Increasing snow depth prevented wintertime soils from cooling during the warming hiatus
Scientists investigated snow cover along with other direct and indirect soil temperature influences in northeastern China. The research further showed that the increasing snow depth in northeastern China may be the main reason for the continued warming trend in soil temperatures. In addition to the thermal insulation effect of snow cover, the ability for soil to record human changes and environmental influences, or ''soil memory'' is also important, especially at greater depths.

Local emissions amplify regional haze and particle growth
A Finnish-Chinese research team performed simultaneous measurements of aerosol composition and particle number size distributions at ground level and at 260 m in central Beijing, China, during a total of 4 months in 2015-2017. The team found concentration of both primary and secondary particles in the accumulation mode would decrease drastically, and the haze formation would be reduced if the emission cuts are higher than 30%.

Leading cardiovascular organizations call for urgent action to reduce air pollution
Air pollution is a key risk factor for cardiovascular disease, and a major contributor to the global burden of disease. Long-term exposure to air pollution has also been linked to an increased risk of death from COVID-19. This dangerous 'triple threat' of air pollution, COVID-19 and cardiovascular disease should be taken seriously, warn major health authorities. (2021-01-28)

Light pollution linked to preterm births, reduced birth weights
Researchers discovered that light pollution is linked to preterm birth, a shortened gestational length, and reduced birth weight. babies born too early have higher rates of death and disability. In 2018, preterm birth and low birth weight accounted for roughly 17% of infant deaths (deaths before one year of age). Researchers hope this spawns policy discussion around minimizing light pollution. (2021-01-28)

Chan School of Public Health study. (2021-01-28)

More than just CO2: It's time to tackle short-lived climate-forcing pollutants
Climate change mitigation is about more than just CO2. So-called 'short-lived climate-forcing pollutants' such as soot, methane, and tropospheric ozone all have harmful effects. Climate policy should be guided by a clearer understanding of their differentiated impacts. (2021-01-27)

Historically redlined neighborhoods are more likely to lack greenspace today
Historically redlined neighborhoods are more likely to have a paucity of greenspace today compared to other neighborhoods. The study by researchers at Columbia University Mailman School of Public Health and the University of California, Berkeley and San Francisco, demonstrates the lasting effects of redlining, a racist mortgage appraisal practice of the 1930s that established and exacerbated racial residential segregation in the United States.

Air purifiers may do more harm than good in confined spaces with airborne viruses
The positions of air inlets and outlets in confined spaces, such as elevators, greatly affect airborne virus transmission. In Physics of Fluids, researchers show air purifiers may actually increase the spread. They use ultraviolet radiation to kill viruses and other microbes, but they also circulate air, sucking it in and exhausting cleaned air. This adds to overall circulation. (2021-01-26)

Mangroves threatened by plastic pollution from rivers, new study finds
Mangrove ecosystems are at particular risk of being polluted by plastic carried from rivers to the sea. Fifty-four per cent of mangrove habitat is within 20 km of a river that discharges more than a tonne of plastic waste a year into the ocean, according to a new paper published in the journal Science of the Total Environment. Mangroves in southeast Asia are especially threatened by river-borne plastic pollution, the researchers found. (2021-01-26)

Dramatic increase in microplastics in seagrass soil since the 1970s
Large-scale production of vegetables and fruit in Spain with intensive plastic consumption in its greenhouse industry is believed to have leaked microplastic contaminants since the 1970s into the surrounding Mediterranean seagrass beds. This is shown in a new study where researchers have succeeded in tracing plastic pollution since the 1930s and 1940s by analyzing seagrass sediments. (2021-01-25)

Reactive halogen from domestic coal burning aggravates winter air pollution
During the winter in the North China Plain, scientists found high concentrations of reactive halogen gases (BrCl, HOBr, Cl2) in the atmosphere which was associated with widespread coal burning in rural areas. Halogen atoms released from BrCl and Cl2 under sunlight significantly increased the oxidative capacity, and has the potential to boost the productions of secondary aerosols - the major components of winter haze in northern China - and the toxic form of mercury.

Butterfly wing clap explains mystery of flight
The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers at Lund University in Sweden have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a highly effective clap technique, therefore making use of their unique wings. This helps them rapidly take off when escaping predators. (2021-01-20)

Disposable helmet retains cough droplets, minimizes transmission to dentists
Dentists and otolaryngologists are at particular risk of infection of COVID-19, since they need direct access to the mouth, nose, and throat of patients. The current solutions are expensive, not highly effective, and not very accessible. In Physics of Fluids, researchers discuss their design of an open-faced helmet that is connected to a medical-grade air filtration pump from the top that creates a reverse flow of air to prevent cough droplets from exiting the helmet.
