The European Environment Agency's latest Air quality in Europe report reveals that, in 2013, air pollution was responsible for 467,000 premature deaths in European cities (Phys.org). The report analysed data from over 400 cities in 41 European countries and found that particulate matter - tiny particles of dust and soot that primarily result from fossil fuels - are a particular hazard to city dwellers' health, entering the lungs to cause respiratory problems and even penetrating the bloodstream. 16 per cent of European urbanites are exposed to particulate levels above EU targets. However, air quality is improving overall, and the report notes that "emissions of the main air pollutants in Europe have declined in recent decades, resulting in generally improved air quality across the region".

Researchers working with sediment core dating have found that the Antarctic's Pine Island Glacier began melting in the 1940s (BBC). Changes to the immense glacier, which has detached from its ice shelf and contributes to greater sea level rise than any other ice stream melt, were dated by identifying the presence of plutonium traces, the result of atomic bomb tests in the years following the Second World War. Analysis of the sediment layers reveals that warm ocean water first got under the ice shelf in the 1940s, beginning its current decay.
