Do you Believe in Global Warming?

Question

Some people do, some people don't. Do you?

Do you believe? And if so, do you believe it is caused by human caused CO2 emmissions?

Answer 1

Well it would be stubborn to admit that we as humans have no effect on the environment. Admittingly the O3 [ozone] layer that protects us from a lot of the suns UV radiation is thinning, and the world is changing from our impact.

It could eventually become a problem to where we have to worry about it but its nothing that people should get all crazy over now, there's no point in that. Yes preventative steps should be taken so we can enjoy our habitat longer and for the future of our species, but ignoring the problem won't fix it.

Answer 2

Yes, I do believe in global warming, but I do not think the climate changes we are seeing are a reult of pollutant-caused global warming. I believe history tells us they are just natural climatic fluxuations. If you look back over the past few 1000 years you can see that. While I believe human industry and activity can and has had an activity on the environment, I don't buy that it is behind the current climate changes. If, however, we don't clean up our act soon, we MAY start to see some negative effects on the climate from the way we treat the environment, though my primary concern would be quality of breathable air and the hole in the o-zone layer, not artificial global warming.

We need to deal with the problems caused by pollution, but we also need to be intellectually honest about everything that is going on, and not idiotically politicize the earth's climate. Pointing blame at each other for the recent hurricanes etc; is as goofy as when 1000 years ago they blamed the black plague on witches and cats. My how the human race has grown.

Answer 3

I do believe in global warming, and I do believe that it has an effect on biodiversity, and I also believe that humans aren't doing anything to help it. But if humans are causing it, then why is the Ozone Hole over Antarctica? It has been shown that CFCs come from melting ice and glaciers. By that theory, it's a self-perpetuating cycle. I believe that if humans left well enough alone, UV radiation wouldn't matter so much to biodiversity: there would still be enough species to fill important niches if a few went extinct. Thanks to deforestation, pollution, overhunting, overfishing, etc. several important species have already gone extinct. We must also remember that DMS (dimethylsulfide) comes from sea spray and helps to cool the earth when it ends up in the atmosphere. CO2 comes mainly from volcanoes and other siesmic activity, and only a fraction of it comes from human causes. Global warming will continue long after humans are gone, in cycles as it has in the past. Mother Nature will be happy once humans are gone. There is also an indication of a 40 million-year extinction cycle for most species. Humans are pretty close to the end of their time, on the geological time scale. I think global warming is too hyped up and is used as a red herring to distract from real political problems. Deforestation and urbanization are bigger problems than global warming. By the way, water vapor is a greenhouse gas. If we're going to put limits on CO2 emissions, we might as well put limits on evaporation while we're at it, right?

Answer 4

Yes, global warming is a fact. I guess your question is whether or not it is man made. I think it is both. I agree that the Earth has periods of warming and cooling. What worries me is that the current warming trend is faster and has lasted longer than ever before. Considering that in the only the last 100 years have we managed to dump large amounts of greenhouse gases never before introduced to the atmosphere in such great quantities and that simultaneously we have destroyed as much 20% of the Amazon rain forest (those big trees in the Amazon produce 20% of the oxygen for the world not to mention removing CO2, a greenhouse gas) Of course, the Amazon is not the only place that is suffering from deforestation. I don't understand how people can say that won't affect the environment?

Answer 5

Yes and people in Denver believe in global freezing. Its not fiction its a proven fact that Global Warming is real.

Answer 6

Yes, i definitely believe in global warming

Answer 7

No. I don't "believe" in the Global Warming theory. It has yet to be proven global warming is man made.

Mr. Al Gore's movie left out these facts:
1) 6,000 years ago, the earth was hotter than it is today. 6,000 years is less than a second when compared with the age of the earth.

2) Temperatures dropped in the 1950's and 1990's when CO2 levels were increasing.

3) 140,000 years ago the earth had record CO2 levels and there were no gasoline powered cars.

4) 20,000 years ago, Canada was one big ice cube and half of the U.S. was covered with Ice. The grand canyon was formed by melting ice ages over 20 million years.

5) The temperature of the Earth has only increased by 0.65 of a degree in the last 110 years. There were faster increases in temperatures around 10,000 years ago and there were no gasoline powered cars during that time

6) The theory has not been scientifically proven. Scientists who disagreed with the theory were not invited to contribute to Al Gore's movie nor were they invited to the conference about global warming.

7) NASA has said that great temperature changes are normal. Just 10,000 years ago, the earth warmed up extremely in less than 20 years. There were not many people around at that time.
NASA:
"Rapid changes between ice ages and warm periods (called interglacials) are recorded in the Greenland ice sheet. Occurring over ONE OR TWO DECADES, the warming of the Earth at the end of the last ice age " http://earthobservatory.nasa.gov/Study/Paleoclimatology_Evidence/Images/gisp2_temperature.gif

9)NASA scientific data has shown most of the changes of temperature are due to changes in the Sun. Mars, Jupiter, Saturn, and Pluto all have global warming right now.

Answer 8

I suggest this service: http://www.goobypls.com/r/rd.asp?gid=538

It's a cheap service that works great! It could be used for a much deeper search. You can use it to get hold of different varieties of background reports, and in addition cell numbers, addresses and names.. you can get unlimited reports... I ran with this because I required to verify more numbers. You can get the name, other phone number, address history, relatives, and much more about anyone! The completly free reverse phone lookup generally doesn't provide anything interesting. To get interesting information, money will must be paid. The free searches don't provide considerably more than what may be found through the phone directory or personal information and they simply require your email to send spam. The reverse phone detective search tool does work, but you should use just the service that I posted above. The last thing you want to do, is pay for a service and find the numbers you want to lookup are not available in their directory.

The service that I reccomend doesn't have any kind of problem , you won't get any bad surprise! Trust it!

Answer 9

Global Warming is a phenominon. The earth goes through hot cycles and cold cycles. We happen to be in a hot cycle. Humans are a cause for many environmental problems we definatly emit to much pollution. Now green house gases are not frequently emitted by humans. We do emit them but they are also emitted by things we can not control. Farm animals like cows, pigs, horses and other livestock actually produce large numbers of green house gases. There are other things to. I could get into a very large paper here but as your question asks it is up to each person. There is a lot of research that can be done. I think there are bigger environmental issues that need to be adressed rather then everyone flipping out about global warming.

Answer 10

The temperature has raised 0.7 degrees Celsius in the last 100 years. It has fluctuated up and down in 30 year intervals. During the early part of the 1970's, "scientists" were suggesting that we put coal soot on the north pole in order to keep the earth warm, all this to prevent another "Ice Age" they said that we were headed for.

In short, I believe that the earth is getting warmer. I don't believe that it is caused by man. I believe it is natural. Scientists are also saying that the sun is burning hotter than usual too. Might that have something to do with this phenomenon??
