Effect of localisation and climate change on operation of data centres in Ukraine towards 2050

Data centres (DCs) are large electricity consumers, estimated to account for around 1% of worldwide electricity usage. They release excess heat (EH) during the operation, which can be recovered in district heating (DH) networks. DCs are expected to satisfy the rising demand for digital services.The electricity usage for cooling and available EH from the operation of DCs depends on the air temperature that changes with geographical location. The changes are not uniform and global warming pathways will influence them. Here lays the contribution of the present article. We use an existing thermodynamic model of a hyper-scale DC for different locations in Ukraine to analyse the electricity usage for cooling and EH availability for two climate scenarios (RCP2.6 and RCP 4.5) in 2010–2050.The results show that the electricity consumption for cooling and available EH can vary greatly within Ukraine. The electricity consumption for cooling is over two times higher in the hottest compared to the coldest location in the country, while the emitted EH is around 80% higher on average. The global climate pathway has a minor influence — the electricity use for cooling and EH availability are 4% higher in RCP4.5 than in RCP2.6. Finally, one hyper-scale DC of 150 MW could cover the demand for space heating and domestic hot water for roughly 100 thousand people. This assessment is an important input to consider when developing plans to rebuild Ukraine

Trust in scientists and their role in society across 67 countries

Scientific information is crucial for evidence-based decision-making. Public trust in science can help decision-makers act based on the best available evidence, especially during crises such as climate change or the COVID-19 pandemic. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists. Here we interrogated these concerns with a pre-registered 67-country survey of 71,417 respondents on all inhabited continents and find that in most countries, a majority of the public trust scientists and think that scientists should be more engaged in policymaking. We further show that there is a discrepancy between the public’s perceived and desired priorities of scientific research. Moreover, we find variations between and within countries, which we explain with individual-and country-level variables,including political orientation. While these results do not show widespread lack of trust in scientists, we cannot discount the concern that lack of trust in scientists by even a small minority may affect considerations of scientific evidence in policymaking. These findings have implications for scientists and policymakers seeking to maintain and increase trust in scientists
