An influential panel of scientists voted this week to designate a new geologic epoch — the Anthropocene — to mark the profound ways in which humans have altered the planet. The proposal would still have to be approved by the International Commission on Stratigraphy, which oversees the official geological time chart. The start of the Anthropocene would be linked to the first atomic-bomb blasts, which littered the globe with radioactive debris that left its mark on the geologic record.

An Alabama law putting a total ban on abortion joins a slate of eight similar laws in the United States (none of which has yet come into effect). Wired explores how such restrictions might affect women’s physical health, looking at research on what has happened in other countries. In Romania, for example, maternal mortality rates spiked to 150 women per 100,000 births after abortion and contraception was made illegal in 1966 — and fell by 50% in the first year after they were legalized again, in 1989.

Applying ‘nudge’ theory to influence people to reduce their carbon emissions could end up eroding support for more painful, but more impactful, carbon-tax policies. In multiple experiments, researchers asked people to imagine themselves as policymakers and to choose whether to implement a carbon tax, a green-energy nudge for consumers or both. They found that nudges decreased support for the tax, possibly “by providing false hope that problems can be tackled without imposing considerable costs”. The good news: support for a carbon tax went back up when people were informed that nudges can supplement, but not replace, more transformative changes.
