You are making me laugh now smile.png Excerpt from your link." A survey of all peer-reviewed abstracts on the subject 'global climate change' published between 1993 and 2003". Now here is a excerpt from the link im about to provide. “oth poles have expanding ice, with the Antarctic breaking all time records, global temperatures have failed to rise for 15 plus years, global cooling has occurred since 2002, polar bear numbers are increasing, wildfire’s are well below normal, sea level rise is failing to accelerate, tornadoes are at record lows, hurricanes are at record low activity. "

Are these anomolies? I think not! Really we could use some global warming. Lots of growth, water, food, warm temperatures, can keep a tan. Sounds much better than the"reality" and emprical evidence showing otherwise to your consensus. I will stick to observable recorded evidence than Global Warming Theory. As actual is observable. While some scientists agreeing to a view based off of faulty computer models is definitely debatable!

How does that in any way rebut the fact that >95% of scientists in the field agree that AGW is a thing?

 

Good Luck trying to get some believers!

This isn't about belief, and since the vast majority of the scientists are already "on our side" getting more would actually be a problem.

Now you are making things up. Proof of 95% of scientists in the field agree? Following the same suit as the Global Warming Scientists? Making things up then calling it fact? 95% of scientists agree the earth is round too! Does not matter! What does matter is real empiracal evidence to support the claim. Not faulty unproven and broken Climate Models which have been shown to be false over and over again.

 

This isn't about belief, and since the vast majority of the scientists are already "on our side" getting more would actually be a problem.

Once again, another assumption, as well as a misdirection.

 

Now here is a list with credentials of scientists who differ from your view. By the way, this is just a sampling as it comes from wikpedia.

 

 

Scientists questioning the accuracy of IPCC climate projections

Scientists in this section have made comments that it is not possible to project global climate accurately enough to justify the ranges projected for temperature and sea-level rise over the next century. They may not conclude specifically that the current IPCC projections are either too high or too low, but that the projections are likely to be inaccurate due to inadequacies of current global climate modeling.

Scientists in this section have made comments that the observed warming is more likely attributable to natural causes than to human activities. Their views on climate change are usually described in more detail in their biographical articles.

Scientists arguing that the cause of global warming is unknown

Scientists in this section have made comments that no principal cause can be ascribed to the observed rising temperatures, whether man-made or natural. Their views on climate change are usually described in more detail in their biographical articles.

you can find this list at http://en.wikipedia.org/wiki/List_of_scientists_opposing_the_mainstream_scientific_assessment_of_global_warming

 

Then you have this http://www.climatedepot.com/2010/12/08/special-report-more-than-1000-international-scientists-dissent-over-manmade-global-warming-claims-challenge-un-ipcc-gore-2/

 

At least if you are going to give a argument. Back it up! Otherwise it can be viewed as lying or deception. The same practice the IPCC has been doing for the past 5 years. Like I said, you have shown nothing to support your claims. While all anyone has to do is google the empirical evidence of the past 15 years for mine!

If I counted correctly that's 35 scientists who believe mankind is not responsible for global warming.

Swansont's contention is that something like 95 % of scientists don't agree with that opinion. That's about 1 in 20.

 

Your "evidence" is a refutation as long as there are no more than 20 times 35 scientists in the world.

 

Otherwise it's just a list of names.

A different list would be the authors of the IPCC's latest report. There are about 600 of them.

So, I can easily cite a group that suggests that Swansont's position is reasonable.

 

Incidentally, would you like me to check up on the credentials of those 35?

how many of their wiki pages include stuff like ". Tennekes objected to the increase of computing power for medium-range weather forecasting, because he considered this unnecessary. According to Komen, Tennekes supported this decision by referring to biblical texts."?

You actually cannot defend your position other than trying to defame other scientists in the community who oppose your view. Thats a shameful action on your part. It is one thing to debate with evidence(which none of you have shown any). But quite another to attack people who are not even in this conversation. Talk about low character. If you are going to attack someone. You had better make sure they are present to do such.

 

you did not look at the other link provided, I will give you a link with a report. http://cfact.org/pdf/2010_Senate_Minority_Report.pdf as I stated, the wiki was a sampling. This report is a bit more in-depth.

 

Also I still have to see the hard evidence of 95% of scientists in the field agree with global warming. I am providing evidence. But as of yet, those of you arguing have provided no names, no anything. Other than empty jargon and a report from 2003.

 

Also consider this new report: http://climatechangereconsidered.org/

 

 

Just a quote for you!

MIT Climate Scientist Dr. Richard Lindzen Rips UN IPCC Report: ‘The latest IPCC report has truly sunk to level of hilarious incoherence’ — ‘It is quite amazing to see the contortions the IPCC has to go through in order to keep the international climate agenda going’

The Consensus Project says they have examined 3,896 peer reviewed papers with 97% consensus that "Global warming is happening, and we are the cause."

