Confession, I'm with you, I believe this warming trend is pretty much out of our hands. I believe it's just the earth doing what it has for millions of years, continually renewing and changing. That however is no excuse to indiscriminately pollute the environment since as we all know this is having repercussions in our air quality, water and food supply. We should all work together to better our planet, all the while knowing that changes are going to occur.
I watched that program on National Geographic on the warming issue, and read some news that Scientists have discovered evidence of a tropical climate in the north pole I don't remember precisely how long ago that was, but they have pulled out of the arctic ocean remains of tropical plants and animals only known to survive in tropical weather. They think the weather there remained at around 74 degrees farenheit at this time. With this in mind, I don't think it's very wise to reconstruct cities like New Orleans, or live anywhere near the coast since these areas will continue to be greatly affected by severe weather and erosion. As the polar ice continues to melt, it will be amazing to see, what interesting things will be uncovered, maybe ancient civilizations that were eradicated when the last ice age hit, or new species never before discovered, who knows? Maybe the polar region will one day be one of the earth's hot new vacation spots !
