Expedition was drawn to Nikumaroro after spotting what was described as a metallic glint in waters off uninhabited island

A US expedition that voyaged to a remote Pacific island in the hope of solving the mystery of what happened to pioneering pilot Amelia Earhart has said an object they suspected to be her plane was a clump of washed-up trees.

“Unfortunately, we weren’t able to find that smoking gun,” said Steve Schultz of Purdue University, standing on the sand in front of a blue lagoon on the atoll of Nikumaroro, about halfway between Australia and Hawaii.

Images from New Zealand aerial survey of Nikumaroro in 1938 offer new clues over aviator’s disappearance

A New Zealand museum has released nearly 50 photos from a 1938 aerial survey of the island where Amelia Earhart is believed to have crash-landed, offering amateur sleuths new evidence to scour for traces of the pioneering aviator and her plane.

The black-and-white images were published by the Air Force Museum of New Zealand after renewed interest in one of the biggest mysteries of the 20th century, spurred by a US expedition to the Pacific atoll of Nikumaroro in search of new clues.

Researchers will head to remote Pacific atoll, but sceptics say satellite images unlikely to be of her aircraft

A team of US researchers is approaching a remote Pacific atoll where they suspect the famed aviator Amelia Earhart crash-landed in 1937, in the latest attempt to crack one of the biggest mysteries of the 20th century.

The 17-person expedition was inspired by satellite images taken over several years showing a submerged object in the uninhabited island’s sandy lagoon – evidence dismissed by other longtime Earhart sleuths who say it is probably a fallen tree.

‘The climate issue is the security issue,’ says Turkish minister at Pacific pre-Cop summit in Fiji

Wealthy countries should spend far more on dealing with the climate crisis than the 5% of GDP promised by Nato members for defence because “the climate issue is the security issue”, the host of the next UN summit has said.

But, in comments that are likely to prove contentious, the Cop31 president-designate, Murat Kurum, hedged on whether countries should try to repeat a previous agreement to “transition away from fossil fuels” – the primary cause of the climate crisis – when they meet in Turkey next month.
