Seasonal compensation implied no weakening of the land carbon sink in the Northern Hemisphere under the 2015/2016 El Niño
The recurrent extreme El Niño events are commonly linked to reduced vegetation growth and the land carbon sink over many but discrete regions of the Northern Hemisphere (NH). However, we reported here a pervas...

Asymmetric influence of forest cover gain and loss on land surface temperature
The direct biophysical effects of fine-scale tree cover changes on temperature are not well understood. Here, we show how land surface temperature responds to subgrid gross tree cover changes. We find that in ...

Universal temperature sensitivity of denitrification nitrogen losses in forest soils
Soil nitrous oxide (N2O) and dinitrogen (N2) emissions from denitrification are crucial to the nitrogen (N) cycle. However, the temperature sensitivities (Q10) of gaseous N losses in forest soils are poorly under...

Open AccessOverestimated nitrogen loss from denitrification for natural terrestrial ecosystems in CMIP6 Earth System Models
Denitrification and leaching nitrogen (N) losses are poorly constrained in Earth System Models (ESMs). Here, we produce a global map of natural soil 15N abundance and quantify soil denitrification N loss for glob...

Open AccessRecent intensification of wetland methane feedback
The positive response of wetland methane (CH4) emissions to climate change is an important yet uncertain Earth-system feedback that amplifies atmospheric CH4 concentrations. Here, using a wetland model, we report...

Open AccessHalf-millennium evidence suggests that extinction debts of global vertebrates started in the Second Industrial Revolution
Extinction debt describes the time-lagged process of species extinction, which usually requires dozens to hundreds of years to be paid off. However, due to the lack of long-term habitat data, it is indetermina...

Wetland emission and atmospheric sink changes explain methane growth in 2020
Atmospheric methane growth reached an exceptionally high rate of 15.1 ± 0.4 parts per billion per year in 2020 despite a probable decrease in anthropogenic methane emissions during COVID-19 lockdowns1. Here we qu...

Open AccessEarlier ice loss accelerates lake warming in the Northern Hemisphere
How lake temperatures across large geographic regions are responding to widespread alterations in ice phenology (i.e., the timing of seasonal ice formation and loss) remains unclear. Here, we analyse satellite...

Open AccessEcoenzymatic stoichiometry reveals widespread soil phosphorus limitation to microbial metabolism across Chinese forests
Forest soils contain a large amount of organic carbon and contribute to terrestrial carbon sequestration. However, we still have a poor understanding of what nutrients limit soil microbial metabolism that driv...

Open AccessGridded maps of wetlands dynamics over mid-low latitudes for 1980–2020 based on TOPMODEL
Dynamics of global wetlands are closely linked to biodiversity conservation, hydrology, and greenhouse gas emissions. However, long-term time series of global wetland products are still lacking. Using a diagno...

Open AccessTrade-off between tree planting and wetland conservation in China
Trade-offs between tree planting programs and wetland conservation are unclear. Here, we employ satellite-derived inundation data and a process-based land surface model (ORCHIDEE-Hillslope) to investigate the ...

Open AccessA global map of planting years of plantations
Plantation is an important land use type that differs from natural forests and affects the economy and the environment. Tree age is one of the key factors used to quantify the impact of plantations. However, t...

Open AccessRetention of deposited ammonium and nitrate and its impact on the global forest carbon sink
The impacts of enhanced nitrogen (N) deposition on the global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly ...

Fire enhances forest degradation within forest edge zones in Africa
African forests suffer from severe fragmentation that further causes forest degradation near forest edges. The impact of fires used for slash-and-burn on forest edge effects remains unclear. Here, using high-r...

Open AccessClimate warming from managed grasslands cancels the cooling effect of carbon sinks in sparsely grazed and natural grasslands
Grasslands absorb and release carbon dioxide (CO2), emit methane (CH4) from grazing livestock, and emit nitrous oxide (N2O) from soils. Little is known about how the fluxes of these three greenhouse gases, from m...

Future impacts of climate change on inland Ramsar wetlands
The 1971 Ramsar Convention promotes wetland conservation worldwide, yet climate change impacts on wetland extent and associated biodiversity are unclear. Hydrological modelling and soil moisture estimates are ...

Open AccessGlobal terrestrial carbon fluxes of 1999–2019 estimated by upscaling eddy covariance data with a random forest
The terrestrial biosphere is a key player in slowing the accumulation of carbon dioxide in the atmosphere. While quantification of carbon fluxes at global land scale is important for mitigation policy related ...

Temporal trade-off between gymnosperm resistance and resilience increases forest sensitivity to extreme drought
The frequency and intensity of droughts have increased over the decades, leading to increased forest decline. The response of forest to drought can be evaluated by both its sensitivity to drought (resistance) ...
