Fine particulate matter (PM 2.5) in China at a city level
Yan-Lin Zhang,Fang Cao +1 more
TL;DR: It is found only 25 out of 190 cities could meet the National Ambient Air Quality Standards of China, and the population-weighted mean of PM2.5 in Chinese cities are 61 μg/m3, ~3 times as high as global population- Weighted mean, highlighting a high health risk.

The emergence of Ug99 races of the stem rust fungus is a threat to world wheat production
Ravi P. Singh,David Hodson,Julio Huerta-Espino,Yue Jin,Sridhar Bhavani,P. Njau,S. A. Herrera-Foessel,Pawan K. Singh,Sukhwinder Singh,Velu Govindan +9 more
TL;DR: Although new Ug99-resistant varieties that yield more than current popular varieties are being released and promoted, major efforts are required to displace current Ug99 susceptible varieties with varieties that have diverse race-specific or durable resistance and mitigate the Ug99 threat.

Investigation of the sources and evolution processes of severe haze pollution in Beijing in January 2013
TL;DR: In this paper, a detailed characterization of the sources and evolution mechanisms of this haze pollution with a focus on four haze episodes that occurred during 10-14 January in Beijing was presented, where the main source of data analyzed is from submicron aerosol measurements by an Aerodyne Aerosol Chemical Speciation Monitor.

Surface water inundation in the boreal-Arctic: potential impacts on regional methane emissions
TL;DR: In this article, a satellite data driven model investigation of the combined effects of surface warming and moisture variability on high northern latitude (⩾45° N) wetland emissions, by considering sub-grid scale changes in fractional water inundation (Fw) at 15 day, monthly and annual intervals using 25km resolution satellite microwave retrievals, and the impact of recent (2003-11) wetting/drying on northern CH4 emissions.

In situ detection of biological particles in cloud ice-crystals
Kerri A. Pratt,Paul J. DeMott,Jeffrey R. French,Zhien Wang,Douglas L. Westphal,Andrew J. Heymsfield,Cynthia H. Twohy,Anthony J. Prenni,Kimberly A. Prather +8 more
TL;DR: In this paper, aircraft-aerosol time-of-flight spectroscopy measurements of ice residues indicate that biological particles trigger ice formation in high-altitude clouds, which is one of the largest remaining sources of uncertainty in climate change projections.
