Global Warming

Another point I forgot to mention is the fact that we have only had the means to create greenhouse gases for 50 or so years. We had automobile in the 20's 30's 40's but were not used very much AT ALL something like 4% of what we have today. So for 50 years we have been building buildings driving cars so on so on and so on. If only 50 years of this greenhouse producing machines has done this damage so fast, we are heading for trouble.. connsidering how much we have come since then lets just picture a world in another 50 years from now. My point is this... Man in so little time could not have been able to produce so much damage. If we go on the fact that we have had the ability todo this then we are heading for some dark times very fastly

"Man in so little time could not have been able to produce so much damage."


I don't know what you do for a living, but there are a great deal of men and women in the scientific community who can prove otherwise.


Sadly, man's efect on the environment and atmosphere is anything but a myth. From holes in the ozone layer, to the deforestation of the Amazon, man bears the guilt of damaging the environment THAT THE LORD CREATED!!


Probably coincidence..... in the last 120 some odd years that we have been keeping global temperature stats, the three warmest years have been 1998, 2002 and 2003.

The deforestation of the amazon is not done by man! look at the garden of eden did man do that too?

Last year or so, I came across some excellent satellite photos of the collapsed Larsen B iceshelf in the Antarctic which I can't seem to locate, but the link below provides some hard data. If you compare present day photos of the north and south poles with those from ten years ago, the melting and breaking away are plainly visible. This phenomenon is measurable, but I suppose the cause is yet undetermined and controversial.

Huh? No, I was saying that I think global warming is real. Also, we should all just use electric cars!

So who is cutting down all those trees?

I like the electric car idea. We have enough wind, water and sun to power everything we need. All we have to do is make it efficient and affordable. And we all know that won't happen until it absolutely has to happen. If the oil guys could be persuaded to make the transistion, it would happen $$$$$$. M

The problem with electric cars is the source of electricity to power them. Many areas still have coal and other highly poluting power plants. Hydrogen is a much cleaner and more abundant fuel for cars.

If 'scientist' and 'ecologist' are not real jobs, just wondering what what qualify? What do you all do for a living? As long as its not in advertising or marketing...

So called 'Greenhouse Gases' are a problem because they prevent a greater percentage of radiant heat from leaving the atmosphere, instead reflecting it back inwards. The problem with burning fossil fuels is that it makes great changes to the Carbon cycle- thousands and thousands of pounds of carbon that have been locked away from the cycle for millions of years are now being put back in at unprecidented levels. The effects of such action is disputed, but to believe there will be no effect is naive.

If Global warming is indeed occuring, and continues to occur, one possible result, as others have mentioned, is changing of weather patterns. This can lead to some proposed advantages, such as milder climate for Siberia, but may also turn plains, often major agricultural producing centers today, into deserts.

I like the electric cars too. We could all be driving ,at the very least, electric-hybrid cars in the next few years. but, my guess is that we won't be.

Which leads me to one question I always have with the Arctic Oil Drilling push- the oil's there, its not going anywhere, no one else can come drill for it, what's the hurry? Why not save it for a rainy day when oil is really hard to get and we could definately use the extra energy? My guess is that there are some people who just really really want to be the ones to get to drill it and profit from it.
