Althouse: "Ferocious storms and deadly heat waves are occurring with alarming frequency all over the world."

July 13, 2011

"Ferocious storms and deadly heat waves are occurring with alarming frequency all over the world."

"We are living with the reality of the climate crisis every day. The only question is, how soon can we act?"

Al Gore is threatening us with reality... TV...." a live-streamed event called 24 Hours of Reality...."

I love the way reality is so propaganda-y when it emanates from The Mind of Gore.

"On September 14th, the world will join hands to create 24 hours of reality..."

That was so weird. It didn't have the slightest feeling of science to it at all.

"When you include observations of weather over the whole earth, you get some pretty amazing numbers. Here are a couple-

Number of thunderstorms occurring at any given time: 2000
Number of lightning strikes over the earth per second: 100

Expanding the lightning numbers... 100 per second equals 6000 strikes per minute, 6000 per minute equals 360,000 per hour, 360,000 per hour equals 8,640,000 per day.

Instead I would turn to this new group of scientist who want to keep the facts clear according to Oppenheimer: “I think it is important for scientists to assure that the public and policy makers have a clear view of what scientific findings are and what the implications of those findings are,” said Princeton University scientist Michael Oppenheimer. “To the extent that some members of the new majority in the House have exhibited a contrarianism to science, I think it is a good way to have a scientific community there to help keep its facts clear.”; 7/13/11, 9:45 AM

rhhardin said...: Will there be a discussion of how the actual Navier-Stokes equations were solved by the models?

Will there be a discussion of how a cycle is distinguished from a trend with an amount of data short compared to the cycle?

The discussion I've seen of the former is that they don't solve the Navier Stokes equations but rather whatever they can pull out of their asses; there is no discussion at all of the latter.

You'd have to overcome an explosion of eigenvalues, which doesn't seem likely. It's sort of in the math.; 7/13/11, 9:51 AM

This SOUNDS like a scientific criticism, but tis't he same thing as saying "if we can't predict weather we can't predict climate".

If the Navier-Stokes equation that govern climate couldn't be approximated, then there would be no such thing as "climate". The waether would never settle down enough to be considered "climate".

But because over long times and large distances the instabilities work themselves out, there IS such a thing as climate and it CAN be modeled.; 7/13/11, 9:56 AM

traditionalguy said...: It is a delusion crafted to make a sci-fi story into our public policy for profit.

The weather acts weird when cool air merges with warm air.

Cooling causes weird weather more than warming.

The past 3 winters have been much colder.

Since 1920s the hot days have been hotter, the arctic has frequently melted in summers and refrozen, and floods and droughts have been in greater size and intensity.

Co2 is a beneficial trace gas that has no effect except as fertilizer to help plants grow.

Gabriel Hanna said...: In a way this is much like the debate on public policy on tobacco.

As a libertarian I think it is wrong for the government to ban smoking in privately-owned businesses, and I think it was wrong for the states to rape the tobacco companies in the 90s.

But, in arguing against those policies, how seriously could I be taken if I argued that smoking doesn't cause any health problems and all the science showing it does is faked by commmunists to further their leftists agenda? (I am loosely paraphrasing shouting thomas--check his comment before you accuse me of erecting a straw man).

It's complex because of feedback, not because of countless variables. There are countless variables in the moleclues of air, yet you can predict with certainty how to blow up a balloon, can't you?

You don't know what's going to happen and neither does anyone else.

More FUD. "If we don;t know everything it's the same as knowing nothing"--that's your argument.

There are countless variables in how people drive--personalities, their equipment, their habits and schecules--and yet you understand the traffic patterns in your hometown pretty well.

Gabe, I normally have a very healthy respect for your comments hereabouts, but you seem to have left your A-game somewhere. There are a finite number of feedbacks and variables in climate, but I seriously doubt our current capability to a) collect the data cleanly and b) successfully build the models. We're talking macro here.

Blowing up a balloon involves a very small set of variables that are easily controlled and anticipated. Otherwise most clowns would be out of a job. ManBearPig, on the other hand, has found a way to make clowning profitable (emphasis on profitable) without balloon animals.; 7/13/11, 10:34 AM

Thanks for proving my point. You must not actually commute right? Traffic patterns are NEVER exactly the same, and some days are significantly different than others. And they can't be predicted!; 7/13/11, 10:38 AM
Gabriel Hanna said...: @MarkG:Traffic patterns are NEVER exactly the same, and some days are significantly different than others. And they can't be predicted!

