For a tern in the northern hemisphere, life may be about to take a turn for the worse. For murres or guillemots, as the temperature rises, the chance of survival takes a dive. Many of the world’s seabirds could be in trouble. And for a mix of reasons, the birds of the southern hemisphere could also be heading into difficulties, but at a slower pace. A worldwide team of 40 Ornithologists has looked at 50 years of breeding records for 67 seabird species to find that as global temperatures notch up, breeding rates are down. That may be just an indicator of deteriorating conditions on and below the surface of the oceans: the researchers call their seabird subjects “ecosystem sentinels”. The scientists report in the journal Science that they used their data to test a proposition: that seabird productivity − the numbers that survive each breeding season − would track “hemispheric asymmetry” in ocean climate change and human use.

The world is running out of time to reach an ambitious deal to stem the destruction of the natural world, the co-chair of negotiations for a crucial UN wildlife summit has warned, amid fears of a third delay to the talks. Negotiators are scheduled to meet in Kunming, China, in October for Cop15, the biggest biodiversity summit in a decade, to reach a hoped-for Paris-style agreement on preventing wildlife extinctions and the human-driven destruction of the planet’s ecosystems. The summit was meant to take place in October last year but has been delayed twice due to the coronavirus pandemic.
