I think it's a lot easier to accept man-made global warming when you realize how significant humans are on a global scale. There's two numbers that blow my mind every time I think about them. The first is the energy produced by the radioactive decay at the fiery core of the Earth: 45 terawatts. That power is enough to move the continents around the globe. The second is the energy produced by human industry -- all of our coal plants, oil burned, nuclear power, solar & wind, the whole 9 yards: 16 terawatts. That's 1/3 the power generated by the entire rest of the Earth, down to the core, and it's growing: if it grows at the same rate as it has historically, in 25 or 30 years we'll surpass the core entirely. Humans aren't just insignificant specks on the surface of the Earth, we're major players, comparable to its fiery core. Knowing that, is it so surprising we can affect the climate significantly?
