It is not just a bomb that can blow the arctic. It can destroy all human civilization. And at this point, we may have lost any ability to do anything.

Edit: Doom scale...

1 Inconvenient storms.

2 More frequent natural disasters.

3 Destroying coastal cities.

4 Causing hunger, wars and mass migrations.

5 Decimating human population.

6 Destroying human civilization.

7 Destroying all humans on earth.

8 Destroying all life on earth.

9 Destroying earth.
