“Constituents care about these issues,” Gohringer said in a telephone interview. “Calling these members out starts that dialogue.”

{mosads}The LCV said in a Monday statement that the lawmakers’ “extreme positions put them at odds with their own constituents” by denying the science regarding climate change.

While an overwhelming consensus of scientists agree human activity contributes to greenhouse gas emissions that drive climate change, many Republicans are skeptical of or deny that connection.

The new LCV endeavor, news of which surfaced last week, builds on recent polling the group commissioned that showed young voters are more likely to support a candidate that believes action is required to address climate change.

That data has generated some momentum for the new advertising campaign, Gohringer said. He said the campaign would be one in a series of efforts regarding climate change.

The push comes on the heels of a climate agenda President Obama rolled out in June, which earned plaudits from the environmental community, public health organizations, left-leaning groups and most Democrats in Congress.

But Republicans, industry and some centrist Democrats have pushed back against the plan, which relies heavily on regulations. They’ve taken issue with Obama’s call for greenhouse gas emissions standards for new and existing power plants, saying that move would damage the economy.
