Ecosystem Impacts and Adaptations
Climate change will impact terrestrial ecosystems in many different ways around the world. Changes in temperature, precipitation and atmospheric greenhouse gases alter the conditions for vegetation growth and ecosystem structures.
For example, plant growth rates may increase due to longer growing season lengths and higher atmospheric CO2concentrations. On the other hand nutrient limitation and more intense droughts and heat waves may cause lower productivities in certain vegetation ecosystems.
Climate change may increase the frequency and intensity of natural disturbances such as fire or the occurrence of insects, which is already being observed in many parts of North America, in particular in Canada’s northwest region. Climate impacts will be more pronounced in northern latitudes and most vegetation ecosystems in these regions will be forced to adapt.
Short term and long term changes in temperature, precipitation and atmospheric CO2, alter the conditions for vegetation growth and ecosystem structures.
