Really when my ground floor furnace is on the second floor of my house is usually warmer than the ground floor. Why??? Convection. I love it when warmmongers talk thermo. Its so funny.
You are right. The heat itself does not travel from cold to hot but hotter gas and liquid molecules always travel up taking the heat with them. This process is called convection.
Even funnier when deniers try to talk science. Your furnace moves heat by forced air or water (with a net input of energy). Convection only works in the presence of a temperature gradient. And hey, guess what? Convection carries heat from warm places to cool places. Funny how those natural laws work: they're laws.
The cult is the GW propagandists that have no credibility or integrity. Going green is a failure http://nation.foxnews.com/wind-energy/2012/04/17/wind-industry-has-lost-10000-jobs-under-obama http://www.detroitnews.com/article/...tough-sell?odyssey=tab|topnews|text|FRONTPAGE
That's right. Hot water has more energetic molecules so in a given space, there are fewer molecules in hot water then in cold water, making it lighter so it moves upward creating convection currents. Funny how those natural laws work.
Thats funny you must have scoured the internet for that one convection always works regardless of if its artificially forced. It is just slower. When you dont have forced air gravity provides the forcing just slower. At the point where the convection reaches a barrier(the roof on of the second floor) the air stratifies and the upper layer is warmer than the layer below it. Your theory would only work if my house had an infinitely high ceiling. Like I said you warmmongers are so funny. This isn't the first time you have forgotten the importance of stratification in an argument with me.
I just showed my brother who is a HVAC guy what Poor Debater said and he found it very funny. To get my goat he said "That idiot must be an engineer." I'm like "No engineers aren't that dumb. He must be a research scientist."
In a house when heat rises it is because of natural convection. You do not want that to happen, for this reason some houses have the ducts in the cieling to push the hot air back down, but you can just always turn on your ceiling fan to push it down instead of converting all your ducts. -It is a good way to save energy and do you part in stopping greenhouse gasses.
No it doesn't always work. Convection cannot work in thermal equilibrium. As I said before, there must be a temperature gradient for convection to work, and convection always moves heat from a warm place to a cool place. And neither you nor your HVAC brother has provided a single example of the universe not working according to the laws of thermodynamics. But if you can do so, a Nobel Prize awaits. And the heat source is where? And the complete temperature profile from floor to ceiling looks like what? And the heat moves in which direction? Where do we have a cold place getting colder? In the first place, it's not my theory, it's Lord Kelvin's. And in the second place, it doesn't matter how high or low the ceiling is: heat does not move from a cooler place to a warmer place without a net input of energy. Period. This isn't the first time you've suspended the laws of physics to claim that Windigo is righter that the rightest scientists who ever lived, either. Hubris.
He is right that thermal kenetic energy does not flow from cold to hot places, but regardless of that fact the molecules themselves that viberate less (cold) move down with gravity and the molecules that viberate more (hot) move up against gravity. When the hot molecules move upward they retain some of their heat and so when they are blocked by the ceileing they collect and the ceiling gets hotter than the floor. This is the very force that drives the winds and ocean currents. It is also a major factor in how the earth cools. Without convection our Earth would be much hotter than it is today.
Something that won't be covered by the AGW community. Gas escaping from ocean floor may drive global warming
You are so funny you dont even get it. One would have thought that I simplified it enough for you to get the concept of how a house heats from the top down but I guess that would entail admitting you are wrong. We know you can never do that. Yes you are kind of right. Convention doesn't move heat. Heat is radiation. Convection moves molecules. Colder air is denser air warmer air is thinner air. Gravity and pressure force the cold air down and the warm air up. That is convection. In an infinitely open system every layer will be colder than the layer below it. That however doesn't happen in a house because a house isn't an infinitely open system. On the first floor. Try and keep up genius. Increasing temperature with height. Up. Hot air rises. Did you sleep through class as a kid. But the room heats from the top down. No part of the house is getting colder. Furnace is heating the entire system with the heat rising fastest at the ceiling. Lord Kelvin would be laughing at you right now. It doesn't have to for the second floor to be warmer than the ground floor. You still don't understand the concept of stratification. I dont suspend the laws of physics I just know them a lot more completely than you do.
not quite...in a home with forced air heating the most efficient place to put heating ducts is in the ceiling yes ...but that isn't done to force air down there isn't enough air pressure to do that efficiently...it isn't done often for several other reasons, expense, practicality, complexity of install and appearance (it doesn't look good having all those ducts in a ceiling when they're less obscure on the floor) and in colder climates placing ducts in the floor below the windows is more efficient at helping keep windows ice free... What brings the warm air to the floor efficiently is cooler air leaving the room via the cold air returns at floor level, the firing of furnace draws in the air...
well, that leaves me stunned I can hardly believe that came from you...absolutely correct...if you were to be very technical there is no such thing as cold, just degrees of heat...cold is a human bias...
What? The SAME methane caltrates that are starting to emit methane as the world warms from CO2?? The ones that are implicated as a major concern for a "tipping point" for runaway greenhouse gas effect? THOSE methane caltrates? http://www.giss.nasa.gov/research/features/200409_methane/ http://www.realclimate.org/index.php/archives/2005/12/methane-hydrates-and-global-warming/ Once again we are back to trigger mechanisms - the methane will not be a problem if the global temperature does not get too high

how did I not catch that, well done Bower...imagine his embarrassment that he now supports the CC scenario that all those "warmists" have been warning about...
as Bower pointed out this has long been known as a consequence of global warming whatever the cause of warming...which is why AGW is a concern, driving the warming toward a tipping point of no return...
Evidently you missed the point. The theory is that this is what put us into the interglacial. Someone here keeps asking how natural warming could happen. How do you think any of this could be triggered in the first place to take us out of the glacial period? Hmmmm?
But those caltrates did not decide all by themselves to suddenly melt and add methane to the atmosphere did they? There had to be a trigger that warmed the planet to the point where the methane was released Something like ooooh! LET me see, maybe an orbital variation? Precession? Solar cycle? Any of those happening at the moment?
a mistake is a mistake. an outright lie, like the fabrications deliberately produced by the denier lobby, is something quite different.
