Global warming,the great big lie.?

Question

If the history of the planet were the size of the Empire State Building,the time man has existed would only reach the size of a postage stamp.
So how can emmisions from the last 20-30 years threaten to bring the whole lot down.
How can people believe in this rubbish??

Answer 1

how can you people like you be so ignorant and foolish???

Answer 2

It's not the emissions of the last 20-30 years that they are worrying about but the build up of emissions since the industrial revolution over 150 years ago. According to the "experts" because of the world's over population and use of fossil fuels etc., the last 20-30 years has just made an already serious situation a lot worse much faster than they thought it would happen so that if the situation worsens exponentially over the next 20-30 years then the world REALLY will be in a lot of trouble.

Answer 3

How can technology from only 20 or thirty years make it possible to land on the moon? I guess it must not have happened.

The evidence in the scientific community isn't conclusive, but it sure is consistent. It's pretty simple math (and a little chemistry). We are injecting the atmosphere with enormous amounts of carbon dioxide, more than have even been released in one continuous interval. The effects are predictable.

Let's say you were in a desert climate. We could call it "California." For all of the place's history it was hot, arid, and marginal. Now let's say you invent a way to get water there. We could call that "irrigation." You add huge amounts of water to the desert, along with a lot of alluvium and fertilizers, and- voila!- the desert becomes some of the most productive farmland in the world.

Global warming is no different. Human technology makes things happen, and fast. Some things are good, some bad, almost all are both.

By the way, it isn't terribly important but the overall temperatures have been going up for about 100 years, not 30.
Peace.

Answer 4

yes humans have been here a fraction of the life of the planet, but in that time we have destroyed a considerable proportion of the planet leading to warming. Why do people find it so hard to believe that we cannot keep pumping out CO2 and CH4 (methane) without any affect on the planet. The question is not if the planet is warming, but how fast is it warming.

plus the industial revolution was further back than "20-30" years ago. and the earth has seen major chages occur such as ice ages and the complete shut down of the ocean flows

Answer 5

Scientists don't do hype and propaganda. GOVERNMENTS DO!

Scientists give the information to the people who can do something about it - namely the government - and they do with it what they will. They either act on it or they don't. If they choose not to act, the only way they can get the public behind them on this decision is deny that it is real. Yell "Hoax". Spend millions on government campaigns to discredit the findings. Make the public believe it isn't happening.

It's the SCIENTISTS that are saying we need to take action. It's the POLITICIANS that are yelling hoax (and a very small minority of under-achieved academics in the government's pocket).
Who are you going to believe, the professor whose studied this for 25 years, whose done extensive research, whose collected results from around the globe, who has had to convince a global committee of other academics about the evidence - or the politican who wants to save himself some money?

Yes global climate change has happened throughout Earth's history, but more pollutants have been released by man in the last 20-30 years than in the rest of Earth's history combined! It's unprecendented! Of course what we do effects the Earth. How could it not?

No matter how insiginificant you claim man to be, if we wanted to we could destroy this planet in 5 minutes. And when your children have to move out of parts of North America because of they've become uninhabitable, you'll remember the 'hype'

Answer 6

How is the length of time before something starts to happen relevant? Creatures have changed the atmosphere before, putting out "too much" oxygen. Too much CO2, aside from trapping heat, is also dangerous.
At the current rate of increase (~50ppm over 50 years), it would reach dangerous levels (5000 ppm) in about 4600 years, still a short time in history. If the temperature goes up 1 degree every 100 years, the seas will boil in about 15,000 years. Not to predict doomsday, just to show changes can happen in short periods, geologically speaking. Fossil fuels will run out before these danger points are reached.

The global warming worry most often mentioned (melting ice caps flooding the coasts) wouldn't be such a noticeable change in the long view. Just inconvenient.

I believe it can happen because I believe CO2 traps heat, which I believe from experiments and the atmosphere of Venus. The ice could melt without much more heating, just more time to finish melting. Maybe 100 years to finish melting (9% per decade estimate, but I assume (at least) the same amount (thus a bigger %) of the remaining ice will melt each decade)

Answer 7

Yes and no. Yes, it would appear that we're living in a cusp between climatic ages, but no, if one insists that we have anything to do with it. Ol' mama earth has gone through changes like this since the sun spat her out into orbit.

As far as the many doomsday scenarios out there, I personally do not worry about it. The way I see it, they can't even get the 5 day forecast right half the time. I'm not about to worry over a 200 year forecast. After all, if you're as old as I am, you'll remember the 70's when the news was filled with dire warnings of the coming Ice Age!

Answer 8

Nobody's asserting that global warming is going to destroy the planet. There is a pretty narrow range of acceptable climates for human life, and the question is whether that range could be breached as a result of human activities. It's not that a postage stamp is destroying the Empire State building, more like the carpet is being replaced on one floor.

Answer 9

No one will disagree with the fact that there was a hole in the ozone layer, and that it was caused by humans (after humans stopped certain behaviors, the ozone started to repair itself).

Anyway, they're not talking about just 30 years of pollution. Heavy industrialization began in the mid to late 1800s in Britain and Europe, with the US soon following. Now with huge populations in China and Southeast Asia becoming industrialized, the human impact is only increasing.

Little things can make a big difference. Just look at how easily a volcanic eruption in a place like Indonesia could adversly affect crops in New England...you might also ask, how can a tiny little virus or bacteria destroy entire segments of the population, like the bubonic plague or the flu?

It is not difficult to disrupt fragile equilibria. We shouldn't assume that one needs large amounts of time to cause harm to those equilibria.

Answer 10

The sky is falling, the sky is falling, the sky is falling...

We humans contribute about 0.1% of the total carbon through our activities. This is small, but could provide a tipping point if we were on the edge. This is unlikely however.

It is more probable that variation in solar output is the key factor here. Solar activity is variable and cyclical and seems to correlate with past geologic markers like ice ages and other global climate changes. Past climatic events probably were not caused by humans living at that time, but....you never know.

We probably should still seek low impact technologies and processes to reduce pollution and damage particularly where we humans live in concentrated areas. The old adage "don't soil your own nest" still has truth in it.

Answer 11

A great lie, your sorry a**. Go ask the fellows in New Orleans and Miami if they think whether global warming is real or not. Or even better, settle there! I'm sure over 20 hurricanes in 2 years would undoubtedly give you the perfect answer to your sorry excuse of a question.
