Forest age can determine the capacity of a forest to uptake carbon from the atmosphere. Yet, a lack of global diagnostics that reflect the forest stage and associated disturbance regimes hampers the quantification of age-related differences in forest carbon dynamics. In this paper, we introduced a new global distribution of forest age inferred from forest inventory, remote sensing and climate data in support of a better understanding of the global dynamics in the forest water and carbon cycles.

Forest disturbances are difficult to predict in models because they occur randomly. We discovered that the long-term rules of disturbance known as
regimeleave a unique footprint in a forest's spatial biomass patterns. We trained a model on millions of computer simulations to learn this link. By applying this model to detailed satellite biomass, we could read these patterns to infer the disturbance regime globally, helping make climate projections more accurate.

In this study, we model the canopy height of woody vegetation across Europe at a spatial resolution of 10 m for the year 2020, using Copernicus Sentinel-1 and Sentinel-2 data. In addition, an independent validation dataset based on airborne LiDAR data — comprising about 3,700 patches of 640 × 640 m distributed across Europe — has been prepared. Comparisons with existing publicly available canopy height products indicate that our estimates are competitive with other canopy height datasets.

We evaluated Global Navigation Satellite System (GNSS) signals to monitor forest water storage, helping to close an important observational gap in plant hydraulics and micrometeorology at stand-scale. We show that signal losses in the canopy are strongly linked to three-dimensionally modeled rainfall interception. However, detecting subtle fluxes, such as internal water dynamics, dew and intercepted light rain is inhibited by signal noise, and the hydraulics properties of the ecosystem.

The Amazon forest is important for carbon storage, but climate change might push parts of it towards a tipping point into a degraded state. By studying satellite trends and tree diversity across different spatial scales, we found a larger tipping risk at smaller spatial scales than for the whole region. We also found that higher tree diversity makes the forest more stable and thus less likely to tip, although the effect is relatively weak, highlighting the importance of protecting biodiversity.

By analysing 30 years of satellite SAR (Synthetic Aperture Radar) data, we have found that the number of glacier surges over Svalbard has tripled since 2015. We show that this increase is unlikely to be explained solely by improvements in data quality or by random fluctuations in surge frequency, suggesting that this trend is caused by an external forcing mechanism. Given our incomplete understanding of surge initiation, the cause of the observed threefold increase remains however uncertain.

We created the LULUCF Data Hub to make information on how land use affects carbon dioxide emissions and removals more transparent and comparable among datasets. We show country-level data from national reports and global sources, allowing users to explore differences and similarities in land-based carbon fluxes. It helps identify where data agree, where they differ, and where more research is needed.

This paper presents a unique global reference data set for land cover mapping at a 10 m resolution, aligned with Sentinel-2 imagery for the year 2015. It contains more than 16.5 million data records at a 10 m resolution (or 165 K data records at 100 m) and information on 12 different land cover classes. The data set was collected by a group of experts through visual interpretation of very high resolution imagery, along with other sources of information provided in the Geo-Wiki platform.

Europe's forests are undergoing complex changes in response to increasing disturbances driven by climate and land use changes. Here, we present the European Forest Disturbance Atlas, a satellite-based approach for mapping annual forest disturbances across continental Europe from 1985 onwards. Maps provide insights into the year of disturbance occurrence, the actual frequency of disturbances, severity and the underlying causal agent, thus contributing to a future monitoring system envisioned for Europe.

The pan-boreal lightning-ignited wildfire (BoLtFire) dataset spans the entire boreal forest from 2012 to 2022, focusing on fires of at least 200 ha. Developed using a new methodology to match lightning to wildfires in the boreal region, it includes 6902 fires – 4201 in Eurasia and 2701 in North America. BoLtFire provides new opportunities to model the ignition and spread dynamics of boreal wildfires and offers deeper insights into lightning-driven fire activity globally.

Updated global maps of greenhouse gas (GHG) emissions and sequestration by forests from 2001 onwards using satellite-derived data show that forests are strong net carbon sinks, capturing about as much CO2 each year on average as the USA emitted from fossil fuels in 2019. After reclassifying fluxes to countries’ reporting categories for national GHG inventories, we found that roughly two-thirds of the net CO2 flux from forests is anthropogenic and one-third is non-anthropogenic.

This study examines the multi-annual meteorological history of low-forest-greenness events in Europe's temperate and Mediterranean biome in 2002–2022. We systematically identify anomalies in temperature, precipitation, and weather systems as event precursors, with noteworthy differences between the two biomes. We also quantify the impact of the most extensive event in 2022 (37 % coverage), underlining the importance of understanding the forest–meteorology interaction in a changing climate.

Europe was affected by an extreme drought in 2018. We show that this drought has increased forest disturbances across Europe, especially central and eastern Europe. Disturbance levels observed 2018–2020 were the highest on record for 30 years. Increased forest disturbances were correlated with low moisture and high atmospheric water demand. The unprecedented impacts of the 2018 drought on forest disturbances demonstrate an urgent need to adapt Europe’s forests to a hotter and drier future.

Roots play a key role in our Earth system. Here we combine 10 307 field measurements of forest root biomass worldwide with global observations of forest structure, climatic conditions, topography, land management and soil characteristics to derive a spatially explicit global high-resolution (~ 1 km) root biomass dataset. In total, 142 ± 25 (95 % CI) Pg of live dry-matter biomass is stored belowground, representing a global average root : shoot biomass ratio of 0.25 ± 0.10.

Editorial statement
European forests are an important carbon sink, but this sink and the carbon stocks that these forests contain are at risk from biotic disturbances and extreme events. Besnard and others use observations of forest changes to show that older and more carbon rich forests are disproportionately impacted by these events and are projected to become even more susceptible, emphasizing the role of proactive management to ensure forest resilience and diversity.

Short summary
Europe’s forests store vast amounts of carbon, but climate-driven disturbances are becoming more frequent. By combining satellite records with information on forest age and structure, we show that recent disturbances increasingly affect the oldest and most carbon-rich forests, particularly spruce forests in Central Europe. This emerging pattern puts long-accumulated carbon at risk and may reduce the long-term climate benefits provided by Europe’s forests.
