are you going to show the evidence, or just continue bloviating from the balcony to your fellow cultists?

Can i suggest you review all of the threads we have participated in over the last five years with an open mind.

Can i suggest that you take a note of the number of times you have been shown to be factually incorrect and then how many times you acknowledged your mistake.

Do the same for me and Doug.

Stonewalling and denying that these points have all been discussed before, at length, discourages me from spending any time showing you anything. I will restrict myself to correcting you when you make an obvious factual error so that others might learn.

Anything else is a waste of time and I hate going over the same things again and again for someone who will not accept scientific papers as evidence of facts.

The psychology of a person who would make a statement of fact and then refuse to support it with evidence interests me. it suggests a lack of confidence in t6he basic facts.

How about that clean coal thing/

what more proof does anyone need that there is no empirical evidence that man has any significant effect on climate than to read the last few pages here.

Because we are bored with you games Little Fish you conclude that climate change isn't real :w00t:

What have you been wrong about over the last 5 years ? Do you want me to list some relevant examples ?

Can we start by asking you a few questions.

Do you accept that CO2 is a greenhouse gas ?

Do you accept that mean surface temperatures have risen over the last 100years ?

Do you accept that there is a net energy imbalance at the top of the atmosphere ?

Do you accept that the total heat content of the planetary system has risen over the last 100years ?

Do you accept that man has contributed to a rise in CO2 through fossil fuel emissions ?

Do you accept that a portion of the global rise in surface temperature and energy content can be attributed to mans activities ?

Do you accept that the surface temperature record over North America is an accurate reflection of the real rise in surface temperature and if not why ?

Do you accept that the summer arctic sea ice extent has shown a downward trend for over a hundred years, and that the arctic glacial ice is at its lowest point for at least a 1000years ?

Do you accept that in local regions there has been an upward trend in extreme precipitation events and droughts ?

Each one of these points builds to an understanding of climate change and it is important to understand that there is no simple single piece of evidence which proves AGW.

Some unrelated questions:

Do you accept that a countries population can continue to rise for decades after its fertility rate drops below replacement ?

Do you accept that Dr Wakefield had insufficient evidence to link the MMR vaccine to autism when he announced such a link in his famous press conference ?

Do you think that vaccines have contributed to an increase in world population or a decrease ?

I was just reviewing one of your thread on Bill Gates using vaccines as a means of population control. You used the same obfuscation tactics there, until a senior moderator concluded that you weren't serious about discussing the issues. You have form.

No ones going to learn anything about climate change through a discussion with you so I thought I would just have a Little fun showing how you are capable of swearing blind that basic empirical evidence is wrong.

it seems i'am about one of the only people left on these boards who is prepared to enetertain any sort of a discussion with you, even I get bored of never getting you to accept when your incorrect in your evidence.

So Little Fish - how is Bill Gates killing off the world through vaccines ??

hows that whole population control thingy going anyway - seems all the evidence shows its been a bit of a failure - what with the growing population and all that :w00t:

Hey Little Fish, I told you how i am going to play the game from now on - if you don't like it then buzz off.

Meanwhile its important to establish the credibility of you opponent before entering into any discussion.

The simple fact is, I don't like you, I don't think your honest and I don't think you know what credible evidence is. I am quite capable of disagreeing with someone and ending up shaking hands over the disagreement - if I think they have been honest in the debate and acknowledged the others point. You consistently fail on that count in all your debates with everyone.

It gets boring.

I'll wait for you to prove AGW is a lie, and then prove you wrong :tu:

This paper and the recorded increase in ocean heat content should be all the evidence anyone needs to accept that AGW is real;

Increases in greenhouse forcing

inferred from the outgoing longwave

radiation spectra of the Earth in

1970 and 1997

The evolution of the Earth's climate has been extensively

studied and a strong link between increases in surface temperatures

and greenhouse gases has been established3,4. But this

relationship is complicated by several feedback processesÐmost

importantly the hydrological cycleÐthat are not well understood5

±7. Changes in the Earth's greenhouse effect can be detected

from variations in the spectrum of outgoing longwave radiation8

±10, which is a measure of how the Earth cools to space and

carries the imprint of the gases that are responsible for the

greenhouse effect11±13. Here we analyse the difference between

the spectra of the outgoing longwave radiation of the Earth as

measured by orbiting spacecraft in 1970 and 1997. We ®nd

differences in the spectra that point to long-term changes in

atmospheric CH4, CO2 and O3 as well as CFC-11 and CFC-12.

Our results provide direct experimental evidence for a signi®cant

increase in the Earth's greenhouse effect that is consistent with

concerns over radiative forcing of climate.