So, you never avoid certain routes or intersections at certain times of day when you are in a hurry, right? And "rush hour" doesn't exist?

I never claimed they could be predicted EXACTLY, down to the minute and the license plates of the cars and where they will be found at what second. But the trends are obvious, and every human being who drives knows this, and there's no point in being disingenuous about it.; 7/13/11, 10:43 AM
SteveR said...: What do we really know?

Al Gore's understanding of climate science starts with his belief that man has a negative impact on the environment. The problem is that while the latter is undoubtably true, its far from certain what that has to do with climate. What is certain is that he has made a lot of money and created a massive carbon footprint.

But the laws and the lawsuits WERE based on health-related arguments--that it's unsafe for people to be exposed to smoke at work, and that smokers' health problems are driving up the cost of medical care and so the tobacco companies need to pay for that.

There are a finite number of feedbacks and variables in climate, but I seriously doubt our current capability to a) collect the data cleanly and b) successfully build the models.

On what is your doubt based? What level of accuracy do you demand and why isn't the current accuracy good enough?

Is it too much to ask that you read what I linked to? Isn't this argument too important to rely on sound bites or comments on a blog?

Blowing up a balloon involves a very small set of variables that are easily controlled and anticipated.

6.0 * 10^23 moleecule, give or take, of varying masses and speeds which are not known exactly. How can such a complicated system boil down, as you claim, to "a few variables". (These variables of course are P, V, n, and T.)

exhelodrvr1 said...: Yes, Gabriel, it can be modeled. But none of the models designed so far come anywhere close to incorporating all the data that is available, a significant portion of the data that is available is corrupt for one reason or another, and there isn't enough data from a long enough period to be able to come anywhere close to figuring out what inputs cause what effect on the weather/climate.; 7/13/11, 10:56 AM

Joe said...: The single biggest problem with climate science is that we know the base data is almost complete bullshit. Temperature data is not only inconsistant historically, but much of the original data has been lost--what we mostly see is the "adjusted" data, but we aren't told what the adjustements were. Then there is the proxy data which turns out out to be extremely innacurate. Oddly some of the concrete data we do have, such as actual measurements of atmospheric CO2 back to the early 19th century, is ignored (since it doesn't support the hysterical hypothesis.)

All that aside, what gets me the most is the shear hubris of the Al Gores in the world that they know the solution. Nature has repeatedly shown that man cannot control it.; 7/13/11, 10:59 AM

We don't know where every grain of dust and piece of gravel in the solar system is, yet we can predict eclipses accurately to the second for hundreds of years in the future. How can they do that when they don't have all the data?

How much more accurate would predictions be if they used 90% of the avlaibale data, or 99%, or 99.9%--and would the extra effort be worth the accuracy?

How do we know we are in a recession if we don't know the status of every human being's employment, bank account, investments, and income to the penny?

roesch-voltaire said...: For an non-scientist commie's take on the issue, I would recommend a paper by a lawyer Jason Scott Johnston, who cross examines the IPCC's claims with peer-reviewed articles that call into question several assumptions of the narrative. But even he admits there is a warming trend, but the question is can we measure all the feedbacks in the system and he writes" ... with the debate coming down to conflicting
views about the reliability of alternative datasets on solar activity. Perhaps even more
importantly, a growing body of sophisticated theoretical work confirms that the nonlinear
global climate is subject to inherent warm and cool cycles of about 20 to 30 years
in duration, with substantial evidence that a warm cycle was likely to have begun in
1976. As for the latitudinal pattern of twentieth century warming, with more pronounced
warming in the Arctic in particular, there is now substantial evidence establishing that at
least one half of such warming was due to the deposition of industrial era soot on the
snows and ice of that region.-- and where does the soot come from?; 7/13/11, 11:04 AM

1) The existing data, at least as entered into the models, has been shown to be inaccurate.

2) The models don't utilize all existing data.

3) There is a great deal of related variables that aren't incorporated into the models at this point.

4) The existing models have shown themselves to be extremely poor in making predictions.

