What if all of Earth’s ice melted?

What would Earth be like if all of its ice melted? New short video from the guys at AsapSCIENCE, featuring Bill Nye.

This is a good video from ASAPScience about what would happen if all of Earth’s ice melted. It points out some important ongoing practices in the Arctic, for example undersea seismic blasting, which is used in the search for oil and which affects Arctic wildlife.

However, one thing this video does not do is give the timescale for scientists’ projections on ice melt and sea level rise.

Yes, the level of Earth’s seas is rising. Global sea level has risen by about 8 inches (20 cm) since reliable record keeping began in 1880, according to the very comprehensive National Climate Assessment report, produced in 2014.

That same reports says that sea level is projected to rise another 1 to 4 feet – up to 1.2 meters – by 2100. That’s a long way from the 70-meter sea level rise discussed in this video.

The real danger in our century from sea level rise is not inundation of many coastal cities by the sea. The danger is that – during extreme weather events – there’s an increased risk of storm surge and flooding, such as that in New York City when Superstorm Sandy struck in 2012.
