[Blog Action Day] Climate Change presupposes that there is some sort of change coming in the status quo of climate not-change. And to a large extent, that is the case. I studied a variety of subjects but mostly circled around the most recent 25,000 years of this planet’s history. Lots of climate change there in those 25 millennia.
One thing is certain, and that is that climate change means changes in our world. Big changes. My experience covers things like woodlands becoming grasslands, and deserts emerging where herds of animals once grazed. Coastlines changed drastically as ocean levels went down when much of the northern hemisphere was covered with as much as 3 kilometers of ice.
When the average temperature rose again, millions of square miles of coast where animals (and humans) doubtlessly lived were again submerged as all that ice melted into the world’s oceans.
Relatives of ours, Neanderthals, disappeared. Lots of very conspicuous animals — huge grazers like mammoth and mastodons, woolly rhinoceros, giant ground sloths, and the predators that were dependent on them like saber-tooth cats, dire wolves, other cats and canine relatives — became extinct.
This particular episode will likely be unsurpassed since any in the last 7,000 years. It will be interesting, but not in a good way. More like the Chinese proverb, “May you live in interesting times.”
Perhaps we will go extinct
