Who Believes Global Warming is just a theory?

Question

In response to An Inconvenient Truth, Gore faces the challenge of proving myth versus fact. National Geographic.com asked scientists to affirm many of the films' assertions. They found he underscored the devastation, and only disagree on when distaster will happen. Who among us does not believe in Global warming?

There is a direct correlation between human-caused co2 and warming. By burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising. "How much" is natural versus manmade is of no matter, we will still experience horrible consequences

At last! A panel of top climate scientists told lawmakers that the Earth is running a fever and that "human activities are responsible for much of the recent warming." Their 155-page report said average global surface temperatures in the Northern Hemisphere rose about 1 degree during the 20th century. http://www.cnn.com/2006/TECH/science/06/22/global.warming.ap/index.html

Americans it seems, simply don't want to take responsiblity for their actions.

Answer 1

Global warming is happening, make no mistake about it. This natural cycle that we're going through seems to be accelerating. Is it due to humans? Quite possibly. Can we do anything about it? Maybe, but will it have a dramatic effect? Who knows.
Nobody in their right mind believes we are going to "destroy" the planet. At worst we'll just make it uninhabitable.

Answer 2

Yes increased CO2 will warm the earths atmosphere, but what about the "Carbon Sink" of the oceans. In the earths geologic past when global temperatures were seen to rise, and Ice was all but non-existent, even in Antarctica, at a time when its relative position was still over the South Pole. Biologic activity in the oceans increase and massive Limestone and Dolostone deposits are the result. The amount of Carbon locked up in these types of rocks is huge, several orders higher than all the fossil fuel (Oil, Coal, Etc) materials ever created and or burned.

Than mankind has induces all this "Warming" is foolish. We give ourselves too much credit that we can outclass the Sun and various orbital variations of the Earth as the main cause of atmospheric warming. There are far too many variables in Atmospheric dynamics, both known and unknown variables, to lump them all together in a few computer models. The models which fit the outcome desired are used and instantly grab media attention, while the models which show cooling, or other than desired results are put on the back shelf of academia since they have no WOW factor for the media and the agenda of many in the human induced Global Warming debate. There is simply too much political capital and media dollars to risk to have things any other way.

Answer 3

The presence or absence of a warming trend in the last 100 years or so is not at issue. What is at issue is the cause. Their is no definitive proof that human activity has anything to do with it.

The past several million years of Earth history have been characterized by 100,000 year periods of ice age punctuated by warmer 10,000 year interglacial periods.

We are now 10,500 years into the latest interglacial period. We were going back into an ice age in the not too distant future anyway; so it is just as likely that this warming trend (if unusual and caused by humanity) will result in a beneficial reduction glaciation.

It is also possible that we are seeing a normal cyclical upswing in temperatures that are the immediate precursor to an oncoming ice age.

The bottom line is that the only thing that science knows for certain is that they don't know what is going to happen and why. Spending the entire world industrial output to solve a problem when we don't have any idea of the outcome either way seems rather foolish.

Answer 4

If the earth temp changes then yes it does I have seen cool and warm times in my life. But does man do this I would say no.

Why do I say this.

Just how much of the "Greenhouse Effect" is caused by human activity?

It is about 0.28%, if water vapor is taken into account-- about 5.53%, if not.

This point is so crucial to the debate over global warming that how water vapor is or isn't factored into an analysis of Earth's greenhouse gases makes the difference between describing a significant human contribution to the greenhouse effect, or a negligible one.

This also must be in play. If we were cooler after a big Volcano then.

Global cooling and ozone depletion
Measurements from recent eruptions such as Mount St. Helens, Washington (1980), El Chichon, Mexico (1982), and Mount Pinatubo, Philippines (1991), clearly show the importance of sulfur aerosols in modifying climate, warming the stratosphere, and cooling the troposphere. Research has also shown that the liquid drops of sulfuric acid promote the destruction of the Earth's ozone layer.

