Here, we highlight seven assisted restoration innovations with demonstrated local-scale results that, once upscaled, hold promise to rapidly regenerate forests. We comprehensively assessed how each approach facilitated forest, woodland, and/or mangrove recovery across 143 studies. Our results reveal techniques with a marked ability to catalyze vegetation recovery compared to “business-as-usual” approaches. However, the context-dependent cost-benefit ratio and feasibility of applying particular approaches requires careful consideration.

We leverage satellite observations to explore the variability of glacier albedo and understand its sensitivity to potential drivers and its future evolution. We find that glacier albedo has declined during 2001–2020, but high interannual variability is also an important signal. These variations are highly sensitive to air temperature and snow conditions and to nearby dust/black carbon emission sources. Future changes to these drivers will lead to further decreases of 2.9%–12.5% in glacier albedo by 2100 under different warming scenarios.

For many mountains worldwide, forest loss appears to occur disproportionately at lower elevations. This pattern—if confirmed—means widespread loss and scarcity of lower-elevation forest habitat, with profound biodiversity implications within and beyond these elevations. However, there remains no global assessment of this pattern based on robustly mapped forest loss, crucially by disentangling forest loss from the natural absence of forest. We fill this gap and demonstrate disproportionate forest loss at lower elevations for >65% of all 769 mountains in the world’s forested ecoregions that we assessed. We find a clear lack of lower-elevation forest—most of which remains unprotected—and associated warmer and drier climatic conditions, explainable by high human impacts and low precipitation at these elevations.

Here, we illustrate that conservation through protected areas can effectively preserve forest productivity and carbon capture, which depend on tree diversity. However, failing to mitigate climate change diminishes the effectiveness of these areas, especially in warmer biomes. Even with optimal protected area selection, preserving tree diversity-dependent productivity could be compromised without significant climate change mitigation.
