Human Garbage Watch presents Don Surber

Since 2003, two trillion tons of ice in Alaska, Greenland and Antarctica melted and never reformed.

This guy thinks Greenland, Antarctica and most puzzlingly Alaska, literally float on the water.

Question: What do you think of 2 trillion tons of ice melting since 2003?

Answer: Not much. It is a scary number that is not put into context. I suspect there are quadrillions of tons of ice out there. When the media uses a scary number, it is because the percentage is small. When the media uses a percentage without using a base number, it is because the number is small. For example, murders doubled without the number could mean 1 murder last year, 2 murders this year.

Question: But doesn’t melting ice raise the sea level?

Answer: Not really. James O’Brien, an emeritus professor at Florida State University: “When the Arctic Ocean ice melts, it never raises sea level because floating ice is floating ice, because it’s displacing water. When the ice melts, sea level actually goes down.

“I call it a fourth grade science experiment. Take a glass, put some ice in it. Put water in it. Mark level where water is. Let it met. After the ice melts, the sea level didn’t go up in your glass of water. It’s called the Archimedes Principle.”

I know when you look at a map it looks like land is floating on water, but it's actually attached to the crust.
