What the Science Says

"There’s lots of layers to it. But at least as to any potential man-made contribution to it, it’s fair to say the science is in dispute."

That human CO2 is causing global warming is known with high certainty & confirmed by observations.

"The weight of the evidence is that most of it, maybe all of it, is because of natural causes."

Multiple sets of independent observations find a human fingerprint on climate change.

"The climate's always changing. So there's no doubt that climate changes. The real question is why is it changing and how much of it if any is attributable to human behaviour."

Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing.

"The weight of the science indicates that if there's any human behaviour involved, it's a modest amount."

Theory, models and direct measurement confirm CO2 is currently the main driver of climate change.

"I think climate change occurs but I think the bulk of it is mostly natural historic trends in the climate"

Multiple sets of independent observations find a human fingerprint on climate change.

"You can argue, you know, that the world is the globe is warming as it always has for natural reasons but I think the way indicates, at least some of it, you can argue whether it’s 1/2% or something more substantial, you know, is caused by human behavior. "
