A staple of dystopian science fictions is an inner sanctum of privilege and an outer world – chemical desert/airless waste/District 12 – peopled by the desperate poor. The insiders, living off the exploited labour of the outlands, are indifferent to the horrors beyond their walls. Well, here we are.

Even as extreme heat raged across the southern United States this summer, the governors of Florida and Texas struck down heat protections for outdoor workers. Construction companies and agricultural firms lobbied against the rights of workers to water, shade and rest breaks when temperatures soar – and Ron DeSantis and Greg Abbott, two men also lavishly funded by the fossil fuel industry, gave them what they wanted.

Our former environment correspondent had solar panels installed in 2010 and later added a heat pump. He’s totted up the energy generated and cash saved over the years

An abiding memory of a day in August 2010, the first time my solar panels were connected to the grid, was of the builders downing tools and watching the electricity meter whiz round backwards.

It was a sunny day and they were supposed to be finishing the plastering and insulation, but the novel sight of the old-style electricity meter in reverse was too entertaining.

The Australian sea lions glide and dart through underwater tunnels, over seagrass beds and rocky reefs, searching for a meal and dancing with dolphins around a giant bait ball of fish – all the action captured by a camera stuck on their back.

“I can watch this stuff for hours,” says Prof Simon Goldsworthy. “It’s like the best slow TV ever. You just don’t know what you’re going to see next.”
