Wait till the Yellow Stone Caldera
blows, you want to see global climate change. Of course most of North america will be devastated, but hey...that's life.

Yea I watched a couple of shows on the Yellow Stone situation. I live in NY and I know when it goes, all the little problems I worry about now will be gone.

dramatic warming of the Earth's atmosphere that raised sea
temperatures and killed off many marine species, resulting in a

sea surface temperatures by 5 degrees Celsius (9 degrees F) in
the tropics and more than 6 degrees Celsius (11 degrees F) in
the Arctic and increased the acidity of the oceans.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.yahoo.com/s/nm/20070426/sc_nm/volcanoes_warming_dc_1">The resulting "planetary emergency," as scientists have
