Previous studies have primarily focused on greenhouse gas emissions from these fires, whereas the associated biomass burning aerosols (BBAs) have received less attention. Here we use satellite-constrained modelling to assess the radiative effect of aerosols from boreal fires on the climate in the Arctic region. We find a substantial increase in boreal BBA emissions associated with warming over the past two decades, causing pronounced positive radiative effects during Arctic summer mostly due to increased solar absorption. At a global warming level of 1 °C above current temperatures, boreal BBA emissions are projected to increase 6-fold, further warming the Arctic and potentially negating the benefits of ambitious anthropogenic black carbon mitigation. Given the high sensitivity of boreal and Arctic fires to climate change, our results underscore the increasingly relevant role of BBAs in Arctic climate. Boreal fires are expected to increase with warming, but how the aerosols emitted in these fires affect the climate is not well understood. Here the authors show that this increase in boreal fire aerosols results in a positive radiative forcing, leading to additional Arctic warming.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"14 12","pages":"1275-1281"},"PeriodicalIF":29.6,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142610325","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}

Most studies focus on abrupt changes in the mean state of the system, while transitions in climate variability are less well understood. Here, we use multimodel simulations to show that sea-ice loss in the Arctic can trigger a critical transition in internal variability that leads to the emergence of a new climate oscillation in the Arctic Ocean. The intensified air–sea interaction due to sea-ice melt causes an oscillatory behaviour of surface temperatures on a multidecadal timescale. Our results suggest that a new mode of internal variability will emerge in the Arctic Ocean when sea ice declines below a critical threshold. Abrupt transitions in the climate system are discussed mostly in terms of mean state changes. Here, the authors use simulations to show that a decline in Arctic sea ice can lead to a new multidecadal mode of surface temperatures in the Arctic Ocean.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"14 12","pages":"1268-1274"},"PeriodicalIF":29.6,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41558-024-02171-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142598347","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}

One promising method for achieving CO<sub>2</sub> removal at scale is ocean alkalinity enhancement (OAE), but there are challenges with incomplete air–sea CO<sub>2</sub> equilibration, which reduces the efficiency of carbon removal. Here, we present global maps of OAE efficiency, and assess the seasonal variation in efficiency. We find that the equilibration kinetics have two characteristic timescales: rapid surface equilibration followed by a slower second phase, which represents the re-emergence of excess alkalinity that was initially subducted. These kinetics vary considerably with latitude and the season of alkalinity release, which are critical factors for determining the placement of potential OAE deployments. Additionally, we quantify the spatial and temporal scales of the induced CO<sub>2</sub> uptake, which helps identify the requirements for modelling OAE in regional ocean models.</p>","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"69 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142596584","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}
