Forecast: Heavy Weather
The weird weather does tend to concentrate the mind, though. Even George W. Bush acknowledges the scientific consensus that climate change is real. Most people, even conservatives, now have no problem taking the next step and acknowledging that human activity -- the burning of fossil fuels and the release of heat-trapping carbon dioxide into the atmosphere -- is causing climate change, or at least accelerating it.
Beyond those fundamentals, though, are a couple of even more inconvenient truths that few seem ready to come to terms with.
Geologists: Collier Glacier is shrinking
Between the North Sister and Middle Sister in Oregon's Cascade Range, Collier Glacier has advanced and receded for hundreds of thousands of years. But like many glaciers, it is headed in one direction these days: backward.
It is in serious peril, says geologist Ellen Morris Bishop of the Fossil-based Oregon Paleo Lands Institute. "We have basically a really sad picture of Collier Glacier today."
Climate change: Fossil record points to future mass extinctions
Global warming could cut a swathe through the planet's species over the coming centuries, warns a study released Wednesday that shows a link between rising temperatures and mass extinctions reaching back half a billion years.
White House edits CDC climate testimony
