Recent data and research supports the importance of natural climate variability and calls into question the conclusion that humans are the dominant cause of recent climate change.
'Years of Living Dangerously' is a wonderful opportunity to reach a lot of people with the story and importance of climate change in our lives; in recent history, there's no bigger threat to the quality of human life than what is taking place right now in respect of climate change.
Our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change. The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year [2011] can each be attributed to climate change. The odds that natural variability created these extremes are minuscule, vanishingly small. To count on those odds would be like quitting your job and playing the lottery every morning to pay the bills.
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.
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 think the whole human-induced greenhouse gas thing is a red herring... . I see climate change as due to the ocean circulation pattern. I see this as a major cause of climate change... . These are natural processes. We shouldn't blame them on humans and CO2.
The results of recent research on the impacts of climate change dramatically weaken the case for expensive, near-term abatement programs.
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.
Sensible policies on global warming should weight the costs of slowing climate change against the benefits of slower climate change. Ironically, recent policy initiatives, such as the Kyoto Protocol of 1997, have been introduced without any attempt to link the emissions controls with the benefits of the lower emissions.
...the Climate Research Unit of the University of East Anglia apparently cherry-picked Russian climate data.
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?
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?"
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.
Humans are not responsible for climate change in the way some of people are trying to make us believe, for the following reason: I believe the climate is changing because there's never been a moment where the climate is not changing.
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.
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.
Why are the people who are most alarmist about climate change so opposed to the technologies that are solving it? One possibility is that they truly believe nuclear and natural gas are as dangerous as climate change.
