Historical Climate Changes
qClimate changes over the last 1000 years have been smaller
than those over tectonic, orbital, and
glacial-age millennial time scales, never
exceeding 1°C on a global basis.
qClimate changes over the last several thousand years
have been highly variable in pattern from
region to region.
