"Global warming sure is a threat . Some of the Polar Ice Caps already melted . Average temperatures have rised since 50+ years ago at a constant rate . We better stop polluting now , or we will be in big trouble ."
"The Polar Icecaps have been melting for the past 14,000 years according to experts . Many in the scientific community believe that it would be another 100-1000 years before the melting of Polar Ice becomes a factor in the rise of sea level . What they believe is more important is the thermal expansion of the world 's water that comes with the increase in the oceans ' mean temperature . Some predict that the rise in sea level could be 3 ' by 2100 , so do n't invest long-term in any beach-front property that is n't on tall stilts and you 'll be OK ."
