From the NATIONAL OCEANOGRAPHY CENTRE, UK and the “search for Bigfoot Trenberth’s missing heat” department comes this bit of news that completes part of the geothermal heat loss puzzle. Mystery of heat loss from the Earth’s crust has been solved The first discovery of a new type of hydrothermal vent system in a decade helps…
…that some of the warming nearer to the surface came from the deep ocean. Guest Post by Bob Tisdale The paper is Liang et al. (2015) Vertical Redistribution of Oceanic Heat Content. The abstract reads (my boldface): Estimated values of recent oceanic heat uptake are of order of a few tenths of a W/m2, and…
Guest Post by Werner Brozek, Edited by Just The Facts: The comment referred to in the title is the following by Kevin Trenberth regarding heat in the deep oceans: “The centre of action is the Pacific Ocean but the main places where heat goes deep into the ocean are the Atlantic and Southern Oceans rather…
Guest Post by Bob Tisdale UPDATE (Dec. 24, 2014): Looks like someone at NCAR wasn’t as open minded as I thought. The links at Kevin Trenberth’s media page to my blog have been removed. Good thing I archived it. # # # # We’ve discussed the work and opinions of NCAR’s Dr. Kevin Trenberth in…
Rebuttal to Chen and Tung (2014) highlighted in “Cause for ‘The Pause’ #38 – Cause of global warming hiatus found deep in the Atlantic Ocean” Numerous scientific papers have reported the hiatus in global surface warming will end with the next El Niño event. But according to a new paper by Chen and Tung published…
From the University of Washington and the department of Trenberth’s missing heat comes a claim that we’ll have to wait another 15 years for global warming to resume. Sounds like a goalpost mover to me. The Oceans that Slowed 21st Century Global Warming Why did the rapid global warming that characterized the latter part of…
People send me stuff. Yesterday I got a note suggesting I have a look at what NOAA/NCDC’s “climate at a glance” was showing for trends in the 21st century so far. I decided to take a look.
Date: January 31, 2014 Subject: Your Blog Post at SkepticalScience and an Invitation from WattsUpWithThat From: Bob Tisdale To: Kevin Trenberth – NCAR Dear Kevin: I note that you were co-author of the SkepticalScience blog post Warming oceans consistent with rising sea level & global energy imbalance along with Dana Nuccitelli and Rob Painting. The…
From the “settled science” department. It seems even Dr. Kevin Trenberth is now admitting to the cyclic influences of the AMO and PDO on global climate. Neither “carbon” nor “carbon dioxide” is mentioned in this article that cites Trenberth as saying: “The 1997 to ’98 El Niño event was a trigger for the changes in the…
…then why do the vertical mean temperature anomalies (NODC 0-2000 meter data) of the Pacific Ocean as a whole and of the North Atlantic fail to show any warming over the past decade, a period when ARGO floats have measured subsurface temperatures, providing reasonably complete coverage of the global oceans? See Figure 1. Or, in…
We discussed the Trenberth and Fasullo (2013) paper “An Apparent Hiatus in Global Warming?” in the recent post Trenberth and Fasullo Try to Keep the Fantasy Alive. Since then, Dana Nuccitelli published a post at TheGuardian—cross posted at SkepticalScience—extolling the greatness of Trenberth and Fasullo (2013). So far, the team at RealClimate and Joe Romm…
Trenberth and Fasullo published a paper “An Apparent Hiatus in Global Warming?” last week in the new online journal Earth’s Future. Judith Curry briefly introduced the paper in her December 7, 2013 post Week in review (Thanks, Judith.) From the last sentence of the abstract, Trenberth and Fasullo (2013) argues that: Global warming has not…
More settled science: these whirlpools transport vast amount of water and heat vertically in the ocean, somewhat like hurricanes do for the atmosphere. It is fun to imagine “Trenberth’s missing heat” being sucked down one of these. Via Yahoo News: Satellites have shown two mysterious ‘black hole’ whirlpools in the South Atlantic ocean – ultra…
Guest Post by Willis Eschenbach I’ve been investigating one of my favorite datasets in the last few days, the CERES satellite-based top-of-atmosphere (TOA) radiation dataset. In particular, I’ve taken month-by-month global and hemispheric averages of the data. The dataset consists of observations of three variables—downwelling solar radiation, upwelling longwave (infrared) radiation, and upwelling shortwave radiation…
