Why I’m a Climate Change Skeptic

The question of whether or not human beings are changing the climate is a critical issue in today’s world. If it is indeed true, then steps must be taken to reduce human impact on climate. If is not true, but is a hoax being perpetrated for political gain, then it needs to be refuted and put behind us.

ClimateChangePersonally, I am highly skeptical that human activity is significantly changing the climate, because I can’t find any actual evidence to support the theory. What I find is a lot of spin. I see claims without any supporting evidence. I see politicians appealing to global warming as the cause for the rise of ISIS. I see laws being enacted to reduce our “carbon footprint” without any evidence to support the need to do so. I see pseudo-science being sold as fact to support political ideology. What I can’t seem to find is actual observational evidence that man-made global warming actually exists.

In order to establish that man-made global warming is fact, two questions must be answered: Is the climate changing? And if so, is humanity responsible?

Is the climate changing? Yes, the climate is changing, but, that’s what climate does. There have been warming and cooling trends throughout recorded history, as well as evidence that climate has always changed. The question is, is there any statistically significant difference between recent changes in climate and changes that have occurred in the past? From what I have been able to find, there is no credible evidence that the climate changes today are any greater than climate changes in the past; in fact, from what I can tell, recent changes have been very minor when compared to historical data.

polarbearAre humans responsible for the changes we see? Again, I can’t seem to find any actual evidence supporting the claim that human activity significantly changes climate. There is evidence that carbon dioxide content in the atmosphere is slightly higher today than it was in the recent past. What’s missing is direct evidence showing that this slight rise is due to human activity rather than natural causes, and that this rise has had any effect on climate. The evidence I find is that water vapor is the greenhouse gas most responsible for climate variation, not carbon dioxide, and that variations in solar intensity account for the majority of changes in climate.

Here’s a challenge to those who believe man-made climate change is real:

  1. Show me the evidence that recent changes in climate show a statistically significant difference from historical data.
  2. Show me the evidence that humans are responsible for these changes, ruling out all natural causes.

Don’t show me scientific opinions, political spin, or pictures of polar bears. Show me the empirical evidence. Don’t show me biased interpretations of the evidence, and don’t show me polls telling me what people believe. Show me the actual facts.
