    Comprehensive assessment of climate extremes in high-resolution CMIP6 projections for Ethiopia
    (2023) Rettie, Fasil M.; Gayler, Sebastian; Weber, Tobias K. D.; Tesfaye, Kindie; Streck, Thilo
    Climate extremes have more far-reaching and devastating effects than the mean climate shift, particularly on the most vulnerable societies. Ethiopia, with its low economic adaptive capacity, has been experiencing recurrent climate extremes for an extended period, leading to devastating impacts and acute food shortages affecting millions of people. In face of ongoing climate change, the frequency and intensity of climate extreme events are expected to increase further in the foreseeable future. This study provides an overview of projected changes in climate extremes indices based on downscaled high-resolution (i.e., 10 × 10 km2) daily climate data derived from global climate models (GCMs). The magnitude and spatial patterns of trends in the projected climate extreme indices were explored under a range of emission scenarios called Shared Socioeconomic Pathways (SSPs). The performance of the GCMs to reproduce the observed climate extreme trends in the base period (1983–2012) was evaluated, the changes in the climate projections (2020–2100) were assessed and the associated uncertainties were quantified. Overall, results show largely significant and spatially consistent trends in the projected temperature-derived extreme indices with acceptable model performance in the base period. The projected changes are dominated by the uncertainties in the GCMs at the beginning of the projection period while by the end of the century proportional uncertainties arise both from the GCMs and SSPs. The results for precipitation-related extreme indices are heterogeneous in terms of spatial distribution, magnitude, and statistical significance coverage. Unlike the temperature-related indices, the uncertainty from internal climate variability constitutes a considerable proportion of the total uncertainty in the projected trends. Our work provides a comprehensive insight into the projected changes in climate extremes at relatively high spatial resolution and the related sources of projection uncertainties.

    Cultural, social and psychological factors of the conservative consumer towards legal cannabis use: A review since 2013
    (2022) Siddiqui, Shahida Anusha; Singh, Prachi; Khan, Sipper; Fernando, Ito; Baklanov, Igor Spartakovich; Ambartsumov, Tigran Garrievich; Ibrahim, Salam A.
    Cannabis consumption has become the center of much debate globally. The positive public perception of the medicinal benefits of cannabis and the rise of recreational usage of cannabis necessitate dramatic changes in cannabis reform policy. As a consequence, there is an increase in cannabis legalization around the globe, although it is still facing many rejections. It is crucial to understand the factors affecting public acceptance of cannabis use to support the contextualization and success of cannabis legalization. This review aims to address consumer cultural, social and psychological factors regarding the legal use of cannabis. Based on this review, cultures influence the endorsement or rejection of cannabis use depending on political views, religious sentiments and affiliated subcultures (adult, youth and adolescent subcultures). Regarding the social factors, socioeconomic status, measured by income, education level and occupation, is a key determinant of cannabis use. The beliefs opposing cannabis legalization are due to the negative stigma surrounding cannabis use. Nevertheless, growing awareness about the pharmaceutical and therapeutic effects of cannabis has led to an increase in positive attitudes towards cannabis legalization. Thus, dissemination of cannabis use benefits reaffirmed by scientific evidence could be a strategic way to alleviate the public’s negative feedback on cannabis legalization.
