This makes it sound like the designation is latent, even if rejected by committee right now. They acknowledge an anthropogenic "event" is under way but aren't admitting the anthropocene because of its recency and unclear boundaries. But the boundaries of other epochs are also only estimated and didn't unfold completely overnight, not even for the K-Pg impactor, probably the most sudden change in the geological record…

> They acknowledge an anthropogenic "event" is under way but aren't admitting the anthropocene because of its recency and unclear boundaries.

You mean aren't admitting the anthropocene as an epoch? That's not what the article says. The reason it's not admissible as an epoch is because we might blow ourselves up tomorrow and wipe out industrial civilisation. And the whole layer of steel and concrete we laid down would be very thin in the record, like the K-Pg impact. The banded iron formations are kind of on the boundary, they're associated with the Great Oxygenation Event but you could also maybe call it the Jatulian period. That was a couple hundred million years.

Those are classified as events, not epochs. The K-Pg impact was an event.

Ed. I guess you could also say why can't we have a new Anthropocene period caused by an Anthropocene event, but I don't know what to tell you, it's just confusing to do that. That's why the K-Pg impact is followed by the Danian age, not the The-Start-Of-This-Period-Has-A-Lot-Of-Iridium age. I don't get why the proposal didn't want to call it the Crawfordian if that's where the canonical marker is found

Huh. That looks like really important context. I wonder why the Smithsonian article neglected to mention it. Do they just not want to admit that there's any dissent?

It does seem pointless to avoid naming a new era for dramatic irreversible changes that would have defined a new era if they happened millions of years ago. How many common assumptions about the Holocene are already broken? -- With much less at stake, I think it was out of touch and impractical to choose scientific terminology at odds with existing common language, when "dwarf planet" was defined as not a subcategory…

"Planet" derives from the Greek word for "wanderer", so it's totally on brand if the category keeps moving around.

Yes. The entire Pluto thing seemed like a pedantic waste of time. Or, at least grandfather it in. Now everyone still thinks of it as a planet, but we have to qualify it when talking : "Oh hey I read an interesting story about the 9th planet Pluto, ooops, sorry, I mean 'dwarf', don't crucify me".

I think the proposing team ran out of options on the formal track so now they're going the ad-hominem track against the IUGS (they're uncomfortable with the Anthropocene, they're climate-change deniers, etc.)

This seems like a reverse logic article. Here are 'myths', but really 'Not'.

It isn't against naming this the Anthropocene, all of the myths are followed by reasons why they aren't myths and this is probably the Anthropocene. "From a certain point of view".

Earlier quoted context omitted.

We already had 'minor planets' (asteroids). Planets are a continuum, from small rocky or icy ones the size of large moons, to "terrestrial" ones, to ice giants and gas giants.

Yes, that is how I think "planets" should be used. A root category over any number of subcategories defined over continuums and combinations of other features. As it is used in common langauge.

Honestly, it is hubris to start the anthropocene in just the last human lifetime. Our species has been making an impact that will be evident in the geological record for longer than that.

e.g. Geologists of some far-off future are going to notice that species that were isolated to one continent suddenly started popping up everywhere in the fossil record a few hundred years ago. Sea travel has united the continents in way they haven't been united since Pangea.

A few hundred years will be indistinguishable from a single human lifetime to those future geologists. To us however, it's an important distinction.

From an exceedingly anthropocentric point of view.

People assume that humans are the only or first animal of the Holocene to have left lasting global impacts. The mastodons essentially great swaths of steppe. Ants and worms have essentially altered the grounds. Bacteria generate the bulk of the oxygen. Beavers change the course of rivers and create lakes. The number of critters that alter the Earth is quite numerous. Humans also alter the Earth, and in increasingly large ways, but naming an epoch after humanity seems… egotistical when other critters do stuff equally impressive when scale is factored in.
