News media around the world have been all abuzz, with headlines declaring “Irreversible collapse of Antarctic glaciers has begun” and “West Antarctic Ice Sheet collapse is under way.” The “rapid” collapse threatens to cause sea level change of 4 to 13 feet. Calamity will surely follow. “Collapse will change the coastline of the whole world” shrieked the UK's Guardian, always a good source for mindless rumor mongering. What they are referring to are a pair of new reports that say the West Antarctic Ice Sheet (WAIS) has pushed its way over a submerged ridge that had been impeding its forward progress, causing the ice sheet to become unstuck from the sea floor. The WAIS is now flowing more freely, and hence more rapidly, into the sea. What the alarmist headlines don't say is that any impacts from this change are centuries to millennia in the future.
The science is settled, the President of the United States assures us. His pet scientists have produced yet another frightening climate report to prove it. Given this President's tenuous relationship with the truth on other matters, a citizen might pause to ask if the claim of settled science is, in fact, true. In the recent past scientific papers have discovered some “unexpected” phenomena that help to regulate climate. In fact, one of the climate change faithful proposed a mechanism affecting the jet stream that could be responsible for this winter's unexpected weather in the northern hemisphere. Only problem, a number of climate alarmist luminaries have dissented from her idea. Remember the consensus that was supposed to shut down all opposing opinions? Never mind. Another study shows statistically that there is no way to establish a human caused warming trend without another 100 years of observation. Of course, if you believe the climate catastrophists the world as we know it will have vanished by then. So is climate science really settled? Here are just some of the most recent indications that it is not.
