Radiocarbon dating volcanoes 16 dating a 23 year old
Meanwhile, others say the beginning was more like the 16th century.The scientists with the volcano theory – at University of Colorado Boulder with co-authors at the National Center for Atmospheric Research (NCAR) and other organizations – have evidence for volcanic eruptions between 12 AD.
This figure summarizes sunspot number observations. During the long Maunder Minimum, almost no sunspots were observed.The Little Ice Age is the name for a period of widespread cooling on Earth.Scientists don’t agree on when it started and ended, but it’s generally agreed to have lasted into the 19th century. Still, it’s known that northern Europe felt cooling temperatures.Places as far away as South America and China might also have cooled.Scientists don’t know exactly what caused the Little Ice Age – but there are theories. It’s the idea that an unusual, 50-year-long episode of four massive tropical volcanic eruptions triggered the Little Ice Age between 12 A. Those dates might correspond with the beginning of the Little Ice Age, which might have begun as early as the 13th century.

They say these volcanoes triggered a chain reaction, affecting sea ice and ocean currents in a way that lowered temperatures for centuries.
