Animations over time of
historical and future climate, biomass accumulation,
and vegetation indices.
For more information on future
climate emission scenarios, follow this link to information and descriptions
of the scenarios from the World Meteorological
animations run through 130 years of historical climate
(temperature or precipitation) and 100 years of climate
predicted by a high CO2
emission scenario (A2).
Anomaly animations show the departure from the
average climate over the period 1970-1999. So, a positive
anomaly value indicates that the observed climate was
warmer/wetter than the average climate from 1970-1999, while
a negative anomaly indicates that the observed temperature
was cooler/drier than the average climate from 1970-1999.
animation runs through 200 years of potential biomass
accumulation, predicted across the globe by a simple model
using either historical or future temperature and
precipitation. It also graphically displays the biomass
accumulation for 5 North American biomes.
