18 October 2017 (IWWR) – Since 1989, in 63 nature reserves in Germany the total biomass of flying insects has decreased by more than 75 percent. This decrease has long been suspected but has turned out to be more severe than previously thought. Ecologists from Radboud University together with German and English colleagues published these […]
30 April 2016 (NOAA) – The annual greenhouse gas index (AGGI) is a measure of the warming influence of long-lived trace gases and how that influence is changing each year.

13 June 2015 (Desdemona Despair) – Data show that growth of human carbon emissions in the modern era is pretty close to exponential (cf. “Graph of the Day: Global carbon emissions from fossil fuels, 1751-2013”). But what about carbon emissions per person? The Carbon Dioxide Information Analysis Center (CDIAC) maintains a database of fossil-fuel CO2 […]
July 2010 (Chesapeake Bay Foundation) – Oyster harvests tumbled by two-thirds between the 1890s and 1930, but then remained relatively stable at a lower level until the 1950s. Then a pair of diseases hit. MSX and Dermo are both caused by parasites that attack and frequently kill oysters, although they are harmless to people. Compounded […]
