Chesapeake gives early warning of climate disruption
Chesapeake beach communities are rapidly losing their beaches! An article in today's Washington Post says,
Sea levels are rising almost twice as fast in the Chesapeake region as in most of the world . . . Two natural phenomena mean that sea levels will rise faster along the mid-Atlantic than almost anywhere else in the world.Global Climate Disruption is here now, it's just not evenly distributed yet.
First, the mid-Atlantic is sinking. It is an echo of the last ice age, when huge glaciers pushed down on the Earth's crust to the north. The land here was lifted like the other end of a seesaw, and now it's slowly dropping. Second, research presented last weekend shows that climate change will alter the dynamics of the ocean, weakening a system of currents that pulls water away from shore here.
At the same time, the world's oceans are inching up -- fed by melting polar ice and swelled as warmer water expands in volume. The U.S. Environmental Protection Agency, echoing a United Nations science panel, said it is "very likely" that man-made greenhouse gases are primarily to blame.
