Reply to How is radioactive dating used to determine historical greenhouse gas levels and temperatures? by pog_irl
The dating doesn't give you the gas levels or temperatures.
Instead separate samples are taken through an ice core, or a sediment core, or a rock sequence. Separate analyses are done on the samples to measure the greenhouse gas levels, temperatures, and ages.
Sediment samples might have carbon isotopes measured as a proxy for CO2, ice cores might have gas bubbles analysed, there's a whole suite of different measurements possible. The dating is totally separate and just puts some age pins on those measurements.

Why? Was she the one who measured them?

It's just not the right way to compare nuclear with solar and wind. And you can't put wind or sunlight in a fuel tank.

Not left off so much as can't be shown. What's the energy density of wind?

Reply to comment by rdrckcrous in TIL researchers found that the global average temperature from 19,000 to 23,000 years ago was about 46 degrees Fahrenheit. That’s about 11 degrees Fahrenheit (6 degrees Celsius) colder than the global average temperature of the 20th century, per a University of Michigan statement. by Embarrassed-Mouse-49
Global average was that much cooler. Not everywhere cools by the same amount. The further away from the equator, approximately, the more intense the cooling.
Same thing in reverse now. Global average up 1°C since 1880, but parts of the Arctic are over 4°C warmer.

Reply to comment by Landlubber77 in TIL that a branch of the Clan Bruce in Scotland, relatives of Robert the Bruce, emigrated from Scotland to Russia to 1647. Many families of Scottish origin were also part of the Russian Empire's landed aristocracy, including descendants of Clan Ramsay, Clan Leslie, Clan Drummond, and Clan Hamilton. by Obversa
Wasn't Beyoncé one of their descendants?

The head of state is literally the head of the church, and the government appoints religious leaders. Smh. Definitely a Christian nation.

No, but my friend does, and has done some bits with me. Felt to me a bit like a Rorschach test - there's not really anything there, but you see what you see, and can learn something about yourself as a result.

Basically there are tests they can do to determine if that has happened, and where it has that data is dumped.
