An assessment of systems, agents, and institutions in building community resilience to climate change: A case study of Charlottetown, Canada
Download2022-01-01
Birchall, S. Jeff, MacDonald, Seghan, Bara, Nicklas N.
While climate change manifests itself as a global phenomenon, impacts are experienced most acutely at the local scale. As a result, the onus of responding to climate change impacts through planning policies and practice falls on local government decision-makers. This qualitative study, based in...

Birchall, S. Jeff, MacDonald, Seghan, Slater, Tara
As climate change progresses, local governments are being forced to find ways to adapt to worsening environmental, economic, and infrastructure impacts. The city of Fredericton, New Brunswick has a long history of river and overland flooding; however, more recent changes in local weather patterns...

Climate change adaptation policy and practice: The role of agents, institutions and systems
Download2021-01-01
Birchall, S. Jeff, Bonnett, Nicole
Surrey, British Columbia, stands out in its efforts to go beyond the provincial mandate on climate change mitigation and incorporate adaptation into strategic planning. The community is not currently overwhelmed by climate change impacts, and has local agents and institutions in place to...

Climate change resilience in the Canadian Arctic: The need for collaboration in the face of a changing landscape
Download2019-12-17
MacDonald, Seghan, Birchall, Jeff S.
Human-induced changes to global climate have become increasingly difficult to ignore in recent years. As the frequency and severity of extreme weather events increases, the impacts on both natural and human systems are becoming difficult to manage with the current policies. In Canada, one of the...

Coastal Climate Adaptation Planning and Evolutionary Governance: Insights from Homer, Alaska
Download2020-01-01
Climate variability is not a new challenge for coastal communities. However, because climate variability is manifesting with more extreme climate impacts, occurring with greater frequency and with more intensity, the necessity for adaptation to minimize risk is becoming more pronounced. Though...

Coastal communities in the Circumpolar North and the need for sustainable climate adaptation approaches
Download2020-08-15
Bonnett, Nicole, Birchall, Jeff S.
Climate change is one of society’s greatest contemporary challenges. Increasing global temperatures leave coastal locations in particular, vulnerable to impacts that include rising sea levels and more extreme and variable weather events. Stress can be acute for small coastal communities located...

Efficient Carbon Recycling at the Central‐Northern Lesser Antilles Arc: Implications to Deep Carbon Recycling in Global Subduction Zones
Download2020-04-23
Li, Kan, Li, Long, Aubaud, Cyril, Muehlenbachs, Karlis
Carbon recycling efficiency of arc (CREA) is an important parameter to assess the recycling of slab carbon into Earth's deep interior. Although previous studies observed variable degrees of recycled slab carbon at global arcs, the CREA value of any individual subduction zone has not been obtained...

Experimental investigation of formation and decomposition of roaldite in ammonia atmosphere at 300–700 °C and associated nitrogen isotope fractionations
Download2021-05-01
Li, Long, Cartigny, Pierre, Li, Kan
Roaldite (Fe4N) is one of the few nitride minerals found in meteorites. Their nitrogen (N) isotopic signatures carry important information for understanding the early N cycle in the proto-solar nebula. However, the lack of knowledge on the N isotopic effects from nitride formation to its survival...

First-principles calculations of equilibrium nitrogen isotope fractionations among aqueous ammonium, silicate minerals and salts
Download2021-03-15
Li, Yonghui, Li, Long, Wu, Zhongqing
Nitrogen isotopes are a robust tool to study geological nitrogen cycle between Earth’s reservoirs. However, the application of nitrogen isotope system to understanding geological processes has been limited by the lack of constraints on equilibrium isotope fractionation factors between mineral and...

In situ oxidation of sulfide minerals supports widespread sulfate reducing bacteria in the deep subsurface of the Witwatersrand Basin (South Africa): Insights from multiple sulfur and oxygen isotopes
Download2022-01-01
Li, Long, Wei, Siwen, Lollar, Barbara Sherwood, Wing, Boswell, Bui, Thi H., Ono, Shuhei, Lau Vetter, Maggie C. Y., Onstott, Tullis C., Kieft, Thomas L., Borgonie, Gaetan, Linage-Alvarez, Borja, Kuloyo, Olukayode, van Heerden, Esta
Dissolved sulfate is a crucial electron acceptor for the subsurface biosphere, particularly for the living microbial ecosystems in the long-isolated (on the order of millions to billions of years) deep subsurface fracture waters in Precambrian cratons, e.g., in the Witwatersrand Basin of the...
