SNIP: Protecting forest ecosystems is critical in the fight to limit global warming — when forests are disturbed they release carbon, but when left to grow they actively pull carbon out of the air and store it. When left standing, forests also provide optimal natural protection against extreme weather events, like flooding and droughts.
Many people are aware of the importance of protecting rainforests in Brazil to help mitigate climate change, but few realize that more logging occurs in the US, and more wood is consumed here, than in any other nation globally. The rate and scale of logging in the Southeastern US alone is four times that in South American rainforests.
The Trump Administration and industry have been aggressively promoting misinformation about forests and wildland fires, while advocating for large increases in logging under the guises of “forest health,” “fuel reduction,” “renewable energy,” and reducing carbon emissions.
But the promotion of logging to supposedly curb carbon emissions is just part of the Administration’s ongoing alignment with industry and troubling pattern of climate science denial. Carbon emissions from logging in the US are ten times higher than the combined emissions from wildland fire and tree mortality from native bark beetles. Fire only consumes a minor percentage of forest carbon, while improving availability of key nutrients and stimulating rapid forest regeneration. Within a decade after fire, more carbon has been pulled out of the atmosphere than was emitted. When trees die from drought and native bark beetles, no carbon is consumed or emitted initially, and carbon emissions from decay are extremely small, and slow, while decaying wood helps keeps soils productive, which enhances carbon sequestration capacity over time.
On the other hand, industrial logging — even when conducted under the euphemism of “thinning” — results in a large net loss of forest carbon storage, and a substantial overall increase in carbon emissions that can take decades, if not a century, to recapture with regrowth. Logging also tends to make fires burn faster and more intensely while degrading a forest ecosystem’s ability to provide natural protections against extreme weather events.
