Oceans heating faster than previously thought

Among the painful changes India may have to make is to shut coal plants before the end of their economic lives

The researchers reported in the journal Nature Nov. 1 that the world's oceans took up more than 13 zettajoules - which is a joule, the standard unit of energy, followed by 21 zeroes - of heat energy each year between 1991 and 2016. In fact, it's 60% higher than we thought so far.

This new reality suggests that it is even more unlikely that global warming will remain below the maximum of 2 degrees Celsius established in the Paris agreement.

A new report revealed that the ocean is absorbing more heat that can be transferred back to the atmosphere any time.

"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", one of the report's authors, Princeton geoscientist Laure Resplandy.

Scientists like Resplandy are always looking for better data and more precise measurements.

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.

"These estimates all use the same imperfect ocean dataset", they wrote. What's more, the Argo floats don't track much of what happened before 2007.

"Imagine if the ocean was only 30 feet deep", said Resplandy, who was a postdoctoral researcher at Scripps. The researchers used a different way to measure ocean warmth, "an independent estimate by using measurements of atmospheric oxygen and carbon dioxide-levels of which increase as the ocean warms and releases gases-as a whole-ocean thermometer".

The team analyzed oxygen levels in the ocean and carbon dioxide (CO2) at three locations in the lower, middle and upper part of the Earth: the tip of Tasmania in Cape Grim, La Jolla, California, and Alert, Canada, only 800 kilometres from the north pole. If oceans rise faster than forecast, that represents more of an immediate threat to low-lying communities.

The result, the paper's authors said, "suggests that ocean warming is at the high end of previous estimates, with implications for policy-relevant measurements of the Earth response to climate change, such as climate sensitivity to greenhouse gases and the thermal component of sea-level rise". So some squid populations are already swimming to the north in search of cooler water with more oxygen. In North Carolina, many summer flounder have moved 25 miles up the coast, while lobster populations in the Atlantic are increasingly going up toward Maine.

If anything, the findings help explain why we're already seeing so much sea-level rise and why numerous ocean's creatures are seeking refuge in new locations.

Rising ocean temperatures mean seas will rise faster, and sensitive areas such as tropical coral reefs and ice sheets near the poles will become even more damaged.

But she said it's not a reason to lose hope - instead, the findings should serve as a reason to double-down on efforts to save the planet. In a statement, Resplandy said that to slow warming, emissions of carbon dioxide must be reduced by 25 percent from previous estimates. Until then, we have to make sure that waters are kept as clean as possible.
