Topic: High Tides

A massive storm surge in Boston resulted in the highest tide ever recorded in the city, leading to widespread flooding. Media reports immediately attributed the event to global warming, though the hosts point out that similar floods occurred in 1978 and 1921. Dvorak reports from the San Francisco Bay, noting that local mudflats remain unchanged despite "super tide" warnings.

NOAA's Tide and Current Program is investigating why tides along the U.S. East Coast have been running six inches to two feet higher than normal since June. While officials state global warming is not the cause, the hosts speculate on other factors such as shifting magnetic poles or changes in the ocean floor.
