Babylonian Captivity and Carbon Dating

I just saw news archaeologists have found the burning of Jerusalem by Nebuchadnezzar's general, as mentioned in Jeremiah, and dated the burning to 2600 years ago.

2600 years ago is 583 BC, very close to the 586 BC for siege of Jerusalem at first exile.

This means that 2600 years ago, carbon content was c. 100 pmc in the atmosphere./HGL
