A Quote by Freeman Dyson
Climate change is part of the normal order of things, and we know it was happening before humans came.

There is no question that climate change is happening; the only arguable point is what part humans are playing in it.
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.
If you look at the polling around climate change in this country before 'Sandy', that was kind of the low point in terms of Americans believing that climate change was real and that humans were causing it.
Many scales of climate change are in fact natural, from the slow tectonic scale, to the fast changes embedded within glacial and interglacial times, to the even more dramatic changes that characterize a switch from glacial to interglacial. So why worry about global warming, which is just one more scale of climate change? The problem is that global warming is essentially off the scale of normal in two ways: the rate at which this climate change is taking place, and how different the "new" climate is compared to what came before.
Climate change is happening, and humans are significant contributors, and that raises some really important policy questions.
Climate has always changed. It always has and always will. Sea level has always changed. Ice sheets come and go. Life always changes. Extinctions of life are normal. Planet Earth is dynamic and evolving. Climate changes are cyclical and random. Through the eyes of a geologist, I would be really concerned if there were no change to Earth over time. In the light of large rapid natural climate changes, just how much do humans really change climate?
Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.
We can't take climate change and put it on the back burner. If we don't address climate change, we won't be around as humans.
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.
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.
It's very hard to track down what's real and what's not real. We haven't absorbed what climate change is doing. Because whether people associate it or not, fear of immigration is completely related to climate change, because the mass migrations that are happening, the war in Syria, all of these structural human migrations are related to climate change.
I believe humankind has looked at Climate Change in that same way: as if it were a fiction, happening to someone else’s planet, as if pretending that Climate Change wasn’t real would somehow make it go away.
There is no doubt in my mind that the literature on climate change overwhelmingly supports the hypothesis that climate change is caused by humans. I have very little reason to doubt that the consensus is indeed correct.
Any objective look at what science has to say about climate change ought to be sufficient to persuade reasonable people that the climate is changing and that humans are responsible for a substantial part of that - and that these changes are doing harm and will continue to do more harm unless we start to reduce our emissions.
Of course climate changes. Many changes are due to factors over which humans have no control, such as winds, ocean currents, and sun activity. But the liberals want us to believe that climate change is also caused by gases expelled when humans burn so-called fossil fuels.
The question is not, "Is climate change happening?" Nor is the question, "Is climate change man-made?" Rather, we need to realize it?s already here, and start asking, "What are we going to do about it?"
