Live woody vegetation is the largest reservoir of biomass carbon, with its restoration considered one most effective natural climate solutions. However, terrestrial carbon fluxes remain uncertainty in global cycle. Here, we develop spatially explicit estimates stock changes live from 2000 to 2019 using measurements ground, air, and space. We show that has removed 4.9 5.5 PgC year −1 atmosphere, offsetting 4.6 ± 0.1 gross emissions disturbances adding substantially (0.23 0.88 ) stocks. Gross removals tropics were four times larger than temperate boreal ecosystems combined. Although responsible for more 80% fluxes, soil, dead organic matter, lateral transport may play important roles sink.

Maintaining the abundance of carbon stored aboveground in Amazon forests is central to any comprehensive climate stabilization strategy. Growing evidence points indigenous peoples and local communities (IPLCs) as buffers against large-scale emissions across a nine-nation network territories (ITs) protected natural areas (PNAs). Previous studies have demonstrated link between land management avoided deforestation, yet few accounted for forest degradation disturbances-processes that occur without clearing but are increasingly important drivers biomass loss. Here we provide accounting dynamics inside outside lands. Using published data on changes density cover, track gains losses from conversion degradation/disturbance. We find ITs PNAs more than one-half (58%; 41,991 MtC) region's 2016 were responsible just 10% (-130 net change (-1,290 MtC). Nevertheless, nearly billion tons lost both (-434 MtC -423 MtC, respectively), with degradation/disturbance >75% 7 countries. With deforestation increasing, neglected significant source region-wide (47%), our results suggest sustained support IPLC stewardship critical. IPLCs global environmental service merits increased political protection financial support, particularly if Basin countries achieve their commitments under Paris Climate Agreement.

Abstract Forest disturbance regimes are expected to intensify as Earth’s climate changes. Quantifying forest vulnerability disturbances and understanding the underlying mechanisms is crucial develop mitigation adaptation strategies. However, observational evidence largely missing at regional continental scales. Here, we quantify of European forests fires, windthrows insect outbreaks during period 1979–2018 by integrating machine learning with data satellite products. We show that about 33.4 billion tonnes biomass could be seriously affected these disturbances, higher relative losses when exposed (40%) fires (34%) compared (26%). The spatial pattern in strongly controlled interplay between characteristics background climate. Hotspot regions for located borders envelope, both southern northern Europe. There a clear trend overall driven warming-induced reduction plant defence outbreaks, especially high latitudes.
