Loss of moist broadleaf forest in Africa has turned a carbon sink into source

Africa’s forests just got a grim status update: once a carbon sponge soaking up planet-warming gas, they’ve flipped to a carbon source between 2010–2017. The study leans on new satellite maps (think lasers and radar + machine learning) and pins the main culprit on deforestation in tropical moist broadleaf forests, with some savanna shrubs trying (and failing) to balance the books. Cue the comments turning into a climate therapy session. One camp went full existential: “profit over survival” and end-of-species vibes, with users posting the “This is fine” dog surrounded by flames. Another camp brought receipts, linking Finland’s forests also flipping to source, like, this isn’t just an Africa problem — see this post. Then the nerd fight broke out: does losing aboveground biomass automatically mean more carbon in the air? One user argued logging removes wood without instant emissions, sparking a thread on what happens to felled trees (burned, rotting, furniture, firewood). Meanwhile, a viral quip compared humans to bacteria overrunning a petri dish. The policy talk? The study calls for tougher anti-deforestation goals and stronger Paris Agreement pledges, but the crowd is split between doom, data skepticism, and global déjà vu.