 

 

Who contributed to The Consensus Project?

The Consensus Project was a citizen-science effort that took over a year from beginning of the project until submission of the paper to the journal Environmental Research Letters. 24 volunteers contributed to the rating of the papers. Half of the raters completed 97.4% of the ratings. All of the major contributors to the project are named as co-authors or thanked by name in the Acknowledgements of the full paper.

 

In order to invite scientists to self-rate the level of endorsement of their own papers, 40 volunteers helped collect over 8,000 scientists’ emails. A total of 1,200 scientists responded to the invitation with over 2,000 papers each receiving a rating from the paper’s author.

 

It was very important to the volunteers at The Consensus Project that our published paper be freely available to the public (unfortunately, many peer-reviewed papers are hidden behind a pay-wall). For this reason, we chose the high-impact journal Environmental Research Letters, which charged a $1,600 fee to enable the paper to be open-access. This fee was crowd-funded by donations from Skeptical Science readers. The funds were raised in 9 hours.

 

The importance of raising awareness of the scientific consensus on climate change cannot be overstated. Typically, the general public think around 50% of climate scientists agree that humans are causing global warming. The Consensus Project has shown that the reality is 97%. To help “close the consensus gap”, the website TheConsensusProject.com was created pro-bono by the New York-based design and advertising agency, SJI Associates.

I dont really believe in man made climate change other than erosion caused by populace and farming.

 

Really? You think this planet can be occupied by a primate species with a population of more than 7,000,000,000 and not have any more effect on the environment than erosion? Mankind certainly contributes to climate change, only the magnitude of that contribution is debatable. One thing is not debatable though, the magnitude of mankinds pollution of the environment that we depend on for life. We're not just pissing in our bathwater, we've consumed an overdose of laxative so that we can make it toxic to life as we know it. As a whole we're proving to be a very irresponsible species on our host planet.

Talk about another piece of false claims. A little frustrating, but here we go again.

Will help the reader undestand why this report is "FALSE".

 

First the claim.

 

Claim: 97% of papers published on Global Warming agree Global Warming is man-made.

 

Reality: That is 97% of the almost 4k papers made by 1200 respondents who were involved in the project. That is not a 97% of the papers peer reviewed world wide or a consensus among the the global scientific community. Rather they are peer reviewed papers by those involved with the project

The premise is both misleading and dishonest. Which as of late has been the usual norm IPCC and most global warming activists. This supposed fact" 97% of papers published on Global Warming agree Global Warming is man-made"is scientifically FALSE!

 

Continuation, using the reports own data. of the 8000 scientists only 1200 responded to paticipate in the project. That leaves 6800 who said no, not interested, or disagree with the premise. That is just among those scientists contacted.

 

Next, the peer reviewed papers themselves. A excuse of a pay wall does not articulate fact. As far as any reader is concerned a paper could be a picture of Micky Mouse holding a lit match. The reality is without actual support to the claim of AGW. It is still just hear-say. Which is not Empirical evidence. Regardless of how much or how many supposed papers that validate the claim. If they are not observable, they are not evidence.

 

I do not understand why some here cannot use logic or articulate to dispose a fudged fake advertisement such as the "Consensus Project" is.

I guess people buy into anything if it suits his or her beliefs or agenda!

 

Very embarassing if you believe that project!

I agree, I never said that mankind does not contribute to the pollution and erosion that takes place in the world. You should perhaps read my article again. As I believe you may have missed some of the other things said in it.

No, I didn't just question the reliability of your "experts"

I pointed out that , from a field of countless thousands of scientists, you can come up with a few dozen who support your belief and you pretend that those handful are enough to detract from the fact that the overwhelming consensus among scientists is that the world iw warming and we are at least partly responsible.

 

You said I can't defend my position.

Well saying that is obviously wrong. I had just defended it when you wrote that rant.

Were you lying deliberately, or did you just not understand that your were obviously utterly wrong?

 

Also, please learn to use the quote function correctly. As it stands you have falsely attributed some of your gibberish rant to me.

jduff, Now you quote me and add your own statements in the post. That is dishonest, even though you put your statements in red, you do not identify them as yours. I said that people can read the website and make up their own mind whether they have done a good job. Your statements in color red, extracted into the above quote, conclude things the web site does not say.

You're missing his point. You should not put your words inside your quotations of another members post. See how my comments are outside the part of my post that quotes you. There is no ambiguity on what you have said or what I have said.

My point was that your post did nothing to rebut iNow's point about the vast majority of the scientific work on the topic agreeing on AGW.

 

For all of your denialist ranting about empirical evidence, you have not presented any that shows warming hasn't happened, or, if you agree it has happened but not anthropogenic, what the source of it is.

