First off, Suttle's a Canadian.
Second, his area of expertise is marine virology in the world's oceans, so OF COURSE he's gonna be more concerned about rising sea levels.
But Pithovirus Sibericum was found in melting permafrost, not in the ocean.
C'mon man - - think a little.

So he's not only Canadian, he's an "expert" about something "little is known about." Yeah, and I'm an expert on how to make burritos on Mars. If I was concerned about viral effects on sperm whales or puffer fish, maybe I'd listen to Suttle.
