Please review the evidence that was presented by the All-star panel
of climate experts in Washington DC on 15 June 2004 (below).
Then tell us what you think about global warming.
AAAS All-star panel of climate experts, 15 June 2004
The scientists at Tuesday's climate conference acknowledged that
questions remain about climate-forecasting models. And, they said,
there will always be uncertainty about exactly what may happen and
precisely how various factors exert an influence. However, the
panelists also agreed that accurate predictions can be made over the
long term--and that greenhouse gases released as a result of human
activity are a major change agent. In fact, they said, the models are
more likely making conservative predictions rather than generous ones.
