Re: I sea swelling
Whilst I cannot disagree with the fact that the earth is warming I am completely unsure that it is us who are causing it.
So, you might say "cause and effect". We have increased our output of CO2, and other harmful gasses into the atmosphere. Is Earth really that delicate? Did/can the planet survive?
"You say did?" I hear you ask. Well our planet was much more volatile in the past, probably due to increased volcanic activity, the sun having more fuel to burn perhaps and other stimuli which we probably dont even understand.
I once heard that cows produce a damn lot of methane and CO2 which is also harmful the environment. So much so that our large scale farming of these creatures causes as much CO2 as we do directly (correct me if im wrong). The greatest 2 contributors are the ocean and volcanoes. These 2 account for some massive percentage so again, I'm led to believe, are we right?
The beauty of science is that all science is fact until its been disproven by something else. I'm not saying we are wrong, but we could be, and perhaps we need a little more faith in the old girl that she will see us right. I mean she survived the dinosaurs right? Oh wait.... :S
But in all seriousness, I believe in the 70s climatologists were terrified the planet was cooling and encouraged the burning of fuels to generate CO2, think it had an effect?
Mankind has 3 things it needs to do:
1. Nuclear Fusion
2. Easy, accessible space travel for all
3. Flying cars (like Back to the Future, none of this propeller/winged nonsense)
Then there will be no CO2 to worry about.
