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.

Dozens of companies and academic groups are pitching the same theory: that sinking rocks, nutrients, crop waste or seaweed in the ocean could lock away climate-warming carbon dioxide for centuries or more. Nearly 50 field trials have taken place in the past four years, with startups raising hundreds of millions in early funds. But the field remains rife with debate over the consequences for the oceans if the strategies are deployed at large scale, and over the exact benefits for the climate. Critics say the efforts are moving too quickly and with too few guardrails.

Mechanisms behind a steep rise in temperature

The results of one election can’t stop the momentum of the energy transition. But they can do a lot of damage.

The election of Donald Trump as president for a second time and the Republican takeback of the U.S. Senate could undo many of the national climate policies that are most reducing planet-warming greenhouse gas emissions, according to climate solutions experts.When they list measures that are making the most difference, it lines up with policies Trump has said he’ll target. These rollbacks will come as more lives are being lost in heat waves, record amounts of climate pollution are accumulating in the atmosphere, the United States has been hit with what may be two of its most expensive hurricanes, and nations, which will meet in Baku, Azerbaijan next week for climate negotiations, have failed to take strong action to change these realities.

AMOC collapse would bring severe global climate repercussions, with Europe bearing the brunt of the consequences.

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

Alors que l’augmentation des températures en Afrique est légèrement supérieure à la moyenne mondiale, le continent africain doit supporter une charge de plus en plus lourde liée au changement climatique et des coûts disproportionnés pour l’adaptation essentielle au climat, a indiqué lundi, une agence des Nations Unies.

The world is currently seeing the fastest-spreading, largest-ever outbreak of H5N1, a highly contagious, deadly strain of avian influenza. Scientists say this virus now presents an existential threat to the world’s biodiversity, with the risk to humans rising as it continues to leap the species barrier, reaching new host species.
