Researchers have a responsibility to search for consensus on this crucial issue, both for future generations and the future of our planet go.nature.com/4ymEN7N

The problem is not too little growth, but the wrong kind. What matters is not how much we grow, but what we grow — and for whom. Our response in @financialtimes.com to @jburnmurdoch.ft.com Bottom line: economic and climate justice require rethinking growth, not necessarily abandoning it.

The income of someone in the world’s richest region is on average about 13x higher than someone in the poorest. But the corresponding figure for education spending (per child) reveals an even starker 40:1 ratio, writes @ricardo-eco.bsky.social of @wid.world #LSEInequalitiesBlog buff.ly/9LqVQC3

“Inequality is a political choice” The 56,000 wealthiest adults on the planet hold 3x as much wealth as the poorest half of humanity combined – but two policy levers could help redress the balance. @ricardo-eco.bsky.social of @wid.world explores #LSEInequalitiesBlog buff.ly/hT0Avna
