I was chatting with someone recently who questioned the veracity of Al Gore's claims about global warming in "An Inconvenient Truth." According to the AP, a report commissioned by the U.S. Congress was delivered today reporting that the earth's temperatures are now higher than they have been in at least 400 years, adding that humans are impacting recent global warming and were the cause of half of the increase in hurricanes.
