How does carbon dating work

A geologist, accustomed to putting his lab’s high-tech nanoscale scanning electron microscope (nano SEM) to work evaluating the mineral composition of rocks and meteorites, has now been enlisted for ...Humans must reduce net greenhouse gases emissions to zero “well before 2040” in order to ensure global warming does not go above 1.5 degrees Celsius by the end of the century, scientists have warned after carrying out a study using a sophisticated new computer model.Under the Paris Agreement on climate change, the world committed to prevent global warming from going above 2C but also attempt to restrict it to as close as 1.5C as possible amid mounting evidence that dangerous effects could kick in sooner than previously thought.

One popular theory about the Paleolithic cave paintings proposes that sites were chosen based on the acoustics in the caves.

The originators of the theory reported a causal connection between the ...

In conventional dating methods, scientists remove a small sample from an object, such as a cloth or bone fragment.

Then they treat the sample with a strong acid and a strong base and finally burn the sample in a small glass chamber to produce carbon dioxide gas to analyze its C-14 content.

One of the researchers, Dr Michael Obersteiner, of the International Institute for Applied Systems Analysis near Vienna, said: “The Feli X model ...
