It's not Used... It's Pre-Owned!

This is why people who understand the fine art of marketing now use the term Climate Change versus Global Warming

Arctic chill stretches coast to coast

When record high temps are being reported, it's due to global warming.
When record low temps are being reported, it's due to global warming, er... climate change.

I think Time Magazine got it right the first time in 1974...

"Whatever the cause of the cooling trend, its effects could be extremely serious, if not catastrophic. Scientists figure that only a 1% decrease in the amount of sunlight hitting the earth's surface could tip the climatic balance, and cool the planet enough to send it sliding down the road to another ice age within only a few hundred years."

Question: If scientific research evolves and later contradicts previously held positions on a particular subject, would we be aware of it? Will there be some big announcement? Or is it like the whole "tree in the forest thing?" In other words, if they don't widely report contradicting evidence does it mean it's only because it's not true?

To be honest, I'd prefer a warming trend over a cooling trend. I'm from California, we can't take much...
