Even though it only lasts in the atmosphere for days or weeks, it can travel far and wide on winds. And in the Arctic, it can have a disproportionate impact on warming, Prior says.<\/p>\n<p>\u201cThe problem with black carbon is that, not only is it a climate heater, it actually has a double whammy effect when it settles out onto snow and ice,\u201d she explains. That\u2019s because polar ice and snow \u2014 which in the past reflected large amounts of solar energy back into space \u2014 is now darkened by the black carbon, so it absorbs more sunlight, accelerating melting.<\/p>\n<p>This increased melting also reduces Earth\u2019s albedo effect over time, as the widening loss of sea ice and snow exposes larger areas of darker-colored land and water, which absorb even more heat, reducing the reflective capacity of the polar ice cap, which in turn results in more melting.<\/p>\n<p>\u201cYou end up with this never-ending cycle of warming,\u201d Prior explains.<\/p>\n<p>Accelerating <a href=\"https:\/\/news.mongabay.com\/2024\/09\/arctic-sea-ice-hits-summer-minimum-antarctic-hovers-at-new-winter-lows\/\" data-wpel-link=\"internal\">loss of Arctic sea ice<\/a> is a major concern, scientists say, with some estimates forecasting <a href=\"https:\/\/climate.esa.int\/en\/projects\/sea-ice\/news-and-events\/news\/simulations-suggest-ice-free-arctic-summers-2050\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external\">ice-free Arctic summers as early as the 2050s<\/a>.
