There's something in the air - 1.5 million years ago

Interesting piece on BBC Breakfast today about scientists drilling way down into the Antarctic ice to collect samples that were formed up to 1.5 million years ago.

Once shipped back to Cambridge, they are processed to release tiny trapped air bubbles that provide a snapshot of the composition of the atmosphere over the years.

Fascinating stuff.

Fascinating stuff maybe, but what are the benefits today?

Are minute samples really going to tell us something important?

Durrrhh yeah...it will prove that flat earth is true...it will also release some clean air.

From Wiki ICE CORE

"The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, and the air trapped in tiny bubbles can be analysed to determine the level of atmospheric gases such as carbon dioxide. Since heat flow in a large ice sheet is very slow, the borehole temperature is another indicator of temperature in the past. These data can be combined to find the climate model that best fits all the available data."

Whether or not you consider that 'something important' is for you to decide.

Apart from Antarctica being a 'frozen waste' - without the current human 'habitation' (albeit transient), I have concepts of ancient times being filled with fire and brimstone, so maybe a taste of sulphur?

Not unless you're interested in climate science, which is a pretty obscure and pointless area of study these days, right?

Yup they release the global disease which was a pandemic and killed off the human population then.

Well, dinosaurs lived to a ripe old age in Antarctica, you know...

Something definitely in the air down there as I've been told the scientists in Antarctica now brew their own alcohol.
I've been reliably informed that this particular Antarctic base is a distillery with a research problem.

Will the air have strontium 90 in it?

As far as we know, there wasn't any until we, that is humans, started letting off big bombs. Now it is in every living being on the planet.

But what if the air in these bubbles contained this isotope, or at least, yttrium-90? Would it mean the comment above about a prior human, or human-like species might be true?
