However, a little more knowledge about the exact ins and outs of carbon dating reveals that perhaps it is not quite as fool-proof a process as we may have been led to believe.

At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it.

Half-life refers to the amount of time it takes for an object to lose exactly half of the amount of carbon (or other element) stored in it.

This half-life is very constant and will continue at the same rate forever.

Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so - a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.

Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30,000 years ago, or nearly half as long as was hitherto thought.

Specifically, each nucleus will lose an electron, a process which is referred to as decay.

This rate of decay, thankfully, is constant, and can be easily measured in terms of ‘half-life’.

As scientists who study earth’s (relatively) modern history rely on this measurement tool to place their findings in the correct time period, the discovery that it is unreliable could put some in a quandary.
