A new study published in the journal Geophysical Research Letters says that in the past 15 years we've undergone "the most sustained warming trend."
The researchers attribute this "missing heat" phenomena to the fact that about 90% of overall global warming goes into heating the oceans, and the oceans have been cooking.
The myth that global warming has slowed--which is frequently cited by climate deniers and perpetuated by "fundamentally flawed" studies that do not account for the warming of deep ocean waters--has had the dangerous effect of "lull[ing] many people into a false and unwarranted sense of security," writes Skeptical Science, "with many people wrongly believing global warming has paused when in reality it has accelerated."
The article, "Distinctive climate signals in reanalysis of global ocean heat content," explains how the strength of recent La Nina events has caused a large amount of heat from global warming to be transferred to the deep oceans. According to the study, "In the last decade, about 30% of the warming has occurred below 700 m, contributing significantly to an acceleration of the warming trend."
Meanwhile, the warming at the surface has slowed down in recent years due to subsequent "sharp cooling" events, such as volcanic eruptions and El Nino patterns.
Leading climatologist Dr. Jeff Masters of Weather Undergroundexplains that, despite this apparent slowdown, the "total amount of heat going in the atmosphere/oceans/surface has continued unabated."
As report co-author Kevin Trenberth explained to Skeptical Science, "It means less short term warming at the surface but at the expense of a greater earlier long-term warming, and faster sea level rise," because the extra heat energy causes ocean water to expand.
"The global warming end result will be the same," writes Skeptical Science, "but the pattern of surface warming over time may be different than we expect." They conclude:
Most importantly, everybody (climate scientists and contrarians included) must learn to stop equating surface and shallow ocean warming with global warming. [...] We need to measure global warming by accounting for all changes in global heat content, including the deeper oceans. Otherwise we can easily fool ourselves into underestimating the danger of the climate problem we face.

Trump and Musk are on an unconstitutional rampage, aiming for virtually every corner of the federal government. These two right-wing billionaires are targeting nurses, scientists, teachers, daycare providers, judges, veterans, air traffic controllers, and nuclear safety inspectors. No one is safe. The food stamps program, Social Security, Medicare, and Medicaid are next. It’s an unprecedented disaster and a five-alarm fire, but there will be a reckoning. The people did not vote for this. The American people do not want this dystopian hellscape that hides behind claims of “efficiency.” Still, in reality, it is all a giveaway to corporate interests and the libertarian dreams of far-right oligarchs like Musk. Common Dreams is playing a vital role by reporting day and night on this orgy of corruption and greed, as well as what everyday people can do to organize and fight back. As a people-powered nonprofit news outlet, we cover issues the corporate media never will, but we can only continue with our readers’ support. |
