Does global warming really exist, or was it made up to scare people into taking better care of the environment

Answer 1

Scientists agree almost 100% that global warming is occurring.
The popular media is divided on the question. Why the difference? The media in the United States is controlled by mega-corporations who don't care about anything but PROFIT, PROFIT, PROFIT.

Answer 2

The climate is probably changing but even that is hard to be certain of because we have so little data. A hundred years of data when more than half of it is suspect is hardly proof of anything in a system that takes tens of thousands of years to do anything. It is entirely possible that the slight warming we've seen is no more than a slight variation, nothing more. There are computer models that seem to indicate the globe is warming as the result of mankind' influence but the climate models themselves are unreliable and have even been shown to be dead wrong over huge areas of climate.

One of the most recent and important new studies is the antarctic core sampling they are doing. It demonstrates clearly that the global temperatures have been as much as 36 degrees higher numerous times in the last couple million years. In other words, it presents solid evidence that the global temperatures change radically on a normal cycle. It still does not prove or disprove mankind's influence but it is a good start towards learning what is really going on. Keep in mind that there is solid proof that cheetas, elephants and giraffes roamed northrn Europe thousands of years ago. The climate was such that creatures comfortable in today's equatoral climate were at home in Europe. That indicates a very much warmer world.

Another subject that they are studying in hopes of better understanding global climate change is the sun's fluctuations. The sun is not a steady source of heat. It gets hotter and cooler. How does that effect global climate? Still another is the build up of methane gases bubbling up from the seafloor and carbon dioxide from volcanos and earthquakes. How do they impact the climate? Methane is far better than carbon dioxide at retaining heat so this is probably important.

Lastly, a group of more than 200 scientists from Duke University are studying the fact that pollution obscures and reflects sunlight preventing it from warming land and sea. How does this impact the climate?

It is premature to claim we really know what is happening. Unfortunately, it is politically bad to openly voice opposition to the theory of global warming. I have noticed though that most major news sources have backed off the wild claims and are using the term climate change uinstead of global warming.

Answer 3

There is much serious science that would lead one to the conclusion that humans are contributing to the heating of the atmosphere by increasing the amount of "greenhouse gases" that trap heat here on earth. The models that scientists have built predict an increase of up to 5 degrees over the next century. There are certainly holes in all of these theories, and the models do not all predict the same degree of warming, but in general, it is pretty much settled in the scientific community.
Even if it were not settled science, the down-side risk that we could lose much of our low-lying land due to the ocean rising because of the melting of the polar ice, and that the weather patterns could become unstable, are significant enough that we need to start moving now to limit the extent of the damage without waiting to see what the absolute amount of the damage will be.

Answer 4

I believe it does exist. I think that governments have been holding back information because they don't want people to panic. Millions of people are living in areas that are going to increasingly be at risk from natural disasters. The economy is stronger when people are confident about the future. If you were a leader, would you want to create panic or slowly educate the masses so they have time to adjust to new ideas and dangers? I think we should try very very hard to slow down the cycle that has started. We should also help each other as much as possible. I hope the wealthy people (many have already been amazingly generous) will look at ways to help and invest in the future for our children.

Answer 5

Since global warming is an environmental problem, then the fact that we agree we need to take better care of the environment sort of says it is real.

Answer 6

Global warming is a very controversial subject.

It's my opinion that we should assume that it is a very real concern and we should be doing everything financially reasonable to try and clean up the environment.

The reason I say this is simple - if we are wrong, we have lost nothing and gained a cleaner environment - but if we are right and do nothing, future generations will be paying a dire price for our inaction.

Answer 7

it exists i bet if you went on google or yahoo or any search engine and typed in global warming tons of stuff would pop up such as what scientists are doing i have this article on it and i wish i could give it to you to read but all i can say is that it does and if we're not careful i don't wanna know what will happen but it will take a few more years before we can super truly worry

Answer 8

Actually, government favors the global warming theory. They stand to profit immensely from it just as they are profiting from "saving wetlands". If there is warming from CO2, it is not from burning fuel on the surface of the Earth!! Since CO2 is heavier than air.... maybe burning fuel above 30,000 ft is the source. Jet engines burn 2-5 tons of kerosene per hr.....each ton of fuel produces 3.66 tons of CO2...... thousands of hours of jet traffic daily above 30,000 ft..... Methane-- ozone degrades methane to CO2 and H2O... lightning produces ozone....The good news -- CO2 slowly drifts down to earth where plants take it up instantly.

Answer 9

If it actully did exist I don't care and nether should you because I will be dead by the time the enviorments detroyed, so why should I care. And I'm sick of you tree huggers.

Maybe THE SUN IS JUST GETTING WARMER!!!

Answer 10

It exists, even though 31% of us dont believe it. even though every single project done (except one) has pointed to yes.
Watch Al gores movie, its really good and its not exagerating
