150th Anniversary of Greenhouse Climate Theory 407
An anonymous reader writes "It was 150 years ago that John Tyndall, one of history's truly great physicists, published a scientific paper with the far-from-snappy title On the Absorption and Radiation of Heat by Gases and Vapours, and on the Physical Connexion of Radiation, Absorption, and Conduction. The BBC has an article on John Tyndall and his contributions 150 years ago to the physics behind the study of climate change."

What truly makes me sad when I see things like this, is that it ultimately makes me think that a bit of science has been lying around for 150 years - and there are still people who try to disclaim it, pretend it simply isn't true and make all manner of excuses as to why it doesn't mean what it clearly states. All to either keep making money, keep doing what they have been doing or because it is simply easier to not have to change the way things are done.

All water both reflects and absorbs radiation. What is particularly, spectacularly interesting about water's absorption spectrum is that it soaks up UV more effectively than any other frequency of light. When it absorbs UV it radiates IR, as you might expect. Now, solid water is quite good at reflecting radiation including UV, which is why the melting of ice on land is so critical, since the land is very very good at absorbing it. So yes, sometimes water does reflect radiation...
The problem for Global Warming Alarmists is that there is no way to test for such a thing.

The idea is that visible light hits the earth, and warms it up. Some of that light is reflected straight back, so it leaves the atmosphere the way it came in and we're done. A lot of that light, though, gets absorbed by trees or rocks or walruses, causing them to heat up. They'll slowly re-radiate it out again because of blackbody radiation (all things radiate continually, even the universe itself) but it will be in the form of lower energy, lower frequency wavelengths. This means that energy from visible light gets absorbed and often radiated back out again as infrared.
CO2 and other "greenhouse" gases let light in the visible part of the spectrum pass unimpeded, but they don't let IR through as easily. So, energy comes in but it can't get back out again.

That's more or less true, although one of the big arguments in the first half of the 20th century was that water vapour in the atmosphere completely masks the IR absorption spectra of CO2, and thus it doesn't matter how much CO2 you have in the atmosphere. It took until the 50s for scientists to realise that while this is fairly accurate (although not entirely) at sea level, it's most certainly not true in the upper atmosphere where (a) there's not much water vapour and (b) the absorption spectra don't ove

Svante Arrhenius "was the first to calculate on the heating of the Earth in 1903. But, he refers to Fourier, Pouillet and Tyndall as predecessors. He was the first person to predict that emissions of carbon dioxide from the burning of fossil fuels and other combustion processes would cause global warming. Arrhenius clearly believed that a warmer world would be a positive change. From that, the hot-house theory gained more attention. Nevertheless, until about 1960, most scientists dismissed the hot-house / greenhouse effect as implausible for the cause of ice ages as Milutin Milankovitch had presented a mechanism using orbital changes of the earth (Milankovitch cycles). Nowadays, the accepted explanation is that orbital forcing sets the timing for ice ages with CO2 acting as an essential amplifying feedback.
Arrhenius estimated that halving of CO2 would decrease temperatures by 4–5 C (Celsius) and a doubling of CO2 would cause a temperature rise of 5–6 C.[5] In his 1906 publication, Arrhenius adjusted the value downwards to 1.6 C (including water vapour feedback: 2.1 C). Recent (2007) estimates from IPCC say this value (the Climate sensitivity) is likely to be between 2 and 4.5 C. Arrhenius expected CO2 levels to rise at a rate given by emissions in his time. Since then, industrial carbon dioxide levels have risen at a much faster rate: Arrhenius expected CO2 doubling to take about 3000 years; it is now estimated in most scenarios to take about a century."
Some quotes:
"To a certain extent the temperature of the earth's surface, as we shall presently see, is conditioned by the properties of the atmosphere surrounding it, and particularly by the permeability of the latter for the rays of heat." (p46)
"That the atmospheric envelopes limit the heat losses from the planets had been suggested about 1800 by the great French physicist Fourier. His ideas were further developed afterwards by Pouillet and Tyndall. Their theory has been styled the hot-house theory, because they thought that the atmosphere acted after the manner of the glass panes of hot-houses." (p51)
"If the quantity of carbonic acid in the air should sink to one-half its present percentage, the temperature would fall by about 4; a diminution to one-quarter would reduce the temperature by 8. On the other hand, any doubling of the percentage of carbon dioxide in the air would raise the temperature of the earth's surface by 4; and if the carbon dioxide were increased fourfold, the temperature would rise by 8." (p53)
"Although the sea, by absorbing carbonic acid, acts as a regulator of huge capacity, which takes up about five-sixths of the produced carbonic acid, we yet recognize that the slight percentage of carbonic acid in the atmosphere may by the advances of industry be changed to a noticeable degree in the course of a few centuries." (p54)
"Since, now, warm ages have alternated with glacial periods, even after man appeared on the earth, we have to ask ourselves: Is it probable that we shall in the coming geological ages be visited by a new ice period that will drive us from our temperate countries into the hotter climates of Africa? There does not appear to be much ground for such an apprehension. The enormous combustion of coal by our industrial establishments suffices to increase the percentage of carbon dioxide in the air to a perceptible degree." (p61)
"We often hear lamentations that the coal stored up in the earth is wasted by the present generation without any thought of the future, and we are terrified by the awful destruction of life and property which has followed the volcanic eruptions of our days.

