Methane and Worrying about the Future

Worrying about what might happen is a fairly useless pastime unless you have the means of preventing what might happen. If you worry about a massive asteroid suddenly breaking away from its orbit and colliding with earth you are indulging yourself.  If it happens we cannot prevent it. However there are some things about which you can worry because your concern may lead to solutions, for example, the amount of methane trapped under the ice in the Arctic and the northern tundra and taiga.
