An ancient Egyptian kingdom close to the Nile collapsed more than 4,200 years ago because it failed to adapt to climate change, according to new research.
During Egypt’s Old Kingdom - the pyramid-building time - 4,200 years ago, droughts and fires plagued the region, causing famine and social unrest.
Scientists examined 7,000-year-old ancient pollen and charcoal samples from the Nile to piece together the time - and found evidence of a 'mega drought' in the the area.
The Great Pyramid in Giza was built by Egyptians between 2560-2540BC
'This study illustrates that water availability was the climate-change Achilles Heel then for Egypt, as it may well be now, for a planet topping seven billion thirsty people.'
The researchers examined the presence and amount of charcoal, as fires increase during times of drought leaving charcoal in the geological records.

One of those events was the abrupt and global mega-drought around 4,200 years ago, which led to famines and probably played a role in the end of Egypt’s Old Kingdom and affected other Mediterranean cultures.
These events are also recorded in history - the first about 5,000 years ago when the unification of Upper and Lower Egypt happened and the Uruk Kingdom in modern Iraq collapsed, the Geology study says. The second event 3,000 years ago took place in the eastern Mediterranean and is associated with the fall of the Ugarit Kingdom and famines in the Babylonian and Syrian Kingdoms.
Christopher Bernhardt, of the USGS, said: 'Humans have a long history of having to deal with climate change.

Professor Benjamin Horton, of the University of Pennsylvania, said: 'The study geologically demonstrates that when deciphering past climates, pollen and other micro-organisms, such as charcoal, can augment or verify written or archaeological records - or they can serve as the record itself if other information doesn’t exist or is not continuous.'
