Yeah, that's insane isn't it. Because small amounts of anything can't possibly be significant. You can't die from toxic doses as low as 0.000000001 grams per kilogram of body weight of botulinum toxin. :roll:
By the way, more than 30% of the carbon dioxide in the atmosphere now is from human sources. Natural sinks remove only about 57% of our emissions. An accounting of our combustion of fuel sources alone would be enough to raise the total atmospheric carbon dioxide by much more than the 39% it has gone up by, without natural sinks like the ocean absorbing it, and in the process acidifying.
But I don't don't bong. For me, the starting point of science is wrong and too limited in scope to be of much use to me. I find engineering more useful to physical reality but I also find physical realty too confining.I see you found the bong OK then...

I agree with the Beav in that the scientific community is stagnant at the upper echelons. True scientific inquiry is stifled by academics protecting their Nobel peace prizes.
we should both have long ago been boiled in a large vat of dark matter over an enormous dark energy hot plate, but for the fact that the keepers of st einsteins infernal flame are a sorry lot of posers singularly incapable of anything but endless appeals to authority.
Isn't it odd that our alleged fault is just the the same sort of inquiry demanded by the scientific method and natural curiosity and reason. Would they profit if their irrational ideas met no resistance at all?
i see you found the bong ok then...
We are not going to change the temperature of the ocean or modify the temperatures that hold or lose snow pack in the higher mountains. These things happen and change according to the dictates of nature and circumstance.
No, you were actually challenging the amount, and whether it could be significant. It is. The role of carbon in the atmosphere, specifically carbon dioxide and methane, is a well known and quantifiable physical mechanism. Even the crank who wrote the article doesn't ignore this fundamental piece of science.
So, because you like the outcome, you'll demonize scientific findings of it's consequences. This doesn't make you a heretic, it makes you a denier.
It rejects anything empirical that does not support it hypothesis, and therefor the scientific method.
No...this is actually what you are doing.
The evidence for anthropogenic influence is overwhelming. :
.
In fact these MODELS, which btw are not science, not in the sense of the scientific method hypothesis, experiment and empirical validation... have NEVER been able to predict everything.
This is a wonderful lecture!
The argument about how to treat climate change is good, but the best part is the first bit: lessons learned about heresy. Read that even if you can't stomach more gab on CC.

That's not correct. Four of the five major mass extinction events we know of from the geological record are associated with sharp increases in atmospheric carbon dioxide (not carbon, as you keep saying), which appear to be due to the appearance of huge flood basalts, which geologists for some inexplicable reason call traps. Lesser extinction events (we know of at least nine), are similarly associated with higher levels of greenhouse gases in the atmosphere, though not as high as for the major ones. Today's conditions are somewhat unusual, carbon dioxide levels have been relatively low, and in fact still are compared to much of the deep past, for all of human history, but they are rising relatively quickly in geological terms and the consequences can be devastating.They have never been able to link in the climate epochs of the past....
Wrong, wrong, wrong, and wrong. Surprise surprise.
Models are used in science all the time. No models are right, some are useful. I use disease models at work, and we can produce efficacious vaccines using these disease models.

Here's what happens, somewhat oversimplified: The planet warms over a relatively short period of time due to sudden increases in carbon dioxide and methane, usually caused by flood basalts. This disrupts ocean circulation, and in particular what are called the conveyor systems, like the Gulf Stream, which transport warm surface water to arctic latitudes and generate deeper returning cold currents. The bottom waters begin to have warm, low-oxygen water dumped into them. As warming continues, the temperature differential between high and low latitudes shrinks, and ocean currents and winds pretty much cease. The ocean becomes increasingly less well mixed, anoxic conditions rise to ever shallower depths, and when it gets to where light can penetrate we get a bloom of sulfur bacteria and a strong flux of hydrogen sulfide gas into the air. That breaks down the ozone layer, higher UV radiation kills off the oxygen-producing phytoplankton, and the overall combination of anoxic oceans, radiation, high heat, and hydrogen sulfide creates a massive die off in the seas and on land. That's a greenhouse extinction. The biggest one ever was at the end of the Permian 250 million years ago, associated with the Siberian Traps, in which something like 90% of species snuffed it. Atmospheric carbon dioxide levels at the time were about 3000 parts per million, over ten times today's level. The most recent one was the Paleocene thermal extinction about 50 million years ago, when levels were near 1000 parts per million. Every mass extinction known except the one that ended the Cretaceous 65 million years ago (that one was an asteroid strike) is associated with spikes in greenhouse gas levels in the atmosphere.
We're creating another one. The science is sound, and incontrovertible now. I suggest you dip into a couple of useful little books on the subject for the long term perspective: Under a Green Sky by Peter D. Ward, and Frozen Earth, by Doug McDougall.
You certainly cannot. The combined efficacy of any vaccine hovers around 1 per cent.
:roll:Vaccination against disease has never been demonstrated to be of any medical value whatever.

What, the catastrophist is denying the legitimate scientific evidence of a catastrophe? Generally I just ignore the stupid things you post, but there might be some help available for you. Richard Dawkins has a new science book out for children called The Magic of Reality: How We Know What's Really True. Buy it, read it, and if you can understand it (which I frankly don't have high hopes for), you might eventually come to understand enough to be worth taking seriously. Right now, you don't.Absolute drivel right from the first to last sentence. ... we certainly do not know that any asteroid caused any extinction event.
I don't know off the top of my head, but I'm sure you can find that datum as readily as I can.What is the percantage of GG created by man -
