Since 1931, Tweed New Haven Airport has sat on a spit of what was once salt marsh and wetlands straddling the New Haven-East Haven border. It is wedged between New Haven Harbor where the Quinnipiac River empties, the Farm River mouth separating East Haven and Branford, and Long Island Sound. It is transected by other waterways – Tuttle Brook and Morris Creek.
(Yale Daily News, 3/7/19) The battle against increased air traffic has been waged by New Haven environmental activists for a decade. Due to recent legislative efforts at the city and state level, this battle seems increasingly dire. Full story here.
Amazon aims to compete with FedEx and UPS in the logistics and shipping industry. That’s what analysts told CNBC after Amazon Air recently expanded to 50 planes and announced it will open a $1.5 billion air hub in Northern Kentucky in 2021. Amazon is handling up to 26% of its own shipping, meaning FedEx, UPS and the U.S. Postal Service are losing a portion of Amazon’s business. FedEx says it’s not worried, but Morgan Stanley reports the major shippers have already lost 2% revenue to Amazon Air. ReadFullArticlehere..
This is the third story in a three-part series on transportation-related air pollution in the Boston area. Read Part 1 here and Part 2 here.
Research from several Boston-area universities shows a kind of air pollution that can lead to heart attacks and strokes is contaminating homes and schools near highways, especially in low-income areas. But it’s not just vehicles on the road that are contaminating local communities with this kind of pollution. Read Full Article here
Wetland soils contain some of the highest stores of soil carbon in the biosphere. However, there is little understanding of the quantity and distribution of carbon stored in our remaining wetlands or of the potential effects of human disturbance on these stocks. Here we use field data from the 2011 National Wetland Condition Assessment to provide unbiased estimates of soil carbon stocks for wetlands at regional and national scales. We find that wetlands in the conterminous United States store a total of 11.52 PgC, much of which is within soils deeper than 30 cm. Freshwater inland wetlands, in part due to their substantial areal extent, hold nearly ten-fold more carbon than tidal saltwater sites—indicating their importance in regional carbon storage. Our data suggest a possible relationship between carbon stocks and anthropogenic disturbance. These data highlight the need to protect wetlands to mitigate the risk of avoidable contributions to climate change.ReadFullArticlehere.
De-icing is defined as removal of snow, ice or frost from a surface (in our instance, plane wings). Anti-icing is understood to be the application of chemicals that not only de-ice, but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.

In regulating aircraft and airports, several compelling interests compete: safety, international commerce, and environmental quality. Of these, safety issues receive perhaps most of the attention, garnering large headlines in the wake of airplane accidents. But the issue of the effect of airports on the environment and human health has heated up in recent years as public interest and citizen groups contest airport expansion on environmental and health grounds, and the airline and airport industries attempt to meet increasingly stringent regulations in these areas.
