It would be stupid and naive to assume that the worlds warming problems are soley associated with mankind and our pumping of Co2 into the air.
From what I have read, scientists state that the average world temperature about 1500-2000 years ago, was about 2C warmer than our average temperature today. Hhmmm, the polar bears survived, mankind survived ... maybe there's a bit of hocum going on today?
I'm of the opinion (as are a lot of other people), that Climate Change has grown into a huge industry. And that industry must keep propelling itself on and on to sustain itself. And how do you do that .. you create so much hype around climate change that you end up in the governments pockets.
I'm all for cleaning up our planet, but lets be realistic about it and not let ourselves become the victims of sensationalism. The world is not going to end. If water levels rise, its quite possible they would have risen irrespective of humans being on the planet.
The only thing that really affects us globally now is that we've become a race that is accustomed to living next to the oceans and seas. Which is not good if water levels rise. Thats's our fault for building cities so close to the water. Of course, we're not to know a hundred years ago that the worlds climate is dynamic and constantly changing. What happens if we have a mini ice age in a hundred years time? (or a full on Ice Age for that matter).
In reality, humans have been on this planet for a mere speck in time. We haven't been here long enough to witness all of natures weather and climate changes. An ice age may last for 3000 years, as may a warmer patch. What if we are just seeing the end of a mild climate era, and now we're heading into the warm cycle. It could be warmer (than our ''norm'') for the next 2000 years. If the pro climate change people feel they are so correct in their assertions, why aren't they pushing governments to re-locate cities that will potentially be under water in the next 50 years. New York and Sydney may end up being 200 kilometers inland from where they are now?
In addition, maybe it won't be so bad if it does warm up a bit. If I remember my lessons at school, when it warms up, there is more evaporation from the seas. That evaporation turns into large water droplets, and eventually large water droplets fall to the earth as rain. Soooo ... maybe previously dry areas like the middle of Australia and Sahara Desert may end up being lush and green. OK, we might not have as many polar bears, but we may have a better chance at feeding the starving millions that we'll have in 50 years.
If you listen to some pundits, water is going to be a much needed and rarer commodity in the future. Therefore, if it rains more (due to global warming), that's a good thing - right? We might get the chance to use previously dry and arid land for farming. If we get enough rain, we could build more dams for hydroelectric schemes to generate more eco friendly electricity. Of course, we'll be buggered in 2000 years when the next ice age settles in!! But, I'm not going to get too upset about that!
