The Seneca Rebound: Why Growth is Faster after Collapse. Explaining the European World Dominance

What made Europeans so successful in the task of conquering the world? My interpretation is that it was the result of periodic “Seneca Collapses” of the European population which made it possible to accumulate resources that would then be available to propel the European expansion. It is an effect that may be called the”Seneca Rebound” that makes growth faster after a collapse.

The Midterms were Good for Climate Candidates but Disastrous for the Climate

Democrats campaigning on climate action and clean energy did very well around the country election night. It’s clearly a winning issue, as the polls have long said. But two key results of the election are bad news for the climate — and together they pose a very difficult challenge to the kind of near-term climate action that’s needed to avoid catastrophic climate change.

Churches as Key Actors on Climate Change?

In principle, churches and congregations are hubs where people gather organically. Being places where people gather organically, faith communities are existing hubs where folks can be more naturally inspired to collaborate toward bigger goals that escape the short reach of individuals.

Combining Renewables with Direct Air Capture for ‘Net Negative’ Emissions

But what if the dual challenges facing renewables and negative emissions could be tackled together? In a recent paper, published in Earth’s Future, we find that there is considerable potential for combining a renewables-reliant electricity system with Direct Air Capture.

Instead of Decoupling, we need Recoupling

The path to meaning – and real sustainability – is the opposite; it is through recoupling with nature. Instead of denying that we are an integral part of nature in which we swim, live, mate, laugh, cry and die, we need to embrace that fact.

A Modest Investment with Major Dividends: Cycling Culture in the Netherlands

How would you describe the process in which a small country builds a 35,000 kilometer network of fully separated bike infrastructure – and traffic-calms 75 per cent of their urban streets to a speeds of 30 km/h (19 mph) or less?
