The climate has always been changing.
The climate has been changing since the Earth began.
We have warm periods and cool periods. That climate.
Likely you have heard one of these arguments or some variation before. Look at any conversation about climate change and you will see at least some man-made climate change denier using it. It’s hard to even know exactly what they mean by the argument. I’m not even sure what argumentation fallacy to call it. Perhaps it’s just a non sequitur, but let’s try to break it down.
First, let’s start simply. If such people using the argument are trying to claim that what we are seeing is natural climate change, then they are misstating the argument. They should simply say. Yes the climate is changing, but there is insufficient evidence that man is the cause. I mean that’s not true, of course, but it would be an argument. Just one in which the person making the argument hasn’t adequately analyzed the evidence. The other implication here is that scientists in this field either don’t know that the climate changes naturally or that they don’t know what causes climate to change naturally, but just decided to come to a massive consensus across multiple scientific disciplines that it’s happening. This is also is ridiculous.
However, the way this argument is phrased it seems that the argument that is really being made here by those who use it, is that they think one of two things (or perhaps both):
- Since climate changes naturally it can’t change because of human influence.
- Since climate changes naturally there is nothing that can be done about it.
Let’s deal with the second argument first. And let’s even go so far as to say that the person is right. What we are seeing is just natural. Given the rate the temperature is warming this is cause for alarm, even if it is natural. It threatens many human populations, will increase drought frequency, extreme precipitation events, national security issues, species extinction, rapid sea level rise, etc. If this is happening naturally, then why shouldn’t we be trying to do something about it? If a naturally started forest fire threatens people’s homes, should we not put it out. Should we not build homes more securely to mitigate damage from hurricanes? We do so many things to try to mitigate and prevent damage and deaths from natural disasters, it seems ridiculous to me to make any such claim that natural climate change that threatens large populations of people and ecosystems worldwide isn’t something that we should be trying to do something about.
The first argument takes even less effort to counter. My favorite example is to use evolution, which of course happens naturally, but practically all farming, horse and dog breeding happens through man-made selection in order to increase food nutrition and create your favorite breeds of dogs and horses. Taken to the extreme we could simply say that death is a natural process, thus there is no such thing as murder. Or since death is a natural process there is no sense in trying to cure people of cancer.
Overall it is difficult to understand why this is such a common argument, and why this seems to be the final argument for so many to dismiss man-made climate change as a non-issue. Feel free to share this post with folks you know who have made this argument.
