Carbon release through boreal fires could considerably accelerate Arctic warming; however, fire occurrence mechanisms and dynamics remain largely unknown. Here, we analyze activity relevant large-scale atmospheric conditions over southeastern Siberia, which has the largest burned area fraction in circumboreal high-level carbon emissions due to high-density peatlands. It is found that annual increased when a positive Oscillation (AO) takes place early months of year, despite peak season...
Abstract Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate interactions in rapidly changing Arctic, uncertainties their prediction persist. Here, we harmonize SEB observations across a network vegetated and glaciated sites at circumpolar scale (1994–2021). Our variance-partitioning analysis identifies vegetation type as an important predictor SEB-components during Arctic summer (June-August), compared to other SEB-drivers including climate, latitude...
Abstract Accurate representation of the Atlantic Meridional Overturning Circulation (AMOC) in global climate models is crucial for reliable future predictions and projections. In this study, we used 42 coupled atmosphere–ocean to analyze low-frequency variability AMOC driven by North Oscillation (NAO). Our results showed that influence simulated NAO on differs significantly between models. We large intermodel diversity originates from diverse oceanic mean state, especially over subpolar...
Abstract Stomatal closure is one of the main physiological responses to increasing CO 2 concentration, which leads a reduction in plant water loss. This response has potential trigger changes climate system by regulating surface energy budgets—a phenomenon known as forcing. However, its remote impacts on Arctic are unclear. Here we show that vegetation at high latitudes enhances amplification via and time-delayed forcing processes. Surface warming occurs mid-to-high due acclimation-induced...
Abstract Better understanding of factors that control the global carbon cycle could increase confidence in climate projections. Previous studies found good correlation between growth rate atmospheric CO2 concentration and El Niño–Southern Oscillation (ENSO). The increases during Niño but decreases La Niña. In this study, long-term simulations Earth system models (ESMs) phase 5 Coupled Model Intercomparison Project archive were used to examine interannual flux variability associated with...
The El Niño/Southern Oscillation (ENSO) drives interannual variation in the global carbon cycle. However, relationship between ENSO and cycle can be modulated by climate change due to anthropogenic forcing. We show herein that sensitivity of terrestrial flux will enhanced under greenhouse warming 44% ( ± 15%), indicating a future amplification carbon-climate interactions. Separating contributions changes reveals response land surface temperature gross primary production local are...
Abstract Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use Earth System Model analyse response in Arctic temperatures radiative applied under representative concentration pathway 8.5 decrease that achieved 4.5. The three methods Stratospheric Aerosol Injection, Marine Cloud Brightening, and Cirrus Thinning, mitigate global mean temperature rise, however, our...
Abstract Indian Ocean Dipole (IOD), a major climate variability in the tropics which drives abiotic stress associated with heavy rainfalls and severe droughts, is not much understood terms of its role carbon cycle, while El Niño‐Southern Oscillation (ENSO)‐related terrestrial cycle variation has been intensively studied. Here, we investigate IOD's impact on land photosynthesis over ocean rim countries during austral spring using satellite‐based gross primary productivity (GPP) Earth System...
Abstract Spring and summer vegetation productivity in Siberia shows opposing responses to warmer spring. warming causes excessive growth earlier start of photosynthesis, enhancing However, this leads reduced the following season (i.e., summer) through soil moisture depletion. To understand how an exceptional spring heatwave (HW) affected ecosystem carbon uptake, we investigated spatiotemporal cascade gross primary production (GPP) multiple climate variables over 2020, using a...
Vegetables are full of nutrients that difficult to obtain from meat or grains, such as vitamins, minerals, and dietary fiber, but they vulnerable abiotic stress, making it consistent yields. Climate extreme events have caused a decline in vegetable production, often leading elevated prices. Here, we investigate how climatic factors influence price changes China, focusing on colder months when weather impacts more pronounced. We found three major patterns consumer index (VCPI) data, including...
Urbanization induces complex interactions between socioeconomic activities and environmental changes, as reflected in the increase of Night-Time Light (NTL) decline Fractional Vegetation Cover (FVC). While NTL is a key indicator economic growth infrastructure expansion, its concurrent association with vegetation loss exacerbates urban heat island (UHI) effects. Although substantial progress has been achieved examining individual impact urbanization on land surface temperature (LST), studies...

Abstract The global mean temperature is increasing due to the increase in greenhouse gases atmosphere, but paradoxically, many regions mid-latitudes have experienced cold winters recently. Here we analyse multiple observed and modelled datasets evaluate links between Arctic variation damage East Asian terrestrial ecosystem. We find that winter warming over Barents-Kara Sea has led simultaneous negative anomalies most areas Asia leaf area index southern China where mostly subtropical...
Abstract Fire activity in Equatorial Asia shows large interannual variability. Teleconnections by El Niño‐Southern Oscillation and Indian Ocean Dipole are linked to drought fire events; however, we found here that significant role of local Sea Surface Temperature (SST) over the Banda variability Asian burned area October even after removing linear effects teleconnections. is transient period from dry wet season strengthened seasonal circulation leads a negative SST anomaly through...
The terrestrial ecosystem in East Asia mainly consists of semi-arid regions that are sensitive to climate change. Therefore, gross primary productivity (GPP) could be highly variable and vulnerable change, which can significantly affect the local carbon budget. Here, we examine spatial temporal characteristics GPP variability its relationship with factors over last three decades. We detect an abrupt decrease Eastern China-Mongolia region around year 2000. This is attributed precipitation...
Extensive studies claimed that the central equatorial Pacific (CP) El Niño has occurred more frequently and strongly than eastern in recent years. To explain this phenomenon, spatial patterns principal component time series from several sea surface temperature (SST) data sets tropical are analyzed for period of 1951–2010. Cyclostationary empirical orthogonal function analysis separates two modes SST variability, which about 50% 10% total respectively. Their temporal similar among different...
Abstract The El Niño–Southern Oscillation (ENSO) drives variations in terrestrial carbon fluxes by affecting the ecosystem via atmospheric teleconnections and thus plays an important role interannual variability of global cycle. However, we lack such knowledge on decadal time scales, that is, how cycle can be affected ENSO characteristics. Here examine how, much, affects analyzing a 1,801‐year preindustrial control simulation. We identify two different aspects, together explaining ~36%...
Mechanisms by which tropical Pacific and Indian Ocean sea surface temperatures (SST) influence vegetation in eastern Africa have not been fully explored. Here, we use a suite of idealized Earth system model simulations to elucidate the governing processes for African interannual changes. Our analysis focuses on Tanzania. In absence ENSO-induced temperature anomalies Tropical (TIO), El Niño causes during its peak phase negative precipitation over Tanzania due weakening tropical-wide Walker...
