Carbon emissions aren’t just changing the climate — they’re making it harder to solve crimes. As our atmosphere fills with fossil carbon, scientists will have a tougher time using radiocarbon dating, a standard forensic technique, to analyze human remains and wildlife tissues.
We used to think that the human brain was unchanging once a person reached maturity. Not true. One of the things that helped debunk this idea was the most destructive weapon ever created. This is what nuclear bombs proved about the human brain.
Most radioactive isotopes of the lighter elements decay in minutes or less. But one particular isotope of carbon takes 6000 years to decay, and that fact has revolutionized archaeology. But why it does that has long been a complete mystery.