Right now those of you trying to predict the future climates, and trying to determine what controllable variables will have the greatest impact on the future climates, and what steps can be taken by mankind to adjust those variables, are stuck in a loop of steps 1, 2, and 3 above. They may not be arranged in that particular order. But until all three of those are changed appropriately, 4) is a guaranteed result.; 7/13/11, 11:17 AM

Any fool knows that clouds stop sunlight like an umbrella.

Increase the clouds 2% and the sun's affect is cooled.

The solar flares (sunspots) shield the earth from the cosmic rays that form the clouds.

So when sunspots go dormant, the cloud formation increases and causes the cooling that we have been experiencing since 2008.

The past year the 32 years of warming and 14 years of no increases netting .7 of a degree C increase was reversed in one year with a .7 of a degree C cooling.

Anonymous said...: Anybody who compares the complexity of sending a spacecraft to Mars at one particular instant in time (where we know the current and, for all practical purposes, future positions of all the planets, the sun, the pertinent asteroids, etc.) with the future of the climate decades from now has no fundamental understanding of physics. The laws of orbital motion of large bodies are not chaotic. The law of gravity is not chaotic. The concept of the conservation of energy and momentum is not chaotic. Even the slight shifts rendered by the laws of relativity are well-understood and factored into any mission when determining an orbit (if they were chaotic, we wouldn't be able to accurately predict and compensate for their very tiny effects).

Compared to that, climate science is a joke. You don't get to Mars based on statistics and proxies (hmmm, where is Mars likely to be in 2 months?), you get there with hard science and equations. Climate science, by comparison, is a shot-in-the-dark guess based on incomplete and frequently inaccurate statistical information fed into models that are infintely more complex and fallible than any orbital calculation. Seriously, if planetary science were anything like climate science we would never have left the planet (and there'd be no weather satellites, GPS, moon landings, Voyager probes or anything else outside our atmosphere).; 7/13/11, 11:25 AM

That is completely untrue in calculating a transit to Mars. We might not know the position of every grain of sand or dust, but we also know it DOESN'T MATTER. When calculating a large spacecraft's path it is irrelevant. We can prove that with equations and we can prove that with experience. You can't do the same with climate science.; 7/13/11, 11:43 AM

This is why the word "denialist" gets used. While it may be unfailry used to denigrate anyone who is skeptical, in YOUR case it is appropriate--you are denying that something exists, which it unambiguously does.

Joe said...: RE: GISS data.

Nobody is even sure what the data set is. Evidence is that the raw data was adjusted immediately and both the raw data and what methods were used for that adjustment were lost. Even Phil Jones has stated that GISS data was corrupt.

Ironically, Jones has also admitted losing the original raw data which they used. (Not only that, they have no documentation of how the raw data was adjusted.)

The bottom line is that for all the published data sets from the mid to late twentieth century, we do not know the provenance. There is a very serious question as to whether we have any accurate raw data for that time period. I believe the overwhelming evidence is that we do not.

(We KNOW that the HO-83 Hygro-Thermometers introduced in the 80s had a serious [non-linear] flaw that could lead to measurments being off by up to 3 degrees! The error isn't linear nor consistant except that the maximum temperatures were off by a much higher amount than the minimum temperatures. Once this was learned, how much raw data was simply adjusted immediately, how much was adjusted later and how much left alone. We don't know.

That aside, that the method of measuring the temperature at a given site was changed puts even "accurate" measurements into question. Add to that that the stations themselves were often moved and/or things such as pavement added next to them gives them a margin of error in excess of the claimed warming (or cooling.)

Data from the 19th century will show an increase of temperature since the norther hemisphere was emerging from the mini-ice-age and the Tambora event.); 7/13/11, 11:51 AM

Ignorance is Bliss said...: Here is the test I'd like to see a climate model pass before I'd make any significant steps to society:

