What is really causing global warming?

Answer 1

Too high of a population.

Answer 2

The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and greenhouse gases. Climatologists agree that the earth has warmed recently. The detailed causes of this change remain an active field of research, but the scientific consensus identifies greenhouse gases as the primary cause of the recent warming. This conclusion can be controversial, especially outside the scientific community.

Adding carbon dioxide (CO2) or methane (CH4) to Earth's atmosphere, with no other changes, will make the planet's surface warmer; greenhouse gases create a natural greenhouse effect without which temperatures on Earth would be an estimated 30 °C (54 °F) lower, and the Earth uninhabitable. It is therefore not correct to say that there is a debate between those who "believe in" and "oppose" the theory that adding carbon dioxide or methane to the Earth's atmosphere will, absent any mitigating actions or effects, result in warmer surface temperatures on Earth. Rather, the debate is about what the net effect of the addition of carbon dioxide and methane will be, when allowing for compounding or mitigating factors.

Due to the thermal inertia of the earth's oceans and slow responses of other indirect effects, the Earth's current climate is not in equilibrium with the forcing imposed by increased greenhouse gases. Climate commitment studies indicate that, even if greenhouse gases were stabilized at present day levels, a further warming of perhaps 0.5 °C to 1.0 °C (0.9–1.8 °F) would still occur.

Answer 3

Most likely a periodic shift in solar activity. It's happened before, but recent cycles seem to be getting faster and more erratic - although that's probably an illusion caused by more accurate recent data.

According to the Discovery Channel - a vital source of scientific information if ever there was one - volcanic activity causes significant global cooling, so global warming may simply indicate a period of reduced volcanic activity. That is, unless they broadcast a 'strictly objective' special hosted by Ted Koppel; then it's caused by Republican policies.

Answer 4

Al Gore invented global warming after he invented the Internet.

Answer 5

THere is no way to know for sure.

P.S. to the above person. CO2 does NOT make the Ozone layer, thinner, moron. It's ironic that people claim that science proves that global warming is happening when they can't even get their facts straight.

Answer 6

Global Flatulence - animal, vegetable and mineral. Don't forget the earth has many active rectal areas in the form of volcano's and malignant parasitic infestations know as homo-erectus that can cause significant damage. Garbage in - garbage out!

Answer 7

Billions of cars spewing carbon monoxide while at the same time millions of acres of trees (that should be eating carbon dioxide and spewing out fresh oxygen) are being cut down and replaced with a few lil bitty new trees that can't carry the loads.

Sorry bout the run on sentence.

Answer 8

The sun, we just went through an Ice age, in 10000 years it'll be cold again.
Man accounts for less than 7% of CO2.

Answer 9

The sun is melting the polar ice caps which is causing the ocean level to rise and that's the reason why we are having so many severe hurricanes and strange weather!!!

Answer 10

we're causing carbon dioxide and cutting down all the trees which can't use all the carbon dioxode so the carbon dioxide is making the ozone layer thinner which is causing more sunlight and UV rays to enter into the earth! huh! all that in one sentence! I need to go back to english! lol! ;-)
(not if we all burn and die of skin cancer!)

Answer 11

All of the hot air coming out of the environmental activists mouths. Maybe if they would shut up it would cool off.
