A Quote by Ian Plimer

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?
It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.
Here on Earth, we're exposed to asteroids hitting the Earth, eventual changes in the Sun, changes in the Earth's climate, things we're doing to the Earth's climate. If we want to survive, we need to become a multi-planet species. That's further down the road, but the first wave is going to be the explorers.
We're facing enormous changes in our planetary life, with climate change and the adaptations that all natural systems are going to have to make to these climate changes, and so it's extremely important to bear witness to what's happening.
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.
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.
Climate change, habitat destruction, extinctions - the Earth has seen it all before, thousands of years ago. And humans may have been partly to blame for many of those changes in nature, too.
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.
Climate changes are caused by solar radiation and other natural phenomena, so I don't worry one bit about that. Nothing we do can change anything in the climate.
Climates always change. The question is, how are we going to adapt to climate change? Now, it may be true that we are accelerating it inadvertently by messing with our atmosphere, but regardless of that, the climate will change.
Never denied climate change. It has always changed and always will.
Global climate change is real and we have a limited time to change our behavior or live with the consequences. We can all help by making small changes in our lives to letting our voice be heard by our governing bodies. As has always been the case in this country, if the people demand change, it will come.
The climate is changing; I don't think you can deny that. But climate has always changed.
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 am afraid that I do not hold with the theory of 'global warming' - there will always be climate change....Big thing here is - do we know what we are doing that is bringing about climate change? At present the answer to this is NO.
The climate has always changed - after all, we've had numerous ice ages without human influence - but human activity has undoubtedly exacerbated Earth's natural trends beyond its capacity to adjust.
Sure there's a percentage of people who are like, "It snowed in May. I don't believe in climate change." Well, that's crazy, but that's always gonna be the case. I suppose if climate change happens much faster than even the dire experts predict, then I suppose opinions will change.
