OKLAHOMA CITY (AP) - Sen. Jim Inhofe says he opposes a government proposal to reduce greenhouse gas emissions by 17 percent by 2020.

The Oklahoma Republican says he plans to travel to a climate conference in Europe next week to tell participants the proposal has little support in the U.S. Senate.

The Environmental Protection Agency has said scientific evidence shows greenhouse gases threaten public health and that the pollutants should be reduced. But Inhofe says he believes emissions, mainly carbon dioxide from burning fossil fuels, have little effect on the climate.

Inhofe has called for an investigation into allegations that some scientists manipulated data to provide proof of global warming. A climate change skeptic, Inhofe says e-mails leaked from climate scientists indicate researchers suppressed data.
