Gwynne Dyer has posted a column
talking about how work by researchers at Reading University have shown
that trying to control global warming by injecting sulphur dioxide into
the atmosphere would lead to a 30 percent decline in rainfall in most of
the tropics.
While we might need geo-engineering techniques as
stopgap measures, we are extremely unlikely to achieve anything without
addressing the root of the problem. Climate scientist James Hansen has
called for a global carbon tax with the proceeds to be distributed to
all, a proposal he calls fee-and-dividend. I have posted a petition
based on his proposal on Care2. You can view the petition (and hopefully
put your name on it) at www.thepetitionsite.com/286/384/042/petition-for-a-referendum-on-a-global-carbon-tax/
