I think if there is any damage its already done and not reversable. The earth naturally renews itself all the time. But we can do as much as we can with other sources of energy but at the same time and like I said China America and India are huge polluters so me as an individual am wasting my time changing my ways by taking less flights and such. China pumps out stupid amounts of pollution so whatever I do is a waste of time. Are we seriously ever going to control population or building more and more across our lands. Probably not. This makes me believe not much will ever be reduced. As for renewable energy well its a tough one to answer.

So because in World War II over 70 Million people were killed it does not matter if you kill one or two? You have a very self-comfy logic...

What prat said there was a hole in the ozone layer. Seriously if there was a hole we probably would'nt breathing now. If aviation fuel is causing so much damage what do you think is going to happen? Nothing. Do you seriously think its going to stop or be cut it never happens. Yes your thinking if everyone else had my attitude we will all be doomed. Rubbish. Do you think MP's are going to do what they ask YOU to do. No. Because its all complete crap they tell you whatever they want. Ice caps melt and break away into the atlantic all the time its nothing new. Sorry I am not just being blind or ignoring it I just dont believe it. The world changes naturally all the time. Yes we are polluters but I see no difference in our weather around the world than I seen when I was watching the news as a kid in the late 70s or 80s.

Ice caps do not melt or break away all the time, they melt during summer time. The fact is that it now melts far more rapidly and earlier in the spring time. To such an extent that re-icing in autumn and winter does not replace anymore what has been lost during spring/summer. With the net result that the north pole ice cap has lost almost 2/3 of it's mass during the late few decades, and that, if nothing changes, north ice cap will completely disappear during summer in 10 to 20 years. Imagine, the north pole being only sea.

Well I think that sitting back and doing notihing is not the answer. I think its up to developed countries to lead the way and combat the damage that has been done already. If europe makes the effort then I'm sure other countries will follow.

But countries like America and China have already said that if cutting emissions is going to affect their growing economy then they wont comply. Im not saying everyone here is wrong its just what I think and do hear all the time. From what I hear I dont think the Chinese government care which is wrong.

Mining uranium ore is a dirty business, and tied in with the greater risk of using nuclear energy, I don't think it's viable in the grand scheme of things. The stupid "bury the CO2" idea is more enticing than nuclear energy.
Wind and wave, and for our transportation, hydrogen. Not just fuel cells - I'm hoping to see a safe hydrogen combustion engine. There should be some manufacturers toying with the idea.
And also, uranium is only available for about 100 years.
Indeed the "bury the CO2" is completely stupid, because what is done is move away and release CH4 to replace it by CO2. Unfortunately, CH4 is also a very efficient greenhouse gas.

Yes, putting CO2 underground is stupid.
US politics has already changed with Obama and the Chinese government also has global warming and other environmental issues set on its agenda, but remember, it still is the Chinese government, not Greenpeace, so only small steps are to be expected. But every step in the right direction is better then nothing. Blaming governments is also too easy, consumers are voting and shopping so we as consumers can support change. Buy a GreenHeart instead of a normal product and it also probably improves things in China since SE is producing there (donno where the GreenHearts will be produced exactly though).

And let me state one important thing: It is not climate change that is important, it is the speed at which it changes. Because if it goes too fast, we won't be able to adapt due to the way our society is organized.
Moreover, the raise in temperature we are discussing is a global phenomenon. Meaning that it is the mean values of the temperature over the all earth that is raising. Locally it can raise or drop dramatically depending on the reorganization of the atmospheric and sea currents, which can happen for very small changes in the temperaure.
One example: Due to the raise in temperature, most of the ice in Russia, Siberia etc. is melting and the resulting fresh water go into the arctic sea. Salt content of the sea water is changing, and as it is that salt content that is the motor driving the Gulfstream, the latter might well stop completely (it is already slowing down significantly). Unfortunately, the Gulfstream is one of the oceanic currents that redistribute the heat mostly received in the tropics. Once this happens, North America and Europe will completely freeze and no crop will grow anymore, followed by the death of most animal species.
Now, what will we do if this happens? The sad answer is: Invade the hotter countries south, which means wars for food.

Hang on a minute I thought the world was heating up not the gulfstream changing course or stopping and we are back in the ice age. Surely if its global warming then why is the ice caps melting if we are about to freeze? Ya never got that idea from The Day After Tomorrow film did ya? I believe everything you just said then is a natural cycle nothing more.

Read carefully what I wrote. Let me break it down into succeeding effects:
Global warming means an increase of the mean temperature of the earth.
Such an increase melts the glaciers, bringing huge amounts of fresh water in the arctic sea.
Which in turn stops the gulfstream.
As a consequence the heat collected from the sun in the tropics is not redistributed.
Final effect: North America and Europe will freeze. On the other hand temperature in the tropics will raise.
