New idea for global warming

[ox1111]

I agree heat is heat on earth. It may be small but it all adds up to a hugh figure. Think of all the cars putting out billions of btu. millions of homes billions of btu etc...power plants, slash and burn farming. Road millions of miles of black roads. To say this has little effect in weather patterns is nuts. People say these are small and not important when in truth they are the largest causes of global warming. I'll prove it. No one would debate it is warmer in the city than the county land mass around the city. A city is not global but it is a large enough land mass you could not imagine heating. but there is no doubt it is warmer buy a sizable amount. now realize hundreds of cities doing the same thing. an increase in ice at the poles is a definite sine of warming. The warmer the air the more humidity it has to freeze. The very coldest parts of earth accumulate very little ice due to very dry air.

Its because we are using energy, and a lot of times, that energy gets turned into heat. Be it the coal burning, cars running, or my computer generating heat, its all adding up and warming up the earth. Its not cooling off because the heat doesn't have anywhere to go. You've gotta have a trasmission medium to move heat. So it can't leave into outer space.

Silly idea?

Heat can radiate just fine with no medium. Yes the heat from your car or computer eventually radiates off into space. The biggest cause of global warming isn't the amount of heat being generated or hitting the earth. It's the amount that is failing to radiate because greenhouse gases absorb the radiated energy.

The amount of heat hitting or being generated on earth is of little relevance to the amount being kept. Just look at Mercury vs Venus. One is almost on the sun surface but the other is far hotter.

omg another global warming thread

what is the big deal i don't feel any warmer (probably due to ac)

well actually global warming has helped us if you look at a long enough timeline.....10,000 years ago we came out of an ice age, and if you look at global temperatures for 100,000 years you will see a very specific trend in temperatures of hot and cold, we should of started a cooling trend about the industrial age, but the actual temperature now is significantly higher if you look at the cycle. just my 2 cents.



this talks about what i am saying, but i read somewhere else about the cooling trend over a long timeline.

woo-hoo, someone else agrees with me.

And I never said CO2 had NOTHING to do with global warming. Just that all the heat that we generate (cars, factories, blacktop roads, etc) would contribute to GW.