Or maybe it's like the Michael Moore thing, where lots of right-wing idiots (and trolls) thought everyone left of Mussolini worshiped Moore even though the reality of it was that we were slightly impressed by his documentaries but still had some issues with the movies as well as with Moore himself.

He was awarded the Nobel Peace Prize. If that's not putting somebody on a pedestal I don't know what is.

There as been numerous independent inquiries into this matter, and Phil Jones has been cleared in all cases. Guess *everybody* is in on the conspiracy, and only Steve McIntyre knows the "truth"
I wonder how easy it would be to assassinate your character by trolling through your emails. All we have to do is snip a sentence here and there, and then impugn your motives, and then the angry mob will take care of the rest.

It's true that by removing context you can make a lot of stuff appear bad. But it's equally true that if you see enough smoke, there might just be a fire.

I contest the word independent in the sentence above. We knew the result of these inquiries before it was published.
So you admit you (collective) knew he was innocent, and you made the stuff up to make it look like he wasn't. Thanks for the confirmation.

Starvation is just going to get worse if current trends continue. One of the real problems with climate change is that if things do heat up or winds do change their patterns, there's the potential for many people to be starving, many of whom aren't presently starving.
As for the size of the problem, it's not that big, the solutions are largely there, it's just that there isn't the political will to do it in places like the US and China. The technology to deal with it has largely been developed, it's just ver

This is insane, you cannot rationally be proposing that argument. Historical records have had the average temperature warmer than now, and the result was an INCREASE in arable land across the globe and growth of civilization as a result. War

That may be true in another world of the many-worlds multiverse. Not this one.
Not globally, not even for the Northern Hemisphere, not for any climatically meaningful interpretation of "now".
Really, people, this is not hard. Google for Spencer Weart, read his website, then google Skeptical Science and read John Cook's web site.

Climate has always changed, and we've always had to adapt in order to avoid starvation. To think that if we were to make energy so expensive that developing nations couldn't even afford to cook their food, that somehow we'll stop climate from ever changing again is kind of silly.
Until technology arrives that can beat natural petroleum products on affordability per kWh, moving to these more advanced technologies is a surefire recipe for increased world poverty. The rest of the world knows that.

It's already cheaper to drive your car on electricity. I've heard it said a gallon of gas equivalent amount of electricity us under $2. Now we just need better battery technology which is coming. Some coal plant proposals were recently abandoned when it became apparent that solar PV power will likely be cheaper than coal around 2020.
Re: (Score:2)
Okay, so here's the problem - "cheaper than coal" can mean either we've made coal more expensive, or that solar has become cheaper in absolute terms. While I'll agree the first is possible, the second is highly unlikely.

1 ton of coal costs $36 = $0.006 per KWH
$45,000 5KW solar energy system produces about 119,246 KWH of electric over its lifespan meaning the average cost equals $0.38 per KWH.
We're talking an order of magnitude

Static analyses are great fun, but they are misleading.
PV cells have been decreasing in cost at the rate of 22% per doubling of production capacity for three decades now. There are good reasons to think that this trend will continue. Since PV now provides less than 0.03% of global energy, there's plenty of room for ten more doublings. That gets us down to under ten percent of current PV costs.
