However, young generations can also play a crucial role in climate research, to produce scientific knowledge to mitigate and adapt to the climate crisis. Unlike senior scholars, who often have established and fixed knowledge systems, young people could bring fresh and innovative ideas to climate research. Furthermore, involving youth ensures a sustainable approach to tackling climate issues, as they will be the ones most affected in the long term.While opportunities and programmes such as these aim to bolster their voice, ECRs are still constrained by a lack of funding support, limited access to grant opportunities, substandard laboratory facilities and equipment, and a lack of tenure security. Also, they are often perceived as inexperienced and face limited access to engage in the climate research field compared with senior researchers. For instance, only 6% of journal articles are reviewed by ECRs according to the report Peer Review in 2015: A Global View (https://go.nature.com/4ifeyZ7). It is also worth noting that ECRs often dedicate their unpaid ‘free time’ to enhance their future job prospects. As projects provide only temporary employment, the time invested is crucial for advancing their careers. Some ECRs may feel financial distress due to insufficient financial resources to support themselves. Their contributions and outputs should be fairly recognized and valued.","PeriodicalId":18974,"journal":{"name":"Nature Climate Change","volume":"48 1","pages":""},"PeriodicalIF":30.7,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874277","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}

Prairie","doi":"10.1002/lno.12767","DOIUrl":"https://doi.org/10.1002/lno.12767","url":null,"abstract":"Aquatic sediments represent a key component for understanding CH4 dynamics and emission to the atmosphere. Once produced in the sediments, CH4 is released either by diffusion at the sediment–water interface or by bubbling out to the atmosphere when total gas pressure in the sediment exceeds local ambient pressure due to high CH4 production. Although bubbling is one of the dominant CH4 emission pathways in lakes, direct measurements of this flux are hampered by its high spatiotemporal variability and methodological limitations. Here, we develop a conceptual approach to quantify CH4 production in lake sediments and particularly its release as bubbles based on simple measurements of bubble gas content and depth. Its main assumptions were empirically tested using > 200 long‐term bubble trap deployments collected from 4 temperate lakes. We then applied the developed methodology to a suite of 408 Canadian lakes to produce the first standardized large‐scale assessment of lakes CH4 ebullitive flux during summer. Our results show that lake sediments produced CH4 at a median rate of 3.3 mmol m−2 d−1 (ranged from 0.2 to 11.8 mmol m−2 d−1), releasing 33% via ebullition to the atmosphere. These rates are remarkably similar in magnitude to other regional estimates in the literature. Moreover, our approach revealed that catchment slope was an important determinant of both the lake‐wide ebullitive fluxes and the fraction of sediment CH4 production released as bubbles.","PeriodicalId":18143,"journal":{"name":"Limnology and Oceanography","volume":"10 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874280","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, we report evidence of how wood and bark were used in basket crafting and compare them with modern-day uses. On the northwestern coast of Türkiye, Zonguldak-Karadeniz Ereğli İnönü Cave has special conditions for the preservation of wood and other organic materials. In the Late Bronze Age Level III of the cave (1,436–1,123 Cal BC), baskets and evidence of basketry were found among water-filled puddles. These records are valuable for understanding how the environment surrounding archaeological sites was used by its settlers. Analyzes carried out to understand which types of trees in the environment are preferred for basket production highlighted European yew (Taxus baccata L.) and field maple (Acer campestre L.) species.

This sensitivity is not explicitly constrained in land models nor the model parameters important for this sensitivity identified. Here, we seek to understand parametric controls on runoff sensitivity to precipitation and temperature in a state-of-the-science land model, the Community Land Model version 5 (CLM5). Process-parameter interactions underlying these two climate sensitivities are investigated using the sophisticated variance-based sensitivity analysis. This analysis focuses on three snow-dominated basins in the Colorado River headwaters region, a prominent exemplar where land models display a wide disparity in runoff sensitivities. Runoff sensitivities are dominated by indirect or interaction effects between a few parameters of subsurface, snow, and plant processes. A focus on only one kind of parameters would therefore limit the ability to constrain the others. Surface runoff exhibits strong sensitivity to parameters of snow and subsurface processes. Constraining snow simulations would require explicit representation of the spatial variability across large elevation gradients. Subsurface runoff and soil evaporation exhibit very similar sensitivities. Model calibration against the subsurface runoff flux would therefore constrain soil evaporation. The push toward a mechanistic treatment of processes in CLM5 have dampened the sensitivity of parameters compared to earlier model versions. A focus on the sensitive parameters and processes identified here can help characterize and reduce uncertainty in water resource sensitivity to climate change.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"92 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874205","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}
