The thinking here is that shareholders may have been objecting not just to Citigroup CEO Vikram Pandit's US$ 15 million dollar pay, but also to the $ 10 million retention payment awarded to him, and
the general lack of correlation between Pandit's pay and the company's financial performance.
I will try to get some more specific answers for you and either correct or fill out this article, but I think the main gist
of the argument is that there are other factors at play and the simple
lack of a perfect
correlation does not mean that CO2 is not the primary driver
of the
general warming seen since 1900.
