A high profile scientific journal is investigating how it came to publish a study suggesting that global warming is down to natural solar cycles. The paper was criticised by scientists for containing “very basic errors” about how Earth moves around the sun.
The study was published online on 24 June by Scientific Reports, an open access journal run by Nature Research, which also lists the prestigious Nature journal among its titles. A spokesperson told New Scientist that it is aware of concerns raised over the paper, which was authored by five academics based at Northumbria University, the University of Bradford and the University of Hull, all in the UK, plus the Nasir al-Din al-Tusi Shamakhi Astrophysical Observatory in Azerbaijan, and the National Research University Higher School of Economics in Moscow, Russia.
The authors suggest that Earth’s 1°C temperature rise over the past two centuries could largely be explained by the distance between Earth and the sun changing over time as the sun orbits around our solar system’s barycentre, its centre of mass. The phenomenon would see temperatures rise a further 3°C by 2600, they say.
