CEOBS was launched in 2018 with the primary goal of increasing awareness and understanding of the environmental and derived humanitarian consequences of conflicts and military activities. In this, we seek to challenge the idea of the environment as a ‘silent victim of armed conflict’. Download our ‘About us‘ summary.

Wat hadden de wereldleiders weer beloofd in 2015 in de Franse hoofdstad? Ze zouden de opwarming van de aarde veroorzaakt door onze uitstoot van broeikasgassen beperken. Tot twee graden en liefst tot anderhalve graad. Daarvoor moesten ze doortastende én rechtvaardige maatregelen nemen. Ze hebben dat niet gedaan. Dat zien we op onze tv-schermen. De bosbranden, overstromingen en hittegolven worden talrijker en heviger. Met veel menselijke slachtoffers en schade voor alle leven op de planeet.

Extreem hoge temperaturen teisteren Noord-Amerika en ook China. In de VS en Canada is sprake van een heat dome of hittekoepel, terwijl Peking een van de warmste dagen van het jaar meemaakt. De overheden hebben waarschuwingen uitgestuurd om zoveel mogelijk binnen te blijven en grote inspanningen te vermijden.

In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets (published at https://doi.org/10.5281/zenodo.15639576; Smith et al., 2025a) to produce updated estimates for key indicators of the state of the climate system: net emissions of greenhouse gases and short-lived climate forcers, greenhouse gas concentrations, radiative forcing, the Earth's energy imbalance, surface temperature changes, warming attributed to human activities, the remaining carbon budget, and estimates of global temperature extremes. This year, we additionally include indicators for sea-level rise and land precipitation change. We follow methods as closely as possible to those used in the IPCC Sixth Assessment Report (AR6) Working Group One report.

Terwijl we nog eens een hittegolf beleven in de Lage Landen, leert het Wereld Meteorologisch Instituut ons dat die, samen met veel te lange droogtes en anderzijds veel te veel water op korte tijd, tot het nieuwe normaal behoren.

The human fingerprint on global warming was likely evident in Earth’s atmosphere far earlier than previously thought—even before the invention of modern cars, a new study says. Using a combination of scientific theory, modern observations and multiple, sophisticated computer models, researchers found a clear signal of human-caused climate change was likely discernible with high confidence as early as 1885, just before the advent of gas-powered cars but after the dawn of the industrial revolution.

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.

Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?
