Here is a slightly edited version of a post I’ve used every year at this time for several years running. The link for my original source for the list isn’t working. Here is another.
Hallowe’en is coming up. A rollicking, morbid carnival, a celebration of the mortal flesh through sugar, alcohol, sex, and fake blood (if you don’t believe me about the sex, look at the women’s costumes available in stores), a blurring of identity and the thrill of things that go bump in the night.
I could write about the impact of the holiday on global warming, but that’s been done. I could write a scary story about our possible future, but that’s been done, too.
But, basically, I’m not all that interested in Hallowe’en anymore. I’ve grown out of trick-or-treat and I’m not frightened by blood, fake or otherwise. I’m more interested in the older traditions of taking a day to honor and remember the dead. This is therefore a Day of the Dead post, a Samhain post. I want to mark and honor the dead of climate change–not as a scare tactic or a self-flagellation of guilt, but simply as an act of witness. Because it is the right thing to do.
There are several possible ways to go with this. I could focus on individuals who have died of climate change, but linking global warming to particular deaths is very difficult. The result would also be too similar to my post comparing the mortality rates of climate change and Ebola. Instead, I want to honor whole species that have died. I’ve often thought that reading a list of recently extinct species names, the way the names of individuals lost to some accident or disaster are sometimes read, would be a powerful way to add an ecological dimension to Samhain. I’ve never done it, in part because finding such a list is difficult. Compiling a list of the extinct is hard, since we don’t always know a species exists before it stops existing again, and because it’s hard to be sure a whole species is really gone and not holding on in some remnant population somewhere. What lists exist seldom turn up whole on Internet searches, perhaps because many of the species on the list are plants and animals most people have never heard of.
Still, I intend to observe the Day of the Dead by formally noticing our planetary losses.
Looking for Smoking Guns
Which species, if any, have gone extinct because of climate change is a bit complicated. I addressed the question in some depth in an earlier post, but it comes down to the difference between ultimate cause and proximate cause; if you fall off a cliff, the ultimate cause of your death is your poor footing, while the proximate cause is your impact with the ground. The problem is that the connection between those two causes is rarely as obvious or straight-forward as in that example.
Climate change as the ultimate cause of extinction might be linked with any number of proximate causes. Some of them are: drought; habitat loss (think polar bears and sea ice); the extinction or relocation of an ecological partner; and new competitors, pests, or diseases that take advantage of warmer weather. Of course, most of these problems can have other ultimate causes as well. Climate change is not likely to be the species’ only major problem–consider the paper birch, which is dying out in parts of New England because of a combination of exotic diseases, climate change, and probably the advanced age of the relevant stands (the species requires bare soil to sprout, such as after a fire or logging, and there happened to be a lot of that in New England decades ago–hence, a lot of aging birches). Against this complex backdrop, it is hard to say for certain which extinctions actually belong at global warming’s door.
Some years ago, scientists announced the extinction of the Seychelles snail, the first species known to go extinct because of climate change. Fortunately, a previously unknown population of the snail turned up recently–it’s not extinct at all (though presumably still in grave danger). Many writers have treated the snail’s resurrection as some kind of embarrassing “oops” for climate scientists, which of course it is not; the species took a huge hit because of global warming, and the fact that it’s still hanging on is great news. Confirming an extinction is very, very hard–a bit like looking for the absence of a needle in a haystack. Mistakes are inevitable, and welcome.
The golden frog and the Monteverde harlequin frog are sometimes cited as victims of climate change as well. The proximate causes of the golden frog’s demise were habitat loss due to drought and also the chytrid fungus, which could be exacerbated by climate change. Chytrid has extinguished or gravely endangered many other amphibians world-wide, so at least some of them might be considered victims of climate change as well–as could various non-amphibians, including some no one knows about yet.
But there is another way to look at all of this.
Climate change itself has a cause, and that cause has other effects. As I explained in another previous post, our burning fossil fuel has destabilized the biosphere as a whole by altering how energy flows through the system. Climate change is one consequence of that destabilization, but systemic biodiversity loss is another. That is, no matter what the proximate cause of an extinction is (whether climate itself is directly involved), the ultimate cause of this entire mass-extinction event is fossil fuel use.
We know what to do about it. You know what to do about it. If you’re an American citizen, VOTING is a major and necessary step. But this is the festival to honor the dead, and we should take a moment to do that–to remember that these are not just numbers, political statements, arguments, but actual animals and plants, whole ways of being, that will never exist again.
I did find a list of historical extinctions. You can look up the whole thing here. It is far from comprehensive, but even so it’s still too long for me to copy over all of it. I’ll just focus on those from the list that have been lost since my birth.
