"What we found is that temperatures increased in the last hundred years as much as they had cooled in the last six or seven thousand," he said. "In other words, the rate of change is much greater than anything we've seen in the whole Holocene," referring to the current geologic time period, which began around 11,500 years ago.

Hey Brian... I noticed that you never did offer anything to back-up your claim that atmospheric CO2 is rising due to outgassing from the oceans AND CO2 is rising in the oceans because it's somehow coming out of the sea-floor. How exactly is that supposed to work?

Article title:
"Peer-Reviewed Survey Finds Majority Of Scientists Skeptical Of Global Warming Crisis"

ACTUAL FINAL REMARKS FROM AMS (Linked to in the article!):

There is unequivocal evidence that Earth’s lower atmosphere, ocean, and land surface are warming; sea level is rising; and snow cover, mountain glaciers, and Arctic sea ice are shrinking. The dominant cause of the warming since the 1950s is human activities. This scientific finding is based on a large and persuasive body of research. The observed warming will be irreversible for many years into the future, and even larger temperature increases will occur as greenhouse gases continue to accumulate in the atmosphere. Avoiding this future warming will require a large and rapid reduction in global greenhouse gas emissions. The ongoing warming will increase risks and stresses to human societies, economies, ecosystems, and wildlife through the 21st century and beyond, making it imperative that society respond to a changing climate. To inform decisions on adaptation and mitigation, it is critical that we improve our understanding of the global climate system and our ability to project future climate through continued and improved monitoring and research. This is especially true for smaller (seasonal and regional) scales and weather and climate extremes, and for important hydroclimatic variables such as precipitation and water availability.

Technological, economic, and policy choices in the near future will determine the extent of future impacts of climate change. Science-based decisions are seldom made in a context of absolute certainty. National and international policy discussions should include consideration of the best ways to both adapt to and mitigate climate change. Mitigation will reduce the amount of future climate change and the risk of impacts that are potentially large and dangerous. At the same time, some continued climate change is inevitable, and policy responses should include adaptation to climate change. Prudence dictates extreme care in accounting for our relationship with the only planet known to be capable of sustaining human life.

Anyone else see a disconnect? We're now looking at 400ppm in the rear-view mirror... WAKE UP!!!

That claim fails the sniff test: shore sea level markers are up minutely, and supposed "victims" like Bangladesh are gaining territory, not losing it. Real sea rise is like real warming, proceeding at a very slow pace since the end of the 19th Century or so. It will amount to a few inches by 2100, not more and not a problem. Some of the data corruption is illustrated by the use of a Hong Kong marker as a baseline, when it has been known for about a century that the site is subsiding. There is much more.

Tesluthian | 13 May, 2013

The survey looks like a good citation Brian, providing the group surveyed was completely random. For exa, you can't survey a biased group, like "Scientist Against Global Warming", and induce & extrapolate that to the general population of scientist as to the general percentage.

Here's another one. Apologies if already posted.

To me I see two things in the above link.

1) One pro group , using the Internet to create a social clique by method of private emails etc to use socialization and/or social coercion to bring everyone to their group and their view. That's why it's important to use the complete scientific method, not just parts of it.

As for the emails, they should publish the whole email and underline , rather than just use a quote, which may be out of context.

2) It's scary how the anti group can read and download private emails. Other groups like journalist have read people's computer screens to get a story etc. So they rationalize breaking the law for their personal benefit.

Personally I think global warming may be the greatest thing to ever happen to America and the world, whether it's factual or not.  It can keep a competition between transitional fossil fuels and renewables, keeping the price of both down. Eventually America can export ALL it's fossil fuels, when renewables take over, this solves the debt problem through increase revenues. Health savings are also huge, as is defense savings, no more protecting oil countries, and relief for the soldiers.

But if you want to know the real  conspiracy behind "Global Warming & Research", it was the conservatives! They initiated funding for developing global weather models which was the progenitor of the IPCC ! See link at about 38:30 mark.

It explains Margaret Thatcher and the conservatives started global warming research for a hidden agenda of other reasons. This despite the counseling of this man, Special Advisor to Margaret Thatcher, Lord Christopher Moncton, an anti-global warming speaker now. See his qualififications at link vid at 02:50.

Lord Moncton is a gifted anti-warmer who advised Thatcher.

