I think the Intergovernmental Panel on Climate Change is selling a best case scenario. The sea level is not going to creep up. I was walking in Miami Beach with my daughter last weekend, and told her that one day she will be able to tell her kids about how she walked in Miami before it was gone. And they’re worried it could be getting worse. Some researchers are concerned that the giant glacier could become increasingly unstable in the coming years, eventually spiraling into a pattern of unstoppable retreat. If that were to happen, it could potentially unleash enough ice to raise global sea levels by 10 feet.Glacier, which has recorded some of the most rapid melt rates out of anywhere in Antarctica. Currently thought to be pouring about 50 billion tons of ice into the ocean each year, scientists estimate Thwaites is responsible for about 4 percent of global sea-level rise all on its own.
