[Climate Progress] Those concerned with climate change spend a lot of time arguing that it’s not just an environmental problem, but also an economic, human rights, national security, and even mental health issue. Now a new study has found that greenhouse gas emissions could impact a range of unlikely fields due to their effect on radiocarbon dating, a much-heralded scientific method used to determine the age of objects containing organic material.
The study, published Monday in the Proceedings of the National Academy of Sciences, found that emissions from fossil fuels are artificially raising the carbon age of the atmosphere, which makes objects today seem much older than they are when scrutinized by a radiocarbon dater. This change in the ability to date objects could impact measurements commonly taken in a broad range of endeavors, including archaeology, forgery detection, forensics, earth science, and physiology.
For instance, the study suggests that by 2050 — just 35 years from now — new clothes could have the same radiocarbon date as something worn during the Battle of Hastings in 1066. [MORE HERE]

The Stickiness of the Fossil Fuel Age
Interesting piece on the distortion of carbon dating caused by the fossil fuel age here. It seems like Tim Morton's analysis of global warming as a hyperobject, perhaps most notably its trait of viscosity, could be applied to this in an illuminating manner.
