A Quote by John F. Kerry

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.
It is baffling, I must say, that in our modern world we have such blind trust in science and technology that we all accept what science tells us about everything - until, that is, it comes to climate science.
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.
This is not rocket science - climate science is very simple. A 12-year-old could probably understand this subject [of climate change].
If what the science tells us about climate change is correct, then unabated it will result in catastrophic consequences for our world.
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.
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.
See, I am the mayor of Realville, and science is not up to a vote. It either is or isn't. Whatever it is, it is or isn't, but it's not up to a vote. Global warming doesn't exist because a "consequences of scientists" agree. Manmade global warming either is happening or it isn't, but it isn't up to a vote. But it is being presented to you as a consequences of scientists. Therefore, the science is not settled. Besides that, we all know that it's a hoax now. It's just some people don't want to accept that, but it is.
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.
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 scientists think of nothing but climate and then express their concerns in terms of constructs such as global mean surface temperature. But we live in a world in which all sorts of change is happening all the time, and the only way to understand what climate change will bring is to tell stories about how it manifests in people's lives.
I'm a geophysicist who has conducted and published climate studies in top-rank scientific journals. My perspective on Mr. Inhofe and the issue of global warming is informed not only by my knowledge of climate science but also by my studies of the history and philosophy of science.
Oceans need more attention because climate change IS an ocean issue. Our oceans will be the first victim, and sea life will suffer dramatically. Detailed proof is hard in ocean science, but I think we're already seeing big ocean changes caused by climate change, such as starvation of whales, seabirds, and other animals off the coast US west coast.
I’ve starred in a lot of science fiction movies and, let me tell you something, climate change is not science fiction, this is a battle in the real world, it is impacting us right now.
We have to overthrow the idea that it's a diversion from 'real' work when scientists conduct high-quality research in the open. Publicly funded science should be open science. Improving the way that science is done means speeding us along in curing cancer, solving the problem of climate change and launching humanity permanently into space.
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.'
Climate Change is a national security issue. We found that climate instability will lead to instability in geopolitics and impact American military operations around the world. People are saying they want to be perfectly convinced about climate science projections. But speaking as a soldier, we never have 100 percent certainty. If you wait until you have 100 percent certainty, something bad is going to happen on the battlefield.
