According to scientists, we underestimated the quantity of heat absorbed by the world's oceans. Previous estimates suggested that these vast bodies of water had collectively absorbed more than 90% of the excess thermal energy.
The researchers found that the oceans have taken in 13 zettajoules of heat energy each year between 1991 and 2016.
The study was funded by the National Oceanic and Atmospheric Administration and the Princeton Environmental Institute.
"If we think the ocean is warming more than we thought, it means the Earth is warming more than we thought, and that means the Earth is more sensitive to our emissions", lead study author Laure Resplandy, an assistant professor of geosciences at Princeton, told Business Insider. "Our data show that it would have warmed by 6.5 degrees Celsius [11.7 degrees Fahrenheit] every decade since 1991".
A report from the U.N. Intergovernmental Panel on Climate Change earlier this month called for "rapid, far-reaching and unprecedented changes" to limit global warming to 1.5 degrees Celsius instead of 2 degrees, in order to offer the best chance of protecting people, property and natural ecosystems - and "ensuring a more sustainable and equitable society".
"If we think that the ocean is getting hotter than we think, it means that the Earth is warming more than we think and that it is more sensitive to our emissions", said the study's lead author, Business Insider. The IPCC is the leading global body for the assessment of climate change, and its evaluations form the backbone of the technical guidelines used by policymakers. (3.6?), it is all but certain that society will face widespread and risky consequences of climate change. "This is a new complementary method, and the results are quite compatible with our estimates for the most part", he wrote in an email.Dr. Resplandy said her work did not upend the I.P.C.C. report's warnings that humanity has only a couple of decades to ward off some of climate change's most catastrophic effects."It doesn't change the results", she said.
"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. Global temperature records were spotty before 2007, when an worldwide consortium began a program, known as Argo, creating an worldwide network of ocean-temperature-measuring instruments. These levels increase as the ocean warms and releases gases.
