So that sounds nuts (and suspectedly alarmist/political) but it's a nasa.gov link, so...
After reading, it is true but indeed needlessly alarming. Changing underground water levels are influencing the rotation of the Earth, but it's mainly happening in India and East Europe, way far from the east of France.
Key quote:
"The researchers found the answer in Eurasia. "The bulk of the answer is a deficit of water in Eurasia: the Indian subcontinent and the Caspian Sea area," Adhikari said.
The finding was a surprise. This region has lost water mass due to depletion of aquifers and drought, but the loss is nowhere near as great as the change in the ice sheets.
So why did the smaller loss have such a strong effect? The researchers say it's because the spin axis is very sensitive to changes occurring around 45 degrees latitude, both north and south. "This is well explained in the theory of rotating objects," Adhikari explained. "That's why changes in the Indian subcontinent, for example, are so important.""
