The Telegraph in Britain has a story about a massive iceberg which broke off from the Antarctic ice cap and is heading for Australia. The iceberg is so large that if it hits the mainland it would cause a 3.0-4.0 tremor on the Richter scale. That’s a really large chunk of ice.

The mammoth chunk of ice, which measures 12 miles long and five miles wide, was spotted floating close to the mainland by scientists at the Australian Antarctic Division (ADD).

Known as B17B, it is currently drifting 1,000 miles from Australia’s west coast and is moving gradually north with the ocean current and prevailing wind.

Dr Neal Young, a glaciologist working for the ADD, said that if the iceberg eventually reached Australia waters, it would crash into the continental shelf causing a magnitude three to four tremor.

This is the sort of story which is used by global warming activists to predict the end of the world. But there were a couple of interesting points in the story.

First, how the iceberg was spotted:

Dr Young originally spotted the iceberg using satellite images from Nasa and the European Space Agency.

Second, some historical context:

Dr Young said an iceberg the size of B17B had not been seen so far north since the days when 19th century clipper ships plied the trade route between Britain and Australia.

Hopefully you have picked up on what I picked up on. There have been icebergs this size since at least as far back as the 1800s, but we did not have satellites to spot them with any consistency, and therefore have scant historical records to which we can compare current events.

This highlights something profoundly troubling about the politicization of global warming science.

Those who stand to profit politically and economically refuse to acknowledge that we are limited in our historical knowledge of measurements which depend on technology that did not exist less than a century ago. We also have limited knowledge of historical events which, when they happen today, are said to reflect manmade global warming.

This is just an iceberg story. Nothing to see here, move along.
