- Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1-km2 resolution for 0–5 and 5–15 cm soil depth. These maps were created by calculating the difference (i.e. offset) between in situ soil temperature measurements, based on time series from over 1200 1-km2 pixels (summarized from 8519 unique temperature sensors) across all the world's major terrestrial biomes, and coarse-grained air temperature estimates from ERA5-Land (an atmospheric reanalysis by the European Centre for Medium-Range Weather Forecasts). We show that mean annual soil temperature differs markedly from the corresponding gridded air temperature, by up to 10°C (mean = 3.0 ± 2.1°C), with substantial variation across biomes and seasons. Over the year, soils in cold and/or dry biomes are substantially warmer (+3.6 ± 2.3°C) than gridded air temperature, whereas soils in warm and humid environments are on average slightly cooler (−0.7 ± 2.3°C). The observed substantial and biome-specific offsets emphasize that the projected impacts of climate and climate change on near-surface biodiversity and ecosystem functioning are inaccurately assessed when air rather than soil temperature is used, especially in cold environments. The global soil-related bioclimatic variables provided here are an important step forward for any application in ecology and related disciplines. Nevertheless, we highlight the need to fill remaining geographic gaps by collecting more in situ measurements of microclimate conditions to further enhance the spatiotemporal resolution of global soil temperature products for ecological applications.

Journal article (peer-reviewed)abstract
- Nations which are part of the United Nations are required to institute appropriate measures to fulfil the vision of the Sustainable Development Goals (SDGs). However, for this to be possible, all stakeholders including the general public need to be fully aware of the SDGs. This research examined the level of public awareness about the SDGs among Ghanaians based on the views of 431 respondents. Means, standard deviation, Mann–Whitney U test, Kruskal Wallis and Pearson Product-Moment Correlations were used for data analysis. The study found that awareness level on SDG 1 (ending poverty), SDG 2 (zero hunger, food security, nutrition and sustainable agriculture), SDG 3 (health and well-being), SDG 5 (gender equality), and SDG 6 (clean water and sanitation) was high among Ghanaians. However, awareness level on SDG 9 (industry, innovation and infrastructure), SDG 14 (conservation of life below water), and SDG 16 (peace, justice and strong institutions) was very low among Ghanaians. No significant difference manifested in the level of awareness among male and female Ghanaians. There were statistically significant differences in educational levels of respondents and their overall level of awareness of the SDGs. Also, there was a low, negative correlation between overall level of awareness and the effectiveness of the communication strategies used in creating awareness about the SDGs. Government should re-examine its communication strategies on the SDGs and put in place a more effective communication policy framework which involves grassroots populations and local communities.
