Despite the international scientific community's consensus on climate change, a small number of critics continue to deny that climate change exists or that humans are causing it. Widely known as climate change "skeptics" or "deniers," these individuals are generally not climate scientists and do not debate the science with the climate scientists.
I don't know the science behind climate change. I can't say one way or another what is the direct impact, whether it's man-made or not.
On the science of global climate change, I'm an agnostic. I've seen Al Gore's movie, and I've read reports from the Intergovernmental Panel on Climate Change. I've also listened to the 'skeptics.' I don't know who's right.
Climate change is real. Climate change is being substantially increased by humans and the carbon we put into the atmosphere. And it appears to be speeding up. If science has made any mistakes, science has been underestimating it.
I’ve often said that global climate change is an issue where no one has the luxury of being “half-pregnant.” You either are or you aren’t. And so it is with climate change. You either understand and accept the science – or you don’t. Folks this isn’t a cafeteria where you can pick and choose and accept the science that tells us what is happening, but then reject the science that warns us what will happen.
This is not rocket science - climate science is very simple. A 12-year-old could probably understand this subject [of climate change].
Climate change - for so long an abstract concern for an academic few - is no longer so abstract. Even the Bush administration's Climate Change Science Programme reports 'clear evidence of human influences on the climate system.'
I don't believe ... global warming is real. Do we have climate change? Yes. Is it a crisis? No. ... Because the science, the real science, doesn't say that we have any major crisis or threat when it comes to climate change.
The U.S. has fallen well behind Europe in recognizing climate change and the implications of climate change.
The argument [behind climate change] is absolute crap. However, the politics of this are tough for us. Eighty per cent of people believe climate change is a real and present danger.
I don't know the science behind climate change. I can't say one way or another what is the direct impact, whether it's man-made or not. I've heard arguments from both sides, but I do believe in protecting our environment, but without the job killing regulations that are coming out of the Environmental Protection Agency.
I come back to the science that is in it to reduce our dependence on foreign oil and climate change. It's about science, science, science and science, innovation, as we rebuild America, create jobs, invest in our people and turn this economy around.
Climate change: I say the debate is over. We know the science, we see the threat and we know that the time for action is now
I am, as you know, hugely unconvinced by the so-called settled science on climate change.
Scientists tend to focus on what they don't know more than what they do know. And there are a lot of things we still don't know about the climate. But we know the difference between climate variability and climate change, and right now the amount of carbon in the atmosphere is well outside the variability pattern - and that's quite quantifiable.
Science is the only news. When you scan a news portal or magazine, all the human interest stuff is the same old he-said-she-said, the politics and economics the same cyclical dramas, the fashions a pathetic illusion of newness; even the technology is predictable if you know the science behind it. Human nature doesn't change much; science does, and the change accrues, altering the world irreversibly
