Is news coverage of stories global?

- This study from 1992[^] suggests that too much CO2 might hurt plants. 2) This[^] more recent one suggests similar, when combined with other likely consequences of climate change (Higher temperatures, increased precipitation, more nitrogen in the soil) 3) This study[^] shows that increased CO2 helps plant growth, but lowers quality. It does mention that this study did not include increased temperature as a factor - Just higher CO2 concentration. 4) This study[^] seems to support your position, that it would increase plant growth. So I'm seeing research on both sides of the issue. Now I'm not saying you're wrong, but I don't think we can consider your position to be a "fact." It may be true, or it may not be. At this point, I consider it in dispute.

I found an interesting article on the Canadian governments website about using CO2 in agriculture, I recall that at high levels it caused some plants to become brittle. But I believe those levels were a lot higher than the 1300 ppm they recomend. Those first links are interesting. Thanks. The only counter argument I have is that for decades CO2 has been used in greenhouses to increase crop yields. I will look som more at what you found there. Could be there some types of plants that dont do so well, although this is the first I have heard of it.

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.

I dont get your point about loooking at short term cycles though, what do you mean?
From what I've read, climate doesn't seem to be a steady thing. Everything works in cycles... That's why some years are warmer, and some are cooler. I've seen this used to support either side of the debate, actually... Some AGW advocates claim that we're on the down-sloping part of the cycle, but it isn't decreasing fast enough. Some anti-AGW advocates claim that we're just seeing warmer temperatures because we're in the upward-sloping part of it. It's also what makes the results of these studies difficult to read. As an analogy, look at the economy... Forgive the US-centrism, but here's a graph of the Dow Jones Industrial Average (One of the "standard" indicators of the US economy): 1900 - Present[^]... An obvious upward slope, because of inflation. This is the "big picture" in terms of economy. But as we know, the economy works in short-term cycles, so you can change the picture by looking at a smaller range: 2000 - Present[^]. Now you see the big crash from last year... And now it's not that obvious whether we're going up or down. Same thing with the climate (Though not such an obvious long-term trend)... Depending on what period you look at, you can alter the results. There was a debate in the back room a a couple months ago, I believe, where people were talking about the infamous "hide the decline" scandal (Which was just bloody ridiculous - Total misinterpretation). People were playing with the model, and realized that if you change the measured date range only slightly, it completely changes the outcome. Pick a year, and you can engineer your results. You can say the temperature has decreased since the 30s, or you can say it's increased since the 1850s (Just as an example). 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.

Where he got:"The theory of GH gass warming states that the cold periods and regions will be affected more than the warm." bewilders me or that the troposphere would have to warm substantially for it to be greenhouse gases.
OK, now down to the facts. Greenhouse gases trap heat within the surface-troposphere system, causing heating at the surface of the planet [^] So, since the surface doesnt contain any CO2, it is the troposphere that traps the heat. This heat is then radiated towards the surface. A radiator has to be hotter then the receiver of the heat, otherwise the heat would flow the other way. This is why the troposphere has to be HOTTER than the surface. As fopr polar warmihg, here is a snippet from Nature, quoted here many climate models indicate that the Polar regions should serve as bellwethers for any global warming trend, responding first and most rapidly to an increase in temperatures[^] Thats BOTH polar regions, not one. Its GH gass theory 101. I am surprised, since you have studied 'environmental science', that you dont know this. I would have thought basic GH gas theory would have been part of you sylabus.

Did you know that that information came from the IPCC which you so clearly despise? Here's a graph of daily mean tropospheric temperatures[^]. 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.

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.

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).

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.
Proud to have finally moved to the A-Ark. Which one are you in?

This happens a lot with conservatives. They attack something, put some little dig in with crap science or something stupid like "Al Gore said it would never snow again thanks to Global Warming. HE LIED!!!" and then expect everyone to believe them. Aside from website cherry picking quotes, misrepresenting quotes or just plain attacking everything because they don't believe it, I am not seeing much out there saying it. And don't call me your friend. Edit: Oh and before I forget. I don't care if it was for "banter". Banter does not consist of personal attacks in response to someone puting their credentials out there. This was not "banter" it was you realizing you aren't going to come close to winning a rational argument with a guy that knows more about the subject than you do so you called him a tree hugger. It was an attempt to demean his expertise to prop up your argument. Have the integrity to at least admit when you are an ass.
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.
