Despite expected increase in terrigenous inputs to the Arctic Ocean, their impacts on biogeochemical cycles are currently largely neglected in IPCC-like models. Here we used a state-of-the-art high-resolution ocean biogeochemistry model that includes carbon and nutrient inputs from rivers and coastal erosion to produce twenty-first-century pan-Arctic projections. Surprisingly, even with an anticipated rise in primary production across a wide range of emission scenarios, our findings indicate that climate change will lead to a counterintuitive 40% reduction in the efficiency of the Arctic’s biological carbon pump by 2100, to which terrigenous inputs contribute 10%. Terrigenous inputs will also drive intense coastal CO2 outgassing, reducing the Arctic Ocean’s carbon sink by at least 10% (33 TgC yr−1). These unexpected reinforced feedback, mostly due to accelerated remineralization rates, lower the Arctic Ocean’s capacity for sequestering carbon. Changes in the Arctic could impact the oceanic carbon sequestration of the region. Here the authors consider regional biogeochemistry, including coastal erosion and river inputs, to show a 40% reduction in the biological carbon pump to 2100 under climate change.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 2","pages":"171-179"},"PeriodicalIF":29.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-024-02233-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929428","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}

Although trends in Arctic sea ice thickness and concentration are well documented, changes in ridge morphology remain unclear. This study provides airborne-based evidence of a shift towards a smoother ice surface, with fewer pressure ridges and reduced surface drag, attributed to the loss of old ice. Furthermore, an increase in seasonal ice cover enhances overall deformation in the Arctic and acts as a negative feedback mechanism on pan-Arctic ridge morphology: the greater the proportion of seasonal ice, the higher the pan-Arctic mean ridge rate, dampening an overall decline in ridges with age. While thinner and less frequent ridges benefit industries such as shipping, these changes are likely to have profound impacts on the energy and mass balance and the ecosystem of the Arctic Ocean. Pressure ridges, a characteristic feature of Arctic sea ice, play an important role in the ecosystem but pose challenges to shipping. Here the authors use aircraft measurements to document a decline in both the frequency and height of these pressure ridges in recent decades.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 1","pages":"66-72"},"PeriodicalIF":29.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-024-02199-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929789","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}

For decades following its introduction in 1869, the spongy moth (Lymantria dispar) severely defoliated North American forests, but the introduction of the fungal pathogen Entomophaga maimaiga in 1989 suppressed spongy moth defoliation for 27 years. E. maimaiga, however, needs cool, moist conditions, whereas climate change is bringing hot, dry conditions to the range of the insect. Here we use an empirically verified eco-climate model to project that climate change will sharply reduce E. maimaiga infection rates, thereby increasing spongy moth defoliation. Recent rebounds in defoliation are consistent with our projections. Our work demonstrates that the effects of climate change on species interactions can have important consequences for natural ecosystems. The authors constructed an eco-climate model to project climate change impacts on populations of the spongy moth (Lymantria dispar) and its pathogen Entomophaga maimaiga.

Second, through a reflective process involving all co-authors, we identified: (1) main constraints and opportunities for adaptation, and (2) if adaptation was incremental or transformational. Questionnaire data show that farmers in all sites perceive multiple impacts, and that they mostly respond by intensifying farming practices and using off-farm labour. We established that, while several constraints were shared across sites, others were context specific; and that adaptation was mostly incremental, but that certain attributes (for example, social capital) made three sites in East Africa slightly more transformational. Climate change is impacting mountain regions and the agricultural livelihood of residents, and will continue to do so.

However, the intricate interplay among LSF, spring phenology and photosynthetic carbon uptake remains poorly understood. Using 286,000 ground phenological records involving 870 tree species and remote-sensing data across the Northern Hemisphere, we show that LSF occurrence in a given year reduces photosynthetic productivity by 13.6%, resulting in a delay in spring phenology by ~7.0 days in the subsequent year. Our experimental evidence, along with simulations using modified process-based phenology models, further supports this finding. This frost-induced delay in spring phenology subsequently leads to a decrease in photosynthetic productivity during the next year following an LSF event. Therefore, it is essential to integrate this frost-induced delay in spring phenology into current Earth system models to ensure accurate predictions of the impacts of climate extremes on terrestrial carbon cycling under future climate change. The authors use ground-based records and remote-sensing data to show that late spring frost delays the timing of spring leaf-out in the subsequent year by reducing photosynthetic productivity. Integrating late spring frost into models can increase the accuracy of predictions of spring timings and carbon cycling.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 2","pages":"201-209"},"PeriodicalIF":29.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929665","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}

High-resolution climate models improve understanding of MHWs under global warming, but such events in the future Arctic are currently overlooked. In a high-resolution climate model, we find Arctic MHWs intensify on orders of magnitude during the warming twenty-first century, following sea ice retreat. However, with little sea ice coverage, strong interannual variability emerges, which could surpass the amplitude of former intensification. Furthermore, the enhancement of MHWs correlates with an order of magnitude increase in the rate of change in the temperature anomaly. Additionally, MHWs are found to be accompanied by stratification enhancement, which could surpass interannual variability of future stratification. Such extreme temperature fluctuations combined with stratification enhancement suggest major challenges for Arctic ecosystems, and may negatively impact food webs through direct physiological temperature effects, as well as indirectly through nutrient supply and taxonomic shifts. Arctic warming will decrease sea ice cover and increase the possibility of intensified marine heatwaves. Using a high-resolution model, the authors show that this intensification, combined with strengthened short-term temperature variability and enhanced stratification, could threaten the ecosystem.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 2","pages":"162-170"},"PeriodicalIF":29.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-024-02224-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929668","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}

With climate change, the rapid change in frequency and intensity of tropical cyclones may alter the composition of the ecosystems themselves potentially degrading the services they provide. Here we classify global ecoregions into dependent, resilient and vulnerable and show that a combined 9.4% of the surface of all terrestrial ecosystems is susceptible to transformation due to cyclone pattern changes between 1980–2017 and 2015–2050 under climate scenario SSP5-8.5 using the STORM model. Even for the most resilient ecosystems already experiencing winds >60 m s−1 regularly, the average interval between two storms is projected to decrease from 19 to 12 years which is potentially close to their recovery time. Our study advocates for a shift in the consideration of the tropical cyclone impact from immediate damage to effects on long-term natural recovery cycles. The authors model the impact of changing tropical cyclone activity on coastal ecosystems. Under SSP5-8.5, by 2050 nearly 10% of terrestrial ecosystems will be at risk from changing tropical cyclone frequency, threatening the recovery potential of even the most resilient ecoregions.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"15 1","pages":"92-100"},"PeriodicalIF":29.6,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-024-02194-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917117","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}
