Most Abrupt Ever carbon14 increase in the earth’s atmosphere
An international team led by researchers at Nagoya University, along with US and Swiss colleagues, has identified a new type of solar event and dated it to the year 5480 BC; they did this by measuring carbon-14 levels in tree rings, which reflect the effects of cosmic radiation on the atmosphere at the time. They have also proposed causes of this event, extending our knowledge of how the sun behaves.
When the activity of the sun changes, it has direct effects on the earth. For example, when the sun is relatively inactive, the amount of a type of carbon called carbon-14 increases in the earth’s atmosphere. Because carbon in the air is absorbed by trees, carbon-14 levels in tree rings actually reflect solar activity and unusual solar events in the past. The team took advantage of such a phenomenon by analyzing a specimen from a bristlecone pine tree, a species that can live for thousands of years, to look back deep into the history of the sun.
Another interpretation of this event: a sudden change in atmospheric conditions like the dissolving of the water canopy around our planet at the time of the global flood at Noah’s time, as described in Genesis 7:11 “In the 600th year of Noah’s life, in the second month, on the 17th day of the month, on that day all the springs of the vast watery deep burst open and the floodgates of the heavens were opened.”
