Yea, and everywhere I read these studies on the effects of CO2 on plants involve anti-GW websites.
Yes, you will see a lot. But you an also find it on government websites, gardeners websites, even canabis growers websites. CO2 enrichment has been used for a long time in greenhouses (and no, thiose work differently to the greenhouse effect before you start drawing silly comparisons).

And crop yields don't need extra CO2.
No? How about feeding people.
ragnaroknrol wrote:
since less fertilizer would be needed
Could less fertilizer be used if CO2 was higher? I havent seen any studies on this, but its an interesting possibility.
ragnaroknrol wrote:
But you'll ignore this answer because it means changing habits and heaven forbid we have to do that...
No, not so. I am genuinely interested in the future of mans ability to feed himself and the world. I just dont think that issues like overpopulation and food supply should be confused with global warming.

Hold up a second. You have been throwing around some numbers about how we have increased CO2 in the air already. You also say it helps crops. But why hasn't this been evident all over the place then? If us dumping that much CO2 has not had any real impact on the environment, then how could it help crops? What, it selectively helps plants but doesn't do anything else? What levels of CO2 are we talking about? And has anyone bothered looking to see how much that level will change things? You can't have your cake and eat it too, this is pretty much a universal truth. If this stuff does one thing positively, I want to see what the side-effects are.

To complicate it more, we have these short-term cycles on top of the big ice age cycle... Cycles inside cycles... And out of all this, we're trying to measure how much effect we've had in only the past 100-130 years. Not so simple.
Yes, this sums it up pretty well. If you lok even further back, over the last 10,000 years at the ice core data you can see a gradual decline in temperature. And we dont know why. Yet we are content, aparently, to worry about a 30 year trend showing a slight increase. That, I dont get. Yes, good link. Here is a snippet "One suprise may be that the earth receives almost twice as much heat from the atmosphere as it does from the sun. But the sun only shines on a given point on the earth half the time, while the atmosphere radiates continuously" I would want to see a measurement of the heat received from the sun at the top of atmosphere to make sense of this because no where does the second respondant list LongWave radiation from the sun as an atmosphere gain. From earth yes, but not from the sun. And the sun produces more of it. This is the bit I think is missing in all the calculations regarding GW.

I think you might be incorrect on that point. I knew something didn't seem right about your numbers... From my understanding, and the info I've found, most of the radiation from the sun is in the form of visible light and UV, not infrared. "The sun, which is very hot, emits high energy, shortwave radiation, while the earth, which is much cooler, emits lower energy, long wave radiation." http://earthobservatory.nasa.gov/Experiments/PlanetEarthScience/GlobalWarming/GW_Movie1.php#[^] Hence most of the heat coming from the sun is in the form of visible light and UV, which passes right through most of the greenhouse gases, for the most part. The heat remitted by the earth is more in the infrared range, so is absorbed by the atmosphere (Note the previous link saying that only 4.1% of the heat from the earth goes directly out into space).

Hey, if you havent realised, GW has fallen apart. Even the ex Climate chief, now labled a criminial for breaching FoI laws, states the recent warming is stastically indifferent to the previous three warmign cycles in the last century and a half. And as for the IPCC, there have been so many errors found in its 4th AR it is now a joke and even IPCC members are calling for Pachuri to resign. You think I dont have perspective?

When we talk climatic warming, we're not talking about tens of degrees, we're talking fractions of a degree. Oh, and by your reasoning that the radiator has to be hotter than the heat it's transmitting, then by that graph, the troposphere is around -8 degrees Fahrenheit, so it can't possibly be radiating heat back. Once again, you've shown us a clear misunderstanding of the greenhouse effect.

So, here's the original article from 2002: Antarctic climate cooling and terrestrial ecosystem response[^] And here is a second article published last year: Warming of the Antarctic ice-sheet surface since the 1957 International Geophysical Year[^] A true researcher doesn't just find whatever article he can on the internet and take it as truth.