1) The climate model can take into account any scientific formulas, laws and constants that the modelers think are relevant. It may also use any climate data recorded before the year 2000 for calculating statistical relationships used in the model. They can also include unusual events, such as volcanic eruptions, that are not caused by climate but can effect it.
2) The modelers may run their simulations up until the year 2000, tweaking variables as they see fit to get the best model they are capable of producing.
3) Once they believe they have the model correct, they announce a public demonstration. The demonstration consists of two parts. First, they model the climate from 2000 to the present, to see how well their model tracks reality. Once they start this demonstration, they may not tweak any variable to get the results to match reality. I'm not sure how close the results have to be to the actual measured temperature to pass the test, this would have to be decided before the test starts. The second part of the test is to model from the year 1900 to 2100, assuming CO2 levels remaining constant at their 1900 levels. In this case, the test is to make sure that the model does not predict run-away warming or cooling over the long term*.
If the model passes this test then I'd be happy to listen to their predictions for the next 100 years. If not, the modelers need to go away and leave the rest of us alone for at least a decade. Leaving the rest of us alone include no government funding.

*Note regarding the second test: it is possible that we are at a point where the climate really would have long-term heating or cooling with constant CO2 levels. We've gone into and out of ice ages before. Thus failing this test does not prove that the model is wrong. It does, however, prove that CO2 is not what we should be worrying about.; 7/13/11, 12:05 PM

Gabriel Hanna said...: @ignorance is Bliss:

They already did those things you demand of them now: Hansen's predictions were published almost thirty years ago and they match today's climate pretty well. they already jumpred through your hoops years ago, but it's never good enough--and of course no "skeptics" do any modelling, and they do not make ANY predictions--yet you invariably prefer them, it seems.

http://www.realclimate.org/index.php/archives/2007/05/hansens-1988-projections/

In the original 1988 paper, three different scenarios were used A, B, and C. They consisted of hypothesised future concentrations of the main greenhouse gases – CO2, CH4, CFCs etc. together with a few scattered volcanic eruptions. The details varied for each scenario, but the net effect of all the changes was that Scenario A assumed exponential growth in forcings, Scenario B was roughly a linear increase in forcings, and Scenario C was similar to B, but had close to constant forcings from 2000 onwards. Scenario B and C had an ‘El Chichon’ sized volcanic eruption in 1995. Essentially, a high, middle and low estimate were chosen to bracket the set of possibilities. Hansen specifically stated that he thought the middle scenario (B) the “most plausible”.

These experiments were started from a control run with 1959 conditions and used observed greenhouse gas forcings up until 1984, and projections subsequently (NB. Scenario A had a slightly larger ‘observed’ forcing change to account for a small uncertainty in the minor CFCs). It should also be noted that these experiments were single realisations...

Scenario B is pretty close and certainly well within the error estimates of the real world changes. And if you factor in the 5 to 10% overestimate of the forcings in a simple way, Scenario B would be right in the middle of the observed trends. It is certainly close enough to provide confidence that the model is capable of matching the global mean temperature rise!

But can we say that this proves the model is correct? Not quite. Look at the difference between Scenario B and C. Despite the large difference in forcings in the later years, the long term trend over that same period is similar. The implication is that over a short period, the weather noise can mask significant differences in the forced component. This version of the model had a climate sensitivity was around 4 deg C for a doubling of CO2. This is a little higher than what would be our best guess (~3 deg C) based on observations, but is within the standard range (2 to 4.5 deg C). Is this 20 year trend sufficient to determine whether the model sensitivity was too high? No. Given the noise level, a trend 75% as large, would still be within the error bars of the observation (i.e. 0.18+/-0.05), assuming the transient trend would scale linearly. Maybe with another 10 years of data, this distinction will be possible. However, a model with a very low sensitivity, say 1 deg C, would have fallen well below the observed trends.

Hansen stated that this comparison was not sufficient for a ‘precise assessment’ of the model simulations and he is of course correct. However, that does not imply that no assessment can be made, or that stated errors in the projections (themselves erroneous) of 100 to 400% can’t be challenged. My assessment is that the model results were as consistent with the real world over this period as could possibly be expected and are therefore a useful demonstration of the model’s consistency with the real world. Thus when asked whether any climate model forecasts ahead of time have proven accurate, this comes as close as you get.; 7/13/11, 12:11 PM

How indeed? And how do you know the data they do incorporate is enough to be predictive? Every model built so far has not exhibited reliable predictive power in the short term, nor have they demonstrated the ability to reproduce historical climate. When run backwards they all create weird ahistorical scenarios, such as the desertification of Ireland.

