Wowser! Of course all life on Earth will be extinguished by the 2029 asteroid if it hits the Earth. Which do you think is the more pressing problem?
Nice image. Thank you.
What is the accepted volume of Greenland’s ice cap: I know in places it is very thick (over 5000 feet in limited regions), but in others it is only a few hundred feet thick.
Too many people look at a Mercator projection map and think the Greenland ice cap is uniformly 5000 ft thick and thousands of times larger than it really is.

The thing is...the East Antarctic ice sheet has nearly 80% of the world's ice (and its growing). Greenland has less than 10% of the world's ice. I read one source that had the growth of the East Antarctic ice sheet at five times what Greenland was losing.
