Au moment où le continent fait face à des températures extrêmes, la Commission européenne a entrepris d’affaiblir plusieurs politiques écologiques majeures, sous la pression conjointe des Etats membres, de la droite et de l’extrême droite.

Een rechtvaardig grondstoffenbeleid is een voorwaarde voor duurzame vrede in Congo, weet Wies Willems die als expert natuurlijke rijkdommen werkt voor Broederlijk Delen. Ook de EU moet daarin haar verantwoordelijkheid opnemen, benadrukt hij.

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

On 21 April 2019, I was on Waterloo Bridge in London with my younger siblings. Around us were planters full of flowers where there were once cars, and people singing. This was the spring iteration of Extinction Rebellion, when four bridges in London were held by protesters. My siblings, then 14, had been going out on school strike inspired by Greta Thunberg, and wanted to see her speak.

Young people will be exposed to a number of heatwaves that no one would have experienced in pre-industrial times. Young people will be exposed to a number of heatwaves that no one would have experienced in pre-industrial times.

Have you ever thought about what would happen if all life in the ocean disappeared? A recent study explores this extreme scenario to understand how ocean biology shapes the past, present, and future climate. The ocean plays a critical role in regulating Earth's climate. It is a massive carbon store that absorbs about 25% of human-caused emissions and thus helps maintain a relatively low CO2 level in the atmosphere. But what would happen if all marine life—from the tiniest plankton to the largest whales—disappeared? A recent study delves into this extreme scenario to uncover the crucial role that ocean biology plays in mitigating climate change.

Outdoor field trials which could include injecting aerosols into the atmosphere, or brightening clouds to reflect sunshine, are being considered by scientists as a way to prevent runaway climate change. Aria, the Government’s advanced research and invention funding agency, has set aside £50 million for projects, which will be announced in the coming weeks.

Sous l’impulsion du duo Donald Trump-Elon Musk, l’exécutif américain a annoncé de nombreux licenciements dans l’administration. Difficiles à suivre et à compter, ces coupes dans les effectifs révèlent les cibles prioritaires de la Maison Blanche.

Engagé de longue date dans le soutien aux parents d’enfants neuroatypiques, le président des Etats-Unis défend des positions archaïques sur l’autisme. Depuis vingt ans, sa vision est influencée par la fille d’un couple d’amis, passée de l’errance médicale à un combat antivax. C’est l’histoire d’une lubie trumpiste pas comme les autres. En mars, le nouveau ministre de la santé des Etats-Unis, le lobbyiste Robert F. Kennedy Jr, a confié aux Centres de contrôle des maladies (CDC), la principale agence de santé du pays, la mission d’étudier le lien fantasmatique entre autisme et vaccination.

Morgan Stanley, JPMorgan and an international banking group have quietly concluded that climate change will likely exceed the Paris Agreement’s 2 degree goal.Top Wall Street institutions are preparing for a severe future of global warming that blows past the temperature limits agreed to by more than 190 nations a decade ago, industry documents show.

Le président américain a souvent exploité le conflit à des fins politiques. Mais il s’était toujours tenu à une position neutre, sans nier une « attaque » russe.

... An “acid” test of our interpretation will be provided by the 2025 global temperature: unlike the 1997-98 and 2015-16 El Ninos, which were followed by global cooling of more than 0.3°C and 0.2°C, respectively, we expect global temperature in 2025 to remain near or above the 1.5°C level. Indeed, the 2025 might even set a new record despite the present weak La Nina. There are two independent reasons. First, the “new” climate forcing due to reduction of sulfate aerosols over the ocean remains in place, and, second, high climate sensitivity (~4.5°C for doubled CO2) implies that the warming from recently added forcings is still growing significantly.

An international group of scientists, led by King's College London, has revealed how continued global warming will lead to more parts of the planet becoming too hot for the human body over the coming decades. the amount of landmass on our planet that would be too hot for even healthy young humans (18 to 60-year-olds) to keep a safe core body temperature will approximately triple (to 6%)—an area almost the size of the US—if global warming reaches 2°C above the preindustrial average.

The directive follows President Trump's orders reversing climate policies.

C’est un mot en 9 lettres qui fend le ciel bleu que la météo hivernale (certes froide) nous offre depuis quelques jours : "exécrable". On ne parle évidemment pas de la lumière, carburant essentiel de nos réserves en vitamine D, mais de ce qui ne se voit pas au premier coup d’œil : la qualité de l’air. Or, elle est "exécrable" donc dans les principales villes du pays.

The abrupt loss of many species from a system is generally attributed to a breakdown in ecological functioning. As species are sequentially knocked out, the whole community becomes unstable, and it all comes crashing down. Another mechanism that may be at play. My colleagues and I argue that despite the fact life on Earth displays such great variety, many species that live together appear to share remarkably similar thermal limits. That is to say, individuals of different species can tolerate temperatures up to similar points.

Thirteen of the ports with the highest supertanker traffic will be seriously damaged by just 1 metre of sea level rise, the analysis found. The researchers said two low-lying ports in Saudi Arabia – Ras Tanura and Yanbu – were particularly vulnerable. Both are operated by Aramco, the Saudi state oil firm, and 98% of the country’s oil exports leave via these ports.

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).

Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluster of Excellence for climate research CLICCS. Since 2007, conditions in the Arctic have shifted, as confirmed by data recently published in the journal Communications Earth & Environment. Between 2007 and 2021, the marginal zones of the Arctic Ocean experienced 11 marine heat waves, producing an average temperature rise of 2.2 degrees Celsius above seasonal norm and lasting an average of 37 days. Since 2015, there have been Arctic marine heat waves every year.

