#Trees are methane sinks

"Our paper details how we examined in situ woody surface (bark) methane exchange in upland tropical, temperate and boreal forest trees. [...] Sometimes we found a little methane emitted from the tree bases, but the higher up the tree we went, (> 1m above the forest floor) we observed something unexpected: Methane uptake from the atmosphere resulting in a net tree methane sink.

[...] Ultimately these procedures allow us to suggest that trees may contribute 24.6-49.9 Tg of atmospheric methane uptake globally. Similar in size to the only other land-based sink that we know of. And when taking these numbers for upland forest, we established that trees maybe 7% (temperate forest) to 12% (Tropics) better for climate than we’ve previously given them credit for."
