Summary: Hydropower is a crucial renewable energy source for the decarbonization of the power grid, but assessing its availability in a changing climate is challenging due to uncertainties in modeling key dynamics. This study evaluates the impact of climate and reservoir-hydropower models' uncertainties on monthly hydropower projections, utilizing a multi-model assessment approach. Results show that both climate and hydropower models contribute to uncertainties, with climate models being more influential at the annual scale and hydropower models playing a significant role in seasonal variability, particularly in the western US where reservoir storage is significant.

Summary: The study indicates that under the reference scenario for 2040 aligned with EU climate and energy strategies, there is an increase in generation from fossil fuels, particularly from combined cycle gas turbine plants, to compensate for the reduction in hydro generation due to hydroclimatic scenarios. This reduction, along with shutdown events of thermal plants in the IP region caused by high water temperatures, results in load cuts that undermine the reliability of the electricity system. Furthermore, the increased use of fossil fuels leads to higher generation costs and carbon intensity, jeopardizing emissions reduction targets and slowing down the decarbonization process.

Summary: Economic inequality and climate change are crucial issues, with the Global North and wealthier classes being the main drivers of global carbon emissions. Reducing income inequality can help reduce carbon footprint inequalities, but it may not significantly decrease total emissions. Recomposing consumption by reducing inequalities in household expenditure and reallocating the reductions to public services can lead to significant reductions in carbon footprint on both individual country and global levels.

Summary: The role of soil organic carbon (SOC) sequestration as a 'win-win' solution to both climate change and food insecurity is critically examined in this article. The inclusion of SOC saturation in estimations significantly reduces the potential contribution of SOC sequestration to climate change mitigation, and the observed yield effects of increasing SOC are inconsistent. The article argues for a shift towards soil-smart agriculture that takes into account specific local conditions and quantifies multiple soil functions for land sustainability and food security.

Summary: The cost-benefit analysis of climate change heavily relies on the choice of damage function, which is difficult to obtain credible information for. Comparison of multiple models reveals that the optimum temperature for climate change may be lower than previously estimated. Economic analyses of global climate change have been criticized for their inadequate representation of the damages caused. The study developed and applied aggregate damage functions in three different Integrated Assessment Models (IAMs) with varying levels of complexity, including a wide but incomplete range of climate change impacts. The results show that global damages, based on medium estimates for damage functions, are projected to be approximately 10% to 12% of the GDP by 2100 under a baseline scenario with 3 degrees C temperature increase, and about 2% under a well-below 2 degrees C scenario. These damages exceed previous estimates from benefit-cost studies and indicate that optimal temperatures might be below 2 degrees C when considering damages and discount rates. Furthermore, the benefit-cost ratios range from 1.5 to 3.9, even without factoring in unaccounted damages such as biodiversity losses, health impacts, and tipping points.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
