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 Organization.

Climate Animations*

These 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.

Biomass Accumulation Animation*

This 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.

NDVI animation

This animation shows global monthly NDVI (Normalized Difference Vegetation Index, a measure of the 'greenness' of an area) measured by the MODIS (MODerate-resolution Imaging Spectroradiometer) satellite for 2000 to 2011.  Average NDVI for the northern and southern hemispheres is displayed on the graph below.**

Picture Post Animation

This animation shows 4 years of picture post imagery, as well as a corresponding calculated greenness index and satellite data.
Satellite data are from the MODIS (MODerate-resolution Imaging Spectroradiometer) satellite, and include the Normalized Difference Vegetation Index (NDVI, measures 'greenness') and albedo***.
