There has always been climate change, for millions of years. The earth is constantly changing, very slowly, most of the time. From Smithsonian:
Their findings add to the growing body of research about how changes in the climate—like those occurring today because of human-caused global warming—can also affect human health.Share
“Investigating the resilience of ancient societies to past climate change … might give us better insight into these relationships and the climate change-induced challenges we are facing today,” lead author Karin Zonneveld, a micropaleontologist at Germany’s University of Bremen, tells Live Science’s Stephanie Pappas. To study the climate of the Roman Empire, scientists drilled down into the sediment of the Gulf of Taranto, a body of water between the “sole” and “heel” of Italy’s boot. They pulled out long samples of the sediment, then analyzed the various layers, similar to how dendrochronologists study tree rings.
They were able to link layers of sediment with specific periods in time because of the presence of volcanic glass from well-known volcanic eruptions throughout history, including the infamous eruption of Vesuvius in 79 C.E. (Read more.)
