What is the likelihood of our precipitating a "methane gun" event?

100% ? IIRC we might have prevented it with serious changes a couple years ago, but now it's going to happen and is already happening.

FWIW, the folks in askscience say that the research as of one year ago does not suggest any catastrophic clathrate gun that would actually be triggered by current rates of warming.

If that's true, then my understanding is that 4 degrees of warming is inevitable, and 5 degrees is likely. 6 degrees probably isn't ruled out.

Do you have children? I have a teenage son. A heretofore normal lifespan for him will bring him to the late 21st century.

I can hardly think about what things will be like then.

When my daughter is the age of my grandmother, it will be the 22nd century.

That's incredibly sobering.

... and I'll probably be 20 years in the grave.