True. But that doesnt mean it emmits less IR than the earth, it just means the greater part of a bodies radiatin curve moves towards the visble as it gets hotter. Look at the radiation curves for black bodies at various temperatures. You will see what I mean. I found an online Plank law calcularor. You can enter the temperature of th eblack body, the wavelength range, and calculate the energy produced. If you do the same you will see what I mean. You can also use the heating up a poece of steel analogy I told you about earlier. The skin is a good IR sensor. As steel heats up it feels hotter and hotter, eventually starting to glow red at about 600`C. You can FEEL the increase in heat coming off it as it heats up. All in the IR. Check out what I say here, its true, and I think quite important.

Here's a nice chart... http://earthguide.ucsd.edu/virtualmuseum/images/RadiationSpectrumEmittedFromSun.html[^] The curve on the left is the radiation coming in from the sun, mostly in the visible and near-infrared range. Light, not heat. The curve on the right is what the earth is sending back out, notably WAY over in the infrared spectrum. For reference, this chart[^] from Wikipedia shows just the sun's incoming radiation, along with where infrared starts. Note that most of the absorption is actually from water vapor, but we're discussing CO2 here... CO2's absorption is centered on a relatively narrow band way over in the far-infrared range... Not much comes in from the sun at this wavelength, but a significant amount radiated by the earth. So basically, most of the radiation from the sun comes right in, while a lot of the radiation from the earth is trapped by the atmosphere. That's the greenhouse effect, and that's why more CO2 heats us up instead of cooling us down.

I can see you are a firm AGW belilever and will not be shaken. You will interpret everything I write according you your belief and will not look ay one sinlge link I provide to back up my claims. You do not want to be aware that the ex Clmate chief, Phil Jones called the recent warming 'stastically insignificant1 and that there has been no significanty warming since 1995 and that the scientific debate is far from over. That Bob Waton of DEFRA states that there is no way to explain the recent warming and therefore it must be due to man made CO2. You do not want to know that GISS and NCDC use 90% less stations today to prepare their data sets than they did in 1980 depite GW being spposedly the most important issue in the history of mankind. You do not watn to know that the IPCC has used non peer reviewed worl for its 4th AR and intentionally lied about glacier shrinkage in order to gain attention, and thus funding in exactly the samer way the UN did with aids. You will ignore all this and continue to insult me because it runs counter to your belief system. You needent bother to respond to this, I am not going to discuss GW with someone so intentionaly blinkered.

Here is some evidence. For more than 20 years forest ecologist Geoffrey Parker has tracked the growth of 55 stands of mixed hardwood forest plots in Maryland. The plots range in size, and some are as large as 2 acres. Parker's research is based at the Smithsonian Environmental Research Center, 26 miles east of the nation's capital. Parker's tree censuses have revealed that the forest is packing on weight at a much faster rate than expected. He and Smithsonian Tropical Research Institute postdoctoral fellow Sean McMahon discovered that, on average, the forest is growing an additional 2 tons per acre annually. That is the equivalent of a tree with a diameter of 2 feet sprouting up over a year. [^] As for crops, perhaps the effect has been hidden by the increase in use of fertilizers. After all, global crop yields have gone up by a huge amount since the 50's. However, and I have already told you this, CO2 has been used in greenhouses for a long time in order to increase crop yields.

Go back and read again what I have written. You will see that I state that there is evidence of increased plant growth.

Well, the Canadian government talks about 1300 ppm as an optimum for plant growth. I am talking about curent CO2 levels, so thats 380 ppm, abd the effect they have already had on forest growth.

