Tell me why global warming isn't real.?

Answer 1

To answer the above people.

Climate scientists know all about natural changes and causes of warming. They've gathered the data and studied it.

And 99% of climate scientists agree that man is causing climate change that is unnatural, rapid, and large enough to be a very dangerous problem for our modern society with high tech agriculture and a lot of people living in coastal areas.

Some of the stuff above is just flat wrong. One example. The increase in CO2 hasn't been steady, it's been rapidly accelerating. There's good data and everyone agrees about that.

Answer 2

Actually the temperature of the earth has increased less than 7/10 of 1 degree (C) from 1880 to 2005. That is an increase of about 1 degree (F) in 125 years. You may choose to believe that is global warming or you may not. Source: http://data.giss.nasa.gov/gistemp/2005/2005cal_fig1.gif There are numerous charts all over the internet showing the same. Some say that 1 degree is enough to impact the global climate, others say it's not. Most proponents of global warming think the earth's temperature has risen much more than that and don't even know that it has only risen by 1 degree. But the charts do not lie as do the proponents on both sides of this issue. The average temperature in the Antarctica is 109 degrees below zero. Source: http://en.wikipedia.org/wiki/Antarctica#Climate It seems to me 108 below (one degree warmer) is still pretty cold and not enough to melt anything. But there are those that say it will.

Back in the '70s all the hype was about global COOLING and another ice age was coming. I remember that they blamed pollution for that too. They said that all the pollution was darkening the skies and not as much sun was coming through so the earth was cooling off. It took many years to discover that they were mistaken and it was all just hype. Source: http://en.wikipedia.org/wiki/Global_cooling So when someone says, "the sky is falling" don't believe everything you hear on either side of the issue. There are Spin Doctors galore out there.

Most of the time people will form an opinion and not really be informed about the subject with which they become so opinionated about. So it's best that you not form your opinions from other's opinions, (as in this forum) but on the facts presented. (Many do not provide any proof or links to prove their point, just their opinion.) With that said we do have a responsibility to do our part by doing whatever is within your power to keep our planet alive and well.

I hope that helps...

Answer 3

That's an excellent and very controversial question. First and foremost, no one can tell you with any validity that global warming isn't real. Period.
Opinions do not constitute facts unless they are proved. And if "expert" opinions were truly "expert", there wouldn't be two expert sides debating this concern.
There are simply two major sides to this debate.
Al Gore says the northern ice packs are melting, and his opponents say, while that's true, why does he not mention that the southern ice packs are actually increasing in size? Evidence of past climate cycles, when mankind certainly wasn't a contributing factor, are also often pointed out.
In my opinion, it seems rather naive to think that mankind can spew millions of tons of CO and CO2 into our atmosphere annually and not have some kind of effect on our environment. I think all economically practical efforts should be implemented to help clean up the air - if we're wrong, we will have gained a cleaner environment - but, if we're right, we will have saved future generations from a potential disaster.
It's a win-win situation to try and keep the earth suitable for sustaining all living creatures in the best environment possible.

Answer 4

I don't think there's an accurate answer to your question. I'm convinced that global warming is all too real, simply because of the weather patterns where I live. We are well into winter now, yet we haven't had any winter temperatures at all, not even once, and more than half the days of this winter have been spent enduring heat that is higher than average for even summertime. Butterflies in the USA are migrating further north now than ever before, and our poor "love bugs" are so confused that not only are they out and about 2 months earlier than normal, they are also not mating (typically they fly around attached together). Small things are becoming more apparent, our flowers on certain trees are in bloom, when they should be looking half dead around this time. Bees are nesting in the walls of homes which usually happens around spring, and the mosquitoes haven't gone away for the winter yet. Ice caps are melting, coast lines are moving further inland.

I'm not sure of the causes of the earth's warming trend, and I'm sure no one can pinpoint humans as being the cause...but look at some of the facts...we put blacktops on our roads which attracks heat, and during all of the warming trends in history, there have not been any black top roads. There are more people moving around, more motion on the earth period, and motion creates heat. So, whether the warming trend is a natural event, caused by chemicals being released into the atmosphere, or just a cause of our habits as humans, no one can really tell...maybe it's just a combination of all of those things put together...causing the warming trend to be more extreme now than in history.

Answer 5

Global warming, at least over the past 150 years is real, and no serious person who is aware of the facts can say otherwise.

The extent to which this warming is caused by human activities such as burning fossil fuels is subject to considerable debate, however. The primary challenges to the theory that it is are as follows:

To Bob below, I didn't say it was steady, I said it was monotonic to different things.

1) Global temperatures as infered from ice core deuturium levels have gone through a number of warming cooling cycles in the past. All but the last of these cycles occured before the industrial revolution and thus, cannot be attributed to the burning of fossil fuels. The most recent warming cycle does not appear to be different than past cycles thus, it could be completely natural.

2) While it is true that the post industrial revolution levels of CO2 in the atmosphere have shown an increase to levels well above the highest seen in pre-industrial times (approximately 30% higher in fact), the current warmest temperatures are still well below pre-industrial (and in this case pre-historical) maximums by approximately 3 deg C.

3) Post industrial revolution CO2 levels have shown a monotonic increase from pre-industrial maximums to the current level. Post industrial revolution temperatures, however, have not. In fact, the post-industrial revolution temperature trend has shown a period of mild cooling, followed by a warming trend followed by a period of stable to slightly lower temperatures, followed by the current warming (which began in about 1980).

4) The post industrial revolution warming trend began approximately 100 years after the post industrial revolution increase in CO2.

To answer Bob's comment below: I did not say the increase in CO2 was steady, I said it was monotonic a totally different thing. I agree that the increase is accelerating.

Answer 6

It is real, but it is more a natural cycle of the earth's warming and cooling than an effect of human intervention. We can see that the average temp in the world is going up. But we also know that Ice ages have come and gone in the past and warm periods have come and gone in the past. We just don't have enough information to conclude that human interference has any effect on the climate change on Earth.

Answer 7

It is real, but we're not causing it, the planet does it on it's own. What we are doing is poisoning and polluting the tiny area of the earth we can actually survive in and believe me it is tiny. Ultimately our actions will make it impossible for us to survive on any part of the planet. The planet will get over it, it's coped with much more destructive forces than us, we won't.

Answer 8

If CO2 had increased as much as the environmentalist want u to believe about 30% many peoples that live in low places would be dead. CO2 will smother u.

Answer 9

It's happening here....
