Oregon: Gore-trained politician gives barking-mad climate presentation at U.S. Fish and Wildlife Service Forensics Lab

MailTribune.com: Bill Bradbury tailors Al Gore's global warming speech to Oregon
Bradbury, who was trained in the climate change presentation years ago by former Vice President Al Gore, has focused it on the Northwest, including predictions that, because of global warming, the Rogue Valley will have less snowpack, a hike in summer temperatures of 115 degrees by 2080, earlier snow melt, more rain, more flooding, more streams going dry in summer, fewer fish, more wildfires and fewer conifer trees.
...
Bradbury said "as we are painfully aware," wildfires are increasing at a radical rate, which he demonstrated on a graph, showing about five times the fires now as in the 1990s because of warming and drying of the climate.

Many climate models have proved off the mark by underestimating the impact of greenhouse gases, Bradbury said, noting that a 5 degree increase in atmospheric temperature would not be evenly distributed but would likely end up as 1 degree at the equator and 12 degrees at poles, leading to earlier ocean level rises than anticipated.

The effect could be summed up as "the worse it gets, the worse it gets," he said, because the warmer it gets, the more ice melts and the less it reflects sunlight off the planet, so it gets still warmer faster.

The Arctic ice used to cover an area about the size of the lower 48 states, but now it would only cover the part west of the Mississippi — and the Greenland ice cap is melting twice as fast as it was a decade ago, he said. Ocean waves striking Oregon average 4 meters high, compared to 3 meters a few decades ago.

Most of the graphs on Bradbury's charts were steady through the years, but began a steep spike in about 1980. Carbon dioxide, the main greenhouse gas, held at around 300 parts per million until that period; it is now 387 ppm.
