Nobel Peace Prize winner Al Gore said Monday he believes the next US president will shift the country's course on climate change and engage in global efforts to reduce carbon emissions. "The new president, whichever party wins the election, is likely to have to change the position on this climate crisis," Gore told The Associated Press in an interview before the Nobel Prize ceremony. "I do believe the US, soon, is to have a more constructive role." Gore said it was not too late for the administration of President George W. Bush to join efforts to draft a new global treaty limiting greenhouse gas emissions. "I have urged President Bush and his administration to be part of the world community's effort to solve this crisis," Gore said. "I hope they will change their position."
