After years of research on the Greenland ice sheet — which CNN visited when the cores were drilled — scientists have reported temperatures there have been the warmest in at least the past 1,000 years.
As humans fiddle with the planet’s thermostat, scientists are piecing together Greenland’s history by drilling ice cores to analyze how the climate crisis has impacted the island country over the years. The further down they drilled, the further they went back in time, allowing them to separate which temperature fluctuations were natural and which were human-caused.
” During pre-industrial times, there were no weather stations in Greenland that gathered temperature data like today. That’s why the scientists relied on paleoclimate data, such as ice cores, to study the region’s warming patterns. The last robust ice core analysis in Greenland ended in 1995, and that data didn’t detect warming despite climate change already being apparent elsewhere, Hörhold said. “With this extension to 2011, we can show that, ‘Well, there is actually warming,’” she added.
