Exclusive: As wildfires rage, Frank Elderson says more work needed to assess risk from collapse of ecosystem services

And why when we do see it, we fail to act.

Récemment, des chercheurs britanniques et étasuniens ont mené une étude majeure démontrant que des catastrophes biologiques d’ampleur se produisent lorsque le rythme des changements environnementaux dépasse la vitesse d’adaptation biologique des espèces. Dans le cadre de leurs travaux, les scientifiques ont analysé des grandes crises qui se sont déroulées lors des 450 derniers millions d’années.

Members of parliament have demanded full publication of an explosive report by the UK’s spy leaders that found the collapse of ecosystems overseas would have catastrophic consequences for the UK’s national security, warning that the UK has “no future” if the findings are not urgently acted on.

A vast system of Atlantic currents that delivers warmth to northern Europe is at risk of collapse, according to a growing body of research. The latest study to warn of its demise finds there is at least a 10 percent chance that a collapse may already be “locked in.”

For most of the modern era, capitalism justified itself through growth. Industrial societies converted vast amounts of fossil energy into production, wealth, and rising living standards. Roads, bridges, power grids, schools, and public institutions expanded alongside the economy. Inequality and exploitation remained deeply embedded in the system, but they were partly obscured by a broader story of material progress.

Climate scientists warn of unprecedented Antarctic heatwave, with temperatures 20C above normal. Loss of sea ice threatens marine life and penguins.

Cette présentation propose des bases pour la collapsologie, en tant que discipline en devenir.
