When the dinosaurs were around CO2 concentrations were up around 3000ppm. @p{par} I'm not saying there will be no effects of global warming@p{--} I am claiming that we, and mother nature, will adapt. @p{par} We could argue about whether it would be less expensive or better to change our behavior now rather than just adapt later@p{--} last I looked, adapting by (for example) moving inland and abandoning low- lying cities and countries was estimated to be cheaper than spending money to reduce CO2 emissions.
