Davos, Switzerland, Jan 24, SPA -- Former U.S. Vice President Al Gore and U2 frontman Bono offered measured praise Thursday for efforts in tackling climate change and global poverty, but warned the World Economic Forum that conditions were not improving as much as they could, AP reported. At an early-morning session that drew several hundred attendees, Gore warned that the world climate crisis was worsening.«We could take the whole session talking just about the new scientific evidence of the last few weeks and months,» said Gore, who shared last year's Nobel Peace Prize for his efforts to fight climate change, adding that the «climate crisis is significantly worse and unfolding more rapidly.»Bono, a vocal and high-profile advocate of reducing global poverty by providing debt relief to African nations and boosting efforts to treat and prevent AIDS, had similar comments to make on those issues.«There are now 2 million Africans on retroviral drugs and that is pretty astonishing,» Bono said. But, he added, efforts by the Group of Eight to pledge US$50 billion annually to eliminate poverty had not been met.--SPA www.spa.gov.sa/520636
