Take a look at this graph that shows global temperatures over the last 900 million years: http://www.google.com/imgres?lr&safe=images&sa=X&hl=en&as_qdr=all&tbm=isch&tbnid=dxfUyQfAJcSA2M%3A&imgrefurl=http%3A%2F%2Fdrtimball.com%2F2011%2Fipcc-exclusions-and-inclusions-of-climate-mechanisms-are-both-failures%2F&docid=7PIkRDk-CJD4GM&imgurl=http%3A%2F%2Fdrtimball.com%2Fwp-content%2Fuploads%2F2011%2F02%2Festimated-global-temperature-over-900-million-years.jpg&w=600&h=393&ei=PJAcU7vxC4O42wWK14HoBQ&zoom=1&ved=0CGkQhBwwBw&iact=rc&dur=8297&page=1&start=0&ndsp=32 Or if that's going back too far for your tastes tale a look at at temperatures over the last 10,000 years: http://www.google.com/imgres?lr&safe=images&sa=X&hl=en&as_qdr=all&tbm=isch&tbnid=SOadANpetBK6qM%3A&imgrefurl=http%3A%2F%2Fjoannenova.com.au%2F2010%2F02%2Fthe-big-picture-65-million-years-of-temperature-swings%2F&docid=UrLd2hoOeD7sWM&imgurl=http%3A%2F%2Fjonova.s3.amazonaws.com%2Fgraphs%2Flappi%2Fgisp-last-10000-new.png&w=829&h=493&ei=PJAcU7vxC4O42wWK14HoBQ&zoom=1&ved=0CF0QhBwwAw&iact=rc&dur=1444&page=1&start=0&ndsp=32 John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