Yet here is Thatcher at the UN promoting Global Warming, but probably with an ulterior motive and for her own political gain to defeat coal unions in Britain, etc, etc. See Thatcher UN speech link.

So you see, conservatives can say just like John Kerry that:
Actually, before they were against global warming [sic], they were for it !

Or as in another quote :
"Oh what a tangled web we weave, when first we practice to deceive".

And now your stuck with it.

Brian H | 13 May, 2013

The rock beneath the oceans is loaded with carbonates, and pools of CO2 arise. In and near some deep seeps, blobs of liquid CO2 are rising out of the seafloor (pressure effects). The stupid "mankind makes and controls CO2" meme is a bore.

Brian H | 13 May, 2013

Here's a mathematical Fourier analysis from Germany of the real climate patterns:

In summary, we trace back the temperature history of the last centuries to periodic ( and thus “natural” ) processes. This applies in particular to the temperature rise since 1880 which is officially claimed as proof of anthroprogenic global warming. The dominant period of ~250 years is presently at its maximum, as is the 65 year period ( the well-known Atlantic/Pacific decadal oscillations ).
Cooling as indicated in Fig. 2 can therefore be predicted for the near future, in complete agreement with the lacking temperature increase since 15 years. The further future temperatures can be predicted to continue to decrease, based on the knowledge of the Fourier components. Finally we note that our analysis is compatible with the analysis of Harde who reports a CO2 climate sensitivity of ~0.4 K per CO2 doubling by model calculations [3].

"rock beneath the oceans is loaded with carbonates" the question at hand is how the carbon goes from the rocks to the ocean. There is no evidence this is occuring on the scale neccessary.

If the globe is warming but we're not absolutely sure we're the cause, then so what. Do we tinker with something we don't have all the pieces to? Suppose if we're causing it, and we're prolonging the next cycle into ice age. Isn't that a good thing? If we screw around without knowing for sure what the cause is then we're screwed. What we should do is what every human and animal has done since the start of life ADAPT! Water rises; build damns, etc. Tinkering with the climate without a consistent longtime data set instead of ancient interpretations of ice cores from remote locations is arrogant presumption. Keep studying and collecting data but until we're sure ADAPT!

nwdiver93 | 14 May, 2013


If your argument is that we should stop tinkering with the climate I agree 100%... which means we should stop adding Billions of tons of a gas that EVERY paleo-climate study has shown is the DOMINANT temperature regulator on the planet. We've never had an ice age with CO2 >250ppm. With CO2 now at 400ppm and climbing we're in no danger of another ice age.

"Keep studying and collecting data but until we're sure ADAPT!"
EVERY study commissioned since the 1980s has said about the same thing. Watch "Climate Wars" on Youtube. When do we stop running from reality? Humans can adapt but at a cost. Most species can't; we're losing a lot of biodiversity thru pure ignorace. The sad thing is that it's less costly to use clean energy than to adapt to the consequenses of the fossil fuels we're addicted to.

Tesluthian | 14 May, 2013

Ok here's my unprovable , unscientific , hypothesis. In a thousand years we will all be midgets. Higher carbon will crowd out oxygen. Plants will get bigger and animals will get smaller because of less oxygen. Just like insects used to be gigantic, eons ago when there was more oxygen, now insects are tiny.

BrianH's great, great, .....great great grandchildren will be 36 " 's tall when adults, as will all other adults. This will require less oxygen per person. Say 10-15 trillion people in 3013. Gigantic SUV cars will be the size of a Cooper. Houses will be tiny, 400 square foot house will big considered big. Less meat per person required. Less strain on farm resources, energy use etc, etc.

Of course if you want to speed up the process, we can start bio-engineering now.

Could it happen ? Maybe 1 chance in a hundred, we should know in about 1000 years.

nwdiver93 | 14 May, 2013

Brian H | 14 May, 2013

You have no concept of scale. Doubling CO2, which would almost exhaust fossil fuel resources, would cut oxygen by less than 1%. Much less.

Adaptation to climate is about 1000X as cost-effective as this stupid "mitigation" nonsense being pushed.

