G.O.P. Jump on the Global Warming Bandwagon

After Al Gore was awarded the Nobel Peace Prize Friday for his "work highlighting the treat posed by climate change," many of the Republican presidential contenders have integrated their views and how they would handle the issue into their speeches. Senator McCain is calling for the capping of gas emissions that are linked to global warming and higher fuel economy standards. On the other hand, Giuliani and Romney are emphasizing a push toward clean coal and other alternative energy sources. However, they all agree on one thing, that nuclear power should be greatly expanded.
