(Phys.org) -A combined team of researchers from the U.S. and China has projected, using a climate simulation tool, that the Arctic will become September ice-free sometime during the years 2054 to 2058.
Ice-free in this context refers to a time period during any given year—generally arriving in September after withstanding the heat of summer. Not long after scientists
began to recognize that the planet has been heating up, many began to realize that a warmer planet would mean warmer temperatures in the Arctic—enough warming and the Arctic would eventually become ice-free during part of the year. Many researchers using many models and simulations have sought to project when that might happen, as global warming
projections have now made it a near certainty. In this new effort, the research team used a climate modal called Coupled Model Intercomparison Project Phase 5 (CMIP5). Phase 5 is the latest version of the model, which is why the team chose to use it.
