Modeling broader effects of wildfires in Siberia

As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.

Researchers develop forest extent map for Mexico

To properly protect forests and evaluate the state of natural resources, conservation practices and environmental policies, it is important to have accurate information on an area's forest extent.
