This is documented by many modelling studies, but only [...] sea ice have a significant effect on the energy exchange between the atmosphere and the ice covered ocean. Uncertainties in the representation of sea ice albedo contribute considerably to the differences

However, jellyfish in the world’s oceans could actually benefit from the rising water temperatures – also and especially in the Arctic Ocean, as researchers from the Alfred Wegener Institute [...] Institute have now successfully shown. In computer models, they exposed eight widespread Arctic jellyfish species to rising temperatures, sea ice retreat and other changing environmental conditions. The result: [...] triple the size of its habitat – with potentially dramatic consequences for the marine food web and Arctic fish populations. The study was just released in the journal Limnology and Oceanography.