OVERVIEW Rob Painting of SkepticalScience recently published the post A Looming Climate Shift: Will Ocean Heat Come Back to Haunt Us? Many of you will find his post entertaining. But this post is not about the SkepticalScience post. This post discusses the recent paper Rob Painting cited: Meehl et al (2013) “Externally forced and internally…
Update: At the suggestion of one of the readers at the cross post at WUWT, I’ve rewritten the second paragraph after Figure 3. Thanks, richard verney. ######## In response to the May 19, 2013 op-ed Overheated rhetoric on climate change doesn’t make for good policies by Lamar Smith (Chairman of the House Committee on Science,…
Update 2: A number of typos were found in this post. I’ve corrected them here and in the pdf version. A revised pdf copy is available here. I’ve removed the old version from WordPress. #### Note: A typo was found and corrected in the post. I’ll update the pdf version later today. ##### Dear Members of…
Roger Pielke Sr. was quoted in David Appell’s recent article Whither global warming? Has global warming slowed down? over at the Yale Forum on Climate Change & The Media. That portion of the article reads: About 90 percent of this extra energy goes into the oceans. But meteorologist Roger Pielke Sr. of the University of…
We discussed Dr. Roy Spencer’s post More on Trenberth’s Missing Heat in my recent post and in the cross post at WattsUpWithThat. One of the points Roy made: a change in ocean heat content is presented in terms that look impressive: Joules times 10^22 or Joules with oodles of trailing zeroes. However, in terms that…
In the post Trenberth Still Searching for Missing Heat, we discussed the recent Balmaseda et al (2013) paper “Distinctive climate signals in reanalysis of global ocean heat content”, of which Kevin Trenberth was a coauthor. Dr. Roy Spencer also has a recent post on that paper. I’ve cross posted Roy’s post following this introduction. Roy…
A paper published August 20th in Geophysical Research Letters finds from newly deployed observation systems that the Southern Oceans show an annual net heat loss of -10 Wm-2. Key Points Southern Ocean air-sea fluxes are under-observed, leading to large uncertainty The first year-long air-sea flux observations quantify an annual cycle Shows seasonal cycle, small annual…
Guest Post by Willis Eschenbach Over at Judith Curry’s excellent blog there’s a discussion of Trenberth’s missing heat. A new paper about oceanic temperatures says the heat’s not really missing, we just don’t have accurate enough information to tell where it is. The paper’s called Observed changes in top-of-the-atmosphere radiation and upper-ocean heating consistent within…
Via Eurekalert and Wiley-Blackwell The human cause of climate change: Where does the burden of proof lie? Dr. Kevin Trenberth advocates reversing the ‘null hypothesis’ The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs…
Guest post by Bob Fernley-Jones by Bob Fernley-Jones AKA Bob_FJ CAUTION: This is written in Anglo-Oz English. Here is the diagram as extracted from their 2009 paper, it being an update of that in the IPCC report of 2007 (& also 2001): The unusual aspect of this diagram is that instead of directly showing radiative Heat…
Torpedoing Of The Use Of The Global Average Surface Temperature Trend As The Diagnostic For Global Warming By Dr. Roger Pielke Senior There is a new paper by Gerald Meehl of NCAR and other collaborators that has been announced in the media; i.e. see in the International Business Tribune [h/t to Watts Up With That] Global Warming on…
April to June 2011 NODC Ocean Heat Content Anomalies (0-700Meters) Update and Comments Guest post by Bob Tisdale A NEW APPEARANCE Due to the noise in the Ocean Heat Content anomaly data for some of the ocean basins, I’ve added 13-month running average filters to the long-term graphs.
From the National Center for Atmospheric Research/University Corporation for Atmospheric Research an explanation for Global Ocean Heat Content Is Still Flat. Key point from the press release: Observations from a global network of buoys showed some warming in the upper ocean, but not enough to account for the global build-up of heat. Although scientists suspected the…
