I question even the experts on the problem of global warming.?

Question

All over the world we have been shown the results of a number of ice-ages that have disappeared because of global warming. what caused the global warming back then? I doubt if it was caused by humans in any shape or form. Scaremongering is raisng its ugly head and we are starting to give it too much credence.

Answer 1

You're a smart man Donald. Yes the earth gets warmer and colder all by itself and what we do is only a small effect. Don't believe agenda driven leftists who are insisting that the sky is falling. It isn't.

Answer 2

Its a little of both really. The Earth does follow a cyclical pattern of when we are in a perihelion verses aphelion rotation. That is, the distance we are away from the sun changes and so does the amount of radiation that reaches the surface of the Earth to warm it up. On average there is an ice age once every 100,000 years, though smaller ones are considered as well. The issue is the rate at which this is all occurring as we have no history to predict such a steep rise in some gases and a large drop in others.
So there is a grain of truth to this scare considering the greater amount of radiation that is reaching the earth's surface and the raising level of greenhouse gases which trap heat (radiation's result) in our atmosphere. The ones that are absorbing higher amounts of heat/radiation are methane (raised due to farming/agriculture (cow's and multiple stomachs) and rice patty fields), CO2 (technology(modernization), particularly current 1st and 2nd world countries that do no have the capacity or benefit of environmentally friendly methods or modernization), and water vapor. Though CFCs and O3 and Nitrous Oxide do too, we cannot limit them in the same fashion and degree (considering we are already short on O3, Nitrous Oxide and CFCs are usually limited (especially CFC usage). soo ya ^.^
The point is yes, its has been blown somewhat out of proportions, but the world doesn't move at any less than catastrophic and though it is expected, we are over the expected norm and not by a small margin. Let's put it this way, about 1% more oxygen in our atmosphere and the Earth would simply burn. . . . we are treading on thin ground and its not like there is any one system that can cause this change at once on an international scale. It will be a slow process, so why not start now? Don't get me wrong, the scare annoys the hell outta me, but people are stupidly wasteful as well. I don't mean the whole, never use your car, reuse clothes to the point of rags bit, but gluttony isn't something many countries like the US are short of right now. (like the 30 bedroom mansions . .. why do you need all the lights on when no one may enter a room for months??)

Answer 3

You're right; global climate change ended the ice ages as the earth warmed up again. The problem is that this took thousands of years, rather than only thirty to fifty years -- they're not saying that humanity is the ONLY reason the climate is warming up, but that we're contributing to it on a scale that the world has never seen before. If you look at Antarctic ice cores for atmospheric carbon levels or at the geological record for average biomass indications, you can see that these changes happened much more gradually as a result of natural phenomena, but when you add industrial pollution to the equation, you get a much higher consumption of organic matter.

Do we know for certain that global warming is happening? Scientists believe we do. Will it be as bad as some predict? We don't know, but if someone told you that based on current research that doing something, say eating McDonald's hamburgers and fries every single day of your life, would pose a 75% risk of dying young of heart disease or other health issues related to fat and cholesterol intake, would you:
a) just say, "well, they're not 100% certain I'll die of a heart attack, because there's a 25% chance they're wrong," or
b) eat a salad every now and then?

Statisticians say that one out of every eight households will experience a robbery this year. That's 12.5%, decent odds but not overwhelming. So the odds are actually pretty good that I WON'T be burgled... but I'm still going to lock my doors and windows when I'm not home. Common sense says that you should take reasonable measures against a possible threat, rather than only preparing for those you know will happen with 100% certainty.

If the data we have on hand at the moment says that we could all drown when the sea level rises a hundred feet, because we burn too many fossil fuels, even if it turns out they were wrong, wouldn't it be better to fail conservatively and try to clean up our act anyway? If you have a cleaner-burning automobile that gets better milage, it just means that you personally spend less money per mile for gas. If you come up with alternative energy sources for generating electricity, it means you have less dependance on foreign-supplied oil, and therefore are less affected by global oil supplies and the fickle nature of the suppliers. If you do what you can to conserve energy at home by insulating your home, getting more efficient heating, and turning off lights and appliances when not in use, you save money on your power bills. So the question really comes down to why NOT try to reduce your carbon footprint?

Whether we like it or not, we are part of the environment. What we do affects everything else, and it is our responsibility to take care of our home. If you insist on ignoring the problem and calling it simple scaremongering, rather than addressing the issue, I just hope you're a good swimmer.

Answer 4

99+% of all scientists disagree with you. They may disagree on some of the details, but not on the basic message. Global warming is real, it's not natural, it's caused by us. And it is a serious threat to our country.

Here's some solid information about the basic scientific agreement on global warming and just a little of the data underlying it.

Not from some weirdos, but from the most respected scientific organizations in the world. Practically every scientific organization publicly supports the reality of global warming.

The people below are hardly fans of Al Gore. They don't get their information from "An Inconvenient Truth", they get it from the very best scientists in the world. None of these people are fools, or environmental crazies. You may not respect them all, but surely you respect some.

"The science of global warming is clear. We know enough to act now. We must act now."

James Rogers, CEO of Charlotte-based Duke Energy.

"The overwhelming majority of atmospheric scientists around the world and our own National Academy of Sciences are in essential agreement on the facts of global warming and the significant contribution of human activity to that trend."

Russell E. Train, Republican, former environmental official under Presidents Nixon and Ford

"We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over."

Arnold Schwarzenegger, Republican, Governor, California

"Our nation has both an obligation and self-interest in facing head-on the serious environmental, economic and national security threat posed by global warming."

John McCain, Republican, Senator, Arizona

"These technologies will help us become better stewards of the environment - and they will help us to confront the serious challenge of global climate change."

President George Bush

Answer 5

Current global warming scaremongering is not about environmentalism, but rather about economics. More precisely, the economics of nanny state socialism. So-called manmade global warming is nothing more than a way to damage the US economy and promote the economy of China (and to a lesser extent, India).

Answer 6

You're absolutely right about global warming cycles in the far distant past, even before man walked the Earth. However, the current natural cycle is undoubtedly being accelerated and its effects heightened by our civilization.

Answer 7

You should be on the internet! :-))))

Answer 8

Thank you!!!!
