Weather and climate are driving forces for northern ecosystems. Weather influences our environment every season, every year. One extreme weather event can affect wildlife or habitats for many years. Climate is the average of weather over a long time.
Weather and climate are directly related to changes in northern ecosystems, including chagneds in wildlife habitat, changes in spacies composition and changes in forest fire patterns.
Indicators on observed weather and climate trends can be compared with trends predicted by climate change models to help us adjust these predictions to the future.
