Scientists observe chimpanzees using human-like warfare tactic

On the boundary of dangerous territory, a troop of about 30 individuals engaging in a border patrol climbs a rocky hill to conduct reconnaissance. Detecting the sounds of adversaries a bit too close for comfort, the squad retreats. There is no reason to risk a fight with the odds against you. It is a scenario that has unfolded innumerable times in the history of human warfare. But in this case, it involved not people but chimpanzees in Tai National Park in southwestern Ivory Coast, West Africa's largest protected area of rainforest.

Explainer-Can solar geoengineering stop global warming?

As the world struggles to renounce its burning of fossil fuels, scientists are studying whether atmospheric geoengineering could help limit warming and avert climate catastrophe. One potential method, solar radiation management (SRM), seeks to reflect the sun's rays back into space, with the most well-known proposal being to blast sulphur dioxide - a coolant - into the higher reaches of the atmosphere.
