While it is well established that biodiversity increases ecosystem productivity, its influence on long-term changes in photosynthesis remains unclear. Here we integrate a high-resolution map of tree species richness with satellite-derived photosynthesis proxies during 2001–2020 to show that high richness not only enhances current levels of photosynthesis but also correlates with a greater increase in photosynthesis over time. This pattern is largely driven by an amplified CO2 fertilization effect (CFE) in species-rich forests. The ability of diverse forests to mitigate water and nutrient limitations probably contributes to the CFE enhancement and photosynthesis rise. Projections suggest that biodiversity losses by 2050 could reduce photosynthesis trends by 3–17%, representing a cumulative forest photosynthesis loss of 4.4–35.7 PgC. These findings underscore the critical need to integrate biodiversity conservation into climate mitigation strategies to safeguard the terrestrial carbon sink. The authors integrate tree species richness with satellite-derived photosynthesis proxies to show that richness correlates with greater current levels of photosynthesis and greater increases over time. Projected biodiversity loss by 2050 could lead to cumulative forest photosynthesis loss of 4.4–35.7 PgC.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 8","pages":"980-988"},"PeriodicalIF":26.9,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148612646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, using a process-based model to compare seasonal thaw depths under forested and bare-ground scenarios, we quantify distinct canopy thermal insulation capacities of deciduous needleleaf, evergreen needleleaf and deciduous broadleaf canopies on permafrost thermal dynamics. Canopy buffering maintains approximately 59 Pg of carbon in a frozen state, which equals 32% of the total forested permafrost carbon pool and far exceeds boreal biomass stocks (7–19 Pg). Canopy changes could mobilize this frozen SOC through gradual thaw (40 Pg) and rapid thermokarst collapse (19 Pg). While forest loss sacrifices biomass carbon stocks, resulting thaw would expose orders of magnitude more SOC from previously frozen reservoirs, revealing a critical asymmetry. Forest conservation strategies in continuous permafrost zones must account for canopy-mediated thermal protection of frozen SOC, which far exceeds its biomass carbon sequestration capacity. Soil carbon stocks are greater than biomass carbon in boreal forests. This study shows that tree canopies thermally protect more carbon in permafrost from thaw than is stored in biomass, highlighting the need to consider carbon impacts of forest disturbance and conservation on an ecosystem scale.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 8","pages":"971-979"},"PeriodicalIF":26.9,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41558-026-02692-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148612645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Models exhibit diverse long-term responses to the cessation of CO2, including additional multi-century warming. Here we analytically predict this post-cessation temperature change, known as the zero emissions commitment (ZEC), from three climate metrics: the airborne fraction of cumulative CO2 emissions, transient climate response and equilibrium climate sensitivity. Constraining these metrics implies a near-zero multi-century ZEC from historical CO2 emissions. Net-zero GHG policies, however, differ from idealized CO2 cessation by targeting the aggregate effect of multiple GHGs and relying on CO2 removal to offset residual emissions. To capture these policy-relevant effects, we introduce the net-zero emissions commitment (Net-ZEC). Across scenarios and offsetting conventions, Net-ZEC implies a multi-century cooling of at least 0.6 °C following net-zero GHG emissions. How global temperatures change after net-zero emissions are reached is highly uncertain. Here the authors constrain this response and find that net-zero GHG emissions lead to multi-century cooling of at least 0.6 °C.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"16 8","pages":"941-946"},"PeriodicalIF":26.9,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148587382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
