“Climate Change is caused by human emissions; it moves faster or slower partly in response to our rate of emissions, but also because of natural "tipping points" that make the planet take things in its own hands. So, for example, during one of the last great climactic shifts, the planet may have gone from being fairly warm to an ice age in less than ten years; and then the ice age may have ended in a single season! These things are very hard to model, but projections for the future that imagine Climate Change will occur in a gradual and orderly fashion are probably wrong.”

“f we view climate changes as our enemy we will always be defeated, for climate will always change. Natural climate change is frequent, often extreme, and sometimes rapid. Industrial CO2 is a real problem just as you have heard, but it’s only a fragment of the whole story of climate. In other words, I’m not a global warming denier – I want to add to the discussion of climate change from the point of view of geology and natural change. What may matter most is not our carbon policies, but whether we invest in adaptive strategies that can serve us well when change inevitably arrives on our doorstep.”

“There are many things in the deep waters; and seas and lands may change. And it is not our part here to take thought only for a season, or for a few lives of Men, or for a passing age of the world. We should seek a final end of this menace, even if we do not hope to make one.”

“By eating meat we share the responsibility of climate change, the destruction of our forests, and the poisoning of our air and water. The simple act of becoming a vegetarian will make a difference in the health of our planet.”

“He shrugged. “Yeah, but I like riding my bike. It helps with the ozone… and stuff.” “You’re trying to avoid leaving a carbon footprint? And here I thoughtbicycles were just for tree-hugging hippie heterosexuals.” He eyed me seriously. “We all have to do our part to help avoid nocturnal emissions. The planet needs us.” I stared at him. “The planet needs us to avoid nocturnal emissions?” He nodded. “Nocturnal emissions are the number one cause for the hole in the ozone.”

“Even as I speak, the very last polar bear may be dying of hunger on account of climate change, on account of us. And I sure miss the polar bears. Their babies are so warm and cuddly and trusting, just like ours.”
