That traditional lifestyle that the Inupiat have maintained for thousands of years is vulnerable to the effects of climate change. In Alaska, the average temperature2.5 degrees (1.4 degrees Celsius) since 1992, according to the U.S. National Oceanic and Atmospheric Administration. The Arctic had been warming twice as fast as the globe as a whole, but now has

in some seasons, according to the Arctic Monitoring and Assessment Program.EDITOR’S NOTE: This story is part of an ongoing series exploring the lives of people around the world who have been forced to move because of rising seas, drought, searing temperatures and other things caused or exacerbated by climate change.Children play in Shishmaref, Alaska, Friday, Sept. 30, 2022.

Shishmaref sits on the small island of Sarichef -- just a quarter of a mile wide and about three miles long. Only about half of it is habitable, but hundreds of feet of shore have been lost in past decades. A warmer climate also melts faster a protective layer of ice during the fall, making it more susceptible to storms. In October 1997, about 30 feet of the north shore was eroded after a storm, prompting the relocation of 14 homes to another part of the island, according to a report by the Alaska Department of Commerce. Five more homes were moved in 2002.One way to show humans caused the warming “is by eliminating everything else,” said Princeton University climate scientist Gabe Vecchi.

Scientists can calculate how much heat different suspects trap, using a complex understanding of chemistry and physics and feeding that into computer simulations that have been generally accurate in portraying climate, past and future. They measure what they call radiative forcing in watts per meter squared.The first and most frequent natural suspect is the sun. The sun is what warms Earth in general providing about 1,361 watts per meter squared of heat, year in year out. That’s the baseline, the delicate balance that makes Earth livable. Changes in energy coming from the sun have been minimal, about one-tenth of a watt per meter squared, scientists calculate.

But carbon dioxide from the burning of fossil fuels is now trapping heat to the level of 2.07 watts per meter squared, more than 20 times that of the changes in the sun, according to the U.S.Methane, another powerful heat-trapping gas, is at 0.5 watts per meter square.
