Observed ecological changes associated with a change in climate include the advance of spring events, species distribution changes, community shifts and asynchrony in species interactions.
U.S. forests play a large role in offsetting carbon emissions, about 20 % of the U.S. fossil fuel carbon output. If a forest replaces itself after a disturbance like fire, then there is no long-term loss of carbon.
Tropical forests are critical ecosystems affecting the Earth's climate and hydrological cycles, and human cultures. Learn more about how they may be affected by climate change.
The effect of disturbances, such as increased fires and insect attacks, will drive ecosystem change as much or more than warmer temperatures from climate change.
