Ocean temperatures hit record high

The heat in the world’s oceans reached a new record level in 2019, showing “irrefutable and accelerating” heating of the planet, states The Gurdian.

The world’s oceans are the clearest measure of the climate emergency because they absorb more than 90% of the heat trapped by the greenhouse gases, which were emitted by fossil fuel burning, forest destruction and other human activities.

The new analysis shows the past five years are the top 5 warmest years recorded in the ocean and the past 10 years are also the top 10 years on record. The amount of heat being added to the oceans is equivalent to every person on the planet running 100 microwave ovens all day and all night.

“The oceans are really what tells you how fast the Earth is warming. Using the oceans, we see a continued, uninterrupted and accelerating warming rate of planet Earth. This is dire news.”

Prof John Abraham at the University of St Thomas, in Minnesota, US

Hotter oceans lead to more severe storms and disrupt the water cycle, meaning more floods, droughts and wildfires, as well as an inexorable rise in sea level. Higher temperatures are also harming life in the seas, with the number of marine heatwaves increasing sharply.
