Global warming. A different perspective?

Question

Could it be possible that most global warming is not produced by carbon emmisions but rather caused by man made heat

I mean my fridge, car, computer, boiler etc all produce vast amounts of heat, far greater than what would be found naturally in my area and theres 60 million people in my country doing the same thing. it makes sense to me that its the heat produced and not the emmisions that would cause the most rapid rise in global temperature (I'm not denying that carbon emmisions do some damage) your opinions?

Answer 1

global warming is just a joke, made by people who got bored crying over the rain forest.

Answer 2

The term 'Urban Heat Island' is used to describe the effect you mention. We produce heat in our homes, cars, offices, factories etc through a variery of processes. The greater the concentration of these heat producing processed the greater the urban heat island effect. Put simply, the larger a town or city is the warmer it is than the surrounding countryside.

London for example is usually 3 or 4°C warmer than the surrounding less populated counties. The same effect happens to a lesser extent in the UK's other large cities. There are many other factors that contibute to the Urban Heat Island Effect as well - both natural and manmade.

As others have said, the amount of heat we produce is very small compared to the heat we receive from the sun. At ground level alone it's less than one thousandth of the heat received from the sun.

Another important factor is that it's not the heat produced which is the problem but that it's being retained within the atmosphere. If there were no greenhouse gases surrounding Earth we could all light massive bonfires and burn the planet to a crisp and every bit of heat would escape into space in a matter of hours. The warming is being caused by increases in the atmospheric concentrations of the greenhouse gases - they act as a barrier and prevent heat escaping into space.

Answer 3

Not in any shape or form am I not admitting that I am contributing to carbon emissions.

But why are planes still allowed to fly at 32 - 35,000 feet and are NOT included in the emission equation?
After all carbon is a heavy gas so how can my exhaust gases get to the ozone layer?

OK heat rises but not that far up in the air because it gets colder the higher you go.
Don't believe me? Try going up in a hot air balloon.
Don't forget your flying jacket and a thick pullover.

Americans and Russians are sending rockets up through the ozone layer almost every month. Think of the amount of burning fuel gases given off and staying in the upper atmosphere.

They have a lot to answer for long before I will put my hands up.

Answer 4

The problems under dialogue, regarding world warming are: - Is international warming a outcomes of human pastime or traditional changes in the solar radiation. - What precisely is the Mechanism that motives global warming. - how a lot warming is to be anticipated. - what's going to be the consequences of worldwide warming on the polar ice caps, permafrost lands and ice on mountains. - what is going to be the consequences of world warming on sea phases. - what's going to be the results of global warming on climate, including exchange in tropical storms patterns, precipitation distribution world large and ocean flows of bloodless and warm water. - what will be the effects on the ecology, species so as to emerge as endangered from climate change. - what will be the worldwide harm and bills

Answer 5

I see where you are coming from, but compared with the energy from the sun that hits the earth constantly the heat your appliances produce is miniscule.

It is the accumulation of CO2 that has made the atmosphere into an insulation blanket. Energy from the sun can still come in, but the heat can't escape as easily as it should.

Answer 6

That's all part of the equation. It takes energy to run those appliances and make those appliances. This energy comes from fossil fuel burning facilities. Obviously their emissions contribute to smog and other airborne pollutants. But things like aborbed heat from the sun cannot be discounted either. Asphalt roads not only off-gas petroleum vapors but also absorb sunlight and generate heat. In the winter, what used to be vast mirrors of reflective snow has become mottled with pockets of heat retentive asphalt, such as roadways, parking lots, and shingled rooftops.

Answer 7

Cosmic rays reaching eartgs atmosphere cause big low clouds. When the sun is active with solar storms, the storms prevent the cosmic rays from reaching our atmosphere, which means little cloud coverage and loads of sun. When the sun is calm loads of cosmic rays reach our atmosphere and create major cloud. The tops of the clouds are bright white which reflects the suns heat back into space and we cool.

Answer 8

Actually, the emissions it has creates more heat than heat it gives off. How would you scientifically explain that? "Oh, well the heat that fridges and cars give off is the reason it's so hot." Carbon dioxide controls temperature, too much=hot, to little=cold.

Answer 9

no, ghg's trap far more energy than the heat coming off appliances and engines, but these things contribute to the "urban heat island".

Inbound sunlight is short wavelength and doesn't get absorbed by molecules in the atmosphere. Molecules on the ground absorb this light and heat up, as they cool they emit longer wavelength light, which greenhouse gases do absorb, so this energy gets trapped.

Answer 10

I have also been thinking of the same thing. The rooms were the most electic is used is always the hottest room in the house.

Answer 11

I believe it is a combination of both abuses on our part. We are a selffish generation. We are leaving much damage to our earth that will have to be repaired by the generation after our grand children.
