I grew up in the fifties, shitless with fear over the expected descent of the next Ice Age.
I plowed out my bumpy fields of uneasiness with recreational drug use in the sixties, the pursuit of fun and money in the seventies and eighties, and then children in the nineties till now. My glacial adversary, however, bided its time and has reemerged as global warming.
Ice Ages, plural because there are many of them in Earth’s history, seem to have their very own periods of warming during them, known as interglacial periods. We are inside this little pocket of warmth right now.
According to Bill Bryson, “Even less well understood are the cycles of warm weather within ice ages, known as interglacial periods. It is unnerving to think that all of recorded human history, from the development of farming, the creation of towns, the rise of mathematics, writing, science, and all the rest, has taken place within the current interglacial period of mild weather conditions. Previous interglacial periods have lasted as little as 8,000 years. Our present interglacial period has already passed 10,000 years. ”
I knew it!
