate Observatory.
This was announced by the representative of the EU climate change service Copernicus. AFPFriday (04/08/2023), the previous record was 20.95 Celsius in March 2016. Meanwhile, the samples tested did not include the polar regions.
A similar trend has been noted in recent months by the US National Oceanic and Atmospheric Administration (NOAA), which uses other data.
It states that the record average sea surface temperature was reached on April 4 this year at 21.06 Celsius, surpassing the previous high of 21.01 Celsius in March 2016. On August 1, the average temperature was 21.03 Celsius, he said.
According to scientists, since the beginning of the industrial age, the oceans have absorbed 90% of the excess heat generated by human activity, and this excess heat continues to accumulate in the form of greenhouse gases, mainly from the burning of oil, gas and coal, and accumulates in the Earth’s atmosphere.
Globally, average ocean temperatures have surpassed the record seasonal heat wave since April.
“Ocean heat waves pose an immediate threat to some marine life,” said Piers Forster of the Center for International Climate at the University of Leeds, UK.
“We are already seeing coral bleaching in Florida as a direct result and I expect the impact to be even greater.”
Warming oceans are also predicted to have other impacts on marine vegetation and wildlife, including the migration of certain species and the spread of invasive species. This could endanger fish stocks and thus undermine food security in some parts of the world.
Warmer oceans are also less able to absorb carbon dioxide (CO2), exacerbating the vicious cycle of global warming.
Warmer temperatures are also likely due to the El Niño phenomenon, which tends to warm the water.
Scientists predict that the worst effects of the current El Niño will be felt at the end of 2023 and will continue in subsequent years.
