Ancient Egyptians believed in coiffure after death
Conflict appears more likely in warmer years
Because you’re worth it when you’re dead ANCIENT Egyptians wouldn’t be caught dead without hair gel. Style in the afterlife was just as important as it was during life on Earth – and coiffure was key. To this end, men and women alike had their tresses styled with a fat-based “gel” when they were embalmed. The evidence has been found in a community cemetery dating back 3000 years. Tomb paintings depict people with cone-shaped objects sitting on their heads, thought to be lumps of scented animal fat. “Once we started

One possibility is that international markets spread climate signals around the world. For instance, widespread drought in an El Niño year could cause global food prices to rise.
But as Andrew Solow of the Woods Hole Oceanographic Institution in Massachusetts points out, “People do not start wars simply because they are hot.” And until we know what it is about El Niño that increases the likelihood of conflict, it will be impossible to say whether this means we should expect more unrest due to climate change.
