The Phanerozoic Eon has witnessed considerable changes in the climate system as well as abundant animals and plant life. Therefore, the evolution of the climate system in this Eon is worthy of extensive research. Only by studying climate changes in the past can we understand the driving mechanisms for climate changes in the future and make reliable climate projections. Apart from observational paleoclimate proxy datasets, climate simulations provide an alternative approach to investigate past climate conditions of the Earth, especially for long time span in the deep past. Here we perform 55 snapshot simulations for the past 540 million years, with a 10-million-year interval, using the Community Earth System Model version 1.2.2 (CESM1.2.2). The climate simulation dataset includes global distributions of monthly surface temperatures and precipitation, with a 1° horizontal resolution of 0.9° × 1.25° in latitude and longitude. This open access climate dataset is useful for multidisciplinary research, such as paleoclimate, geology, geochemistry, and paleontology.

China's recent environmental turn in urban development has been marked by a rush of urban green projects. Many city governments have lately focused on green infrastructure of a specific kind -the greenway. This article provides a preliminary assessment of the contributions of greenways to a new, environmentally benign form of urbanisation advocated by the central government. Through a case study of the city of Maanshan, it reveals that Chinese greenways are not just a sustainability fix for the economy's sake, as many urban green projects in China tend to be conceived. Although the greenways are far from being effective in stimulating tourism, they can promote urban liveability beyond the symbolic and lend material support to active travel. These findings endorse an analytical approach that gives equal emphasis to both the physical and political nature of emerging green infrastructure initiatives to more fully appreciate the logics and functions in their ongoing popularity.

Purpose This paper aims to explore the effects of leadership style and trust in leadership on employees’ affective commitment under the epidemic situation. Design/methodology/approach A total of 580 valid questionnaires were collected online targeting the hospitality and tourism employees working from home during the particular period of the COVID-19 Coronavirus crisis. Structural equation modeling was used to analyze the data with AMOS software. Findings The findings indicated that perceived transformational leadership was a positive predictor of trust in leadership and affective commitment. In addition to the positive contribution to commitment, trust in leadership also mediated the relationship between transformational leadership and organizational commitment. Originality/value The current study contributes to the literature on leadership and organizational commitment. The results of this study may provide a valuable guide to organizations, leaders and young employees.
