qNatural systems are
vulnerable to climate change, and some
will be irreversibly damaged.
qNatural systems at risk include glaciers, coral reefs and atolls, mangroves, boreal and tropical
forests, polar and alpine ecosystems,
prairie wetlands, and remnant native grasslands.
qIt is well-established that the
geographical extent of the damage or loss, and the number of systems affected, will increase with the
magnitude and rate of climate change.
