Brazil records 62% jump in area burned by forest fires: monitor

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.

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

La société SCA, premier propriétaire forestier privé en Europe, et le groupe Holmen, ont décidé de ne plus demander la certification durable, pour pouvoir produire plus. Les associations environnementales dénoncent des pratiques qui mettent à mal les vieilles forêts du pays.

La destruction de la couverture forestière a augmenté de 9,1 % entre août 2024 et mai 2025 par rapport à la même période l’année précédente.

Le Luxembourg, l’Autriche et neuf autres pays de l’Union européenne présentent un texte demandant la révision ou un nouveau report du règlement contre la déforestation.

Researchers found that between 2002 and 2015, a 3.2% reduction in Brazilian forest cover led to a 5.4% reduction in precipitation levels.

Cette semaine, Actuelles est consacrée aux femmes qui s'engagent pour la défense de la nature. Nous irons à la rencontre de la biologiste marine Fiorella Herrera. Elle a fondé l'association "We can be heroes" pour former les communautés à la protection de la nature et "Salva tu selva" pour protéger 25 000 hectares de forêt primaire en Amazonie péruvienne. Elle raconte ce combat dans un documentaire, "El otro rio".

Tipping elements within the Earth system are increasingly well understood. Scientists have identified more than 25 parts of the Earth’s climate system that are likely to have “tipping points” – thresholds where a small additional change in global warming will cause them to irreversibly shift into a new state. The “tipping” of these systems – which include the Atlantic Meridional Overturning Circulation (AMOC), the Amazon rainforest and the Greenland ice sheet – would have profound consequences for both the biosphere and people. More recent research suggests that triggering one tipping element could cause subsequent changes in other tipping elements, potentially leading to a “tipping cascade”. For example, a collapsed AMOC could lead to dieback of the Amazon rainforest and hasten the melt of the Greenland ice sheet.

Depuis 2016, les banques belges ont accordé plus de 20 milliards d’euros de prêts et de souscriptions à des entreprises posant un grand risque de déforestation.
