Lack of Global Warming Blamed on Heat Hiding Oceans

Editor's Note:  They ignore the laws of thermodynamics and just assume the heat is stored somewhere.  Heat dissipates. 

"Missing" global heat may hide in deep oceans

(Reuters) - The mystery of Earth's missing heat may have been solved: it could lurk deep in oceans, temporarily masking the climate-warming effects of greenhouse gas emissions, researchers reported on Sunday.
 
Climate scientists have long wondered where this so-called missing heat was going, especially over the last decade, when greenhouse emissions kept increasing but world air temperatures did not rise correspondingly.


The build-up of energy and heat in Earth's system is important to track because of its bearing on current weather and future climate.


The temperatures were still high -- the decade between 2000 and 2010 was Earth's warmest in more than a century -- but the single-year mark for warmest global temperature was stuck at 1998, until 2010 matched it.


The world temperature should have risen more than it did, scientists at the National Center for Atmospheric Research reckoned.


They knew greenhouse gas emissions were rising during the decade and satellites showed there was a growing gap between how much sunlight was coming in and how much radiation was going out. Some heat was coming to Earth but not leaving, and yet temperatures were not going up as much as projected.


So where did the missing heat go?


Computer simulations suggest most of it was trapped in layers of oceans deeper than 1,000 feet during periods like the last decade when air temperatures failed to warm as much as they might have.


This could happen for years at a time, and it could happen periodically this century, even as the overall warming trend continues, the researchers reported in the journal Nature Climate Change.


"This study suggests the missing energy has indeed been buried in the ocean," NCAR's Kevin Trenberth, a co-author of the study, said in a statement. "The heat has not disappeared and so it cannot be ignored. It must have consequences."


Trenberth and the other researchers ran five computer simulations of global temperatures, taking into account the interactions between the atmosphere, land, oceans and sea ice, and basing the simulations on projected human-generated greenhouse gas emissions.


These simulations all indicated global temperature would rise several degrees this century. But all of them also showed periods when temperatures would stabilize before rising. During these periods, the extra heat moved into deep ocean water due to changes in ocean circulation, the scientists said.

Activate (?) your science

Climate Etc.
Judith Curry

We need bold science and bold action.   There is a vital role for governments to play, but equally importantly is the role of academia, civil society, and industry.  Harnessing that collective commitment is underway – but it remains to be seen if changes will be rapid and substantial enough. Her Excellency noted in her powerful opening remarks that there is a significant gap between the accelerating pace of degradation and the rate of effective response.
   
Each of you here can influence the rate of response by activating your science.  - Jane Lubchenco, NOAA Administrator

NOAA Administrator Jane Lubchenco gave the keynote presentation at the recent   International Coral Reef Symposium in Cairns, Australia.   The text of the speech is found here.  Some excerpts:

Scientists – YOU and I ! –  with our knowledge of the threats, consequences, and likelihood success of options for solutions, have a particular responsibility to share our findings broadly, develop useful and useable decision-support tools, team up with local communities and industry partners, and help craft practical solutions.

Your knowledge and your passion are sorely needed.  But your knowledge must be shared in ways that are understandable, credible and relevant to decision-making at multiple levels.  Learning to become bilingual – to speak both the language of science and the language of lay people is a skill more scientists need to learn.  You’ve all heard the phrase ‘learn by doing’?  The same applies to teaching: ‘teach by doing…not by preaching.’

This is, in fact, happening in many parts of the world. Scientists, communities, NGOs, industry and governments are collaborating to develop management solutions that provide for immediate local needs and enable healthy, resilient reefs. These are powerful, hopeful signs, they are simply not at the scale commensurate with the threats.

This is a story of leadership, multidisciplinary and interdisciplinary partnerships across many types of partners, peer learning, and science to develop and implement creative solutions that address food security in the face of climate change and ocean acidification.

The world, its coral reefs and the millions of people that depend upon them need more bold action – action that is science-and ecosystem-based,action that is embraced locally and nationally, action that values tomorrow as well as today. And we need bold science – science that is use-inspired: i. e., it is cutting-edge but relevant and focused on solutions. 

Each of you here can influence the rate of response by activating your science.

I invite you to do more than create new knowledge.  Share it! Put it to use with partners and a sustained engagement.

In short, activate your science.

