What’s clear is that nothing escapes our influence. Nothing is untrammeled. The human signature has been scribbled across the planet with absolute comprehensiveness. So let’s not argue that we shouldn’t tamper with the Earth. We’ve already tampered with it. We’re tampering with it right now. Every time we dress, every time we drive, every time we eat, every time we plug something in, or touch a thermostat, or buy a toy, or send an email, we are geoengineering.
