This paper analyses General Social Survey (United States) data and provides evidence that the advent of Facebook and other social media platforms has widened the gap in scepticism towards science between low-educated Americans and their more highly educated counterparts. The same trend holds true when considering distrust in medicine, the press and television. Overall, the results suggest that education may serve as a protective factor against the influence of fake news, disinformation and misinformation. Additionally, a heterogeneity analysis shows that the increase in distrust is particularly pronounced among young people. Further analyses reveal that political affiliation plays a role in shaping attitudes towards science and that the likelihood of voting for the Republican Party has increased among low-educated individuals. A comprehensive set of robustness and placebo tests supports the reliability of these findings.
Some narratives in international development hold that ending poverty and achieving good lives for all will require every country to reach the levels of GDP per capita that currently characterise high-income countries. However, this would require increasing total global output and resource use several times over, dramatically exacerbating ecological breakdown. Furthermore, universal convergence along these lines is unlikely within the imperialist structure of the existing world economy. Here we demonstrate that this dilemma can be resolved with a different approach, rooted in recent needs-based analyses of poverty and development. Strategies for development should not pursue capitalist growth and increased aggregate production as such, but should rather increase the specific forms of production that are necessary to improve capabilities and meet human needs at a high standard, while ensuring universal access to key goods and services through public provisioning and decommodification. At the same time, in high
2024 was the hottest year on record [1], with global temperatures exceeding 1.5 °C above preindustrial climate conditions for the first time and records broken across large parts of Earth’s surface. Among the widespread impacts of exceptional heat, rising food prices are beginning to play a prominent role in public perception, now the second most frequently cited impact of climate change experienced globally, following only extreme heat itself [2]. Recent econometric analysis confirms that abnormally high temperatures directly cause higher food prices, as impacts on agricultural production [3] translate into supply shortages and food price inflation [4, 5]. These analyses track changes in overall price aggregates which are typically slow-moving, but specific food goods can also experience much stronger short-term price spikes in response to extreme heat.
Berkeley Earth, a California-based non-profit research organization, has been preparing independent analyses of global mean temperature changes since 2013. The following is our report on global mean temperature during 2021.
