Global warming: science and pseudo science [modified]
-
OK, here is my take on global warming. I dont know anything about the science, or the computer models, or so on but; A volcano spews out a hell of a lot of CO2, dust, SO2 and god knows what else. Volcanos happen every 5 years or so, so it is complete crap to talk about nature being non poluting. It was also a lot warmer before 1500 or so. Viking settlements in Greenland, Romans growing grapes in the north of England, all attest to that. The world, if we are to believe the scientists, millions of years ago, was a festering, methane and CO2 swamp, with volcanos erruoting and so on. ie, uninhabitable. And it stabilised. To what we have today. The system balanced itself. So tell me, can the human race really throw such a stable system off course? A system that can and has coped with such extreme conditions? I think not. And I think the temperature rise we are seeing is perfectly normal, and only taking us back to where we were in the time of the Romans. Nunc est bibendum

A post a couple of days ago pointed out that man-made CO2 emissions are 150 times greater than volcanic emissions. Look it up for yourself. This psuedo-argument that volcanos cause more global warming than humans must be put to bed once and for all. It is not true.

I dont know the figures for volcano vs human being, anyone out there got any? Re the viking settlements in greenland. They were there, but it got just too cold in the 15th century for them to survice. And the Romand were growing grapes in the north of England.

I think that is not true at all. The medium temperatur of the earth was less at that time. Global warming doesn't mean that temperatur is getting hotter in england, in fact it cause a temperatur reduction there (like in Germany) because of the decrease / loss of gulfstream.
So you are stating that the reason we cant grow grapes in the north of england is because of the gulf stream being deflected? But the temperasture fell in the 15th century! That is when the Viking colonies failed! Long before any supposed impact mankind could have had.

Of course. Human can
Why? Why 'of course'. You take it as a matter of fact that we can. Where is your proof? Nunc est bibendum

The cooling period that drove the Vikings from Greenland was "The Little Ice Age". And unusually cool period probably caused by reduced solar activity. To make it worse, it followed an unusually warm period. The Little Ice Age didn't end until the mid 19th century. The evolution of the human genome is too important to be left to chance.

This is still just theory and here you are stating confidently that europe will get colder because of global warming!
I don't think that's disputed. That fact is that it could - all it would take would be for the gulf stream to stop (or reverse, which would be even worse I'd expect). Climate is a chaotic syustem, and therefore by its very nature exceptionally hard to model. Given that and the vested interests on all sides it should be no surprise that there is no general agreement on what is (or is not) happening and why (or why not). What I do know is that chaotic systems can change without warning given a nudge which appears insignificant. Given that, I personally believe it's in our interest to ensure we disturb the environment as little as humanely possible. That's plainly not the case right now - quite frankly we are a bunch of irresponsible little brats when it comes to the integrity of our environment. Earth is, after all, the only planet we inhabit at the moment. If we screw it up right now we as a species won't get a second chance. :rose: Anna :rose: Currently working mostly on: Visual Lint :cool: Anna's Place | Tears and Laughter "Be yourself - not what others think you should be" - Marcia Graesch "Anna's just a sexy-looking lesbian tart" - A friend, trying to wind me up.

One thing that bothers me quite a lot is that politicians ignore a very simple truth. Regardless whether the earth is warming up or not, we let toxic stuff into nature. That stuff will eventually find its way into ourselves. There should be some kind of pressure on corporations to make them spend parts of their profit to research cleaner and safer options. If we don't die drowning in molten polar ice, we'll die in our own filth. :sigh:

I dont have a problem with what you are saying there! Quite agree, all the pesticides, dioxins, heavy metals etc are really screwing up nature, and will, one day, screw us up more than a few billion tons of CO2. Nunc est bibendum

That remains to be seen I think. Ultimately, we need a what-if-machine. :rolleyes:

There's just no happy middle ground for you, ha?
Middle ground is a Marxist concept!

Ah, OK, it was the term 'biosphere', I havent heard of it used to mean just plain old green plants. However, excess CO2 can be absorbed very very quickly resulting in increased plany growth. If anyone doubts me then I have absoloute proof: A friend of mine grew some big bud in his spare room using hydroponics. He used a CO2 bottle to increase the CO" in their 'biosphere' to increase the growth of the plants. Nunc est bibendum

I mean, can you actually see yourself saying something like, "I don't know anything about electricity, but this is why there's no problem with the wiring in your house..." - F
Would you expect me to comment on the accuracy of the computer models given that I have no knowledge of them at all? I am just drawing a conclusion based on known facts; that the earth was a lot warmer when the romans were in britain and when the viking colonies in greenland were viable. And that there was also an iceage that ended 10 thousand years ago. ie, that the earth is capable of large changes on its own. All of which happened without mans intervention. Do you have such a reverence for 'scientists' that you do not dispute everything they say? Do you not have a brain of your own that you use to make up you own mind or do you always do what your 'betters' tell you? You are a bit weak in the head if you do. Nunc est bibendum

Of course. Everybody understands that the climate changes naturally over time.

That's baloney. Life has been on the planet for about 1/2 billion years, not a few million.

No, it's not stable; it's dynamic. Our global climate system is in a state that sientis refer to as "chaordic" - that is, right on the edge of order and chaos. (This is sometimes refered to as a "metastable" state.) A "stable" system is one in which all the water is either frozen or liquid (for example) - we don't want that.

Err, I stated 'millions of years ago' ie, plural, many. I didnt state how many, so 500 thousand million is still millions. Idiot.

Yep, you have to be american to use a word like that. Tell me, is this the latest tredny word in weather science?

So you either: 1) KNow all about the science and models. 2) Dont know about them either, but dont have enough of a brain to form an opinion based on what you do know. 3) Are just an arse hole. Go on, let us know which one. Nunc est bibendum

I would reasonably expect you to inform yourself on basic climate theory and the existing evidence for climate change before expressing an opinion on the subject. Otherwise, you're just playing at science, flaunting ignorance as if it were a badge of honor (like every other pseudoscientist), and your ideas don't deserve the merest regard. - F

Why, it is only theory. I am confining myself to known facts. 1) The fact is we came out of an ice age 10000 years ago. 2) The fact it was a lot warmer for a long period of time a few hundred years ago. 3) The fact that increased CO2 in the atmosphere leads to increased plant growth. ie, it is absorbed.

Are you now! We had thermometers around 10,000 years ago, huh? And you've directly counted every plant on earth when CO2 and only CO2 has changed to validate the "fact" that CO2 increases plant growth? News flash: you're selectively assembling these "facts" of yours from a wider base of scientific knowledge - and using them to draw specious conclusions - which is either intellectually dishonest or deliberately ignorant. You would know which one better than me.
