Despite the evidence, there remains a united group of people who have labeled global warming as nothing more than a “green scam”, claiming that the entire movement is based on uncertainty. Let’s examine some of the more common opposition to global warming.
“The global temperature is supposed to rise and fall; it’s been changing throughout history.”
In some respects, critics who make this claim are right. Natural forces have caused climate to change many
times throughout history. For example, some more recent science suggests that dinosaur flatulence actually contributed to an increase in global temperature, way back when the dinosaurs actually ran the Earth.
However, that does not mean that climate change cannot be caused by humans. While climate has changed
before, and significantly in some respects—ice ages and other extreme climate conditions—never before have so many signs pointed towards the Earth warming due to anthropogenic causes. Scientists think there is no other answer.
“Not all scientists believe in global warming.”
This claim, believe it or not, is also true. What skeptics leave out, however, is that the scientists that don’t believe in global warming are the overwhelming minority. In fact, a 2004 study shows that not one published, peer-reviewed paper between 1993 and 2003 denied the claim that global warming is happening as a result of human action. Ninety-seven percent of climatologists believe that human activity is a main agent of climate change. So, while not 100% of experts agree, it’s pretty darn close.
“Even if it is changing, we can adapt.”
Again, there is some truth to this claim. Living organisms, humans included, have been known to adapt to changing environments. However, these adaptations have never been forced to take place on such a short time scale. The biology behind this assertion is untested, the speaker would most likely not be willing to test this claim on his or herself.
“Carbon dioxide is not a pollutant; organisms existed for centuries with much higher CO2 levels than we have now.”
This claim is also entirely true. What skeptics conveniently forget to realize is that humans were not one of the organisms that existed with these higher carbon dioxide levels. In fact, the majority of organisms that we know today were not in existence back then. The earth was largely inhabited by microorganisms and primitive plants, organisms that use carbon dioxide in respiration. Also, at the time in question, the sun was considerably cooler. Therefore, the consequence of the greenhouse effect that resulted from the higher carbon dioxide levels was much less pronounced.
There are hundreds of claims that skeptics make against climate change. The previous claims are just
some of the more popular ones. While the claims of global warming critics are not outlandish, they tend to crumble upon further inspection. One can only hope that the true answer is uncovered and more wholly approved of before it’s too
