Climate change should be a matter of science, not politics. But only changes in public policy, which is often determined by political ideology, can reduce the human-caused warming that is threatening ecosystems around the globe.
In the end, governments, large and small, will be forced to confront the vast upheavals that climate change can bring if we don't act now to curb greenhouse-gas emissions.
That's why it's important that Salt Lake City is supporting a growing movement among cities to urge President Barack Obama and the Environmental Protection Agency to invoke the Clean Air Act to place limits on carbon emissions. The City Council and Mayor Ralph Becker collaborated on a resolution urging the federal agency to "swiftly employ and enforce" the act. Only Councilman Carlton Christensen voted against it.