"TRCS: Without question, one of the most spectacular scientific accomplishments of the 20th century was the Apollo landing of humans on the moon and their return. The mission required exhaustive testing of the concepts, models, and equipment against all appropriate data. If the data did not exist, it had to be compiled. Last year, some retired members of the Apollo team, and others, formed The Right Climate Stuff (TRCS) research team, volunteering to apply their skills to examine the scientific basis of the claim that human emissions of carbon dioxide (CO2) are causing dangerous global warming and/or climate change, which they term as Carbon-based Anthropogenic Global Warming (AGW).
Last week,[mid-April] TRCS team issued their findings: “Anthropogenic Global Warming Science Assessment Report.” This clearly-written 21 page assessment states that the empirical evidence of Carbon-based AGW is sorely lacking.
The major findings include:
· Carbon-based AGW is not settled.
· Natural processes dominate climate change (although many are poorly understood).
· Non-Carbon-based anthropogenic forcings are significant (land use change, urban heat island effect, black carbon, etc.)
· Carbon-based AGW impact appears to be muted.
· Empirical evidence for Carbon-based AGW does not support catastrophe.
· The threat of net harmful total global warming, if any, is not immediate and thus does not require swift corrective action.
· The US Government is over-reacting to concerns about AGW."

TRCS -- a bunch of good old boys from oil billionaire Charles Koch's Heartland organization. Chief goal is to teach bad science in schools. Second goal is to attack climate change scientists. "Teach the controversy," they say. Sound familiar? Yes, the war cry of the Intelligent Design frauds. Same approach.
Same BS. You can't trust anything they say. This is the same crowd that said commercial space enterprises like Space-X are a dangerous idea.

Brian H | 18 May, 2013

The Koch and Heartland boogey-men operate only in leftist imaginations. If you ever find any documentary evidence that amounts to more than gross exaggerations and misrepresentation, by all means show it. The actual amounts either contribute to Sceptical science is miniscule. Heartland's entire budget, mostly directed at health issues, is barely coffee break money for behemoth advocacy funders like the Tides Foundation, etc.

You reveal yourself as a little echo chamber for baseless talking points by repeating such nonsense.

The opposition to commercialization of space was/is led by such NASA loyalists as (the late) Neil Armstrong, btw. They thought/think only government micro-management -- at 10X the cost -- could/can ensure safety, despite the repeated fatal blindspot errors it has committed.

Skotty | 18 May, 2013

Global Warming and humankind's contribution to it is almost undeniable. A couple more decades of data collection and I think it will be completely undeniable. Anyone who disagrees is in denial, but they will some day have to accept the truth.

What's more pertinent and unknown is how much is too much? Maybe we are still fine for the moment, but at some unknown atmospheric CO2 level, things will go bad. Possibly very very bad. What Elon has said on the matter is dead on with my own viewpoint. Let's not play out that atmospheric experiment. With it's global implications and unknown outcomes, it's just too risky, and therefore irresponsible. We need to make changes immediately to mostly neutralize our unintentional affects on the atmosphere.

A good parallel to this was the banning of CFCs and halons due to ozone layer depletion back in the late 1980's. We never saw any dramatic effects from losing the ozone layer in our atmosphere because we took action to prevent it. Science was able to measure the changes and make a good case for why we needed to reduce or eliminate CFCs and other ozone depleting chemicals. We took action, and the ozone layer stabilized. Maybe completely destroying the ozone layer wouldn't have been that bad. Should we have just let it go to see what would happen? I sincerely hope none of you would answer yes to that.

History will judge you for your actions, or should I say, inactions, on matters like this. If you can be convinced by science that using a rear facing child seat reduces the risks to your children, it shouldn't be that great a leap to be convinced to reduce the risks to all the world's children by reducing our unintentional affects on the atmosphere.

Brian H | 18 May, 2013

Your example of successful intervention is a joke. The ozone cycle CFC reduction should have taken about 20 yrs to have any effect. But ozone levels rose almost immediately. It has subsequently been determined this was due to utterly unrelated natural drivers.

The data, in fact, strongly discount CO2 effects. It continues to accumulate at higher rates than the most extreme projections, but temperatures have been far below even the drastic emission-reduction projections for almost 2 decades. Total Fail. An unbiased observer could conclude that CO2 actually causes cooling (negative sensitivity). Which (with feedbacks given their proper signs) is quite possible.

