This planetary boundaries framework update finds that six of the nine are transgressed, suggesting Earth is now well outside safe operating space for humanity. Ocean acidification close to being breached, while aerosol loading regionally exceeds boundary. Stratospheric ozone levels have slightly recovered. The transgression level has increased all earlier identified as overstepped. As primary production drives system biosphere functions, human appropriation net proposed a control variable...
Abstract Human actions compromise the many life-supporting functions provided by freshwater cycle. Yet, scientific understanding of anthropogenic change and its long-term evolution is limited. Here, using a multi-model ensemble global hydrological models, we estimate how, over 145-year industrial period (1861–2005), streamflow soil moisture have deviated from pre-industrial baseline conditions (defined 5th–95th percentiles, at 0.5° grid level monthly timestep 1661–1860). Comparing two...
Abstract Several safe boundaries of critical Earth system processes have already been crossed due to human perturbations; not accounting for their interactions may further narrow the operating space humanity. Using expert knowledge elicitation, we explored among seven variables representing relevant food production, identifying many little in literature. We found that green water and land change affect other strongly, while land, freshwater ocean components biosphere integrity are most...
Abstract The planetary boundaries framework defines a safe operating space for humanity. To date, these have mostly been investigated separately, and it is unclear whether breaching one boundary can lead to the transgression of another. By employing dynamic global vegetation model, we systematically simulate strength direction effects different levels climate change (using output from ten phase 6 Coupled Model Intercomparison Project models CO 2 ranging 350 ppm 1000 ppm). We focus on...
<p>Green water - i.e., land precipitation, evaporation and soil moisture is fundamental for the functioning of biosphere Earth System, but increasingly perturbed by continental-to-planetary scale human pressures on land, climate systems. The planetary boundaries (PB) framework demarcates a global safe operating space humanity, does hitherto not explicitly account green water. Here, we propose green-water boundary within existing PB framework, which control variable could be...
Abstract. Human activities have had a significant impact on Earth's systems and processes, leading to transition of state from the relatively stable Holocene epoch Anthropocene. The planetary boundary framework characterizes major risks destabilization, particularly in core dimensions climate biosphere change. Land system change, including deforestation urbanization, alters ecosystems impacts water energy cycle between land surface atmosphere, while change can disrupt balance vegetation...

Abstract Several safe boundaries of critical Earth system processes have already been crossed by human perturbations. Recent research indicates that not accounting for the interactions between these may further narrow operating space humanity. Yet existing work accounts only transgression single and a few studies take some boundary into account. For future sustainability assessments, it is essential to understand transgressions their more comprehensively. Here, we explore quantitatively how...
