Researchers find ‘alarming’ effect on fertility across global species from simultaneous exposuresSimultaneous exposure to toxic chemicals and climate change’s impacts likely generates an additive or synergistic effect that increases reproductive harm, and may contribute to the broad global drop in fertility, new peer-reviewed research finds.The review of scientific literature considers how endocrine-disrupting chemicals, often found in plastic, coupled with climate change’s effects, such as heat stress, are each linked to reductions in fertility and fecundity across global species – including in humans, wildlife and invertebrates.

Covid, light pollution regulations and faltering global economy affect location and intensity of brightnessEarth continues to get brighter every year, researchers have found, but the location and intensity of the progression has become increasingly volatile because of Covid-19, regulations on light pollution, and a faltering global economy.Nasa-funded researchers at the University of Connecticut (UConn) studied more than 1.1m satellite images taken over a nine-year period to establish that the planet’s artificial light increased by a net 16% between 2014 and 2022.
