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.

When God made the planet, he made the plants, he made the animals, he made the Sun and the Moon, and he made us, and we're all interconnected, and when we disregard, disrespect, or damage any part of it, we do violence against creation.

Many people have the impression that there is significant scientific disagreement about global climate change. It's time to lay that misapprehension to rest. There is a scientific consensus on the fact that Earth's climate is heating up and human activities are part of the reason. We need to stop repeating nonsense about the uncertainty of global warming and start talking seriously about the right approach to address it.

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

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

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?

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.
