The Case for Global Warming, Part 2: How We Know It's Us

In Part 1 of “The Case for Global Warming,” I presented an overview of the evidence that the Earth is indeed warming, and at a rate unprecedented in over 10,000 years. Today, I cover the evidence that we are its primary cause, and how, as a species, we manage to accomplish such a task.

There is no doubt that the globe is getting hotter, and at a brisk pace. But what is the underlying cause? The evidence points unambiguously towards human interference. Nonetheless, how are we, weak, half-naked apes that we are, able to affect climate on a global scale? Isn’t it a little arrogant to think we have so much power?

Seeing the effect we’ve had on the world through industry—in particular, the burning of fossil fuels—can be depressing. With the world’s temperature increasing faster than it has in millennia, and our continued, voracious consumption of our rapidly depleting fossil fuels aiding that rise, despair seems the natural recourse. Nonetheless, countermeasures exist, and to my surprise one of them—the use of biodiesels as a fuel source—is gaining traction.
