Bob Bennett made an important observation about how we seek the opinions of like-minded people, formerly in boarding houses, now more often from electronic sources (“A single world view warps our perception," Oct. 28). Nowhere is this partitioning of ideas more apparent than with the subject of climate change. Polls have repeatedly shown that the best predictor of one’s view on climate change is one’s political party.

With most political issues, one’s view is driven by opinion rather than science. But physics is no respecter of political party. The climate scenario is going to play out based only on what happens to our atmosphere.

Because of the gravity of what could occur with climate change, it behooves all of us to reflect on the source of our opinions on the matter. Democrats should ask themselves, do they have good reason to accept the consensus of climate scientists despite the contrary statements of opposing groups? Conversely, Republicans must ask, do they have good reason to accept the spin of special interest groups despite the worldwide near-unanimity of climate scientists?
