class=\"wp-block-paragraph\">\u82f1\u6587\u539f\u6587<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Arctic ice sheet is one of the largest frozen systems<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">on the surface of our planet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For tens of thousands of years,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">thick layers of sea ice and continental glaciers<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">have wrapped the northern polar region,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">shaping the global climate pattern<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and supporting a unique polar biological community.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In recent decades, rising global temperatures<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">have triggered continuous and accelerating melting<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">across the entire Arctic zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The shrinking Arctic ice is not merely a local polar change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It sets off a chain reaction<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">that ripples through ocean circulation,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">weather systems and the survival of countless species.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sea ice in the Arctic Ocean undergoes<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">seasonal freezing and melting every year.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Winter brings extensive ice expansion,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">while summer warmth causes the ice edge to retreat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But satellite observation records over the past forty years<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">reveal a clear long-term trend.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The summer sea ice coverage keeps shrinking year by year,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and the average thickness of sea ice drops sharply.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Old multi-year ice, thick and stable,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">is disappearing at the fastest speed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Young thin ice forms in winter<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and melts completely once summer arrives,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">which cannot maintain a stable polar ice environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Albedo effect is the core driving factor<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">that speeds up Arctic melting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bright white ice and snow reflect most solar radiation<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">back into outer space.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When ice melts and exposes dark seawater,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">the ocean surface absorbs far more heat from sunlight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Warmer water then melts more surrounding ice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This positive feedback loop continues to amplify warming,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">making the Arctic warm much faster<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">than most other regions of the earth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The melting ice reshapes the whole Arctic food web.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Polar bears rely on solid sea ice<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">to travel, hunt seals and raise their cubs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With shortened ice periods,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">they have less time to hunt and store fat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many individuals face starvation,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and the breeding success rate gradually declines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seals build their birth dens on stable ice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Early ice collapse crushes dens<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and leaves newborn pups exposed to predators and cold wind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even tiny algae growing on the bottom of sea ice<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">are affected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These micro-organisms form the base of the polar food chain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Their reduction will influence krill, fish, seabirds<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and every creature higher up the chain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Melting glaciers and sea ice pour massive fresh water<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">into the Arctic Ocean.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh water is lighter than saltwater,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">so it floats on the sea surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may slow down the global thermohaline circulation,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">the large-scale current system<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">that transports heat between equatorial and polar seas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Changes in this ocean current<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">can bring unexpected shifts to rainfall,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">temperature and extreme weather<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">in Europe, North America and East Asia.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Arctic also stores huge amounts of organic carbon,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">trapped in permanently frozen permafrost.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the ground thaws, microbes break down buried plant matter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They release methane and carbon dioxide,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">two potent greenhouse gases,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">further pushing global temperatures upward.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Human activities in the Arctic are also changing quickly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Receding ice opens new shipping routes,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and exposes mineral and fossil fuel resources<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">that were once inaccessible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More vessel traffic, resource exploration and settlement plans<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">bring pollution risk and wildlife disturbance<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">to this once remote and quiet wilderness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Though the Arctic faces severe pressure,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">scientists still believe protective actions<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">can slow the pace of destruction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cutting greenhouse gas emissions,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">strengthening Arctic environmental monitoring,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and setting rules for polar commercial activities<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">can ease the rate of ice loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The melting Arctic ice sends a clear warning signal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The polar frozen world acts as the earth\u2019s thermal regulator.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its gradual disappearance shows<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">that global climate balance is being disturbed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What happens in the Arctic does not stay in the Arctic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The transformation of this distant icy landscape<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">will eventually touch ecosystems and human societies<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">across every continent.<\/p>\n\n\n\n<p
