New dangerous heating level in the world’s oceans in 2019: floods, wildfires, inexorable rise in sea level.
The heat in the world’s oceans reached a new record level in 2019.
Oceans are clearest measure of climate crisis as they absorb 90% of heat trapped by greenhouse gases and are showing “irrefutable and accelerating” heating of the planet.
The new analysis shows the past five years are the top five warmest years recorded in the ocean and the past 10 years are also the top 10 years on record.
The greenhouse gases are emitted by fossil fuel burning, forest destruction and other human activities.
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.
Ocean temperatures hit record high as rate of heating accelerates
Hotter oceans lead to more severe storms and disrupt the water cycle, meaning more:
- worst tornados,
- droughts wildfires,
- more raining water-bombs,
- inexorable rise in sea level,
- more natural disasters.
Prof John Abraham at the University of St Thomas, in Minnesota, said:
“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 Michael Mann, at Penn State University, US, said:
“We found that 2019 was not only the warmest year on record, it displayed the largest single-year increase of the entire decade, a sobering reminder that human-caused heating of our planet continues unabated,”
The analysis, published in the journal Advances In Atmospheric Sciences, uses ocean data from every available source.
Most data is from the 3,800 free-drifting Argo floats dispersed across the oceans, but also from torpedo-like bathythermographs dropped from ships in the past.
