"It ain't the heat, it's the humility." - Yogi Berra
Unfortunately, on the subject of global warming, humans have NO humility. We think we have advanced so far, yet we still think the universe revolves around humanity. We think our little greenhouse gases are going to end life on this planet.
Here is a thought for you Chicken Littles out there: If we detonated every single nuclear weapon we have, we would do more to hurt the planet than if we doubled our greenhouse gas emissions. On top of that, the planet WOULD recover from the nuclear devastation.
Arrogance, thy name is human.
