Mission and Vision

What Drives Us Forward

Terraffirm was established to address the social and economic disruption that will be caused by an increase in average global temperature resulting from the increased greenhouse effect caused primarily by the burning of fossil fuels. This disruption will take the form of rising sea level, more frequent and more intense heat waves and wildfires, changes in rainfall patterns, and, likely, more intense storms.


To this end, we conduct and fund research, development, and educational and advocacy activities to bring about awareness of global climate change and and to mitigate its effects. We are focused on methods of carbon sequestration that are scalable and cost-effective.

Carbon Sequestration 

Carbon captured in plants or trees by photosynthesis is typically released back into the atmosphere over time, either by decomposition or by burning. We are investigating ways to substantially slow this return of carbon to the atmosphere by increasing the amount and recalcitrance of soil organic carbon, by wood burial, or by improved techniques of managing the decomposition of slash piles created during forest thinning operations.

Extreme Wildfires

In the Western United States, the main cause of the increased risk and extent of wildfires is climate change.  A number of factors influence the risk of wildfires, including the moisture content of the soil, the air temperature, and the presence and dryness of potential fuel such as trees and shrubs. All these factors are strongly affected, either directly or indirectly, by climate change, which causes forest fuels to be drier.
