Study finds global ocean warming has decelerated 50% over the past 50 years

The currently-favored excuse du jour for no statistically-significant global warming over the past 20 years is that the oceans “ate the man-made global warming.” However, a 2012 paper published in Nature Climate Change torpedoes this notion, finding the global oceans started warming at least 135 years ago just after the Little Ice Age, on or before the historic voyage of the HMS Challenger in the 1870’s. More importantly, the study finds that ocean warming has decelerated 50% over the past 50 years. 

If, as claimed, man-made greenhouse gases are causing the oceans to warm, the opposite would have been expected, namely an acceleration of ocean warming over the past 50 years, beginning in the ~1950’s. The fact that the oceans were warming long before CO2 levels significantly increased, and at a higher rate before 50 years ago, clearly demonstrates ocean warming is a natural recovery from the Little Ice Age, and not due to man-made CO2.

The paper is corroborated by a recent paper finding the oceans have warmed only 0.09C over the past 55 years, a rate of 0.0016C per decade, and a 36% deceleration from the rate of 0.0025 per decade over the past 134 years found by this study.

Further, climate alarmists claim that the “missing heat” is hiding below 1,500 meters deep, but this paper finds the oceans have instead cooled below 1,500 meters over the past 134 years [see third figure below].

In addition, if man-made CO2 was warming the oceans, there should have been an acceleration of steric sea level rise over the past 50 years due to thermal expansion, but no acceleration of sea level rise has been found over the past 203 years.

New Comparison of Ocean Temperatures Reveals Rise over the Last Century Ocean robots used in Scripps-led study that traces ocean warming to late 19th century

A new study contrasting ocean temperature readings of the 1870s with temperatures of the modern seas reveals an upward trend of global ocean warming spanning at least 100 years.

The research led by Scripps Institution of Oceanography at UC San Diego physical oceanographer Dean Roemmich shows a .33-degree Celsius (.59-degree Fahrenheit) average increase in the upper portions of the ocean to 700 meters (2,300 feet) depth. …

University of Reading scientist’s warning over global warming – Reading PostProf Sutton said: “All the evidence makes it clear that leaving the issue of climate change for future generations to deal with is a phenomenally high-risk option.“The report shows that the evidence of human activities affecting climate is increasingly widespread and stronger than ever….“Only under a very ambitious scenario for reducing greenhouse gas emissions is a warming of more than 2C considered to be unlikely.“This report provides the evidence that governments need to take tough decisions on climate change policy.“I hope they will read it carefully and take seriously all its findings…”
