2025

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.

Meer dan 250 wetenschappers, bekende Belgen en burgerbewegingen roepen in een open brief van 11.11.11, Bond Beter Leefmilieu en Canopea de Vlaamse en Federale onderhandelaars op om ambitieus klimaat- en natuurbeleid centraal op te nemen in de regeringsnota. Want de klimaatopwarming is in een stroomversnelling geraakt, met alle rampzalige gevolgen vandien.
Carbon Brief provides an updated analysis of when the world will likely exceed the Paris 1.5C limit
Climate Obstruction Across Europe, coordinated by the Climate Social Science Network (CSSN), is the first book to document the development and nature of climate obstruction activities across Europe, which are efforts to deliberately slow or block climate action. Climate obstruction strategies range from outright denial to more subtle forces of delay and the spread of disinformation
China’s CO2 emissions fell by 3% in March 2024, ending a 14-month surge that began when the economy reopened after the nation’s “zero-Covid”
Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.
Carbon Brief explores which countries are or have targets to be net-negative, and the moral and scientific arguments for such a milestone.

Analyse · La responsabilité historique du changement climatique est radicalement modifiée lorsque l’on tient compte des émissions de CO2 générées par les anciennes puissances coloniales dans les territoires qu’elles contrôlaient. L’Europe a ainsi un impact beaucoup plus important que ne le laissent penser les modes de calcul actuels.
Historical responsibility for climate change is radically shifted when colonial rule is taken into account, Carbon Brief analysis reveals.
In een Open Brief aan de Nederlandse en Belgische ministers van Landbouw en Volksgezondheid bekritiseren 158 Nederlandse en 132 Belgische wetenschappers de ernstige tekortkomingen in de risicobeoordeling van de onkruidverdelger glyfosaat door de Europese Commissie. Zij vragen een nieuwe beoordeling van de risico's van glyfosaat, zo meldt de Bond Beter Leefmilieu.
