SALT LAKE CITY – Utah lawmakers are getting competing views on climate change, one emphasizing the vast scientific consensus about warming trends and humanity's influence and another raising doubts about the root causes.
At a standing-room-only hearing at the Capitol Wednesday, the Public Utilities and Technology Interim Committee heard 90 minutes of testimony on climate change.
University of Utah scientist James Steenburgh, who led a state science panel on the expected effects of global warming in Utah, emphasized that temperatures are gradually rising and people are very likely to blame.

Lawmakers held the hearing as they follow Congress' consideration of carbon cap and trade legislation.
