Lehman Brothers, the global financial services firm, just released a new report entitled The Business of Climate Change II: Policy is accelerating, with major implications for companies and investors.
The precursor to this was back in February 2007: The Business of Climate Change: Challenges and Opportunities.
I have yet to read either report - but leave a comment if you have.
Probably nothing you haven't heard before but remarkably comprehensive view of global warming. Interesting that they're written by a bank; and when banks talk businesses tend to listen.
