It is hard not to have noticed the intensity of storms around the world this year, not least the Atlantic storms that battered the eastern US. A new study, using a new technique, confirms their attribution to climate change, and goes further, finding that many of them were actually raised in intensity category compared to how strong they might have been in a world without anthropogenic climate change. The costs are already extraordinary, according to Daniel Gilford of Climate Central in Princeton.

When it comes to wildlife conservation, one of the underestimated parameters is the 鈥渙ld and wise鈥� individuals in a population. According to a review paper in the journal Science, not only are earth鈥檚 old animals in decline, in many species they are vital to recovery and resilience when outside factors endanger numbers. As co-author Lauren Brent of Exeter University points out, these sorts of nuance are not always looked out for in conservation estimates.

Chimps have culture, but is their culture cumulative and transmissible or innate and intuitive? Comparing a large database of observed chimpanzee behaviours, together with genetic lineages, Cassandra Gunasekaram and Andrea Migliano, of the University of Zurich, found that types of more complex tool usage can be correlated with reproductive overlaps between different chimp communities. The wandering females maybe carry tech knowledge with them when they travel to find new mates. Is this something both chimps and humans inherited from a common ancestor?

And finally, as the harvesting of deep ocean polymetallic nodules gets nearer to commercial reality, the French research ship L鈥橝talante sets sail this week to study the animals that live on and around these strange chemical balls scattered across the abyssal plains of the mid pacific ocean. As lead scientist aboard, Pierre-Antoine Dessandier tells us, it is essential to understand how these animals live in the dark, 5km down, before the habitats are disturbed. The Eden mission will be searching the Clarion-Clipperton zone until January 2025.
