His evidence:"'I think one of the best ways of thinking about it is imagining that the base line has shifted,' Tim Flannery, the commission’s leader, told the Australian Broadcasting Corporation. “If an athlete takes steroids, for example, their base line shifts. They’ll do fewer slow times and many more record-breaking fast times.”'The same thing is happening with our climate system,' he said. 'As it warms up, we’re getting fewer cold days and cold events and many more record hot events.'" (NY Times "Report Blames Climate Change For Extremes in Australia")
"At least 123 weather records fell during the 90-day period the report examined. Included were milestones like the hottest summer on record, the hottest day for Australia as a whole and the hottest seven consecutive days ever recorded. To put it into perspective, in the 102 years since Australia began gathering national records, there have been 21 days when the country averaged a high of more than 102 degrees Fahrenheit (39 Celsius) and eight of them were in 2012."
Of those who denied global climate change for years and years and now accept that it is happening, many still deny that it is human caused. Of those who acknowledge human's contribution, many believe there is nothing we can do about it except work on mitigating the effects.
The concerns I have with Arctic oil drilling are not simply concern about the possibility of an oil spill in the Arctic Ocean. My longer term concern is that we continue to go after energy sources that exacerbate climate change and make the long term damage worse. The $5 billion that Shell says they've already invested in Arctic drilling in Alaska would have been much better spent on developing affordable alternative energy.
But those whose aptitudes and expertise are geared toward drilling oil, and who work for multinational oil companies whose infrastructure is aimed at drilling oil, are like addicts in denial. Their life work, not to mention their life style, are all built on the belief that they are doing the world good by supplying us with oil. To accept the idea that they are also contributing to climate change which could lead to the submergence of island nations and low lying geography like Florida and Manhattan, is in conflict with who they are and what they do.
And while they gained wealth and privilege through their oil work, even the enormous wealth of the oil companies cannot compensate for the damage that will come.
