What is a fast 1500m swim time?
Strong swimmers are generally going to swim in the 1:30/100 range or faster. If you are swimming faster than a 1:30 pace then you will generally be top 10% or so out of the water for an AG swimmer. Depending on the race, you may have some “super swimmers” that show up and compete.

Is Antarctica melting?
Since the early 1990s, Antarctica has lost roughly three trillion tons of ice. Today, the rate of loss is accelerating as warm ocean water melts and destabilizes the floating ice shelves that hold back West Antarctica’s glaciers, causing those glaciers to flow more quickly into the sea.
How fast could Antarctica melt?
Antarctica’s ice sheet could retreat 20 years sooner than expected. Factoring that in, the melting ice could raise the sea level by an additional 2.7 to 4.3 inches on top of the 10.6 to 14.9 inches that simpler models predict by the year 2100.
