The Bush administration released a climate change assessment on Thursday -- four years late and pushed forward by a court order -- that said human-induced global warming will likely lead to problems like droughts in the US West and stronger hurricanes. President George W. Bush's stance on the issue has evolved from denying climate science to acknowledging that global warming is happening. In March, watchdog groups said Bush's decision to intervene in setting air pollution standards was part of a pattern of meddling in environmental science.
