The methane detectives: On the trail of a global warming mystery – “The bottom line is that methane is going up and doesn’t look like it will stop anytime soon”

By Jonathan Mingle 13 May 2019 (Undark) – Every week, dozens of metal flasks arrive at NOAA’s Earth System Research Laboratory in Boulder, Colorado, each one loaded with air from a distant corner of the world. Research chemist Ed Dlugokencky and his colleagues in the Global Monitoring Division catalog the canisters, and then use a series of […]

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns – “We are watching this sleeping giant wake up right in front of our eyes”

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns – “We are watching this sleeping giant wake up right in front of our eyes”

30 April 2019 (University of Guelph) – A “sleeping giant” hidden in permafrost soils in Canada and other northern regions worldwide will have important consequences for global warming, says a new report led by University of Guelph scientist Merritt Turetsky. Scientists have long studied how gradual permafrost thaw occurring over decades in centimetres of surface […]

Temporal distribution of insect biomass at selected locations in nature protection areas in Germany, 1989-2016. (A) Daily biomass (mean ±1 se) across 26 locations sampled in multiple years (see S4 Fig for seasonal distributions). (B) Distribution of mean annual rate of decline as estimated based on plot specific log-linear models (annual trend coefficient = −0.053, sd = 0.002, i.e. 5.2% annual decline).

Three-quarters of the total insect population lost in protected nature reserves – “Whatever the causal factors responsible for the decline, they have a far more devastating effect on total insect biomass than has been appreciated previously”

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 […]