Yes, Newtonian mechanics can produce chaotic systems, but our solar system (the Sun and eight or nine planets) is sufficiently stable that for hundreds of years analog computers have been able calculate the relative positions of the major planets an their larger moons with enough accuracy to predict conjunctions, oppositions, eclipses, etc. However, if our solitary primary star had been a binary, or had our system contained a super-giant planet in a tight orbit (such as the case in many known extra-solar systems) then simple computers like the orrery would have been impossible. The atmosphere is however so much more complex that its a wholly different kettle of fish, so to speak, even today our best peta-flop computers can't even approach the problem.

I'm truly surprised that you would invoke the mechanics of spaceflight as argument in support of these dubious models the AGW hacks have foisted on a credulous public. The orbits of Mars and Earth are well understood, seeing as their relative positions have been monitored for thousands of years and their masses and accelerations have been measured with increasing accuracy for hundreds of years, even today the relevant data are sufficiently vague that a purely ballistic flight path between Earth and Mars is unlikely to be successful. Orbital and landing missions to Mars are possible because the spacecraft are controllable and can be made to correct their courses en route. If NASA had to plan flights to Mars based on short-term observations of the kind AGW theory relies on then their missions would have about as likely to succeed as I am likely to win a trifecta on horses I picked based on their color.; 7/13/11, 12:27 PM
Andrea said...: "But maybe some people in Miami would like to know whether they should start thinking about building a seawall along their city's shoreline, or maybe some buisnessmen might be interested in the possible profits from developing cheaper methods for desalinization of seawater."

Uh, look, I grew up in Miami, and I can tell you that that city has lived with the worry of being next to the ocean for its entire history, and have long undertaken projects to stave off the inevitable beach erosion that naturally occurs because that area is a fricking sand dune. The ocean washes sand away. It is natural. It occurs no matter the climate. It will happen. It has nothing to do with how many light bulbs people turn on. It has nothing to do with a factory that ran in Victorian England. All these examples of these cities built on the ocean shore that are supposedly in danger because of global warming are already in a precarious position because they are on the ocean shore.

If you would like to know what I believe, it's this: any warming "trend" is natural because for the past several thousand years we have been coming out of the last previous big ice age. Human industrial activity, which has only been around for the past 150 years or so, has very little to do with anything beyond pollution of the immediate surrounding area, and a lot of that has been cleaned up in Europe and North America. (For bad pollution, go to Asia and Africa. Oh, but we can't saddle developing nations with any sort of restrictive sanctions because that would be wrong so let's pretend they don't exist.) Anyway, I don't see that there has been any serious sudden spike in heat and bad weather. I'm sure Al Gore does, because he's a hothouse flower who was raised in a hotel and lives in a bubble built of money. When it rains he probably freaks out.

This is getting too long. I'll just end it by saying we have more important things to worry about than whether or not someone in Miami might lose a foot of their beachfront property to rising seas.

To restate the point you ignored, there are two distinct issues that relate to climate change: (1) What is the best forecast, and what are its error bounds? (2) What is the most sensible response to that forecast? The fact that you (and I, and Gabriel Hanna) don't think that reverting to subsistence agriculture is a good idea has everything to do with (2) and very little to do with (1).

As for rich Miamians, I'm perfectly happy to let them pay for their own seawall. And I don't have to retreat to a position of "who can know?" in order to arrive at that policy conclusion.

It isn't, but I wasn't given thirty years to develop detailed models of population growth, economic trends, and traffic simulations. If I were, I could do a lot better at predicting the I-95 traffic at 6pm in 25 years.

Which is the whole point. You have people who have spent their entire careers working on the climate models and climate data, and people who know almost nothing about it feel free, for some reason, to say it's obvious they're doing it all wrong.

It's within the margin of error of the estimate of the trend. We'd still be having this argument if it were 0.02 C or 0.002 C--i kinow that because that is the magnitude of the "urban heat island" which supposedly makes all the calculations worthless.

+/- 0.2 C is far better than the nothing that the skeptics have put out.

No, it's the "We know a lot about this and much less about that argument."

