I wonder what everyone's view on Global Warming is?
I will present two cases of argument about global warming and you guys and gals judge which you believe.



CASE 1

Global Warming in the past 100 years is mainly caused by the over industrial human activity. Rising populations and modernization has led to a new line of poplutants from fridges to cars to power plants. These contribute directly to greenhouse effects and thus the measured temperature rise over the past 50 years.


CASE 2

50 years??! That's barely measurable in the 450million year earth history. We can not conclusively say we are responcible for a temperature rise just by looking at 50 years of available data. Volcanic erruptions, solar activities do far more damage to temperature stability than 100 factories and millions of cars. To put all our resources in curbing petroleum usage is futile, because not only are they running out anyway, but a mere volcanic erruption will set us back 100 fold. We should concentrate of critical enviromental things that will make a difference.
