Under a “higher emissions pathway” – in which the world continues to burn fossil fuels and levels of planet-warming pollution continue to rise – the study projects the Arctic will see a complete loss of sea ice from August until as late as October before the 2080s, Min said.Ī section of the Central Arizona Project, a series of aqueducts and tunnels designed to bring water from the Colorado River to central and southern Arizona, in Phoenix, Arizona, US, on Tuesday, May 9, 2023. The warmer it gets, the more likely the Arctic is to stay free of sea ice further into the colder season. Once Arctic summers become ice-free, the buildup of sea ice in the colder seasons will be much slower, Min said. “We were surprised to find that an ice-free Arctic will be there in summer irrespective of our effort at reducing emissions, which was not expected,” Seung-Ki Min, lead author of the study and professor at Pohang University of Science and Technology in South Korea, told CNN.Īrctic ice builds up during the winter and then melts in the summer, typically reaching its lowest levels in September, before the cycle begins again. They found that declining sea ice was largely the result of human-caused, planet-heating pollution, and previous models had underestimated Arctic sea ice melting trends. Global loss of wildlife is 'significantly more alarming' than previously thought, according to a new study The idea is to collect data that allows understanding "the dynamics" of this neotropical forest.Ĭhucanti, a reserve in the Darien of Panama with an overwhelming biodiversity - Bienvenido Velasco/EPA-EFE/Shutterstock In the reserve area there are more than 40 camera traps, twenty in the canopy - the layer of branches and leaves formed by the tops of neighboring trees - and the others in the understory - the variety of vegetation that grows in the areas closest to the floor.
