« Je suppose qu’il est tentant, si le seul outil dont vous disposez est un marteau, de traiter tout comme s’il s’agissait d’un clou. » C’est ce qu’écrivait le célèbre psychologue Abraham Maslow en 1966. Si Maslow était encore parmi nous aujourd’hui, j’imagine qu’il approuverait le corolaire selon lequel si votre seul outil est la technologie, chaque problème semble avoir une solution technologique. Et c’est une caractérisation pertinente de la pensée centrée sur les « tech bro » qui prévaut aujourd’hui dans le discours public sur l’environnement.

We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth.

“I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.” Thus wrote the famous psychologist Abraham Maslow in 1966.

De regering-Trump gaat Amerikaanse klimaatrapporten uit het verleden herbekijken en "updaten". Dat heeft de minister van Energie, Chris Wright, gezegd in een gesprek met de Amerikaanse zender CNN. Wright, die uit de sector van fossiele brandstoffen komt, krijgt veel kritiek uit de wetenschappelijke wereld. Klimaatwetenschapper Michael Mann vergelijkt de praktijken in The Guardian zelfs met die van Jozef Stalin,

Injecting pollutants into the atmosphere to reflect the sun would be extremely dangerous, but the UK is funding field trials

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).

En 2012, deux auteurs d’extrême droite avaient dénigré les travaux du célèbre climatologue Michael E. Mann. Une victoire pour la science du climat, devenue la cible préférée du complotisme.

Michael Mann, de l’université de Pennsylvanie aux États-Unis, fait partie des climatologues les plus en vue depuis qu’il a publié, en 1999, le célèbre graphique en forme de crosse de hockey, qui montre comment les températures mondiales ont grimpé en flèche au cours du siècle dernier. Pour comprendre la situation difficile dans laquelle nous nous trouvons aujourd’hui, Michael Mann a remonté l’histoire du climat de la Terre afin d’avoir une vision plus claire de notre avenir potentiel. « Nous disposons d’une période de 4 milliards d’années dont nous pouvons tirer des enseignements », a-t-il déclaré dans une interview au Guardian.

Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more
