Dear MEL School’s Topic Readers,
Mystery AD1257
eruption traced to Lombok, Indonesia.
Just like a
criminal investigation, a scientist says. Without suspecting or assuming who or
what caused an incident, those investigators or scientists collect as much data
and evidence as they can, and deduce a possible suspect or cause of the
incident, if they can.
In geochemistry,
it is the ice cores that made them track which volcano was responsible for the sudden
cooling of the climate in global-scale, which caused huge drop in harvest and
starvation in the following year. In this case, sulfur and dust from this
Indonesian volcano that was found in ice in Arctic and Antarctica provided such
traces.
Enjoy reading and
learning how scientists figure out the cause of climate change in the past.
