The U.S. Senate in 1997 voted 97-0 to reject the Kyoto Treaty. In defiance of the U.S. Senate vote rejecting the treaty, both President Bill Clinton and Vice President Al Gore signed it. Had Al Gore been elected president last November, word was that he intended to push the treaty through regardless of the Senate disapproval..................that takes guts, something Dubya sorely lacks!

Looking at other things increasing in the future. Well if we aren't going to restrict population growth then I suppose we should look for way to increase the growth productivity of the land we farm. Or there will be lots of starving folks. Plant Growth Response to CO2 and Nitrogen (Grasses) -- Summary Perennial ryegrass (Lolium perenne L.) has been used as a model species in many experiments to help elucidate grassland responses to atmospheric CO2 enrichment and soil nitrogen availability. In the FACE study of Rogers et al. (1998), for example, plants exposed to 600 ppm CO2 exhibited a 35% increase in their photosynthetic rates without regard to soil nitrogen availability. However, when ryegrass was grown in plastic ventilated tunnels at twice-ambient concentrations of atmospheric CO2, the CO2-induced photosynthetic response was about 3-fold greater in a higher, as opposed to a lower, soil nitrogen regime (Casella and Soussana, 1997). Similarly, in an open-top chamber study conducted by Davey et al. (1999), it was reported that an atmospheric CO2 concentration of 700 ppm stimulated photosynthesis by 30% in this species when it was grown with moderate, but not low, soil nitrogen availability. Thus, CO2-induced photosynthetic stimulations in perennial ryegrass can be influenced by soil nitrogen content, with greater positive responses typically occurring under higher, as opposed to lower, soil nitrogen availability.
