Is global warming a myth or reality?

Question

Fact remains that nothing has been established scientifically about the catostrophic effect of industrial pollution and emission of
co2 on earth notwithstanding widespread fears the theories have created are these false alarms?

Answer 1

Reality!
Face facts!!

Answer 2

Read this and decide for yourself... 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

There is a cycle that earth does through.

There is also a slight shift that occurs in the polar position due to wobble of kind, and a slight change(shift) in the tilt.

Presently we are in warming cycle, in 60's scientist were worried about, cooling and blaming particulate pollution from chimneys and autos. To -day it is green house gases, at the last meeting some even were proposing more particulate pollution so two can balance each other.

We need to have good handle on it, by all means conserve, all resources, we know they are finite, we really do not know any thing for sure, every thing is an educated guess work on our part.

Answer 4

The fact of the matter is that the world average temperature is rising and global warming is real.

However, there are fanatics that are convinced this is caused by human activity. They use this as scare tactics that will eventually lead to taxation or other anti-market policies and regulations.

There are others that believe that the Earth has experienced at least 10 cycles over 50 million years of history. One report I read indicated the estimated temperature rise was 37 degrees and there was melting ice on both polar ice caps. I had this reference article bookmarked but it has since become obsolete.

Answer 5

“CapNemo” likes to go to all the global warming questions and paste in a statement pooh-poohing the threat. His statement is misleading and incorrect.

He says it’s only increased by 1 degree (F) in 125 years. This is a misleading number, because it is a global average: land and sea. We don’t live in the middle of the ocean and that’s not where the polar ice caps are melting. The temperature change over land surfaces has been twice that, and most of it in the last 40 years.

He says, “The average temperature in Antarctica is 109 degrees below zero.” If you go to his source, it says, “Temperatures reach a minimum of between -80 °C and -90 °C (-112 °F and -130 °F) in the interior in winter and reach a maximum of between +5 °C and +15 °C (41 °F and 59 °F) near the coast in summer.” OK, now the observation that the caps are melting makes more sense. It melts at the coast, in the summer, DUH! (Note by the way that his average number (-109) is only 3 degrees lower than one of the minimum numbers. I wonder, what kind of math did he learn?)

Then he says, “Back in the '70s all the hype was about global COOLING”. All what hype? I was around then. I don’t remember any hype. And if you go to his source, it says, “This theory gained temporary popular attention due to press reporting … The theory never had strong scientific support”. He tries to mislead us, by implying that a temporary flurry pf press reporting is comparable to what we are seeing now and that some hype without scientific basis is somehow similar to a consensus within the scientific community about global warming.

The truth is that those 2 degrees are HUGE in the scale of average weather change. But the real problem is the speed of change and that it's accelerating. Scientists are predicting a temp 4 to 8 degree (F) increase over the next 75 years. “This may not sound like a great deal, but just a fraction of a degree can have huge implications on the climate, with very noticeable consequences." (http://www.channel4.com/science/microsites/U/ukweather2080/5_predicting.html ). Yes, scientists predict, that's their job. They've gone to school years more than we have and spent their lives studying this stuff. This representrs humanity’s BEST GUESS at where this is all going. Of course, you can believe it snows in hell, or any other stupid thing you want. No one can stop you from believing what you'd rather hear, than what is the most probable outcome.

The link between CO2 and global warming is undisputed at this time. The amount of CO2 in the atmosphere has increased by more than 50% over the last 115 years (250 to 381 ppm, http://awesomenature.tribe.net/thread/fcc70c8b-be7e-489b-85f7-6c6c08031c65 ). In the last 30 years, it increased at a rate 30 times faster than at any period during the last 800,000 years. In other words, this change is totally unprecedented. (http://awesomenature.tribe.net/thread/fcc70c8b-be7e-489b-85f7-6c6c08031c65 ). What else is totally unprecedented about the last 115 years? Industrialization and the population explosion. Duh. This is not rocket science; it is simple arithmetic!

"If Bert Drake is right, the good news is that, within the foreseeable future, Maine residents will be able to stop banking their foundations and to store their down parkas and snow blowers in the barn permanently. The bad news is that a lot of those barns will be underwater" (http://awesomenature.tribe.net/thread/fcc70c8b-be7e-489b-85f7-6c6c08031c65 ). Yes, this is opinion. Who is Bert Drake? He's an SERC researcher who's been studying this for 17 years. If we aren’t going to believe our scientists, who then shall we believe??? Oh, I know. Let's believe CapNemo!!!

If global warming wasn't a real threat, why have 178 nations ratified the Kyoto Protocol to limit CO2 emissions? Why are the US and Australia the only two holdouts among the industrialized nations? (http://environment.about.com/od/kyotoprotocol/i/kyotoprotocol_2.htm )

CapNemo’s statement reminds me about the frog in the pot on the stove that doesn’t move as the water gradually gets hotter and hotter. From this seemingly insignificant 2 degree change, we’ve already seen enormous consequences. (http://www.davidsuzuki.org/Climate_Change/Impacts/) How much hotter does it have to get for some people to wake up and face the music? And in the meantime, while you’re pondering all of this, be sure to check the dates on people’s references. Things are changing so rapidly that older information is no longer useful.

Answer 6

The overwhelming majority of scientists agree that industrial pollution is impacting the rate of the warming of the earth but there it is disputed how much of an impact there is.

There are a few crackpots that claim it is a myth but just like the people that claim to be Jesus there aren't that many and few people take them seriously.

Answer 7

I'm no scientist but you can see the weather changing rapidly. In the UK we had a very late winter as it didn't arrive until early december and it normally comes in september/october. Now we are having gale force winds.

Something is going on with the environment and I think CO2 emissions are the reason.

Answer 8

I wonder if some people learnt reading

Global temperature is higher. Call it global warming,climate change or whatever you prefer. A few years ago some scientists rejected this statement, but today, they would be embarrased if they repeat it. Today, no scientist rejects that fact.

What some people (very few of them are scientists) still reject is that humans can reverse its effects.

Answer 9

Oh, it is a reality as scientific report after another declares and anecdotal evidence demonstrates. Unfortunately the world's bureaucracies are slow to react, and, if there was ever a doomsday scenario that I ever believed in, it is this one.

Answer 10

of course its real. due to excess carbon dioxide which floats close to the earth is causing the ozone layer to depleat. the polar ice caps melt and all the snow becomes water. soon the whole earth may sink in the immense amount of water

Answer 11

global warming may not take much time to turn from myth to reality if steps are not taken immediately.....govt's globally are working together in this regard and meets such rio summit.......kyoto protocol.etc ...which intend to cut down on green house gases emmissions and protect the ozone layer etc are steps in this directions..but will long time in yielding results............perhaps that's why u might consider it to be a myth.......