The AGW speculation is a dead letter.

nwdiver93 | 19 May, 2013

"An unbiased observer could conclude that CO2 actually causes cooling"

Seriously Brian... now you're denying physical laws? Scientific studies can be kind of "wordy" perhaps this is more your speed...

Still waiting on a source explaining how the increase in atmospheric CO2 is coming from the seafloor... which would raise another question; if the rise is coming from the seafloor then where is the ~27 Trillion lbs that we pump into the atmosphere annually going? Wouldn't that be a much simpler explanation?

Brian H | 19 May, 2013

The behavior of CO2 in those "basic physics" studies comes with a caveat: excluding all convective and conductive heat transfers. But those are overwhelmingly dominant in a real atmosphere. The science of real-world observations is unanimous: the models' extrapolations using the radiative formulae are wrong on all counts. Feedback is so massively negative that it renders the CO2 effect undetectable at anything less than combustion chamber temperatures.

Local news


Biologists removed three more dead bottlenose dolphins in the Indian River Lagoon Monday, bringing this year's total lagoon bottlenose body count to at least 30.

The National Oceanic and Atmosphereic Administration already has declared that 100 or so manatee deaths in the lagoon since mid 2012 an Marine Mammal Unusual Mortality Event

As many as 300 brown pelicans have also died in the lagoon region

Researchers find levels of mercury. They also find high incidence of tumors, heart problems, cancer, stomach ulcers, skin lesions, genital herpes and other emerging ailments previously thought rare in dolphins.

Researchers have pointed to water tainted by treated sewage and runoff as the possible cause.

On a different note, this is not from the local news, but one small housing area chopped down all 137 beautiful oak trees . They did not like the leaves falling in their swimming pools.

I know so many are worried sick about Global Warming, but could you not join in trying to solve some of our more immediate concerns?

"convective and conductive heat transfers"

How exactly do these help transfer heat into a vacuum? Last I check the earth is surrounded by a vacuum. There is only one way energy leaves a planet and that's through radiation. Your ignorance of basic facts never ceases to amaze.

To save you another spurious post the top layer of the atmosphere is actually cooling... thanks to... you guessed it, our "friend" Carbon Dioxide. Exactly what you would expect as more energy is blocked near the surface. No sources again Brian?... come on

Amen to that!

The death of the EV1 and the fabricated bankruptcy of the auto industry, which was issued in order to restructure it, were one of the greatest crimes against humanity since WW2. Even more so as they have been doing everything half assed after people have lost so much.

There is nothing more important than our atmosphere and our water.

EV1 was the William Wallace of the auto industry, it was shredded then spread across a nation and slowly has reverberated around the world. Tesla is the Robert The Bruce in this story and they have tons of warriors behind them now!

We lost the EV1, 10 years of cleaner air, and will most likely absorb another crash as a result of all this,but we will WIN and thankfully we got Tesla because of it! If not I'd be more concerned about the future than I already am.


Brian H | 19 May, 2013

That's classic subject changing. If you want a direct test, all models predict lower IR exiting the Earth as CO2 "traps" it as the surface warms, but satellites measure increased OLR when and where temperature rises (outgoing Longwave Radiation) as per normal non-trapping expectation. The Earth dumps its "excess" heat without breaking a sweat. There is no AGW.

Brian H | 24 May, 2013

Judith Curry has a marvelous post, citing Greg Melleuish on the dangerous (to all concerned) seductiveness of academic abstraction-addiction. “‘Model’ academics tend to be driven to abstraction”

Why has climate change proved to be so popular among academia as a group? I think that there are a number of answers.
The first is naked self-interest. They have discovered that with climate change they are on a real winner. They can claim that the government needs to fund them so that they can find ways of overcoming the effects of climate change, even reverse it. The more that is done on climate change, the more that needs to be done. As a research topic it appears to be one that can be milked forever.
The second is that as a topic it is an expression of the academic desire to reduce the world to a series of models that can be manipulated to predict the future. We live in a world that is both complex and contingent. It is a delusion to believe that we can create a model that depicts reality in such a way that we can control the future. When we attempt to do so we simply remain in the abstract world of the model and become its slave.
The third is a form of moral panic that seems to have overcome many academics. A major discovery of the past 100 years is that education and devotion to intellectual matters does not make modern human beings more rational. Academics, like other people, are prone to scares and panics, and hence to using their intellects in defence of irrational projects.
Academics, like many other intellectuals, have a very high opinion of themselves and their rightness. Humility is not a virtue in their world. If you are right and you have good intentions, then surely you should not only be heard but should also prevail. In fact, you probably believe that you have a duty to prevail and to drown out the views of those who lack your qualifications and capacity to employ models. They are just inferiors who need to be brought into line.

