Minnesota House members revealed Wednesday whether they believe humans are causing climate change.

It broke largely along party lines: 79 lawmakers, including all 75 Democrats, voted yes, and 50 Republicans voted no. Five Republicans did not vote.

They voted on this sentence:

“The legislature finds and declares that greenhouse gas emissions resulting from human activities are a key cause of climate change.”

That was all it was. No money, no regulations.

State Rep. Frank Hornstein, DFL-Minneapolis, proposed adding the declaration to a much larger bill covering jobs, economic development, energy, climate and telecommunications policy and finance.

Several Republicans spoke against the vote — and the notion of human-caused climate change.

“Human activities are not the cause of climate change,” said state Rep. Eric Lucero, R-Dayton, in a speech on the House floor.

He repeated the sentence at least twice and continued, implying, apparently, that because the Earth has been both colder and hotter in the past, climate science is flawed.

“We were at one point in an ice age,” he said, adding later, “This is fake.”

HOW THEY VOTED

Every Democrat voted in favor of the declaration.

The following Republicans joined them: Reps. Pat Garafalo, R-Farmington; Tony Jurgens, R-Cottage Grove; Dean Urdahl, R-Grove City; and Nolan West, R-Blaine.

No vote was recorded for the following members: Greg Boe, R-Chaska; Ron Kresha, R-Little Falls; Joe McDonald, R-Delano; Nels Pierson, R-Stewartville; and Nick Zerwas, R-Elk River.

Here’s the full record:

THE SCIENCE

According to NASA: “Most climate scientists agree the main cause of the current global warming trend is human expansion of the “greenhouse effect” — warming that results when the atmosphere traps heat radiating from Earth toward space.”

The United Nation’s Intergovernmental Panel on Climate Change concluded that human-caused greenhouse gas emissions and other human causes are “extremely likely to have been the dominant cause of the observed warming since the mid-20th century.” (emphasis original)
