Scientists should continue doing what they've always done, which is to understand the Earth as well as they can.

It really is a very radical call ... to reject materialism as our central value and to think about the sanctity of life and what that really means if we take it seriously.

Why would scientists dedicated to uncovering the truth about the natural world deliberately misrepresent the work of their own colleagues? Why would they spread accusations with no basis? Why would they refuse to correct their arguments once they had been shown to be incorrect? And why did the press continue to quote them, year after year, even as their claims were shown, one after another, to be false?

What to do about climate change is political, it's social, and it's moral, which is one of the reasons the scientific community reached out to the Pope, to ask for his involvement in this issue.

Yet again, unscientific claims were being circulated broadly, but the scientists' refutation of them was published where only fellow scientists would see it.

There's real economic costs to climate change - So, Superstorm Sandy led to billions of dollars in damages. The fires out in the west, 70 million dollars a day are being spent in fighting fires that have clearly been exacerbated by drought and climate change. So, people have pointed out the true dollars and cents cost of inaction on climate change.

Scientists are scientists. They're not really in a position to speak clearly on the moral dimensions, and they're not really comfortable doing that.
