Oil has empowered capitalism, and some of the world’s most exploitative regimes. Move away from it and we can solve some of the key issues we face
What is currently happening in Brussels under the guise of regulatory simplification is being presented as something technical and logical. Less regulatory pressure, more competitiveness. A series of so-called omnibus bills are intended to streamline legislation. Reporting obligations are being limited and reassessments of raw materials postponed. It sounds like administrative efficiency. In Washington, things are moving even faster: Trump is dismantling the basis for climate laws while the world continues to warm up. The framing is the same: rules slow down businesses, and a slowed-down business community makes us poor. But that reasoning assumes something that is not true: that everyone wants the same thing from the market.
Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world
The world seems headed into another El Nino, just 3 years after the last one. Such quick return normally would imply, at most, an El Nino of moderate strength, but we suggest that even a moderately strong El Nino may yield record global temperature already in 2026 and still greater temperature in 2027. The extreme warming will be a result mainly of high climate sensitivity and a recent increase of the net global climate forcing, not the result of an exceptional El Nino, per se. We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury.

HAMBOURG — Depuis quelque temps déjà, les climatologues débattent d’une hypothèse inquiétante : le réchauffement climatique est-il en train de s’accélérer ? La Société allemande de physique et la Société météorologique allemande mettent désormais en garde contre ce phénomène dans une déclaration commune. L’hebdomadaire allemand Die Zeit s’est entretenu à ce sujet avec Klaus Richter, président de la Société allemande de physique, et Frank Böttcher, président de la Société météorologique allemande.
With warming set to pass the critical 1.5-degree limit, scientists are warning that the world is on course to trigger tipping points that would lead to cascading consequences — from the melting of ice sheets to the death of the Amazon rainforest — that could not be reversed.
The decline in the health of nature around the world poses a threat to the UK's security and prosperity, an intelligence committee has concluded in a long-awaited report. The document warns of "cascading risks" from the degradation of some of the planet's most important ecosystems, including conflict, migration and increased competition for resources.
Like living beyond your financial means, using more water than nature can replenish can have catastrophic results.
Flagship report calls for fundamental reset of global water agenda as irreversible damage pushes many basins beyond recovery
