Pollution emerges as the missing piece in an Arctic ice puzzle, highlighting humanity's vast impacts, although there is a glimpse of hope for the future.
Air pollution from fossil fuels is altering the fundamental atmospheric chemistry of the remote Arctic, according to a new study in the journal Nature Geoscience. The findings highlight the global reach of industrial pollution and underscore the importance of clean air regulations.A team headed by Jacob Chalif and Professor Erich Osterberg of Dartmouth College, analyzed ice cores from Alaska and Greenland.
'By releasing all this pollution into the world, we're fundamentally altering atmospheric processes,' Chalif said. 'The fact that these remote areas of the Arctic see these undeniable human imprints shows that there's literally no corner of this planet we haven't touched.'Despite the concerning findings, the study also offers a glimmer of hope.

Arctic sea ice near historic low; Antarctic ice continues declineArctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline continues the decades-long trend of shrinking and thinning ice cover in the Arctic Ocean.

Lake ice quality degrading as planet warms—skaters, hockey players, ice truckers on thin iceIce may look safe for a game of pick-up hockey on the lake, but as a new study out of York University found, looks can be deceiving. Warming winters are not only affecting ice thickness and timing—when a lake freezes and thaws—but also quality, making it potentially unstable and unsafe.

Arctic warming may fuel ice formation in cloudsRising temperatures are thought to reduce the number of ice crystals in clouds, leading to the formation of liquid-dominated clouds. However, a new study has found that Arctic warming is causing an increase in the emission of natural aerosols from snow/ice-free barren and vegetated areas in the Arctic.
