The study uses a transformative worldview to give voice to an economically marginalized group of tenant farmers vulnerable to climate changes due to their calamity prone geographical location. Drawing on anthropogenic global warming (AGW) theory lens, we examine the impact of manmade actions on climate change in District "Swat" and "Malakand" of Khyber Pakhtunkhwa (KPK) province, Pakistan using a sequential mixed methods research design. Through this research design, the results of quantitative survey were complemented with a qualitative analysis of in-depth interviews. In first phase, we conducted a survey of 200 tenant farmers, followed by second wave of data collection involving 12 open-ended in-depth interviews (IDIs). The both qualitative and quantitative results suggest that farmers in both districts are affected by climate change although their crop yield had progressively increased signaling better coping and survival skills than other parts of country. Majority of respondents believed that climate change is something beyond their control in disagreement with AGW theory. Major economic losses were specifically, due to sudden alterations in weather patterns, such as floods, and hailstorms that reduce productivity as well as results in food waste with no avenues available to reclaim the energy laden in organic food waste. Besides, a productivity loss was attributed to outdated farming, lack of awareness regarding sharecropping and crop loan insurance practices. The study concludes that farmers are most vulnerable to climate change in socioeconomic terms as such changes impact their income sources; This inwardly compels cash strapped tenant farmers to delve in practice of informal credit with substantive risks attached which further deteriorates their livelihoods. The study offers understanding of how low-literate and economically marginalized indigenous tenant farmers cope to climate change and offers policy recommendations to advocate for the rights to earn sustainable livelihoods in the face of grand climate challenge.

Previous health impact assessments of temperature-related mortality in Europe indicated that the mortality burden attributable to cold is much larger than for heat. Questions remain as to whether climate change can result in a net decrease in temperature-related mortality. In this study, we estimated how climate change could affect future heat-related and cold-related mortality in 854 European urban areas, under several climate, demographic and adaptation scenarios.

Assessing the impact of climate change on water-related ecosystem services (ES) in Protected Areas (PAs) is essential for developing soil and water conservation strategies that promote sustainability and restore ES. However, the application of ES research in Protected Area (PA) management remains ambiguous and has notable shortcomings. This study primarily aimed to assess the SDR-InVEST (Sediment Delivery Ratio-Integrated Valuation of Ecosystem Services and Tradeoffs) model for estimating ES, including soil loss, sediment export, and sediment retention, under various climate change scenarios from 1997 to 2100 in the data-scarce region of the Bagh-e-Shadi Forest PA.

Tipping elements on Earth are components that undergo rapid and irreversible changes when climate change reaches a tipping point. They are highly sensitive to climate variations and serve as early warning signs of global change. Human activities, including global climate pledges, significantly influence the climate and the state of tipping elements.

Climate change-related risk mitigation is typically addressed using cost-benefit analysis that evaluates mitigation strategies against a wide range of simulated scenarios and identifies a static policy to be implemented, without considering future observations. Due to the substantial uncertainties inherent in climate projections, this identified policy will likely be sub-optimal with respect to the actual climate trajectory that evolves in time. In this work, we thus formulate climate risk management as a dynamic decision-making problem based on Markov Decision Processes (MDPs) and Partially Observable MDPs (POMDPs), taking real-time data into account for evaluating the evolving conditions and related model uncertainties, in order to select the best possible life-cycle actions in time, with global optimality guarantees for the formulated optimization problem.

Coal tar-related products as a source of polycyclic aromatic compounds (PACs) are particularly concerning due to high PAC concentrations and inadequate source management. Benzo[b]carbazole, a benzocarbazole isomer exclusively found in coal tar-derived products, acts as an ideal marker to distinguish coal tar sources from others, enabling more robust quantification of coal tar contributions to PACs. To evaluate the historical and recent contributions of coal tar-related sources to the levels of PACs in Lake Ontario and associated ecological risk, we analyzed 31 PACs and 3 BCBz isomers in surface sediments and a sediment core.