We know that there's roughly a third more CO2 in the air than there used to be. (The measurements way-back might be a little less precise than today's, but the general estimate would be pretty close to correct)

 

We know that this additional CO2 is due to our burning of fossil fuels. (Essentially, we know this because we paid tax on those fuels so they were quite well documented, but the radiocarbon signature also shows that this additional CO2 is geologically ancient).

 

We know that CO2 acts as a "greenhouse gas"- it absorbs infrared radiation.

 

We know that such IR absorbing gases will warm the earth.

 

We know that the earth is warming.

 

How do you come to the conclusion that we are not responsible for that warming?

Adding to John's point is man's indirect contribution of methane which is 25 times as potent as CO2 as a greenhouse gas. Mankind farms livestock the world over to support the dietary needs of our exponentially growing population and that livestock emits a noticeable percentage of the methane in our atmosphere.

They used "globally averaged well-mixed marine boundary layer CO2 data". Is there a time lag between atmospheric increases and well-mixed oceanic increases?

 

Does subtracting on a 12 month basis introduce any aliasing effect on the increase?

 

Why analyze the increase? Isn't temperature said to correlate to CO2 levels, not changes in CO2 levels?

OK, the first page cited starts with,

"CO2 released from use of fossil fuels have little influence on the observed changes in the amount of atmospheric CO2 "

which is wrong.

As I already pointed out, you can carbon -date the CO2 that has been added to the air. It's old, soi its origin ie geological rather than oceanic.

 

It also says

"Prior research has shown infrared radiation from greenhouse gases is incapable of warming the oceans, only shortwave radiation from the Sun is capable of penetrating and heating the oceans and thereby driving global surface temperatures. "

which is silly.

The whole point about the greenhouse effect is that the sun warms the earth. The greenhouse stops the heat escaping.

 

 

The second web page says things like

"However, since the LWIR re-radiation from increasing 'greenhouse gases' is only capable of penetrating a minuscule few microns (millionths of a meter) past the surface and no further, it could therefore only cause evaporation (and thus cooling) of the surface 'skin' of the oceans."

which are unrealistic.

Heating the surface of the ocean makes it hotter.

It also makes the underlying water hotter by conduction.

The only way it could promote evaporation would be by heating.

 

Incidentally, that page also cites this guy

http://en.wikipedia.org/wiki/Roger_A._Pielke#On_climate_change

He doesn't support your ideas that people are not responsible for climate change.

When you are citing people who don't agree with you in support of your ideas, it's probably time to find some better ideas.

 

I'm glad you find science funny.

There's not a lot of science in the pages you linked to- why is that?

 

 

Anyway, rather than posting links to stuff that doesn't stand up to any sort of analysis, why don't you answer my question?

Why don't you believe that the additional blanket we have put on is the reason we are hotter (and, yes- we are hotter- that's essentially the point Swansont is making)?

I hadn't read the second link when I posted. Yes, it seems that they are arguing that putting on a coat won't keep you warm when it's cold out, since the coat will be at a lower temperature than your body, and thus cannot transfer heat to you. And while that last part is true (2nd law of thermodynamics), it points to a fundamental misunderstanding of the whole process of why insulation works.

The bolded & underlined sentence, whoever said it, is false.

 

 

 

PROF GRAHAM FARQUHAR: There is a paradox here about the fact that the pan evaporation rate's going down, an apparent paradox, but the global temperature's going up.

NARRATOR: This was a puzzle. Most scientists reasoned that like a pan on the stove, turning up the global temperature should increase the rate at which water evaporated. But Roderick and Farquhar did some calculations and worked out that temperature was not the most important factor in pan evaporation.

DR MICHAEL RODERICK: Well it turns out in fact that the key things for pan evaporation are the sunlight, the humidity and the wind. But really the sunlight is a really dominant term there.

NARRATOR: They found that it was the energy of the photons hitting the surface, the actual sunlight, that kicks the water molecules out of the pan and into the atmosphere. And so they too reached an extraordinary conclusion.

From this

http://en.wikipedia.org/wiki/File:Heat_of_Vaporization_(Benzene%2BAcetone%2BMethanol%2BWater).png

Near room temperature the heat of evaporation of water is about 44KJ/mole

 

According to this,

http://en.wikipedia.org/wiki/Joule_per_mole

That's about 0.5 eV per molecule

Which corresponds to a wavelength of about 2.4 microns

But the radiation they are talking about has a wavelength in the range 8 to 14 microns.

So it simply doesn't have enough energy to evaporate the water except if a bunch of photons are absorbed and their collective energy is used to drive the evaporation.

That's called heating up.

And I don't care who says otherwise, even if it's on the BBC, if the energy isn't there- it doesn't happen.

Direct evaporation by shorter wavelength IR or visible light is possible- but that's not the range these guys are talking about.

My bad. I thought the theme was to be objective. Carry on then.