More energy is been trapped in the planetary system by an increase in long wave absorbtion due to greenhouse gas increases and this is finding its way into the oceans, which in turn is heating the surface air.

It seems that UM is slightly off the general feeling in the general populaztion of the US regarding the reality of climate change.

Here we have 62.5% accpting AGW, but in the general population that rises to 80%.

"

Phil Adams, a retired freelance photographer from Washington, N.C., said he was "fairly cynical" about scientists and their theories. But he believes very much in climate change because of what he's seen with his own eyes.

"Having lived for 67 years, we consistently see more and more changes based upon the fact that the weather is warmer," he said. "The seasons are more severe. The climate is definitely getting warmer."

"Storms seem to be more severe," he added. Nearly half, 49 percent, of those surveyed called global warming not just serious but "very serious," up from 42 percent in 2009. More than half, 57 percent, of those surveyed thought the U.S. government should do a great deal or quite a bit about global warming, up from 52 percent three years earlier."

It seems the denial publicity steamroller is running out of steam and the tide has turned towards accepting the reality of their own eyes.

even if you assume that comparing and finding small differences between two different measurement systems means anything, the paper does not answer the question of whether man's co2 has an affect on climate worth worrying about.

I'd also question whether that paper was properly peer reviewed given the graph in fig 1a has the IMG and IRIS satellites labeled incorrectly. something like this should have been picked up by a reviewer if the reviewer had understood what he was reading.

"The conclusion as stated is somewhat misleading. It does not provide direct experimental evidence for a significant increase in earth's greenhouse effect. It does so only for the cloud-free part of the atmosphere located over a portion of the planet's oceans. And for such circumstances, the authors' results are exactly what we would expect: over the 27 years in question, measured increases in the atmospheric concentrations of the gases mentioned should indeed have increased the greenhouse effect of the pristine cloudless atmosphere.

This finding, however, tells us nothing about earth's climatic response to the inferred increase in radiative forcing, which is what the climate change debate is all about, i.e., trying to evaluate the competing effectiveness of various positive and negative feedbacks that come into play when there is a small change in the radiative properties of the cloudless atmosphere. In fact, the authors' finding is so rudimentary as to be essentially meaningless. Assuming, for example, that their handling of their data is correct - and this is a huge assumption they spend over half their paper discussing - they have simply verified the definition of the greenhouse effect!"

A very unconvincing response there Little Fish.

One small piece of evidence to which which supports the observation of the energy imbalance at the top of the atmosphere and attributes it to specific causes which are the change in absorption in response to increasing concentrations of anthropogenic CO2 and other greenhouse gases.

There are multiple other strands of evidence which demonstrate the existence of an energy imbalance at the top of the atmosphere so the paper quoted cannot be viewed and critiqued in isolation. Stratospheric cooling supports this;

dec_stratosphere.gif

Graph of measured stratospheric cooling.

http://www.wundergro...ato_cooling.asp

Stratospheric cooling is not a clear sky response so answers the other dubious critique of the original paper sited.

One set of measurements in isolation could be wrong, but when multiple strands of evidence point to an energy imbalance in the system it is far more likely that they are right. Picking holes in one analysis is only credible if the the same argument credibly explains the multiple other strands of evidence - which CO2science critique fails.

The attribution of those gases is further demonstrated by the changing isotopic ratio of the carbon and the lock step reduction of atmospheric oxygen concentrations. If there is an energy imbalance then it has to end up somewhere and the only place accumulating energy is the ocean - which is the main driver of surface temperatures.

The final response is indicated by the accumulation of energy in the system - which has and will continue to cause changes in the planetary energy flow systems - which by any other name is climate change.

The first fact demonstrates a net input of energy to the system, and the second shows where it is ending up. The critique you have referenced effectively denies the fact that energy is accumulating in the system - it tries to infer that the change in absorption has no net effect on the energy level of the planet when demonstrably the energy is accumulating. That is hand waving since it denies the evidence of the system response that has already been observed in an attempt to deny that there is any change in net energy input. to attempt such a stance requires another undiscovered source of energy input to the system to account for the accumulating energy which is observed - why go looking for another mystery energy input when the energy imbalance caused by CO2 is the most reasonable candidate.

The other effects of that change in energy are a whole other area of proof which flows from these two measurements. If you can't acknowledge that there is an energy imbalance in the atmosphere then you have stalled any meaningful discussion and we will end it there.

