Summary: By quantifying terrestrial temperature data using a plant proxy approach, this study reveals that the climate near the palaeo-equator during the early Eocene was warmer than in mid- to high latitudes. The research also suggests that high rainfall levels near the palaeo-equator might have contributed to the resilience of tropical rainforests during the warm greenhouse world of the Early Eocene Climatic Optimum.

Summary: Quantifying changes in land surface height is crucial for understanding Earth processes, but uncertainties in elevation reconstructions largely stem from unconstrained thermal lapse rates. Using paleoclimate models can reduce and quantify uncertainties, improving predictive skill in estimating elevation changes.

Summary: We introduce a model of active responsive colloids in which the internal degree of freedom of a single colloidal particle is activated by coupling it to a different thermostat than for the translational degrees of freedom. By tuning the internal activity, we observe a rich and intriguing behavior in terms of emergent property distributions, colloidal pair structure, and diffusive translational dynamics. These findings suggest that particle dynamical polydispersity as well as the structure and dynamics of dense macromolecular suspensions can be vastly tuned by internal activity.

Summary: During the last deglaciation, atmospheric CO2 increased by about 75 ppm. The dominant source of this rise is likely the deep ocean, but a consensus on the entire 75 ppm remains elusive. The remainder is likely contributed by the terrestrial environment, specifically soil organic carbon (SOC) from the tropical montane Andes. This study finds that the thinning of the organic layer in the tropical montane Andes during the last deglaciation may have caused a leakage of CO2 into the atmosphere.

Summary: In this paper, an infinite chain of harmonic oscillators coupled with a Poisson thermostat is investigated. The energy density of the chain, described by the Wigner distribution, satisfies a transport equation outside the location of the thermostat. A boundary condition arises at this site, which explains the reflection-transmission-scattering of the wave energy influenced by the thermostat. The coefficients for these processes are obtained. Unlike the Langevin thermostat case studied in Komorowski et al. (Arch. Ration. Mech. Anal. 237, 497-543, 2020), the Poissonian thermostat scattering generates a continuous cloud of waves with frequencies different from the incident wave in the limit.

Summary: The study used fossil pollen and stable isotopes of rock hyrax middens from Wadi Sana, Yemen to investigate changes in ecosystem structure and function in southern Arabia from 6 ka to present. Results showed a landscape with abundant tropical trees during the mid-Holocene, with species like Terminalia and Boswellia sacra playing key roles in local hydrology and economy. Increased charcoal abundances suggest periodic wildfires, and a transition to desert conditions after 1 ka was indicated by increased sedge abundances.

Summary: As the transition towards electrification of building space heating accelerates, it becomes crucial to understand the impacts of these new electrical loads on the grid for future energy resource planning. This study provides a scalable, data-driven approach to estimate regional electrical demand using real-world data from thousands of homes. The findings highlight the unintended consequences of smart thermostat control algorithms, which can increase winter peak heating demand and hinder the integration of renewable energy and electric heating. The methodology provided in this study can be used as an open-source toolkit for analyzing other regions worldwide.

Summary: We developed a framework to investigate the drivers for and barriers against adopting integrated smart home technologies to encourage broader adoption of these technologies that can significantly reduce the environmental impact of residential buildings. The results showed that performance expectancy, effort expectancy, habit, and trust had significant effects on adoption intent. Privacy and transparency were found to be predictors of trust, and interaction adequacy and customizability had a strong effect on effort expectancy.
