Energy return on investment (EROI) is a biophysical and ecological economics concept that is useful to think about how organisms, ecosystems and societies must obtain enough surplus energy returned from energy gathering activities to live, reproduce, and thrive. EROI can help us overcome the false dualism between nature and society. EROI is a useful metric for economics because it is based on immutable physical laws rather than sometimes arbitrary human preferences. It is essential for assessing useful power, energy trade-offs, efficiencies (and inefficiencies), resource depletion trends, resource quality, and surplus potentials of different fuels and technologies that power, or might power, our socio-economic systems. Apparent inconsistencies in the literature can generally be reduced or eliminated by paying careful attention and explicitly stating boundaries and definitions. We argue that proper use of EROI is critical to understand the interconnections among the environment, energy, and socio-economic deve

Le Consortium international des journalistes d’investigation (CIJI) travaillait depuis un an sur ces informations : pas moins de 11 millions de documents, provenant de quatorze cabinets financiers, basés dans des paradis fiscaux comme le Panama, les îles Vierges, Dubaï… Et concernant plus de 29.000 sociétés offshore. L’enquête est baptisée "Pandora Papers", en référence à la boîte de Pandore.

Plants should be flourishing in these ocean waters with plenty of nutrients and inorganic carbon in the form carbonic acid. It could be possible the phytoplankton are missing key nutrients such as ferric, but why should this be happening now?

Les fourneaux du monde brûlent maintenant environ 2 millions de tonnes de charbon par an. Lorsque le charbon est brûlé, qu’il est assemblé à l’oxygène, cela ajoute environ 7 millions de tonnes de dioxyde de carbone dans l’atmosphère chaque année. (…) Ceci tend à faire de l’atmosphère une véritable couverture plus ‘efficace’ pour la planète, ce qui a pour effet d’augmenter sa température. L’effet sera probablement considérable dans quelques siècles.
