Republican lawmakers in the Trump era are talking about climate change far less than they used to, while Democratic mentions have spiked to new highs, according to an analysis by public affairs software company Quorum.

The big picture: There's always been a divide between Republicans and Democrats on the issue, but this data — measured by the number of floor statements, press releases and social media posts that mentioned climate change — shows that the chasm is growing. And it's happening as new scientific reports and extreme weather events are drawing new attention to the issue.

Likely reasons GOP acknowledgement is declining:

Republicans have less incentive to address the topic, partly due to the position President Trump has taken. With Trump's refusals to accept the findings of recent climate reports — even from his own administration — he has moved the party further from the scientific consensus and has taken away cover for members who want to address the issue.

Forced into immediate answers, Republicans have retreated where they might otherwise acknowledge the science at a more gradual pace.
