Our top climate scientist has sent out a really, really long email (where
does he find the time?), mostly discussing comments on his
recent email essay on coal. I think Hansen is the clearest thinker on
climate among the top scientists in the field, so I will reprint the
email, breaking it up into several postings. The first one addresses
“Coal-CO2 versus Oil-CO2”
(
a query that was also raised by a commenter here)
