@hawkeye10,
Nobody is freaking out. Serious people are studying the phenomenon and trying to reduce emissions, and non-serious people and crooks are in denial mode. That's all.

@parados,
I dont suppose sequence means anything to a Performing Arts major...

I said "when no one claims the Antarctic ice sheet will melt but you mention it"

and you reply with "No one mentions it "

Is your mummy home ? Can she help you not look so stupid ?

Where is the science, parados . I see a distinct lack of your ability/willingness to discuss the science .

@hawkeye10,
Greens always freak out . It is part of their love of telling everyone what to do, that only they have special knowledge .

Humans currently spend more CO2 on warming themselves than cooling themselves . If the planet was hotter, we would save on CO2 emissions .

@Ionus,

16 is egregiously bad too. Greenhouse gases absorb the infrared radiation re-radiated after absorption by the earth. Some is re-emitted toward space. Some is re-radiated back earthward, which warms the troposphere and ultimately the earth and the oceans. No violation of trhe second law of thermodynamics.

Congratualtions, ionus, in your misguided grasp of science, you've just done a particularly poor job of trying to refute the greenhouse effect, which has been settled science for sevmore than a century, decades before the right totally goot climate change wrong.
Greenhouse gases, because of their molecular composition, react with INFRARED RADIASTION coming from the earth, whcih re-emitted the IR it got from the sun. Some is re-emitted earthward, some is re-emitted upward and escapes into space. The IR re-emitted earthward is what causes theheating of the earth and the atmosphere. Whatever you think you mean by "the air's ability to absorb heat may be impaired", that is in no way a description of the process. It bverges on sheer gibberish. I suggest you read the wikipedia article on the greenhouse effect, since you clearly have no grasp of what is happening.

@MontereyJack,
Heat ALWAYS, note that term ALWAYS, goes from hot to cold . If an object is hotter it can not take in heat from a colder source . This is important because the ability of the atmosphere to warm the earth (including the oceans) will only occur when we have warmer air . This means modelling must take into account accurate temperatures . At the moment we use the average of the minimum and maximum which is NOT a true reflection of what temperatures were experienced during the day .

Seeing you are particularly bad at ad hominems I feel it necessary to teach you about them too . Gee, if you are going to represent the science side of GW, I am going to have a really easy time . Would you mind in future if you put your comments outside the quotes for my comments ? I dont want anyone thinking I say some of the stupid things you say. and I especially dont want your opinions and lack of science riding on my coattails . I put you into the category of emotionally disturbed when it comes to discussing GW .

Since space is cold and the earth is warmer, by your argument we can't get any heat from the sun. An interesting argument, but rather idiotic on your part.

Have a guess here, paradum, which is hotter, the earth or the sun ? And sorry, there is a time limit of a month . Or do you think space interferes with radiation ?

@Ionus,
Radiation? You mean like Monterey Jack pointed out is what the atmosphere does and you emphatically told him heat only moves from hot to cold? Is that the radiation you are talking about?

I thought heat was a function of motion.

Am I wrong?

@Frank Apisa,
Yes . Heat is a function of atomic energy, specifically certain bands of radiation emitting from the electron levels .

@parados,
Yes, paradum, radiation is the mechanism for moving energy from hot to cold, as well as conduction and convection . Perhaps a brilliant Performing Artist like yourself can explain why you think the atmosphere behaves like a heat pump ? You will have to explain some science one day, I'm sure people dont want to hear your empty snide snickering based solely on your opinion . Where's da science, you comatose cretin ?

I'll say it again...heat only moves from hot to cold .

@Ionus,
Just want to be sure I understand (I may not be able to)...so I'll ask another question:

Is there a significant difference between an explanation of "heat"...and "heat transference?"

Heat itself, as I remember what little physics I studied, was the result of motion...absolute zero being that point where there is no motion at all.

Can there be heat without motion?


(I've tried looking this up in Wikipedia...but that seems to go all over the place.)

Really? Ages ago, when I was a school, that was called thermal energy, and heat was just the transfer of energy.

Thanks for the update, Ionus!

@Frank Apisa,
Its the other way around . Atomic motion, a vibration of an atom in this instance, generates heat . That heat in contact with another surface will vibrate the atoms in the other substance . That is conduction .

Gases react with heat by being pushed upward (away from gravity's pull) by cold pushing underneath and thus hot gases rise . The denser cold atoms have more attraction to the earth . That is convection .

Radiation is where the electron levels emit a certain band of radiation due to the agitation and vibration of the atom they are orbiting .

Heat is a measurable quality . Heat transference is measurable only by the heat of what it left compared to the heat of where and what it affected .

Absolute zero is where no atomic vibration (heat) exists .

Quote:

The motion you may mean is the atomic vibration that results from excess energy within a substance causing it to loosen its bonding with other similar atoms or those within a structure, perhaps crystalline in nature . This loosening takes a substance through the four stages of matter, solid, liquid, gas, plasma . Because of its uniqueness, it may be worth putting in absolute zero as a 5th state, but I dont think it has been achieved yet (very close though) .

Yes, Walt, but since then they have invented the steam engine .

Quote:
In thermodynamics, thermal energy refers to the internal energy present in a system by virtue of its temperature.


Quote:
In physics, heat is energy in transfer other than as work or by transfer of matter. When there is a suitable physical pathway, heat flows from a hotter body to a colder one. The transfer results in a net increase in entropy. The pathway can be direct, as in conduction and radiation, or indirect, as in convective circulation


I hope this helps with your schooling .

It's nearly 50 years ago that I got my Abitur. And since I got my university degrees even with that knowledge in physics - I've no intend to start school again.

Never too old to learn . When you give up, you die . I have read everything I could lay my hands on since a very young age . I wish I had of had computers then ! You have several degrees ?

That last sentence was a heat joke, right? Wink