Why be critical of the government when it is the government that hands out research funding, jobs and other goodies? Academics know on which side their bread is buttered. After all, bureaucrats are also addicted to abstract models of the society they are employed to administer. It is a marriage made in heaven.

1) CO2 is a "greenhouse gas" in that it absorbs infrared light far better than visible light.

2) CO2 is now >390ppm up from ~280ppm 200 years ago most of that increase in the last 100 years

3) Humans now add ~30 Billion tons of CO2 annually; More than enough to cause the increase in CO2 that has been seen.

Simple observations... How can AGW be false?

Brian H | 24 May, 2013

Because it's trivial in the real atmosphere. H2O is scores of times more potent and strongly represented in the atmosphere, and has many of states and behaviors that CO2 lacks, from evaporation to heat absorption. It is very unevenly distributed, and reacts both powerfully and subtly to changes in insolation, thermal flux (conduction) and more.

Consider the driest landmass areas. Little water in the air, just CO2 to hold the heat in at night by "infrared absorption and emission". But the "blanket" is missing: the ground and air both cool fast at night, down to the dew point, where water takes over. CO2, at atmospheric temperatures (as opposed to combustion chamber temperatures) has negligible radiative effect.

All the models require a tropical heat buildup (from CO2) to spread to higher latitudes. It has never been found; the opposite is observed: high latitudes warm first. FAIL.

nwdiver93 | 25 May, 2013

You appear to have the same confusion as the Mexican study you referenced above...

CO2 has negligible radiative effect WHEN WATER VAPOR IS PRESENT. It's not always present, when it's dry CO2 has the radiative effect of ~1.5w/m^2.

The Fact that water vapor has a preference for the same wavelengths as CO2 is part of the AGW theory... you really do think like a creationist... cherry-picking the bits that fit your narrative and ignoring the rest.

The belief that CO2 can't block infrared light is first rate ignorance... YOU CAN OBSERVE IT DIRECTLY!!!

Brian H | 25 May, 2013

That is a collection of non sequiturs and straw-man arguments. All the IPCC/NASA etc. publications acknowledge that feedbacks are poorly understood, then proceed to "plug" with assumptions and parameters, about 20 in the case of most models. By the time you're up to 4 or 5 you're consigned to speculative "what if" scenarios.

You're trying to argue against positions not taken by sceptics. There is no conservation of either infrared or radiation in general, only thermal energy and entropy in total, as a whole, and the interlocked system of such transfers renders the effects of CO2 trivial, or moot. The baseline on which the speculation rests in the real world reduces to about the 1970-2000 period, and the majority of that change occurred in a single year, 1997 (a Super El Nino year). Correlation with CO2 variance is negligible when venturing outside that time slice.

Skotty | 25 May, 2013

Follow the money often becomes the argument of both sides. When such arguments have academia on one side, I would argue the argument is in academia's favor on the matter.

My wife has a PhD and I've spent some time around academia. I have yet to ever meet one who's primary motivation is monetary gain. They care far more about their work than the money it generates.

When it comes to climate change, for scientists and academia money is a minor forcing. For the climate change deniers, money is arguably a major forcing. The whole reason there is such a big debate is because, in this particular instance, science found a problem that will cost industry money instead of making it more.

I could draw another parallel to Elon here. I've seen a lot of comments on the net about how Elon is just after money. But anyone who knows him better knows that he cares more about the mission than the money. The great thing about Elon, however, is that, unlike many business visionaries, he still knows he needs to do what has to be done to be profitable and stay in business. Academia has to submit proposals to compete for grants for money, and the good ones stay in business, so to speak, but it's always secondary to the mission.

It's such a shame that some here feel that they must resort to ad hominem attacks and conspiracy, even if they are on the correct side of the argument.

Regarding question number three on the aforementioned quiz, solar variability cannot be the cause of global warming since 1950. The only applicable cause on this scale of time could be "cycles of solar variability"; the other causes are on scales of time of thousands of years.

