| Summary: | Some of the impacts from changes in ice and snow are immediately visible, often showing up as increased frequencies of events that are within the range of natural variation. For example, winter roads might be open on average fewer days in the Arctic; feeding conditions might be poor for caribou and reindeer more frequently than in the past; amount and timing of runoff from snowmelt in the Andes, Alps or Himalayas might result in local water shortages in more years. Over time these short-term events lead to longer-term consequences including changes in biodiversity, ecosystems and regional economies.