Ah such well-founded debate. Thank you for that...gave me a little chuckle this morning! Did I say anything about how you make your money? Umm...no...I was talking about educational background. As in, what is your formal training in? And you're question about how much "meteorology" have I studied shows just how little you understand what "environmental science" is or this debate. Meteorology is the study of weather. From Wikipedia: "Meteorology is the interdisciplinary scientific study of the atmosphere that focuses on weather processes and forecasting (in contrast with climatology)." Note the "in contrast with climatology". We're talking climate not weather. And, you can bet that anyone with an environmental anything degree has had the basics of the greenhouse effect and the effects of greenhouse gases on the atmosphere. From Wikipedia again: "Environmental science is an interdisciplinary academic field that integrates physical and biological sciences (including physics, chemistry, biology, soil science, geology, and geography) to the study of the environment, and the solution of environmental problems. Environmental science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems[1]." EnvSci is concerned with how everything interacts with everything else on a local, regional, ecosystem, and world scale. And, yeah, I'm "trained" to "test" theories using scientific techniques. But to begin to "test" a theory, you first have to understand it, which you clearly do not. And scientific testing does not involve sticking your head out a window and saying, "Hmm...it feels the same today as it did 20 years ago!"

No, the earth emits about as much energy as IT RECEIVES from the sun. This is basic conservation of energy. If the earth is going to remain at a relatively constant temperature, then the energy going in and the energy going out must be about equal.

Yes, I know, that's one of the other graphs I looked at... Thought I had included that one in my post, but I guess not. Note that only a tiny amount is absorbed by CO2 coming down, because very little of the incoming radiation is of the right wavelength for CO2 to catch. The energy going back OUT (Radiated from the earth) is more concentrated in CO2's absorption band, so a large amount is blocked.

Well, the fundamentals of GW theory are not hard to understand. I just believe they have completely overloofed solar IR, as you will no doubt agree with if you looked at the informaiton I gave you earlier. As for our friend with the environmental qualification you yourself replied saying that you thought he was wrong that only qualified people are capable fo discussing a subject. I agree with you, and I also dont think that a broad environmental study such as he did that include biology necessarially qualifies him as an expert in thermodynamics. And really, this ia what GW is all about. Heat. And its transfer.
Ian Shlasko wrote:

Yes. AGW is nothing but a political agenda. Any course that promotes AGW is therefore biassed. That might be a little hard for you to swallow, and I am not a right wing loonie, but I do seriously believe that the damning of CO2 was carried out entirely to attack western consumption and bring about a redistribution of wealth on a global scale through carbon taxation. In fact an advisor to Thatcher, Lawson, has stated that she paid the Royal Society (scientists) to demonise CO2 in order to promote nuclear power over coal as a way of destroying the coal industry and its very powerfull union, lead by Scargil. She went on to play a big part in the formaiton of the IPCC and this explains why the first chairman was British and why a British university today, East Anglia, suplies the IPCC with temperature data. Anyway, back to education being pliticised... OK, lets take it from another angle. The UK government wanted to show Al Gores An Inconvienient Truth in all schools. In fact, in some private schools it was being shown as part of I believe three different courses. The government was taken to court by a lorry driver (admittedly funded by a group). Al Gores film was hence judged to contain 9 seriou

4/5ths of factors afecting climate have a "very low level of scientific understanding" to quote an IPCC graph. I would provide a link to it on their website but they have recently moved a lot of stuff around and broken it.

Well, the fundamentals of GW theory are not hard to understand. I just believe they have completely overloofed solar IR, as you will no doubt agree with if you looked at the informaiton I gave you earlier. As for our friend with the environmental qualification you yourself replied saying that you thought he was wrong that only qualified people are capable fo discussing a subject. I agree with you, and I also dont think that a broad environmental study such as he did that include biology necessarially qualifies him as an expert in thermodynamics. And really, this ia what GW is all about. Heat. And its transfer.

Yes, I did at first disregard solar IR, but then I did some research, and learned that it's relatively minor, compared to the other factors involved.

No. The people ADVOCATING a certain theory may have political viewpoints, but science is science. I don't care whether you agree with it, but IF the facts support AGW, then AGW is correct. If the facts oppose AGW, then AGW is wrong. Facts are all that matter. You need to learn to separate the people from the science.
Proud to have finally moved to the A-Ark. Which one are you in?
