Global Warming Theories...?

Question

Which global warming theory do you believe to be true and why?

Answer 1

i have read about a theory that says solar activity matches the rise in temperature just as the rise in "greenhouse" gasses does. so which one is dominant? i think more work needs to go into it.

many people have very strong opinions about global warming, and i am not against going "green." there are many good reasons for going green. i am just not convinced that its going to save the world.

i also personally think anyone that states their argument and then says "anyone that disputes this is stupid" totally loses any credibility. that is another reason i question the effects of humans on global warming...everyone that supports the theory says "if you don't believe this then you are stupid." (just look at the answers on this topic)

Answer 2

To make a declarative statement that there "are no flaws" expresses a dramatic lack of scientific education and is a very poor reflection on the academic system. Where has the Socratic Method gone and why have so many schools stopped using it? For true science, almost nothing is without error. Even the theory of Gravity first put forward by Isaac Newton is being revised. In reality it is no where near as simple as Newton thought... You want some flaws, ok here they are: The hypothesis' and such are demonstrated through computer models only. No two models end with the same results. Most models can't even duplicate their own results twice. The theory is based on a postulated cascade effect. Most who talk about global warming either don't realize this or fail to point it out. There is NO empirical evidence to support said cascade effect. NASA recently released a study showing that there is significantly more longwave radiation (heat) escaping the earth that ANY computer models allow for given current concentrations of CO2 in teh atmosphere. This is physical PROOF that elements of the theory are flat wrong. Current global warming thoery as postulated by the IPCC has been demonstrated to have underestimated the effect of solar variablity by a minimum of a factor of 6. By definition this means that the IPCC overestimated the effects of greenhouse gases. There are MANY more, but alas I am at work and have to coach football for my son tonight so I'm out of time.

Answer 3

That it's mostly man made.

The reason why is that these theories work. They match the observed data.

Theories that it's natural don't work. They don't match the data. Which is why the vast majority of scientists agree that it's mostly man made.

"I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”

Vice Admiral Richard H. Truly, USN (Ret.)
Former NASA Administrator, Shuttle Astronaut and the first Commander of the Naval Space Command

"There's a better scientific consensus on this [climate change] than on any issue I know... Global warming is almost a no-brainer at this point. You really can't find intelligent, QUANTITATIVE arguments to make it go away."

Dr. Jerry Mahlman, NOAA

Answer 4

Global warming was discovered on Venus in the 70's. ! We found out that their atmosphere is mostly CO2 and their surface temp is hundreds of degrees. Not theory -FACT!
Now consider that man is emitting hundreds of millions of TONS of CO2 every year into our atmosphere which is as thin compared to the earth as an apple skin!

Answer 5

There were glaciers covering much of Europe and North America over 10,000 years ago, and the glaciers have been retreating ever since. They are still retreating. They may be retreating faster now because of all the CO2 we have put into the air, but they were going to do that eventually anyway.

Answer 6

There's only one theory. The GW contrarians have yet to offer up a viable alternative. They seem to think that saying, "It's a natural cycle," explains everything. In order to have a valid theory they need to provide evidence that carbon dioxide is not a greenhouse gas and does not drive the climate, and provide evidence of some presently active natural forcing that does.

Answer 7

the one that is based on scientific fact:

human activity increases greenhouse gas concentration which increases the greenhouse effect.

all others are based on scientific hypothesis, and many still in circulation have been shown to be false.

so to sum up, as of right now, by definition, there is only one global warming theory.

Answer 8

I believe the globe is warming and has been for hundreds of years. I believe it has warmed and cooled many times. I believe this warming period it is warming at a faster rate than previous times, but not sure how much and why.

Why? Because I am finding more and more valid questions about the data. Can't seem to get answers because the roar from the left is so loud no one can discuss anything anymore. I guess Al and Oprah said it so I need to sit down and shut up.

Answer 9

Global warming is cyclical and normal. Why? Previous ice ages have been reversed and the glaciers have retreated.

very confusing situation. check out on yahoo or google. that could help!
