“Arctic Sea Ice \u2013 the big picture and the small cracks”<\/h2>\n

Arctic sea ice is shrinking fast, reshaping the Arctic Ocean and its role in the global climate system. As the ice retreats and changes character, its influence on ecosystems and societies is shifting in ways we are only beginning to grasp. In this event, three researchers will show how climate prediction and sea\u2011ice modelling shed light on what the Arctic of tomorrow may look like.<\/em><\/p>\n

The event is held in English<\/strong><\/p>\n

Arctic sea ice is declining, and the Arctic Ocean is shifting from white to blue. But what does that really mean\u2014for us, for the planet, and for the ice itself? Why do scientists devote so much effort to understanding sea ice, even as headlines claim the Arctic will soon be \u201cice\u2011free\u201d?<\/p>\n

In reality, sea ice will not vanish completely from the Arctic as long as Earth\u2019s tilt continues to bring months of winter darkness and cold. But that does not mean we can relax. Sea ice acts like a reflective blanket: it sends much of the Sun\u2019s energy back to space, cooling the planet, and it insulates the ocean from the atmosphere. As it retreats, the consequences for the global climate, Arctic ecosystems\u2014and eventually for human societies\u2014will be lasting and significant.<\/p>\n

And it\u2019s not only about how much ice we lose. The character of the remaining ice is changing too, in ways we don\u2019t yet fully understand. Will the future Arctic feature more cracks and openings? Fewer large ice plates and more small, fragile floes? Less total ice, yet more seasonal growth?<\/p>\n

To anticipate the future of the Arctic Ocean\u2014and of our climate\u2014we need to understand the sea ice of tomorrow.<\/p>\n

In this event, three researchers, all connected to the\u00a0Bjerknes Centre<\/a>, will share how their work in climate prediction and sea\u2011ice modelling helps reveal the changing role of sea ice in today\u2019s world and in the decades ahead.<\/p>\n<\/div>\n