Global climate change results from a small yet persistent imbalance between the amount of sunlight absorbed by Earth and the thermal radiation emitted back to space1. An apparent inconsistency has been diagnosed between interannual variations in the net radiation imbalance inferred from satellite measurements and upper-ocean heating rate from in situ measurements, and this inconsistency has been interpreted as ‘missing energy’ in the system2. Here we present a revised analysis of net radiation at the top of the atmosphere from satellite data, and we estimate ocean heat content, based on three independent sources. We find that the difference between the heat balance at the top of the atmosphere and upper-ocean heat content change is not statistically significant when accounting for observational uncertainties in ocean measurements3, given transitions in instrumentation and sampling. Furthermore, variability in Earth’s energy imbalance relating to El Niño-Southern Oscillation is found to be consistent within observational uncertainties among the satellite measurements, a reanalysis model simulation and one of the ocean heat content records. We combine satellite data with ocean measurements to depths of 1,800 m, and show that between January 2001 and December 2010, Earth has been steadily accumulating energy at a rate of 0.50±0.43 Wm−2 (uncertainties at the 90% confidence level). We conclude that energy storage is continuing to increase in the sub-surface ocean.

The critique you have referenced effectively denies the fact that energy is accumulating in the system
there is no need to deny an increase in radiative forcing to show that the paper does not answer my question.

here again:

"tells us nothing about earth's climatic response to the inferred increase in radiative forcing"

right there, the logic assumes "an increase in radiative forcing" also stating the operative issue as "the earth's response" to it. so its not denied as you claim, but more importantly the paper doesn't show how the earth climate responds so therefore does not answer my question.

the radiative forcing from co2 is not enough in of itself to worry about, that's what the critique is saying here:

"...which is what the climate change debate is all about, i.e., trying to evaluate the competing effectiveness of various positive and negative feedbacks that come into play when there is a small change in the radiative properties of the cloudless atmosphere".

the debate is about the climate sensitivity to co2, whether the feedbacks are positive or negative, you need the feedbacks to be strongly positive.

here is the question again:

http://www.unexplained-mysteries.com/forum/index.php?showtopic=242505&st=75#entry4680450

your response does not answer it.

If you refuse to accept that there is a measured energy imbalance, and that energy is measured to accumulate in the oceans and atmosphere, then there is no possible way of proving "to you" that climate change is real.

The feedbacks are not significant in that the the response is been directly measured and the magnitude of the feedbacks are inferable from the measured response. Otherwise you have to invoke another energy source to account for the measured accumulated energy.

You position requires a denial of observational reality preferring to substitute unknown magical entities to account for the observed systemic change. You subsistute no account for the rise in system energy for a reasonable account.

You refuse to acknowledge basic factual axioms which are foundational on proving AGW. Therefore you are beyond reasonable debate on the subject and this discussion will simply circle. You have not critiqued the paper in any meaningful way, simply claiming that feedbacks swamp the response when the response is clearly measurable in the oceans. Your response is unable to account for those systemic energy responses and simply chooses to deny them. This has been you position for a long time, you deny CO2's effect but have no credible and consistent account for what is causing the accumulation of energy within the system - which to me is denial.

Let me ask you, what could constitute proof of AGW ? If you answer nothing - then we can end this charade now.

its the wrong question, it should be "dangerous AGW" not AGW.

I can heat the oceans by dropping a lit cigarette off the side of a boat, but there is no need to worry about a climate response to the cigarette.

that's false, i never claimed that.

i don't think you understand that CAGW or dangerous AGW requires a strong feedback, that's what the debate is about. the climate models have an in built strong feedback, they are not calculated, they are just assumed, which is why those climate models produce unrealistic and falsified projections.

this isn't 'debate'. it's rude, ignorant, arrogance.

seriously, why pander to an egotistical racist, who spends half his time slating the english, and the other half copy/pasting things he found on the internet like he's figured it out for himself? there's a name for a$$holes who

insult people with differing viewpoints br, see if you can guess what it is?

and please, don't try responding with your usual condescention, i'm above it.

you do yourself no favours whatsoever with your lousy attitude, and you lose whatever modicum of respect people have for you by being abusive towards everyone who doesn't agree with you.

I am English so i am entitled. I left England bacause I didn't like the direction the country is going in and have keenly observed the continued decline.

You should try engaging in a debate with Little Fish, as I have for five years.

You should also try to understand how you support an argument with credible references. Expressing opinions without evidence isn't productive since we can all have opinions no matter how unreal they might be. Conceding that you have been wrong on a point is how debate procedes and how you learn. if you never (ever) concede your position is flawed then you are not there to learn.

You earn respect through your deeds and that is why I cannot respect Little Fish.

The observed warming to the forcing is the basis for saying the feedbacks are strong.

Your expressed position is that AGW is not real and it is a plot to return us to a feudal social state - so your not been consistent here.

The concern is based on the observed warming which has already taken place not on some nebulous unmeasured warming. Your cigarette analogue is meaningless.
