Those that try to deny climate change is occurring, or try to deny that humans are influencing climate change, point to changes in atmospheric composition, temperature, or other climate related variables that have occurred in the past. Climate change
idiots skeptics point out that temperature increases have occurred in the past, or that carbon dioxide increases in the atmosphere have occurred in the past. All true, but what they purposely do not address is the RATE of change that is occurring.
Atmospheric carbon dioxide levels have skyrocketed since the industrial revolution. In geologic time, it’s a blink of an eye, rising from 280 parts per million to nearly 400 ppm today. Over the past 500,000 years ago, carbon dioxide levels have naturally fluctuated…but only in a range between about 200 and 300 ppm. Atmospheric carbon dioxide levels today are likely the highest they’ve been in over 20 million years.
Again, however, climate change
idiots skeptics point out that atmospheric carbon dioxide rates were much higher in the far distant past. It’s true, as CO2 levels in the atmosphere were once much higher than they are even today. Besides the fact that the earth’s climate when CO2 levels were once 600 ppm or higher wouldn’t be very conducive to support today’s massive human population, the point that climate change idiots skeptics miss is the incredibly rapid rate of change over the past 200 years. It’s not just that today’s atmospheric CO2 levels are so historically high compared to the last 20 million years, it’s the astonishing rate of increase over just a 200 year period, a period that just happens to correspond perfectly to industrialization and the widespread use of fossil fuels.
Last week Science published a paper that talked about effects increased atmospheric CO2 are having on ocean acidity, stating that oceans today are acidifying at the fastest rate in at least 300 million years. As the authors of the paper note, “What we’re doing today really stands out in the geologic record.” It’s impossible to deny the correlation between human impacts on land-use change and use of fossil fuels, and the incredibly rapid increase in atmospheric CO2. This study on ocean acidification further strengthens the empirical evidence linking human activity with an unprecedented rate of change in atmospheric and ocean chemistry.
I’m sure climate change
idiots skeptics (and industry and politicians on the right who back them) are hard at work behind the scenes right now, trying to come up with a way to dispute the findings in this paper. From a scientific standpoint, you keep waiting for the day when the empirical evidence is so overwhelming that even climate change idiots skeptics can’t deny it any more. Hell, the evidence ALREADY is so overwhelming that any rational human being can’t deny it. Unfortunately we are either a) not dealing with rational human beings, or b) those in industry or those with political motivations for denying climate change KNOW it’s happening, but are purposely trying to distort the truth for their own political or economic gain. The latter is obviously true, as I have NO doubt that those in the fossil fuel industries KNOW climate change is occurring, and that we are to blame. I have NO doubt that politicians will PUBLICLY act like climate-change deniers, actually know the truth but are lying for political gain.
