The driving force of evolution is natural selection.
Natural selection promotes survival of the fittest organisms, with best adapted traits.
Climate change can cause changes in specific environmental factors, e.g. rainfall, sea ice surface.
Environmental changes can change selection pressures, so that different traits become the best adapted traits.
By changing environmental factors climate change is a factor in evolutionary change.
E.g. Darker colour variants of the Tawny owl will be an advantage in the absence of snow.
Climate change may result in extinction of species/cause loss of diversity.
