Let’s be specific about global climate change
People, let’s face it. Global warming is happening.
That’s a trickier matter. The earth has been much colder, and much warmer, than it currently is. The razor-thin sample of time which we refer to as “recorded history” is hardly a big enough sample to determine what the earth’s “normal” climate is. We just know what we are used to.
The ice at the north and south poles is melting. Asking whether or not it is linked to global climate change is fatuous. YES, the climate is changing, that’s why it is unseasonably cold in Seattle right now, and it is probably why weather patterns have been so disrupted for the last 15 years (El Nino? Katrina? Remember those?).
The real questions are: how much of what we are seeing is being caused by human beings, would this be happening without us, and is there anything we can do to stop it?
