   Sea ice and wildfires may be more interconnected than previously   
   thought, according to new research out today in Science Advances.   
      
   By digging into differences between climate models, researchers from   
   the University of Colorado Boulder and the National Center for   
   Atmospheric Research (NCAR) found that soot and other burned biomass   
   from wildfires here in Colorado and elsewhere in the Northern   
   Hemisphere can eventually make their way to the Arctic. Once there, it   
   can affect how much -- or how little -- sea ice persists at any given   
   time.   
      
   This, in turn, can cause ripple effects on climatic patterns for the   
   rest of the globe, reinforcing a feedback loop between the two systems   
   in a way that hasn't been previously seen.   
      
   "This research found that particles emitted from wildfires where people   
   live can really impact what happens in the Arctic thousands of miles   
   away," said Patricia DeRepentigny (PhDAtmos'21), the lead author on the   
   paper and a postdoctoral fellow at NCAR.   
      
   "Sometimes the Arctic can be seen as this region that we shouldn't care   
   about because it's so far away from where we live … but the fact that   
   there's this back-and-forth of what happens here with the wildfires can   
   affect the sea ice, and a diminishing sea ice can then lead to more   
   wildfires here, connects us with the Arctic a little bit more."...
