This just in from my brother via email:

A slight correction to your blog. We're not going to die in 2056. We're in fact not going to
make it past 2036 when the giant asteroid hits.

So live it up and don't worry about global warming. Because there's
going to be some extreme global heat in 2036...

Thanks JP! It's always good to keep things in perspective!
