If Mann-made global warming causes icebergs, what caused the berg that sunk the Titanic in 1912?

You'd think warmists would get tired of all the silly fear mongering stories.

Icebergs are normal. If there weren't any icebergs, we'd be going back into another ice age with a glacier sitting on top of both of your houses.

Imagine Puget Sound under a mile of ice. 20,000 years ago, glaciers covered everything in between the Olympics and the Cascade mountains and spread as far south as Olympia.

The ice over Seattle was higher than five Space Needles (3,412 feet.) Glaciers advanced from Canada and retreated four or more times. Over a few million years, Puget Sound was carved and scoured by glaciers.

About 15,000 years ago, the Vashon glacier begins to melt and recede from lands that will come to be known as the Puget Sound region and the Columbia Basin region. By 11,000 years ago, the glacier has retreated to the border of present-day Canada. During its advance, the glacier had carved out Lake Washington, Lake Tapps, Lake Sammamish, Puget Sound, and Hood Canal. The other major shaper of the land -- the pushing of the Pacific Plate underneath the North American plate, and the docking of terranes (fragments of continents) had already occurred long ago.

The Vashon glacier was the last "stade" (a glacial advance and retreat) to cover the region. It was the last glacier of the Pleistocene Epoch, which lasted from 2 million years b.p. (before present) to about 10,000 years b.p. As far south as the Seattle area to the west and the Spokane area to the east, the glacier, at its thickest, reached 3,000 feet of ice. To give a comparison, the Pacific Northwest's tallest skyscraper (as of 2003), Seattle's Bank of American Tower (Columbia Tower), is about 997 feet tall.
