‘Catastrophic’ global decline due to dams, mining, diverting water and pollution threatens humans and ecosystems, study warns

2023

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
After hottest day ever, researchers say global heating may mean future of crop failures on land and ‘silent dying’ in the oceans
More than 40% of land vertebrates will be threatened by extreme heat by the end of the century under a high emissions scenario, with freak temperatures once regarded as rare likely to become the norm, new research warns. Reptiles, birds, amphibians and mammals are being exposed to extreme heat events of increasing frequency, duration and intensity, as a result of human-driven global heating. This poses a substantial threat to the planet’s biodiversity, a new study warns. Under a high emissions scenario of 4.4C warming, 41% of land vertebrates will experience extreme thermal events by 2099, according to the paper, published in Nature.

Materials put into domestic compost are failing to disintegrate after six months – the only solution is to use less. Most plastics marketed as “home compostable” don’t actually work, with as much as 60% failing to disintegrate after six months, according to research.
Industry groups representing some of the world’s largest companies are “opposed to almost all major biodiversity-relevant policies” and are lobbying to block them, according to a new report. Researchers found that 89% of engagement by leading industry associations in Europe and the US is designed to delay, dilute and block progress on tackling the biodiversity crisis, which scientists say is as serious as the climate emergency.

Sustainable food systems are a cornerstone to cutting emissions but have been largely absent from the agenda in Glasgow. Farming is a complex issue on the journey to net zero, as it is both a source and sink for emissions. About 20% of global emissions come from agriculture and land use, and this rises to more than 25% for the food system as a whole, which includes processing, packaging and transport.
Le nombre de brevets internationaux consacrés à des technologies bas carbone a crû depuis une vingtaine d'années -Mais leur taux de croissance annuel moyen baisse depuis quelques années, et est même depuis 2017 quatre fois plus faible que sur la période 2000-2013