Donna LaFramboise doesn’t like what Lubchenco had to say:

In Lubchenco’s universe there is apparently no danger of scientists going overboard, of unconsciously biasing their research. She seems to think that earning a scientific degree somehow transforms individuals into infallible beings who will never fall victim to self-delusion, whose judgment will always be impeccable.

The latest issue of Nature Climate Change has an article by Kevin Anderson and Alice Bows entitled A new paradigm for climate change that make similar points:

How climate change science is conducted, communicated and translated into policy must be radically transformed if ‘dangerous’ climate change is to be averted.

We urgently need to acknowledge that the development needs of many countries leave the rich western nations with little choice but to immediately and severely curb their greenhouse gas emissions. But academics may again have contributed to a misguided belief that commitments to avoid warming of 2 °C can still be realized with incremental adjustments to economic incentives. A carbon tax here, a little emissions trading there and the odd voluntary agreement thrown in for good measure will not be sufficient.

Scientists may argue that it is not our responsibility anyway and that it is politicians who are really to blame. The scientific community can meet next year to communicate its latest model results and reiterate how climate change commitments and economic growth go hand in hand. Many policymakers (and some scientists) believe that yet another year will not matter in the grand scheme of things, but this overlooks the fundamental tenet of climate science: emissions are cumulative.

There are many reasons why climate science has become intertwined with politics, to the extent that providing impartial scientific analysis is increasingly challenging and challenged. On a personal level, scientists are human too. Many have chosen to research climate change because they believe there is value in applying scientific rigour to an important global issue. It is not surprising then that they also hope that it is still possible to avoid dangerous anthropogenic interference with the climate system. However, as the remaining cumulative budget is consumed, so any contextual interpretation of the science demonstrates that the threshold of 2 °C is no longer viable, at least within orthodox political and economic constraints. Against this backdrop, unsubstantiated hope leaves such constraints unquestioned, while at the same time legitimizing a focus on increasingly improbable low- carbon futures and underplaying high- emission scenarios.

On a professional level, scientists are seldom trained to engage with policymaking; where opinions are encouraged and decisions informed as much by ideology as by judgement of the science, economics and so on. Policymaking is necessarily a messy process. Scientists, however, often assume that the most effective way of engaging is by presenting evidence, without daring to venture, at least explicitly, broader academic judgement. Perhaps, for narrowly defined disciplinary study, this is entirely appropriate. Yet many highly respected researchers are emerging with interdisciplinary expertise. Academic training has begun to foster the ability of researchers to embed quantitative analysis within a wider sociopolitical and economic context. Nevertheless, reluctance to proffer academic judgement confidently remains, particularly when such judgement raises fundamental questions about the viability of so-called real-world economics.

A Sharp Rise in Retractions Prompts Calls for Reform

Carl Zimmer

PLEA Dr. Ferric Fang argues that science has changed in worrying ways.
In the fall of 2010, Dr. Ferric C. Fang made an unsettling discovery. Dr. Fang, who is editor in chief of the journal Infection and Immunity, found that one of his authors had doctored several papers. 

It was a new experience for him. “Prior to that time,” he said in an interview, “Infection and Immunity had only retracted nine articles over a 40-year period.” 

The journal wound up retracting six of the papers from the author, Naoki Mori of the University of the Ryukyus in Japan. And it soon became clear that Infection and Immunity was hardly the only victim of Dr. Mori’s misconduct. Since then, other scientific journals have retracted two dozen of his papers, according to the watchdog blog Retraction Watch

“Nobody had noticed the whole thing was rotten,” said Dr. Fang, who is a professor at the University of Washington School of Medicine. 

Dr. Fang became curious how far the rot extended. To find out, he teamed up with a fellow editor at the journal, Dr. Arturo Casadevall of the Albert Einstein College of Medicine in New York. And before long they reached a troubling conclusion: not only that retractions were rising at an alarming rate, but that retractions were just a manifestation of a much more profound problem — “a symptom of a dysfunctional scientific climate,” as Dr. Fang put it. 

Dr. Casadevall, now editor in chief of the journal mBio, said he feared that science had turned into a winner-take-all game with perverse incentives that lead scientists to cut corners and, in some cases, commit acts of misconduct. 

“This is a tremendous threat,” he said.
