Who believes in Global Warming and do you think its our fault?

Question

based on some evidence i have seen Global Warming has near nothing to do with humanity, rather the earth goes through documented cycles of temperture change.

Answer 1

The earth does indeed go through natural warming and cooling cycles - it's done this since it was created some 4.5 billion years ago.

The current natural warming phase has been ongoing now for 18,000 years and is the reason for the end of the last ice age. The natural increase in temperature is minute - about one thousandth of a degree per year.

The thing is, during recent decades the rate of increase has been much faster, faster than at any time in known history. It's currently 30 times as fast as would be expected. If this were a natural rate of increase then the world would have been lifeless for thousands of years and the temperature now would be so hot that lead would melt.

Since the start of the Industrial Revolution about 200 years ago the speed at which the world has warmed up has been dramatically increasing and there's a perfect correletion between the rate of temperature rise and the amount of CO2 in the air.

It's indisputable that mankind is contributing to global warming and to date NOT ONE SINGLE report has been produced that proves global warming to be a fallacy. In fact, of the almost 1000 reports produced EVERY SINGLE ONE concludes that global warming is happening.

Where there is dispute is in how much is natural and how much is down to human activities. There's also dispute about the amount the temperature will rise in the future and what the effects will be. However, as more and more is learned there is a general consensus begining to form as to what will happen in the future.

Answer 2

I 100% believe in global warming. There is too much evidence to say that it isn't happening. Over 100 scientist just conviened to answer this question and they believe they have within 99.9% certainty proven man is responsible for global warming. While their study says it's not a question of whether or not we've "ruined" the earth but when it will make life uninhabital.

I don't know if I'd fo that far, but looking at the way the weather has been in the last several years it is observable that the client of the earth has started to change since the industrial revolution. While the earth may not seem warmer, the real threat of global warming is the severity of the storms. While we may not see the number we have in past years, the storms we are getting are stronger and more powerful. Also research Alaska on the internet. Many towns that were once protected by the permafrost now need to be moved because the land is erroding right underneath them.

Answer 3

There is widespread agreement that climate change is being caused by human activity, although the jury is still out on this because as you say, there are documented cycles of quite wide-ranging temperature changes. The thing is, rather than saying that we need absolute proof that people are to blame I think we should take another approach.
1) If human activity is to blame for temperature rise, then we'd better do something about it or we'll cook.
2) Even if it isn't, we should look to renewable resources or energy and use our fossil fuel more efficiently - once it's gone, it's gone.

One thing to bear in mind is that most of the big arguments that have discounted human activity as a factor in Global Warming have been produced from oil companies or those in their pockets. We should consider whether this might be revealing a conflict of interests.

Answer 4

There is no global warming. Those who believe there is just look at one area. For example:While winters are warmer in some areas, they are colder in another. Also, they say that ice is melting in Antarctica. The LarsenB ice shelf is melting, while the west Antarctic ice shelf is thickening. Antarctica has been cooling since the 1960s. As you said, the earth does go through temperature changes every 100 years or so. Evidence has shown that the earth is warming, but everything is not going to suddenly melt and the humans, plants, and animals fry. =)

Hope that helped you.

Answer 5

I won't repeat the previous answers, and you've gotten some excellent answers.
However, I think that maybe there's some good in the current armegeddon talk about the global warming, and that's about finding alternative energy sources to fossil fuels.
If you think about it, all of mankind's advances for the past 100+ years was because of coal or petroleum: our personal transportation, most of our electricity, central heating, plastics and other modern materials are all based on fossil material that we've pulled up from the ground.
We're so accustomed to it that we take the stuff for granted. Even Greenpeace sails around in ships that are made from metals that required fantastic amounts of energy to forge and bob around in plastic, gasoline-powered Zodiacs.
This stuff isn't going to last forever, and whether it lasts another 100 years or whether we fry the planet long before that by using it all up, the truth is, we're going to have to find another way to get our energy eventually.
It's a monumental task to find a replacement for petroleum and coal, so we should get started on it now. If all this environmental scare lights a fire under us to get us off our petroleum habit, then why not? The end might justify the means, even if it turns out to be all bunk.

Answer 6

There is no "believe" inglobal warming or not-it is a scientific fact, well established. As is the cause--human activitties that release huge amounts of CO2 into the atmosphere.

There is no evidence to the contrary, any more than there is evidence that gravity, or electricity, or other phenomenae don't exist. Any "evidence" you think you've seen is faked.

Answer 7

I think that the earth is going through an overall warming trend that has nothing to do with us, but that we are making it worse. The warming of the planet doesn't scare me too much, earth's creatures are designed to adapt, but the depletion of ozone freaks me out.
Down with greenhouse gases!!

Answer 8

of course it is the fault of humans. Do you think animals by themselves would cause lead based particles to pollute the air; and deplete the ozone.

would there be PCBs in every water way and undergroune water table in the United States without humans?

would the ozone layer be almost nonexistent over Australia without humans?

The so-called "evidence" you have seen is made up lies aka junk science from people willing to lie for payment by organizations such as the Heritage Foundation; many of whom had about 1 year of high school science and then call themselves "scientists"

know your source, double check your source, and then check it again.

Answer 9

I do; I definately think that it is our fault. All the ice caps melting in Antarctica causing seals to die! Horrible! And all the polution that we give off and all the space we take up... that's got to do something... No wonder why the earths temperature is increasing every year.

Answer 10

I don't believe in global warming. Even some of the smartest scientists don't.
