NASA Stumped – Deep Oceans Have NOT Warmed Since At Least 2005

NASA Stumped – Deep oceans have not warmed since at least 2005 (Ice Age Now, Oct 8, 2014):

Oops – Bad news for alarmists – The deep ocean may not be hiding heat after all – How to explain the 18-year hiatus in “global warming” now?

Deep oceans have “not warmed measurably”

According to NASA, “the cold waters of Earth’s deep ocean have not warmed measurably since 2005, leaving unsolved the mystery of why global warming appears to have slowed in recent years.”

“When scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013, they found that “the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably,” the space agency announced in a press release on Monday.

Temperatures in upper oceans not rising fast enough to account for stalled air temperatures

“In the 21st century, [so-called] greenhouse gases have continued to accumulate in the atmosphere just as they did in the 20th century,” the press release said. “But global average surface air temperatures have stopped rising in tandem with the gases. The temperature of the top half of the world’s oceans — above the 1.24-mile mark — is still climbing, but not fast enough to account for the stalled air temperatures.”

“This unfortunate discovery represents a major problem for the climate alarmists because the “missing heat” supposedly hiding in the deep oceans has long been their favoured explanation as to why there has been no measured “global warming” for the last 18 years,” writes James Delingpole on

In February of this year, Gerald Meehl of the National Center for Atmospheric Research (NCAR) told National Geographic that “Strong trade winds are bringing cooler water to the surface in the equatorial Pacific and mixing more heat into the deeper ocean.”

National Geographic helpfully summarised Meehl’s words, saying that “the missing heat from global warming is being stored in a deeper warm pool in the western Pacific.”

And in October 2013, NCAR’s Kevin Trenberth, Godfather of the “missing heat hiding in deep ocean” theory, had this to say on Bloomberg.

In fact, there is mounting evidence that deeper regions of the ocean, down to 2000 meters, are absorbing heat faster than ever, said Trenberth. The oceans began taking on significantly more heat at around the same time the surface warming began to slow in 1998. even jumped on the bandwagon.

Global warming is still with us, it’s just hiding temporarily,” the weather website announced just two months ago. “The apparent slowdown in the Earth’s surface warming in the last 15 years could be due to that heat being trapped in the deep Atlantic and Southern Ocean.”

How much sea level rise is due to deep warming? “The answer is — not much.”


“The combination of satellite and direct temperature data gives us a glimpse of how much sea level rise is due to deep warming,” said JPL’s William Llovel, lead author of the study published Sunday in the journal Nature Climate Change. “The answer is — not much.”

The study took advantage of the fact that water expands as it gets warmer. The sea level is rising because of this expansion and the water added by glacier and ice sheet melt.

The JPL scientists used data from the Argo buoys, NASA’s Jason-1 and Jason-2 satellites, and the agency’s Gravity Recovery and Climate Experiment (GRACE) satellites. From the total amount of sea level rise, they subtracted the amount of rise from the expansion in the upper ocean, and the amount of rise that came from added meltwater. The remainder represented the amount of sea level rise caused by warming in the deep ocean.

Deep ocean warming contributed virtually nothing to sea level rise

The remainder was essentially zero. Deep ocean warming contributed virtually nothing to sea level rise during this period.

Essentially zero!
