  •  Land rebound is due to loss of the glaciers (4+ / 0-)

    And not due to any marginal loss of water. Chicago used to be covered by over a mile thick layer of ice, along with most of the Midwest. It is the loss of all that ice that is causing the land to rebound.

    The land was rebounding when the water levels were their highest, and it's still rebounding just the same. The percent change in water weight compared to the loss of all that ice is a rounding error.

    There is human caused climate change, but we must learn to separate those effects from all the natural changes that always have been at work. The land is rebounding due to the difference between now and 15,000 years ago, not 100 years ago.
