A recent UK national security assessment on biodiversity and ecosystem collapse made headlines, not for its dire warnings, but for its omissions. It's part of a larger trend of governments keeping climate security reports from the public.
I know it’s almost impossible to turn your eyes away from the Trump show, but that’s the point. His antics, ever-grosser and more preposterous, are designed to keep him in our minds, to crowd out other issues. His insatiable craving for attention is a global-threat multiplier. You can’t help wondering whether there’s anything he wouldn’t do to dominate the headlines.

décembre 2025

Neonicotinoid insecticides are a major driver of pollinator decline. Due to their persistence and mobility in soil, they can contaminate non-target vegetation through runoff or dust, reaching pollinator resources. However, predicting soil contamination is challenging, especially where pesticide use data is lacking. This study assessed the potential of using proxies such as cropping history and landscape structure to predict neonicotinoid content in soils. We analyzed seven neonicotinoids in 86 sites in agricultural landscapes of Belgium.

A climate-focused report out of Europe throws serious shade at plug-in hybrid electric (PHEV) cars, pointing out that they emit nearly as much carbon dioxide emissions as combustion engine-powered vehicles. In fact, it highlights how real-world emissions from supposedly greener PHEVs has increased over the years above officially recorded figures to nearly five times. Yikes! The findings come from the European Federation for Transport and Environment (T&E), a clutch of non-government organizations focused on sustainable transport policy across the continent. The report has been published ahead of a review of automotive CO2 emission standards, which would see Europe continue to sell plug-in hybrid electric vehicles beyond 2035, when they're set to be phased out in order to meet EU climate targets.

This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC's Working Group III. This bias stems from structural features of the scientific field that prioritizes innovation, leading to the overrepresentation of technological solutions in climate research. Funding mechanisms further reinforce this tendency by incentivizing collaboration with industrial R&D, creating a self-reinforcing loop in which scientific authority and industrial interests converge. The IPCC's institutional positioning—as a policy-relevant yet politically cautious body—amplifies this dynamic by favoring allegedly “cost-effective” technological pathways that lack practical feasibility.

Why is the Trump Administration trying to kill a small space science institute in New York City? Explanation begins with Galileo’s method of scientific inquiry and ends with the role of special interest money in the United States government. Galileo improved the telescope, allowing clearer observations of the planets and the Sun. Galileo differed from his peers, as he was unafraid to challenge authority. He claimed that the world should be understood based on observations, and he spoke directly to the public. He obtained philanthropic support for his observations and openly described the conclusion that Earth was not the center of the solar system – Earth revolved around the Sun.

Clouds play an important role in how much the Earth warms when greenhouse gases like carbon dioxide increase. However, scientists have struggled to determine whether low-level clouds in the tropics slow down or speed up global warming, creating uncertainty in climate predictions. A new study published in Nature adds to the growing evidence that cloud feedback is very likely to amplify warming in the climate system, rather than reduce it.

ibrio are bacteria that cause an estimated 80,000 illnesses each year in the United States. About a dozen species of Vibrio are pathogenic to humans. V. parahaemolyticus causes the most infections in the United States, accounting for about 40% of reported cases of vibriosis, followed by V. alginolyticus, which accounts for about 20%. Most people with Vibrio infection have diarrhea. Some people might also have stomach cramping, nausea, vomiting, fever, and chills. One species, V. vulnificus, is known to cause life-threatening infections. About 150–200 V. vulnificus infections are reported to CDC each year and about one in five people with this infection die—sometimes within 1–2 days of becoming ill.

Vaccination, despite being recognized as one of the most effective primary public health measures, is viewed as unsafe and unnecessary by an increasing number of individuals. Anxiety about vaccines and vaccination programs leading to vaccine hesitancy results from a complex mix of social and political influences, cultural and religious beliefs, the availability of and ability to interpret health and scientific information, and personal and population experiences of health systems and government policies. Vaccine hesitancy is becoming a serious threat to vaccination programs, and was identified as one of the World Health Organization’s top ten global health threats in 2019. The negative impact of anti-vaccination movements is frequently cited as one of the major reasons for rising vaccine hesitancy amongst the general public world-wide. This review discusses the various issues surrounding vaccine hesitancy and the anti-vaccine movement, starting with the definitions of vaccine hesitancy and the anti-vaccine mo

Water vapor is Earth’s most abundant greenhouse gas. It’s responsible for about half of Earth’s greenhouse effect — the process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. Greenhouse gases keep our planet livable. Without them, Earth’s surface temperature would be about 59 degrees Fahrenheit (33 degrees Celsius) colder. Water vapor is also a key part of Earth’s water cycle: the path that all water follows as it moves around Earth’s atmosphere, land, and ocean as liquid water, solid ice, and gaseous water vapor.

SACRAMENTO -- Data from the California Energy Commission (CEC) shows that 59 percent of the state’s electricity came from renewable and zero-carbon sources in 2020. The CEC estimates that in 2020, 34.5 percent of the state’s retail electricity sales were served by Renewables Portfolio Standard (RPS)-eligible sources such as solar and wind. When sources of zero-carbon energy such as large hydroelectric generation and nuclear are included, 59 percent of the state’s retail electricity sales came from non-fossil fuel sources in 2020. In 2019, over 60 percent of the state’s electricity came from renewable and zero-carbon sources. The decrease in 2020 is due to decline in hydroelectric generation caused by severe drought, as well as pandemic-related delays to new renewable energy projects.

Ultrafine particles (UFPs) are aerosols with an aerodynamic diameter of 0.1 µm (100 nm) or less. There is a growing concern in the public health community about the contribution of UFPs to human health. Despite their modest mass and size, they dominate in terms of the number of particles in the ambient air. A particular concern about UFPs is their ability to reach the most distal lung regions (alveoli) and circumvent primary airway defenses. Moreover, UFPs have a high surface area and a capacity to adsorb a substantial amount of toxic organic compounds. Harmful systemic health effects of PM10 or PM2.5 are often attributable to the UFP fraction. In this review, we examine the physicochemical characteristics of UFPs to enable a better understanding of the effects of these particles on human health. The characteristics of UFPs from diesel combustion will be discussed in the greatest detail because road vehicles are the primary source of UFP emissions in urban pollution hotspots. Finally, we will elaborate on the
