Blue ice is seen at frozen Kongsfjord near Ny-Aalesund, Svalbard, Norway, April 8, 2023. Researchers have been studying the polar region for decades, with Ny-Aalesund'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.

CNR (Italian National Research Council) station leader Ombretta Dell’Aqua, 43, stands lookout for polar birds while Paul Scherrer Institute Switzerland chemist Francois Burgay, 34, prepares to take a snow sample to detect molecules connected to Phytoplankton bloom, next to Gruvebadet aerosol sampling station in Ny-Aalesund, Svalbard, Norway, April 5, 2023. Filling plastic test tubes with snow, Burgay looks for chemical signals from marine algae blooms that travel from the ocean to the atmosphere and are later deposited in the snow, and once these signals are identified, there is hope that scientists will be able to use them to understand how the Arctic waters changed in the past and project how they might change in the future. "One of the special things about this place is there are a lot of different scientists. I'm a chemist. There are biologists, geologists," he said. "It's one of the few places in the world where these kinds of exchanges are so informal and so spontaneous." REUTERS/Lisi Niesner SEARCH "NIESNER ICE" FOR THIS STORY.
