Nah. For centuries up to the 1850s, climate was looking pretty dicy. The little ice age, had it gone on, might have represented a return a big ice age.

The heroic efforts of early industrialists adding carbon to the atmosphere avoided this calamity and set us up with a level of comfy and productive climate unknown in the quaternary.

Amazing how humanity keeps lucking out like this.

Climate is out. Climate tech too.

AI is in.

Conservationists and archivists (sometimes) use gloves on cleaned samples, but not archaeologists. An archaeologist wearing gloves is almost certainly just cold.

There's no real reason to immediately protect the find from light handling when it's discovered. It's a dirty object that's still coated in whatever was floating around the environment for those thousands of years. The rock will be fine and probably handled multiple times before it gets back to an archive.

I think the only times I've worn gloves in the field were for a very rusty metal dagger and some especially sensitive human remains.

Thats one pretty arrowhead

Me too but presumably they’re not really that unique as there are hundreds? Or maybe the stone/hard artifacts are handled different than organic/soft.

That's because they weren't exposed to the weather as much. Essentially these were 'shrinkwrapped' in nature's own version of Cosmoline. No bacteria, no free oxygen. Once did this with a rose to see how long it would last and it basically was perfect until we moved house. Many years and not even the slightest change, it didn't even lose color.

Yes: most mainland Norway ice was gone during the holocene climatic optimum (9–6 thousand years ago), and glaciers recovered since then (until approx the 20th century, when deglaciation started accelerating again).

The climate is varying in long cycles, and the deglaciation 20 thousand years ago (last glacial maximum) was driven by a spike in summer temperatures, and this peak has already long passed. Ice ages and interglacial periods have a certain momentum to them, so it takes more than just that to go back to full ice age..

Yes, the early Neolithic was warmer than modern era.

Whatever you put in the glacier the glacier gives back to you. Anything you leave there ends up at the bottom of it in the moraine.

Yes.

I come from a land down under

That last sentence is how we know you've never been there. The ratio is the same as anywhere else.
