Researchers mine Twitter to reveal Congress’ ideological divide on climate change

Senate Democ­rats are three times more likely to follow science-​​related Twitter accounts than their Repub­lican peers, according to a new study led by Northeastern’s Brian Hel­muth. The research shows the growing divide between par­ties on the issue of cli­mate change, but also pro­vides hope, says Hel­muth, pointing to indi­vid­uals who cross the aisle and bridge the gap.

Their find­ings rep­re­sent an ini­tial step in con­structing models to detect trouble before it’s too late.
