Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(8/8) Also see the short piece we wrote for @theconversation.com here: theconversation.com/we-discovere...theconversation.comWe discovered microbes in bark ‘eat’ climate gases. This will change the way we think about treesWe already knew forests were heavy lifters in reducing climate pollution. New research reveals the tiny microbes in tree bark can also “eat” climate gases. 031
Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(7/8) Bottom line: trees aren’t just carbon stores.

Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(6/8) These systems are dynamic. Under low-oxygen conditions inside bark, some microbes can switch to producing methane or hydrogen — meaning climate change (e.g. flooding, warming) could alter these processes... 110
Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(5/8) Why this matters: the global surface area of tree bark is immense — comparable to Earth’s land surface!! This points to a previously unrecognised, large-scale atmospheric sink.

Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(4/8) Our lab and field experiments show bark microbes can remove multiple climate-relevant gases from the atmosphere, with particularly strong uptake and affinity for hydrogen. 100
Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(3/8) These bark microbes aren’t just living there — they’re active. Many use trace gases like #Hydrogen (H₂), #Methane (CH₄), and #CarbonMonoxide (CO) as #Carbon and energy sources.🦠 100
Dr. Luke Jeffrey @jeffrethane.bsky.social · 13/01/2026(2/8) Across 8 common Australian tree species (paperbarks, eucalypts, acacias, mangroves & more), bark contains trillions of microbial cells per m² — distinctly unique from soil or water communities. 100
