denialists (like
Jim Inhofe) will build a snowman and say, "What climate change? Nyuck, nyunk." People are conflating climate with weather. Climate is an average of what has happened over a period of years, decades or even centuries.
Scientists can't definitively say that Hurricane Sandy was caused by global warming any more than doctors say that one particular home run by Barry Bonds was as a result of steroid use. What both can say is that the likelihood of either is much increased by their respective underlying conditions.
I see little difference between Creationists who think the Earth is 6,000 years old and global warming deniers who think that humans aren't responsible for changing the climate by burning millions of years worth of sequestered carbon in less than three centuries. I'd really like to know how releasing gigatons of carbon into the atmosphere in the geologic blink of an eye doesn't have an effect. On a separate note,
humans have altered the nitrogen cycle through the Haber-Bosch process by removing nitrogen from the atmosphere and put it into the biosphere. That amount of nitrogen in the biosphere hadn't changed in over a hundred million years.
