We call Acela trains that average 65 mph “high speed.rail.”
Chinese trains are 200 + mph.
City to city high speed rail is required to compete internationally.
Many US cities will be underwater before high speed rail is ready.
What especially worries scientists is if the melting accelerates. If all the ice on Thwaites is lost, it would raise ocean levels an additional 2 feet, according to the NASA study. But the glacier also backstops neighboring glaciers. If those glaciers also melt, sea levels could rise an additional eight feet, researchers warn.
One of Antarctica's biggest glaciers has a giant hole under it. What would happen if it collapsed?
