Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research, the federal government’s center for understanding weather and climate. “The global warming aspect relates to the fact that the oceans are warmer, and the air above them is more moist.'

'Over 90 percent of the energy currently in the ocean is caused by climate change,' Trenberth says.

Study finds the deep oceans [below 2000 meters]cooled from 2005-2013, debunking the convenient excuse that Trenberth's AGW 'missing heat' has been hiding in the deep oceans. According to the authors, this deep ocean cooling caused a global sea level decrease of -0.13 mm/yr from 2005-2013. 

As the paper notes, this is a reversal from the deep ocean warming from the 1990's to 2005, which led to a sea level rise of +0.11 mm/yr during that period, but has reversed since 2005 to deep ocean cooling and a negative contribution to sea levels. Thus, there is no evidence of the AGW "missing heat" hiding in the deep oceans as many warmists have claimed. 

Even though the heat content of the upper oceans has slightly warmed 0.09C over the past 55 years [Levitus et al 2012], this is also not nearly enough to explain the alleged AGW "missing heat." Therefore, the "missing heat" is missing from both the upper and lower oceans. 

Thirdly, since there has been no statistically-significant warming of the atmosphere [troposphere] over the past 18-26 years during the so-called "pause" or "hiatus", the AGW "missing heat" is missing from the atmosphere as well. 

There is one inescapable conclusion: The "missing heat" is nowhere to be found in Earth's atmosphere or oceans, and has escaped to space, or never existed in the first place [except in computer models]. Indeed, measurements of outgoing longwave radiation to space [infrared from greenhouse gases] have increased over the past 62 years, not decreased as predicted by models from the rise in greenhouse gases.

'Naturally occurring changes in winds, not human-caused climate change, are responsible for most of the warming on land and in the sea along the West Coast of North America over the last century, a study has found. The analysis challenges assumptions that the buildup of greenhouse gases in the atmosphere has been a significant driver of the increase in temperatures observed over many decades in the ocean and along the coastline from Alaska to California.'

'If global warming had been the most powerful influence on land and sea temperatures, those temperatures would have been different, the study's authors said. Most of the warming in the region occurred before 1940, when greenhouse gas concentrations were lower and winds were weaker, the study found. In contrast, winds have strengthened since 1980 and coastal ocean cooled, even as the rise in greenhouse gases has accelerated.'

A new paper finds the deep oceans have cooled contrary to alarmist claims of deep ocean warming by Trenberth's "missing heat" from carbon dioxide. Trenberth's theory, one of at least 14 excuses for the ~18 year 'pause' of global warming, now appears to be dead in the water.

Curry: 'With regards to climate science, the biggest concern that I have is the insistence on ‘the facts.’ This came up during my recent ‘debate’ with Kevin Trenberth. I argued that there are very few facts in all this, and that most of what passes for facts in the public debate on climate change is: inference from incomplete, inadequate and ambiguous observations; climate models that have been demonstrated not to be useful for most of the applications that they are used for; and theories and hypotheses that are competing with alternative theories and hypotheses.'
