Something about unusual winds... Can you refresh me, Joe? On the bet: What do you mean by 'essentially' ice free? And are you saying ice free year-round? Let's get the details straight and I might take you up on a very sizable bet. My 401k isn't doing so hot. I could use a substantial retirement fund.

It's a sure loser for you. Even the more extreme melting scenarios look conservative when examined against observed melting from geologic records. By the time they're done, I'd bet scientists are pegging sea level rise by 2100 at 3 or more meters. Ron:

I mean that by the end of 2020, the lowest recorded Arctic Sea ice extent (typically in September) will be under 10% of the 1979 to 2000 average. But Ron, listen to John: You have kids to send to college and retirement to think of -- so I don't want your money. Ron — watch the video, and your first question will be answered.

Right now, it looks like reality is racing ahead of the science, meaning we can't really say with any confidence how bad things will get, whether from CO2 already in the atmosphere or that which we'll surely emit over the next few decades, even under the most optimistic of scenarios.

But you're right, I can't really be betting like that. I just wanted to see the details of what the proposed bet might look like. None of us are in a position to personally verify anything about it anyway. John,
