Global What?

I know I'm beating a patch of grass where a dead horse used to be, but there is news from the world of dendrochronology: climate changes. It gets warm, it gets cold, but what it never does is stay the same. It has been warmer is historic times (Medieval Warm Period) than anything the warming alarmists are predicting and the world's forests didn't burst into flame and the polar bears seem to have come through just fine. But the best news is that even the Medieval Warm Period pales next to the 3,000-year-plus heat wave called the Holocene Climate Optimum that ran from 5500 to 3300 BC. If the world survived that, I'm sure it will do fine during the incredibly minor up-tick during this century as temperatures return to normal after the Little Ice Age.

OK, OK; I'll shut up now.
