The debate over climate change is one of those strange human things. In a logical or analytic sense, there really shouldn’t be such an argument. If you see danger up ahead, you would naturally take action to avoid it, right?
Not so simple when dealing with humans.
Let’s take humanity out of the equation. Once you do, then it doesn’t matter which way the temperature goes on the Earth, or on any other planet. Planets don’t care either way. If you talk to the sun, it’s just pissed off it didn’t achieve black hole status and that it now has to wait for another ten or so billion Earth years before it gets another crack at it.
