Climate Change is Causing Oceans to Absorb more Heat than we Estimated

Knowing how hot the ocean is getting, and how fast that temperature is rising, helps scientists understand more about human-impacted climate change.

Seas retain 90% of the overabundance heat caught on the planet's atmosphere, as indicated by the National Oceanographic and Atmospheric Association (NOAA). "This is definitely something that should and will be taken into account in the next report".

For each year during the past quarter century, the world's oceans have absorbed an amount of heat energy that is 150 times the energy humans produce as electricity annually, according to a study led by researchers at Princeton and the Scripps Institution of Oceanography at the University of California-San Diego.

As there have been patches in time where the ocean's temperature hasn't been recorded, as well as incomplete or differing measurements, scientists have said that the figure has only just been measured accurately. The findings would need to be reproduced in coming years to gain widespread acceptance throughout the scientific community. "In comparison, the estimate of the last IPCC assessment report would correspond to a warming of only 4 degrees Celsius (7.2 degrees Fahrenheit) every decade". Specifically, that means it will be more challenging to avoid flooding from sea level rise in coastal cities, violent hurricanes, and the death of almost all of Earth's coral reefs.

Since 2007, scientists have been able to rely on a system of nearly 4,000 Argo floats that record temperature and salinity in the oceans around the world.

As well as potentially making it more hard to keep warming below 1.5 or even 2C this century, all that extra heat going into the oceans will prompt some significant changes in the waters. But for climate scientists, the answer has serious consequences. Keeping those temperatures down requires cutting the amount of greenhouse gases pumped into the atmosphere. Coastal flooding, food shortages, and a mass die-off of coral reefs could be upon us by 2040. There are about 3,800 such pieces of equipment in waters around the globe that provide the publicly available information.

"We thought that we got away with not a lot of warming in both the ocean and the atmosphere for the amount of Carbon dioxide that we emitted", she is quoted as saying. If they did, they would be more careful with nature and the environment, especially now, when we know that climate change has become a big threat for all of us. "When you average over things, you beat down the error". The I.P.C.C. report showed that scientists may have been underestimating the severity of the world's present climate trajectory.The new ocean temperature estimates, if proven accurate, could be another indication that the global warming of the past few decades has exceeded conservative estimates and has been more closely in line with scientists' worst-case scenarios.The researchers used a new approach that derived ocean temperatures by measuring the levels of carbon dioxide and oxygen in the atmosphere.Those gases dissolve in ocean waters, but the amount the ocean can hold depends on its temperature.