We have sent satellites and probes all around the solar system and hit our targets with incredible precision. That's due to our fundamental understanding of the physics of large bodies in motion and the physics of gravity. We understand it so well partly because it's relatively simple. In the simplest system, there are only two bodies interacting. The results of our space program speak for themselves and prove the breadth and depth of our knowledge.

Compare that with climate science. It's way more complex. A two-body climate sysetm would be meaningless, unlike a two-body gravity problem. Climate science can't make precise predictions. It has no track record of making any such predictions and proving them to be true. Where is the climate science equivalent of putting a satellite in orbit around Saturn? It simply doesn't exist because climate science can't do it. It's partly in the nature of the problem and partly that climate science is in its infancy.

I'll turn your statement around and say that you make a grievous mistake in assuming that because we know something, we know enough. That argument is adapted from hubris, and it's rampant in science. By the way, I was trained in science and have no relgious affiliation but it still pains me to see scientists who can't accept the fact that when we don't know something we don't know it. They seem to think that the best knowledge in a particular topic is, by definition, adequate knowledge. It is not. That we have the knowledge to put a spacecraft in orbit around Saturn says nothing about our capacity to understand the climate 50 years from now. In one field we know a lot, in the other field we know much less. It's stupid to pretend that's not so.; 7/13/11, 1:02 PM

That's nice that you've posted a graph comparing Hansen's projections to actual temperatures, problem is it stops at 98 or 99 rather conveniently.

Here's on that goes to 2008 using NASA GISS data:

The temperature data most closely tracks scenario C, which is supposed to be a scenario covering REDUCTIONS in the growth of CO2, which obviously isn't the case.

And of course, all this is taken from the work of climate scientists--skeptics measure no temperatures and write no models. They are parasitic on the actual scientists.

The AGW hacks may be correct that the global climate will be warmer over the next century, but that doesn't prove or even support the theory. The discovered records of paleoclimate show little evidence of even decades-long stability. Ice core data from Greenland, Siberia and Antarctica show sharp temperature oscillations over the last 50K years with few plateaus lasting as long as a human lifetime. It's perfectly normal for a person to die at 75 or 80 in a climate significantly cooler or warmer than the climate into which he was born. Personally I hope Al Gore is correct when he claims the late 21st century will be warmer than the current climate. Given what can be inferred from the recent past our likely choice is between a return to an ice age (mini or major) and a poorer world, or a climate optimum similar to the early medieval world.

Wrong. Check the third figure under the James Hansen heading. The observed trends for CO2 follow scenario B while the observed trends for temperature follow scenario C. In other words the observed data disagrees strongly with his model only 20 years out.

Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you’re being had.

Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.

I have the standard that one's claims aren't proven until they're proven. The planetary physicists have proven theirs over and over. Sure, they got off to a bad start with geocentrism and epicycles but through a long, hard slog that took hundreds of years they have earned full trust since then. The climate scientists have not. One ten year blip that kinda sorta falls within one man's prediction is not exactly a towering level of proof for a phenomenon that unrolls over decades, centuries and millennia. And that's my point. The time frame for all this is way too short for any of this to be proven true. There are indications here and there (some contradictory) but that's all they are at this point. It's hubris to pretend it's more than that. It's hubris to pretend that we know more than we know. In 50 years, all this might be proven true (or at least some substantial part of it), but today, no such proof is possible. You can't prove a 50 year prediction in 10 years.

Big Mike said...: @Gabriel, I am both a mathematician and a person who does not respect AGW, or anyone who believes in it. Ten or a dozen years ago AGW made a number of testable predictions, including that global temperatures would rise essentially monotonically as CO2 rises, and that we would detect "hot spots" in the atmosphere (among a number of other testable predictions).

None of these predictions have been observed -- global temperatures have been essentially flat for the past decade, and no one has found the predicted "hot spots." The more wild-eyed predictions have been even more strongly debunked -- for instance it was predicted that children in the UK would forget what snow looks like. Last winter the British Isles had periods when nearly every square inch was covered, except for parts of Cornwall. The winter before, the entirety of the British Isles was buried in snow.

So good ol' Al Gore goes on TV and says that all the snow is a direct consequence of global warming. Ah! But snow has a high albedo effect -- it reflects sunlight back into space, thereby cooling the portion of the globe it coveres.

So did AGW overlook feedback cycles that would provide cooling effects to counterbalance warming effects? It appears that way, doesn't it?

