Startling new research finds large buildup of heat in the oceans, suggesting a faster rate of global warming

The world’s oceans have been soaking up far more excess heat in recent decades than scientists realized, suggesting that Earth could be set to warm even faster than predicted in the years ahead, according to new research published Wednesday.

Over the past quarter-century, Earth’s oceans have retained 60 percent more heat each year than scientists previously had thought, said Laure Resplandy, a geoscientist at Princeton University who led the startling study published Wednesday in the journal Nature. The difference represents an enormous amount of additional energy, originating from the sun and trapped by Earth’s atmosphere — the yearly amount representing more than eight times the world’s annual energy consumption.

In the scientific realm, the new findings help resolve long-running doubts about the rate of the warming of the oceans before 2007, when reliable measurements from devices called “Argo floats” were put to use worldwide. Before that, differing types of temperature records — and an overall lack of them — contributed to murkiness about how quickly the oceans were heating up.

The higher-than-expected amount of heat in the oceans means more heat is being retained within Earth’s climate system each year, rather than escaping into space. In essence, more heat in the oceans signals that global warming is more advanced than scientists thought.

SkS in the News...

In his Op-ed, In praise of 'real' science, published in the Times Colonist (Victoria, BC), Geof Johnson wrote:

In the online journal Skeptical Science, John Cook, a research assistant professor at the Centre for Climate Change Communication at George Mason University, writes: “The assertion that humans are, one way or another, at the root of global warming is the position of the academies of science from 80 countries.” 


Quote of the Week

 “We thought that we got away with not a lot of warming in both the ocean and the atmosphere for the amount of CO2 that we emitted,” said Resplandy, who published the work with experts from the Scripps Institution of Oceanography and several other institutions in the United States, China, France and Germany. “But we were wrong. The planet warmed more than we thought. It was hidden from us just because we didn’t sample it right. But it was there. It was in the ocean already.”

SkS Spotlights...

Climate Action 100+

Climate Action 100+ is a five-year initiative led by investors to engage systemically important greenhouse gas emitters and other companies across the global economy that have significant opportunities to drive the clean energy transition and help achieve the goals of the Paris Agreement. Investors are calling on companies to improve governance on climate change, curb emissions and strengthen climate-related financial disclosures.

Investor representatives from AustralianSuper, California Public Employees’ Retirement System (CalPERS), HSBC Global Asset Management, Ircantec and Manulife Asset Management have helped to lead the design and development of Climate Action 100+. The initiative is coordinated by five partner organisations: Asia Investor Group on Climate Change (AIGCC); Ceres; Investor Group on Climate Change (IGCC); Institutional Investors Group on Climate Change (IIGCC); and Principles for Responsible Investment (PRI). It builds on the successful investor engagement programmes coordinated by the partner organisations over a number of years.

Climate Feedback Reviews

Washington Post accurately describes ocean warming study with potential implications for future carbon budget

Climate Feedback 44

Climate Feedback asked a team of scientists to analyze the article, Startling new research finds large buildup of heat in the oceans, suggesting a faster rate of global warming by Chris Moody & Brady Dennis, Energy & Environment, Washington Post, Oct 31, 2018

Three scientists analyzed the article and estimate its overall scientific credibility to be 'high'.

A majority of reviewers tagged the article as: AccurateInsightfulSound reasoning.

Review Summary 

This article in The Washington Post covers a new study estimating the amount of heat energy that has accumulated in the ocean in recent decades. Such estimates have been limited because the most complete network of ocean temperatures did not exist until the 2000s. The new study uses an indirect method, instead relying on changes in atmospheric gases caused by warmer oceans. This method leads to a larger estimate of the ocean warming that resulted from human activities.

Scientists who reviewed the article found that it did a good job of describing the study, while noting that the study’s conclusions (and implications) require additional investigation. In particular, discussion among scientists has focused on clarifying what impact this study’s results have on our understanding of climate sensitivity (how much warming occurs from a given amount of greenhouse gas emissions) and, consequently, how much the world can emit before reaching 2 °C warming.

  1. Well, Well!  It seems that the SkS "myth" titled Temp record is unreliable is really not a myth at all according to the third paragraph which states:

    In the scientific realm, the new findings help resolve long-running doubts about the rate of the warming of the oceans before 2007, when reliable measurements from devices called “Argo floats” were put to use worldwide. Before that, differing types of temperature records — and an overall lack of them — contributed to murkiness about how quickly the oceans were heating up.

    So despite the fact since the 1980s, the AGW community has preached the importance of heeding the "experts" with their "overwhelming evidence" and 97% consensus about human-caused global warming, reliable temperature measurements did not exist before the year 2007. This is by their own statements and not those of the contrarions. Therefore, the science concerning climate change is not settled and it would be grossly unethical to impose more taxes and regulations on the citizens of any nation under the pretense of saving the planet from AGW.  This is especially true considering the fact that despite all of this global warming, people in the northeastern and midwestern US have seen record low temperatures for the past three or four winters. They simply cannot afford another tax on top of their already high heating bills.

    [JH] Sloganeering snipped. By the way, the heat content of the ocean is an entirely different subject matter than the temperature of the atmosphere at the surface of the Earth. You can use this site's Climate Science Glossary to learn what each term means.

    Please note that posting comments here at SkS is a privilege, not a right.  This privilege can be rescinded if the posting individual treats adherence to the Comments Policy as optional, rather than the mandatory condition of participating in this online forum.

    Please take the time to review the policy and ensure future comments are in full compliance with it.  Thanks for your understanding and compliance in this matter.

  2. JayCharles,

    The global surface temperature record is the 'Temperature Record' addressed by the SkS myth debunking item you refer to.

    The ocean heat content is a related matter. However, any correction or new learning regarding ocean heat content would not change the global average surface temperature data.

    I hope that helps you better uderstand this issue.

    What is undeniably unethical is for a portion of any current generation of humanity to personally benefit from an unsustainable activity that undeniably harms others, particularly an activity that harms future generations (generations that will not be able to continue to benefit from the activity because it is unsustainable - the burning of buried ancient hydrocarbons has a finite future).

    Gradually making the unacceptable activity more expensive, a progressively increased fee on the carbon, is actually a slower correction of the harmful activity than the future generations would prefer to see. It is an action that makes the harm to future gemerations larger than it would be if more aggressive corrective actions were implemented.

    And the longer and slower the correction is, the more jarring a future desperate correction may need to be, with even more future harm done. Especially if global geo-engineering action is thought to be the way to address a future emergency that was avoidable, but was not avoided because so many people in the previous generations had developed a powerful greedy resistance to being corrected.

    And the less fortunate do need to be helped, but excusing fossil fuel burning is not helpful.

    [DB] The poster you refer to is one of 3 dozen fake account sock puppets run by user "cosmoswarrior".  No further responses to it are warranted, as it's sole purpose for existence is to waste the time of as many as possible, for as long as possible.

    It's posting privileges have been revoked (like all that came before it), as will those of future similar, ignorant iterations.
