I think you'll find most of the influx is from the Atlantic end. The point is that during this summer more than 1 million sq km extra ice has melted than in previous summers that we have comparable records for, that requires a lot of heat and has allowed more heat to be absorbed by being open for so long. Consequently the freezing season is likely to get off to a slow start and making a follow up melt next year more likely. If that is so a couple of more years would see a dramatic reduction in the September sea ice.

Of course, which is likely the reason both sides of Greenland have ice free land, isn't in within the Arctic Circle? >The >point is that during this summer more than 1 million sq km extra ice >has melted than in previous summers that we have comparable records >for, that requires a lot of heat and has allowed more heat to be >absorbed by being open for so long. That sounds impressive, but readers should not form an opinion without knowing the total area of Arctic ice remains all summer. If it is less than a million square kilometers, then it is something to consider, if it is 40 or 50 million square kilometers, then maybe it is a cyclic thing. >Consequently the freezing season >is likely to get off to a slow start and making a follow up melt next >year more likely.

I think I remember years when the entire coast of the Arctic Ocean was frozen year round, and then there are stories of being able to go by ship all the way from England to Alaska. I think a lot of shipping depends on being able to navigate a good portion of the coastline. But something as extreme as turning down thermostats in winter needs more background information than a number like one million square kilometers without a comparison number of remaining ice. To form thick ice, what is needed is glaze ice on the surface and then lots of snow, which can happen any time, so there is more involved than just the one time gain in BTUs.

This is the clearest it's been, guys like Amundsen took two years to get through, they'd be frozen in and have to wait for it to open up in 6 months time. This month it's been wide open all the way through. http://earthobservatory.nasa.gov/NaturalHazards/shownh.php3?img_id=14479 > > But something as extreme as turning down thermostats > in winter needs more background information than a number > like one million square kilometers without a comparison number > of remaining ice. > > To form thick ice, what is needed is glaze ice on the > surface and then lots of snow, which can happen any time, > so there is more involved than just the one time gain in BTUs. Most of Arctic sea ice is formed from freezing sea water rather than precip I believe.

Thats how Pirani vacuum gages work.- Hide quoted text - > > - Show quoted text - If you see that the kinetic motions of the molecules can transfer the energy to the metal so that the metal radiates as it does, let's look at higher temperatures. At 1000K, RT = 8315 Joules 3/2 RT = 12472 Joules Stefan Boltzman = 56,700 Joules per second per sq meter The frequency of highest intenstity of the radiation is 2.892um,, or .428 eV kT is equal to .0864eV or a photon of 14.345um So the mean kinetic energy if considered as 3/2 kT is .1296 eV If the gas within the duct is maintained at 1000K, it will bring the temperature of the metal plate to this temperature at which time it will radiate at these specifics. This rate of radiation is enough to radiate the energy of 1 mole of monatomic gas, (3/2 RT) in .21 seconds. So you are saying that the kinetic energy of the molecules which has an average equal to a photon of 14um is transfering energy to the metal to produce the photons of greatest intensity at 2.898 um. And that this quantity of gas with this average kinetic energy of the molecules is capable of producing the 56,700 Joules per second per meter? Should we go to higher temperatures? O2 and N2 can easily be heated to higher temperatures in which they radiate in the visible. So now we place the gas in a metal container with a glass window. Only rarified gases radiate in the specific intervals of spectra. All gases under pressure emit the same continous spectra through the visible frequencies. So at a little higher temperature, intensity maximum will be clearly in the visible, while average kinetic energy of the molecules is still in the infrared. This means that when a molecule collides when at average velocity, if it loses ALL of it's energy into a photon, this will still be 4.95 times less than the energy of highest intensity photons. How do the oxygen and nitrogen gas molecules attain the energy in which they are clearly radiating in the continous spectra in the visible, if they are not absorbing this energy in the infrared? The light leaving through the window is a quantity of energy. This loss of energy to the system, the loss of the heat through the rest of the container cannot be from the velocities and collisions of the molecules. The rate of replacement of this energy from the heat source through the gas to the molecules that are losing their energy to the environment cannot be quantified without the concept of the radiation field. The energy that is transfered through the gas to the metal is of this radiation field and is radiated as packets of energy from the electron membranes or oscillator of the molecules. KD

Anyone with any education or you would think, people interested in climatology, should know this. But we only get the twits with their false and pretended concern who only enjoy the thought of controlling other peoples lives and ignore the FACTS OF CLIMATOLOGY. If you want to change the fact of the ice caps melting, you should do something about it. Buy a big air conditioner and go blow it on the ice or something. Instead of sitting around and whining that other people should modify their modern existence. Even if CO2 caused warming, you have no program of reducing US emissions in any way which will affect concentration increases in the air. This fact can be roundly proved. The simple fact that China and India's growth will completely overshadow any reductions that we could possibly make is only one. China overtook the US in 2006 with a 10% increase 1 yr. At this rate, they will emit 2 times US CO2 in 10 yrs. No evironmental effects whatsoever from complete elimination of US input. So your attempt to promote the passage of laws to stop the ice from melting is an attempt to commit fraud. In the meantime, enjoy the euphoria of your delusions and obsession with your HOLY WAR against society which has no valid basis in climatology. KDeatherage CO2Phobia is a psychological disease. Seek professional help, buy an air conditioner and hire a criminal defense attorney. |