Now we're told that the reason why CO2 levels have been rising, thanks mostly to Chinese coal-fired power plants, is that those plants also pollute the air with sulfur dioxide. So the solution for the US, if one believes the latest amendment to AGW, is not to shut down our own coal-fired power plants, but rather to remove the sulfur scubbers.

Getting back to basics, the bottom line is that AGW made a number of predictions. The predictions have not been observed, the theory has been falsified.

Note that this is separate and apart from whether it makes sense to invest in alternate energy sources. The reality that AGW has been falsified does not change the fact that these are good things to do. Just let's not all go crazy, okay?; 7/13/11, 1:52 PM

This is why my test proposed setting the success criteria before performing the test.

Global cooling is a serious problem right now. The cold fronts came down and made snow accumulations that lasted past July 4th and then released flood waters filling up every reservoir, lake and river front town in sight.

The Cooling is slowing down seed germination until the crops will not get a full growing season in before harvest. Food prices are already skyrocketing.

Droughts exist in spots along with heat spots in June through August , but they were much worse in the 1930s and the 1950s. In Atlanta we had the highest temp ever measured here in July 1952, at 107F. (FYI, we had no AC then.)

The ability of traces of co2 to trap any heat is doubtful at best. And if it were happening, then it would happen first in the upper atmosphere , and it has not happening.

Revenant said...: Gabriel,

A couple of points about your RealClimate link.

First of all, it is from 2007. The accuracy of model worsened considerably in the late 00s due to the temperature anomaly of those years (global temperatures cooled for unknown reasons).

Secondly, even if Hansen's model had remained highly accurate up through the present day, that does not reflect on the quality of climate research as a whole. Take economics, for example -- you can look at any five, ten, or twenty-year period of economic performance and find an economist who (a) predicted it and (b) has a model explaining why. It doesn't mean his model is good; it means that there are a lot of economists making a lot of wildly differing predictions, and thus it is guaranteed that one of them will turn out to have guessed right.

Thirdly, the ability to make an accurate five, ten, or twenty-year prediction does not imply the ability to make an accurate fifty or hundred-year prediction. It doesn't even imply the ability to make an accurate 25-year prediction.

Finally, option B on Hansen's chart was the prediction assuming linear growth in concentration of the major greenhouse gasses. Option A assumed exponential growth and predicted more warming. Atmospheric concentrations of greenhouse gases have grown exponentially since 1984, not linearly (although not at the rate option A used). Thus the actual temperature, per Hansen's model should be *warmer* than option B.; 7/13/11, 4:46 PM

James Hansen is probably a prime example of this. He's so immersed in his doom and gloom point of view that, whatever expertise he has, to listen to him on policy is probably a terrible idea.

rhhardin said...: @Gabriel Hanna@rhhardin:blah blah Navier-Stokes

This SOUNDS like a scientific criticism, but tis't he same thing as saying "if we can't predict weather we can't predict climate".

If the Navier-Stokes equation that govern climate couldn't be approximated, then there would be no such thing as "climate". The waether would never settle down enough to be considered "climate".

But because over long times and large distances the instabilities work themselves out, there IS such a thing as climate and it CAN be modeled.

The blah blah part is the interesting one.

The Navier Stokes equations in three dimensions moves flow scale sizes to shorter and shorter distances. That results in a flow that no computational grid is fine enough to resolve.

So, roughly, your numerical solution is good for about as long as it takes for the flow to cascade to the scale size of your computational grid.

Nature has no problem with this: additional resolution is available to nature whenever it wants.

But you can't solve the Navier Stokes equations numerically.

As you double the resolution, you do not converge on the true flow, which has the same error no matter how fine you make your grid.

Why do you need such fine resolution? Because it works back on the larger flow as sort of a pseudo-viscosity and changes the larger flow.

In two dimensions, by the way, flow tends to larger, not smaller, scales, and so can be done pretty well.

Anyway, look up any model for global warming that's remotely based on the Navier Stokes equations, and you'll find viscosities that they pull out of their asses and large grids.

That's the tip of the iceberg, but a mathematical point that's irrefutable.

People actually curious about atmospheric flow work on considerably smaller problems. The point of computation for them is understanding, not numbers.
