CNR (Italian National Research Council) geochemist and expedition leader Andrea Spolaor, 39, walks along the Ice Memory drilling camp, near Ny-Aalesund, Svalbard, Norway, April 10, 2023. A team of scientists was drilling 125 meters into Dovrebreen glacier, hoping to collect two ice cores for studying 300 years of climate records – part of an effort by the non-profit Ice Memory Foundation to collect and preserve ice cores from melting glaciers around the world – and were shocked when the drill, at only 25 meters deep, suddenly sloshed into a massive pool of water. "We did not expect such a huge water flux coming out from the glacier, and this is a clear sign of what is happening in this region," Spolaor said. "The glacier is suffering."

NPI (Norwegian Polar Institute) scientists ride their snowmobiles as the sun sets at the banks of Kongsfjord and the Kronebreen glacier near Ny-Aalesund, Svalbard, Norway, April 10, 2023. Researchers have been studying the polar region for decades, with Ny-Alesund's weather records going back more than 40 years, but as Svalbard temperatures climb up to seven times faster than the global average, scientists' work has become vitally important because what happens in the Arctic can impact global sea levels, storms in North America and Europe, and other factors far beyond the frozen region.
