Changes in Arctic climate variability and extremes may have significant impacts for migratory birds, according to a study presented at EGU23 by Nomikos Skyllas, a PhD student from the University of Groningen. Many species cross continents during their seasonal migration patterns, travelling from as far as Africa and South America to northern regions such as Siberia and the Canadian Arctic.

120 years ago in 1901, Swedish meteorologist Nils Ekholm used the term ‘greenhouse’ to describe the heating effect that a planet’s atmosphere has on the surface temperature of the planet, the first time that this now much-used and abused metaphor was published. He wrote: “The atmosphere plays a very important part of a double character as to the temperature at the earth’s surface, of which the one ...[Read More]
