When soil moisture (SM) content falls within a transitional regime between dry and wet conditions, it controls evaporation, affecting atmospheric heat humidity. Accordingly, different SM regimes correspond to gears of land-atmosphere coupling, climate. Determining patterns their future evolution is imperative. Here, we examine global distributions from ten climate models. Under increasing CO2, the range extends into unprecedented coupling in many locations. Solely areas decline globally by 15.9%, while emerge currently humid tropics high latitudes. Many semiarid regions spend more days fewer regime. These imply that larger fraction world will evolve experience multiple with strongly coupled expanding most. This could amplify sensitivity feedbacks land management.

Abstract During extensive periods without rain, known as dry-downs, decreasing soil moisture (SM) induces plant water stress at the point when it limits evapotranspiration, defining a critical SM threshold (θ crit ). Better quantification of θ is needed for improving future projections climate and resources, food production, ecosystem vulnerability. Here, we combine systematic satellite observations diurnal amplitude land surface temperature (dLST) during corroborated by in-situ data from flux towers, to generate observation-based global map . We find an average 0.19 m 3 /m , varying 0.12 in arid ecosystems 0.26 humid ecosystems. simulated Earth System Models overestimated dry areas underestimated wet areas. The observed pattern reflects adaptation available atmospheric demand. Using explainable machine learning, show that aridity index, leaf area texture are most influential drivers. Moreover, annual fraction days with stress, stays below has increased past four decades. Our results have important implications understanding inception models identifying tipping points.

Across western North America (WNA), 20th-21st century anthropogenic warming has increased the prevalence and severity of concurrent drought heat events, also termed hot droughts. However, lack independent spatial reconstructions both soil moisture temperature limits potential to identify these events in past place them a long-term context. We develop Western American Temperature Atlas (WNATA), data-independent 0.5° gridded reconstruction summer maximum temperatures back 16th century. Our evaluation WNATA with existing hydroclimate reveals an increasing association between recent decades, relative five centuries. The synthesis paleo-reconstructions indicates that amplification modern WNA megadrought by frequency extent compound dry conditions 21st are likely unprecedented since at least

Scientific innovation is overturning conventional paradigms of forest, water, and energy cycle interactions. This has implications for our understanding the principal causal pathways by which tree, vegetation cover (TFVC) influence local global warming/cooling. Many identify surface albedo carbon sequestration as TFVC affects Moving toward outer latitudes, in particular, where snow more important, effects are perceived to overpower sequestration. By raising albedo, deforestation thus predicted lead cooling, while increasing forest assumed result warming. Observational data, however, generally support opposite conclusion, suggesting poorly understood. Most accept that temperatures influenced interplay incoming shortwave (SW) radiation, partitioning remaining, post-albedo, SW radiation into latent sensible heat. However, extent avoidance heat formation first foremost mediated presence (absence) water not well both mediates availability on land drives potential production (evapotranspiration, ET). While directly linked than cooling/warming, it driven photosynthesis powers additional cloud top-of-cloud reflectivity, drive cooling. loss reduces storage, precipitation recycling, downwind rainfall potential, driving reduction ET (latent heat) formation. reducing heat, formation, precipitation, warming (sensible formation), further diminishes growth (carbon sequestration). Large-scale tree restoration could, therefore, contribute significantly temperature cooling through

Abstract Europe has experienced severe drought events in recent decades, posing challenges to understand vegetation responses due diverse distribution, varying growth stages, different characteristics, and concurrent hydroclimatic factors. To analyze response meteorological drought, we employed multiple indicators across European biomes. Our findings reveal that sensitivity increases as the canopy develops throughout year, with sensitivities from −0.01 spring 0.28 autumn drought-susceptible areas 18.5 57.8% Europe. Soil water shortage exacerbates vegetation-drought temporally, while its spatial impact is limited. Vegetation-drought strongly correlates vapor pressure deficit partially atmospheric CO 2 concentration. These results highlight spatiotemporal variations influence of The enhance our understanding factors, providing valuable sub-seasonal information for management preparedness.