Unfortunately for the authors of the quiz, solar variability has not correlated with the trend of global warming since 1950. Solar forcing has fluctuated, but has remained, on a scale of time of a decade, relatively constant, according to NASA. If you look at the graph and find that solar irradiance has not been constant on the specified time scale, then please reread the previous sentence very carefully.

Brian H | 25 May, 2013

This is all baby talk, far behind actual research.

Climate science projections depend on positive water and cloud feedback tripling any CO2 effects. All evidence to date shows net negative feedback, tending to stabilize the system, rather than promote catastrophic positive feedback runaway. No system based on positive feedback would have endured even minor to moderate perturbations.

As for "for scientists and academia money is a minor forcing. For the climate change deniers, money is arguably a major forcing," the opposite is true. Try to find documentary evidence of ANY industry or government funding of scepticism. Academics and scientists, by contrast, spend much of their time chasing grants and funding, with Climate Science being a kind of gift from the $$ gods for them. Their research papers often paste on laughable declarations of loyalty to the Cause, even if the results are directly contrary. Then comes the universal begging line: "More research is needed." "by me!" is the unspoken real meaning.

There is very little CO2 in the atmosphere. Most of the greenhouse gas is
water vapor. Greenhouse gases are necessary to even out the temperature.
If you are in a dry area the temperature changes a great deal.
I live near the ocean and the temperature ranges between
40 and 70 during the year. It very seldom freezes here. Also,
I wear a flannel shirt all year long.

The atmosphere is composed of the following:

•Nitrogen (N2) 78.084%
•Oxygen (O2) 20.946%
•Argon (Ar) 0.934%
•Carbon dioxide (CO2) 0.0383 %
•Neon (Ne) 0.001818 %
•Helium (He) 0.000524 %
•Methane (CH4) 0.0001745 %
•Krypton (Kr) 0.000114%
•Hydrogen (H2) 0.000055 %
•There is also a varying amount of water vapor, depending on the altitude and conditions where it is measured.

Also, it appears the CO2 levels rise after the temperature rises.

-CO2 rises after temperature rises... YES; This is the NATURAL way CO2 fluctuates.

-Then CO2 is a symptom of warming and does not cause warming... NO; The natural warming is triggered by Milankovitch cycles. Many have tried and ALL have failed to show that the Milankovitch cycles are responsible for the MAGNITUDE of natural warming we see between ice ages. The changes in Earths Orbit are too small. Only taking CO2 forcing into account can the MAGNITUDE be explained. Slight warming releases CO2 resulting in further warming until equilibrium is achieved at a higher average temperature.

-CO2 rise in the past was natural... it's natural now. NO; FACT: Humans are adding 30 Billion tons of CO2 annually. FACT: 30 Billion tons is ~5ppmm of Earths atmosphere. FACT: CO2 is rising @2ppm / year.

All comes down to 3 SIMPLE FACTs that have been challenged in the last 9 pages twice.

- (CO2 forcing is irrelevant because water vapor is everywhere)... NO... ever heard of "Rain"? Water comes and goes leaving CO2 to do its thing.

- (CO2 Rise is coming from the seafloor)... what? Does this make sense to anyone?

1) CO2 is a "greenhouse gas" in that it absorbs infrared light far better than visible light.

2) CO2 is now >390ppm up from ~280ppm 200 years ago most of that increase in the last 100 years

3) Humans now add ~30 Billion tons of CO2 annually; More than enough to cause the increase in CO2 that has been seen.

If these three are TRUE explain how AGW is FALSE... CITE YOUR SOURCE.

The quiz is amusing... It's like a gunman saying he was innocent because it was the bullet that did the killing. Without CO2 there is no significant climate change. A rise in CO2 can be caused by a slight increase in temperature due to changes in earths orbit... or Billions of bald primates burning carbon-based fuels. CO2 is CO2 wether it's coming from a tail-pipe or the oceans.

Yes, Water Vapor is the most dominant greenhouse gas... So to return the the gunman analogy water vapor is the gunpowder but CO2 is the primer. The trigger can be pulled by a variety of things; massive vulcanism (100s of times what we have now), Orbital shifts or burning fossil fuels.

The Discovery Institute? I really am debating creationists...

At least Elon is taking things more seriously...

Ad hom to the end. Truly the lowest form of thought and argument.
