No collapswashing

Economic assumptions about risks of the climate crisis are no longer relevant, says the communications expert Genevieve Guenther

For more than three decades, Brazilian climate scientist Carlos Nobre has warned that deforestation of the Amazon could push this globally important ecosystem past the point of no return. Working first at Brazil’s National Institute for Space Research and more recently at the University of São Paulo, he is a global authority on tropical forests and how they could be restored.

The Kenyan marine ecologist David Obura is chair of a panel of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the world’s leading natural scientists. For many decades, his speciality has been corals, but he has warned that the next generation may not see their glory because so many reefs are now “flickering out across the world”.

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.

The world has been too optimistic about the risk to humanity and planet – but devastation can still be avoided, says Timothy Lenton

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend

Real world measurements of how much extra heat the Earth is trapping are well beyond most climate models. That’s a real problem.

Une étude édifiante montre comment la désinformation climatique entrave l’action en faveur du climat. Qui désinforme ? Dans quels buts ? Comment réduire les fausses informations ? Explications.

Alors que les soldes d’été, qui se déroulent du 25 juin au 22 juillet, viennent de débuter, la question du recyclage des déchets textiles reste lancinante. Ces derniers finissent le plus souvent incinérés, alors qu’ils pourraient être revalorisés de diverses façons : isolants thermiques et acoustiques, mousse pour l’automobile, rembourrage de matelas, pour faire de nouveaux vêtements…

A subreddit tracking apocalyptic news in a calm, logical way comforts users who believe the end The threat of nuclear war, genocide in Gaza, ChatGPT reducing human cognitive ability, another summer of record heat. Every day brings a torrent of unimaginable horror. It used to be weeks between disasters, now we’re lucky to get hours.

Alors qu’une large part de la France est placée en vigilance canicule ce mercredi 25 juin, se pose la question de l’influence du changement climatique sur le cycle de l’eau, entre modification du régime des pluies et augmentation de la fréquence des événements extrêmes (sécheresses et inondations). Qu’en est-il des eaux souterraines ? Ces dernières, logées dans les profondeurs du sous-sol, ne sont pas à l’abri de ces changements qui touchent en premier lieu l’atmosphère et la surface de la Terre.

Between 80% and 89% of the world’s people want their governments to do more about climate change. This fact is the central tenet of the 89% Project for climate journalism. Timed to coincide with Earth Day and Earth Week, the project launched in April, 2025, and will culminate in another week of focused stories in October, just before the next COP meeting in Brazil.

Pourquoi la guerre nucléaire, et non la crise climatique, est la plus grande menace qui pèse sur l’humanité, selon Mark Lynas Mark Lynas a passé des décennies à faire pression pour que l’on agisse sur les émissions de gaz à effet de serre, mais il affirme aujourd’hui que la guerre nucléaire est une menace encore plus grande.

Depuis 2007, les dirigeants chinois affirment mettre en place une « civilisation écologique ». Lorsque l’on regarde la décarbonation comme la réduction des gaz à effet de serre, alors que les États-Unis reculent, la Chine, elle avance… mais vers quelle écologie ?

Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global

Iran’s parliament approved a measure to close the vital global trade route, through which more than a fifth of the world’s oil supply passes through daily

Heat waves are getting more dangerous with climate change — and we may still be underestimating them

Climate misinformation campaigns have shifted tactics, a comprehensive new analysis shows.

New data from Nasa has revealed a dramatic rise in the intensity of weather events such as droughts and floods over the past five years.The steepness of the rise was not foreseen. The researchers say they are amazed and alarmed by the latest figures from the watchful eye of Nasa’s Grace satellite, which tracks environmental changes in the planet.

Il y a dix ans entrait en vigueur la loi relative à l'économie sociale et solidaire (ESS), dite loi Hamon, qui a défini le périmètre de cette économie solidaire, démocratique et à lucrativité limitée. A cette occasion, Novethic a rencontré celui qui fut l'instigateur de cette loi, Benoît Hamon, ancien ministre et désormais président d'ESS France, pour évoquer l'importance de ce secteur, face aux dérives du capitalisme contemporain.
