The following was a "letter to the editor" I submitted to a progressive magazine in response to articles on global warming:


In "American Psychosis" you point to the many people who acknowledge global warming, but do not change much, if anything about their destructive lifestyles, and in "Hot Air" talk about the point of view of skeptics and deniers.

I run a certified green hauling business. I modified my delivery truck to get 30mpg (from 15mpg) and run it on 100% biodiesel made from recycled veggie oil. I also work part time supporting people who bicycle to work (at a business which runs at a loss because our main service is free). I live in a 250square foot home and use less than $5 worth of electricity most months.
I also have some background in science, including degrees in earth science and biology, and generally track down sources for claims I read.

Having read arguments on both sides, I am not convinced that humans are significantly contributing to climate change. While I admit I haven't kept up with the latest research, I have yet to see several points addressed:

1 The climate naturally goes through cycles of extremes. The current climate reflects roughly where it is expected to be. Our methods of determining past temperatures are not precise enough to tell us the rate of change over small periods of time in the past, and so it is difficult to determine if what we see today is abnormal.
2 Geologic data suggests that in past periods of climate change, temperature has always changed first, with CO2 levels changing as a result of temperature change, not the other way around. This does not necessarily indicate it is what is happening this time, but it could account for what we are seeing.
3 Climate predictions are only as good as the models they are built on, which in turn are only as good as the computers that run them. We simply do not have computers powerful enough to accurately model something as complex as the earth's climate. Last I heard, in order to reduce complexity to a manageable level, most models omit details such as water vapor (arguably the single most important variable) all together.
4 Human caused climate change is frequently referred to (particularly in liberal media sources) as having "scientific consensus". According to Pew Research center 86% of scientists concur. While 86% is clearly an overwhelming majority in a democracy, in science 14% is too large a minority to simply ignore.

But here's the thing:
It doesn't make one bit of difference if humans are contributing to global warming or not.
Whether we are causing it or not, its happening (that doesn't take predictions, just measurements - its happening)
Therefor we should prepare for it.
Even more important: independent of global warming, our lifestyles are harming the ecology of our planet. Even if an individual feels no moral reason to care about life other than humanity, it is undeniable that we are totally dependent on the environment for our own survival.
