“...The resulting explosion packed the energy of 700 1-megaton nuclear bombs, and even an observer hundreds of kilometers away would have experienced a buffeting shock wave, a monstrous thunder-clap, and hurricane-force winds...”
“...The impact would have melted 1500 gigatons of ice, the team estimates—about as much ice as Antarctica has lost because of global warming in the past decade...”
it just goes to show you didn’t even read the article.

Yeah ... as soon as the article insulted my integrity, I quit reading ... you need to take a deep breath and focus a bit on what you're saying ... from now on, I'd like for you to start being suspicious of sources that use "megatons of TNT" as their unit of measure ... so often that's used to deceive the reader ... as it is in this case ...
"700 1-megaton bombs" is an obvious deceit ... yes, our bombs can be dialed back to 1 megaton, but their maximum yield is 10 megaton ... the largest bomb was 50 megaton, videos can be found by searching "tzar bomb" ... so why not use that?, 14 tzar bombs worth of energy ...
Next problem is
8th grade math ... if all the energy released by these 700 1 megaton bombs was used to vaporize ice ... we'd only melt 1 gigaton, not the crazy stupid 1,500 gigatons your article is claiming ... that was obvious at first glance ... I can forgive you not appreciating how much energy it takes to vaporize ice, fair to say 2,600 J/g is enormous?, hate to use the weasel word, but that's the number we're
dividing by ... thus enormous eh? ...
For homework ... I want you to use the density of water and calculate the volume that 1,500 gigatons would occupy ... then divide by the surface area of the world's ocean ... this should give you sea level rise this past decade from Antarctic melt only ... remember, we've only measured an inch, so please tell me how many kilometers your calculations differ from this measured value ...
Haven't even started on the physics mistakes ...