With the help of the contingency concept, the article explores the reasons behind these surprises by introducing a new category of threats that complements the ones in the existing literature on surprise. It adds the concept of ‘known—corporally unknown’ threats to the list of known-unknowns, unknown-unknowns as a way to emsphasize the difference between abstract knowledge of ‘facts and figures’ (of e.g., global warming) and the acquiring of knowledge through personal, bodily experience (tangere) (of flooding and draughts).

As an average citizen of the United States, one with no particular power over our political trajectory beyond my ability to vote and encourage others to vote, I have very little say in how our descent into a hotter, resource-depleted world will play out. This contrasts with how much I worry about that impending descent, its impact on my children and grandchildren, and its deep implications for the future of humanity writ large.

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

But the decline in oil, gas and coal will not be steep enough to limit global warming to 1.5C

More than 1 billion cows around the world will experience heat stress by the end of the century if carbon emissions are high and environmental protection is low, according to new research published in Environmental Research Letters. This would mean cattle farming would face potentially lethal heat stress in much of the world, including Central America, tropical South America, Equatorial Africa, and South and Southeast Asia.

Population ecologist William Rees, with the University of British Columbia's School of Community and Regional Planning, is reminding denizens of Earth that the planet can only support so many people. In his paper published in the journal World, he points out that many models have been developed over the years that show that only a certain number of animals (such as rats) can live in a given environment—they all show that at some point, a population correction occurs.

C'est ce qu'affirme un éminent économiste écologique. C'est une sombre prédiction qu'a faite le professeur William Rees, de l'Université de Colombie-Britannique. Si son nom n'est pas très connu en France, un concept qu'il a développé l'est bien davantage: l'empreinte écologique....

In de Verenigde Staten hebben zestien jongeren gelijk gekregen in een rechtszaak tegen de staat Montana. De jongeren vochten een regel aan die verbood om de impact van wetten op het klimaat te bestuderen. De staat moet voortaan rekening houden met de CO₂-uitstoot en de gevolgen ervan op droogte, bosbranden en andere klimaatrisico’s. Het was de eerste Amerikaanse klimaatzaak die het tot in de rechtbank schopte.

Homo sapiens has evolved to reproduce exponentially, expand geographically, and consume all available resources. For most of humanity’s evolutionary history, such expansionist tendencies have been countered by negative feedback. However, the scientific revolution and the use of fossil fuels reduced many forms of negative feedback, enabling us to realize our full potential for exponential growth. This natural capacity is being reinforced by growth-oriented neoliberal economics—nurture complements nature. Problem: the human enterprise is a ‘dissipative structure’ and sub-system of the ecosphere—it can grow and maintain itself only by consuming and dissipating available energy and resources extracted from its host system, the ecosphere, and discharging waste back into its host. The population increase from one to eight billion, and >100-fold expansion of real GWP in just two centuries on a finite planet, has thus propelled modern techno-industrial society into a state of advanced overshoot. We are consuming and

Par John Dearing, Gregory Cooper et Simon Willcock via The Conversation, traduction A l’encontre. Selon une étude parue dans la revue Nature Sustainability, sous la pression des activités humaines, nous pourrions subir des effondrements des écosystèmes avec des points de basculements jusqu’à 80% plus tôt que ce que les modèles envisagent.

Partout dans le monde, les forêts tropicales humides se transforment en savane ou en terres agricoles, la savane s’assèche et se transforme en désert, et la toundra glacée fond. En effet, des études scientifiques ont désormais enregistré des « changements de régime » de ce type dans plus de 20 types d’écosystèmes différents, où des points de basculement ont été franchis. Dans le monde entier, plus de 20 % des écosystèmes risquent de changer de régime ou de s’effondrer. Ces effondrements pourraient se produire plus tôt qu’on ne le pense. L’homme soumet déjà les écosystèmes à de nombreuses pressions, que nous appelons « stress ». Si l’on ajoute à ces pressions une augmentation des phénomènes météorologiques extrêmes liés au climat, la date à laquelle ces points de basculement sont franchis pourrait être avancée de 80 %.

Updated, more accurate data gives a new look at the effects of sea level rise.

Around the world, rainforests are becoming savanna or farmland, savanna is drying out and turning into desert, and icy tundra is thawing. Indeed, scientific studies have now recorded "regime shifts" like these in more than 20 different types of ecosystem where tipping points have been passed. Around the world, more than 20% of ecosystems are in danger of shifting or collapsing into something different.

Alors que les événements climatiques extrêmes se multiplient, les discours niant le consensus scientifique sur le dérèglement du climat progressent. Derrière une façade pseudo-experte, leurs incohérences trahissent une profonde malhonnêteté intellectuelle.

A major concern for the world’s ecosystems is the possibility of collapse, where landscapes and the societies they support change abruptly. Accelerating stress levels, increasing frequencies of extreme events and strengthening intersystem connections suggest that conventional modelling approaches based on incremental changes in a single stress may provide poor estimates of the impact of climate and human activities on ecosystems. We conduct xperiments on four models that simulate abrupt changes in the Chilika lagoon fshery, the Easter Island community, forest dieback and lake water quality—representing ecosystems with a range of anthropogenic interactions. Collapses occur sooner under increasing levels of primary stress but additional stresses and/or the inclusion of noise in all four models bring the collapses substantially closer to today by ~38–81%. We discuss the implications for further research and the need for humanity to be vigilant for signs that ecosystems are degrading even more rapidly than previo
