LONGMONT, Colo.—Interior Secretary Ken Salazar is talking climate change on a trip to a solar energy factory in his home state of Colorado.

While health care dominates debate in Washington, President Barack Obama’s top environmental and energy officials continue to urge the Senate to move on legislation to tackle global warming.

Salazar will talk about the climate bill pending in the Senate on a trip to the Abound Solar plant in Longmont on Tuesday.

Earlier this summer the House narrowly voted to impose the first limits on greenhouse gases, eventually leading to an 80 percent reduction by mid-century by putting a price on each ton of climate-altering pollution.
