Well, its been said so many time over and over, IPCC does no research. Hence, the arguments are really from done science by other ppl. And those arguments and contra-arguments is what this is all about and the point again is that there is something to most of them. The talk I was referring to...

bystender, the point is how to decouple human and natural influences. Hence, all the facts which you elucidate can be postulated to be caused by natural cycles. (And yes, there is strong evidence coming out to support it. Just yeasterday I attended talk by J. Burrows who has shown the complexity...

Ivan, you are begging the question...

Why so? Interesting is that all the information presented in the piece has been iterated on this very forum many times, except no thread expressing the slightest doubt on the spin of global warming came out. I wonder if we really need the illusion of authority which in this case is bunch of non...

It does not have to be or it could be. It has to do with the concept of impulse. That is proportional to the force and time interval over which it acts. So if for example one bend his knees during landing , hence extending the time over which the change in momentum takes place, hence reducing...

Exactly, and now its another form of political support, how unscientific. It purports already distorted "religious view of the topic" that researching otherwise and reporting results that do not support this hypothesis are somehow against science/planet/life/blahbalh. Plus the fact that Gore is...

Right, speed up by faster heat removal, i stand corrected. DaeSpam, sweat is cooling by evaporation, I was trying to see if object will cool below the air temperature just due to wind alone. (I don't think I am understanding the russ's comment on the steady state of frozen solid)

thanx for the input russ Thats exactly what I thought I said. 1st point:Are you implying that it is possible for anybody temperature to cool below the T of the air due to wind effects at certain conditions? 2nd: explain how that is not applicable in the beginning Thats exactly why I...

Well, quick back of envelope results given convection heat loss is 1/2 of radiative loss in wind from http://www.drphysics.com/convection/convection.html,where 1/3 of heat loss is due to convection without wind condition. I got something order of 1000 W , due to conduction, convectin...

I sure did, is it than reasonalbe to assume the windchill temperature rather than the air temperature in this example?

Now that I am thinking about it, is the wind actually relevant? The wind acts only to slow down the process of equilibriation between body and the air, by keeping theT gradient between the body and air by blowing off the near skin molecules of air that my body heated. The body, even in height...

Can we pose it as such? Im standing in the storm at T=220K (naked :D) and there is a wind blowing at 20 m/s. The ambient pressure is 1atm and assume Earth atmosphere with air weight 0.029kg/mol . Assume crossectional area of my body is 1m2, Cp (air capacity at 200K) = 1650 J/kg.K, Cp_body=...

Very sad and ludacris at the same time.

How can that be? In Antarctica the ambient air has temperature and hence radiates back to you. Space has no temperature, hence it should feel a lot worse ...? Assuming -80 C in storm conditions, you get back around 70 W m-2 from the air in radiation.

I am not sure what you mean by "effect of EF". Imagine lightning strike/discharge. The temperature in immediate vicinity of this discharge is more than 10,000 degrees which effectivelly creates plasma. Here the flow of e- can possibly dissociate or ionize O2. However, O2 just residing in E field...