Answer 5

The fact of global warming is obvious to anyone who looks at it honestly. Fixing this will be the greatest challenge of our lifetimes.

It's terrible that we are doing so little now, but that's how it is - fixing the problem will take sacrifice, so some people refuse to acknowledge the problem until it's just too obvious to ignore.

Conservatives push fake science and bald-faced lies as fact the same way the tobacco lobby defended smoking. (For instance, "global warming is cyclical and natural." Any scientist could refute that in a second - there is a cyclical component, but we're heating up faster than we ever have over the last several thousand years.)

Their goal is to delay the inevitable as long as possible; nothing else matters.

Answer 6

Wrong question. Global warming is a demonstrable fact. The CAUSE of global warming is completely up in the air. The earth has been as warm as Antarctica being a tropical location to as cold as glaciers covering much of North America, and not only once. Query whether this is anything beyond another natural warming trend.

THAT is the issue. I tried to find the answer and couldn't. From all the hype, I assumed it would be easy to find a direct link between the warming we are experiencing and humanly manufactured greenhouse gasses. That was not the case. If you have a link on point (not just showing that the globe is warming, which is obvious), please share.

Answer 7

National Geographic is a communist organization and the science is pretty clear on the fact that global warming is impossible.

For example, during the last ice age, the amount of carbon dioxide was ten times what it is now. Hardly evidence that global warming happens at all.

But the most telling thing about the theory is that the changes in environment due to mankind are very very small when compared to natural changes in environment. Even with dramatic changes, climate is unaffected.

If our environmental impact is small and large environmental changes don't effect climeate, where does that leave global warming?

It leaves it as junk science.

Answer 8

300 years ago they grew grapes in England and produced wine.

Greenland once 700 years ago really was green.

Iceland once was a land of ice.

The Earth cooled and warmed and cooled again. The Earth is now warming again. It is still not as warm as it was then.
Inspite of this people survived quite well during these periods. In fact they flurished.
Historians know this.
The Sun did it and is doing it again and has done it for millions of years. In fact before the beginning of time the Sun has been warming and cooling.

However to say so would mean the loss of hundreds of jobs of Professors in Universities across the country who study the last 30 years of Global temps over and over again. Professors who work 5 hours a week, 8 months a year at 100 thousand dollar salaries. It would also mean the loss of jobs of thousands of assistants, associates, Politicians, and political groups who depend on Global Warming for a living.

Answer 9

Why do I have doubts? Well back 15 years ago my science class was being taught about how the earth was cooling and we'll all be frozen in ice unless we do something about human pollution. Well that didn't work so now the anti-human league decided to switch theories and go with warming. And sure enough some desperate politicos jumped on the band wagon.

Is the earth warming up? Yes, will it cool down again sure will. Will we be around to see it, who knows?

Answer 10

Earth and Mars are experienceing "global warming" and it has negligibly little to do with anthropogenic CO2. There is nothing that can be done about dreaded "global warming". Al Gore's movie is a well-crafted political tool to frighten people into voting liberal. Unfortunately there are a lot of ignorant people with voter's cards that will not be able to separate reality and common sense from propaganda, false and biased science, distortions and Al Gore.

The "tipping point" is in 10 years? What a joke! Let's see, hmmm, that is just enough time to vote a liberal into office in 2008 and they must serve 2 terms (To save the World of course). If we don't vote an environmentalist liberal into office We Will All DIE! Bu ha ha ha ha ha!

If you would like the actual truth about "global warming" follow the links I have provided and have a nice bright and shiny warm day.

Answer 11

One cannot argue against global warming. The facts that polar and glacial ice is melting in indisputable. The real question is why? There have been ice ages and ice recessions since the beginning of time. The spot I know sit was under 10 miles of ice less than 15,000 years ago. Perhaps what Gore is harping about is nothing more than a natural warming period that humans and our pollution had nothing to do with. It's pretty egotistical to think we could destroy in less than 150 years(when the industrial revolution started) what it took God 7 days to create!!!
