  2. Arctic sea ice

    Arctic Ocean likely to become ice-free in the summer for first time before 2050

    The Arctic Ocean is likely to have its first ice-free summer before 2050, according to an analysis of simulations from more than 40 different climate models. How frequently the sea ice vanishes in the summer depends on the rate of greenhouse gas emissions in the future.

  4. The Polarstern frozen in Arctic sea ice.

    Arctic research expedition likely faces extreme conditions in fast-changing Arctic

    Scientists at the National Center for Atmospheric Research (NCAR) have used an ensemble of multiple climate model runs to simulate conditions along potential routes for the MOSAiC polar expedition, using today’s conditions in the “new Arctic.” The results suggest that thinner sea ice may carry the ship farther than would be expected compared to historical conditions and the sea ice around the ship may melt earlier than the 12-month goal. Of the 30 model runs analyzed in the new study, five (17%) showed melt-out in less than a year.

    A ‘bucket full of photons’ may yield clues about the Sun's magnetic fields

    Scientists at NCAR designed and built one of the Inouye Solar Telescope’s five instruments: the Visible Spectro-Polarimeter (ViSP). This extremely versatile instrument can observe any wavelength across the visible spectrum of the Sun’s radiation, allowing scientists a huge degree of flexibility to explore.
