César DUCRUET French National Centre for Scientific Research (CNRS) Abstract The analysis of historical vessel movements is proposed in this paper to compare recent Northeast Asian port and maritime dynamics with previous development stages back to the late nineteenth century. The changing distribution of vessel calls at and between Northeast Asian ports reveals important shifts of maritime connectivity over time, from the emergence of Japan as the dominant player in the region to a present-day more complex pattern with Hong Kong, Busan, and Shanghai as the major hubs. -
Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future
Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future As more and more states are incorporating projections of sea-level rise into coastal planning efforts, the states of California, Oregon, and Washington asked the National Research Council to project sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account the many factors that affect sea-level rise on a local scale. The projections show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections; north of that point, sea-level rise is projected to be less than global projections because seismic strain is pushing the land upward. ny significant sea-level In compliance with a rise will pose enor- 2008 executive order, mous risks to the California state agencies have A been incorporating projec- valuable infrastructure, devel- opment, and wetlands that line tions of sea-level rise into much of the 1,600 mile shore- their coastal planning.

Biogeographical Diversity of Alpine Tundra Vegetation in the Oceanic Regions of Northeast Asia
©Reinhold-Tüxen-Gesellschaft (http://www.reinhold-tuexen-gesellschaft.de/) Ber. d. Reinh.-Tüxen-Ges. 19, 117-129. Hannover 2007 Biogeographical Diversity of Alpine Tundra Vegetation in the Oceanic Regions of Northeast Asia - Y. Nakamura, Tokyo & P.V. Krestov, Vladivostok - Abstract The Arctic tundra zone and alpine vegetation belt are characterized by a complex of dwarf-shrub, graminoid and herbaceous tundra communities that occur in conditions of heat deficit and a very short growing season. The effects of these climatic factors in different habitats are strongly controlled by topography. Generally, tundra plant com- munities occupy their own microhabitats with peculiar environmental conditions that create the highly diverse vegetation mosaic in alpine belts. In oceanic regions of Northeast Asia, alpine vegetation occurs from the temperate to boreal zones of Japan and Russia. This paper focuses on the most peculiar representatives of six alpine vege- tation classes. Phytosociological diversity of tundra communities is described, in first approximation, with special reference to their biogeographical distributional patterns. 1. Introduction According to traditional understanding of vegetation zonation in northern Asia, tundra, as a vegetation type, is characteristic to polar deserts and Arctic tundra zones and to the upper vegetation belts of large mountain systems in the temperate, boreal and subarctic zones. In northeastern Asia, only Wrangell and Gerald Islands are in the zone of Arctic Deserts (KOLESNIKOV 1961), which are characterized by lack of a closed vegetation cover. Large areas on these islands are covered by talus or rock outcrops. Crustose and foliose lichens (species of Gyrophora, Lecidea, and Rhizocarpon) are most abundant on the rocky substrates. -

OCEAN WARMING • the Ocean Absorbs Most of the Excess Heat from Greenhouse Gas Emissions, Leading to Rising Ocean Temperatures
NOVEMBER 2017 OCEAN WARMING • The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. • Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals. • Rising ocean temperatures also affect the benefits humans derive from the ocean – threatening food security, increasing the prevalence of diseases and causing more extreme weather events and the loss of coastal protection. • Achieving the mitigation targets set by the Paris Agreement on climate change and limiting the global average temperature increase to well below 2°C above pre-industrial levels is crucial to prevent the massive, irreversible impacts of ocean warming on marine ecosystems and their services. • Establishing marine protected areas and putting in place adaptive measures, such as precautionary catch limits to prevent overfishing, can protect ocean ecosystems and shield humans from the effects of ocean warming. The distribution of excess heat in the ocean is not What is the issue? uniform, with the greatest ocean warming occurring in The ocean absorbs vast quantities of heat as a result the Southern Hemisphere and contributing to the of increased concentrations of greenhouse gases in subsurface melting of Antarctic ice shelves. the atmosphere, mainly from fossil fuel consumption. The Fifth Assessment Report published by the Intergovernmental Panel on Climate Change (IPCC) in 2013 revealed that the ocean had absorbed more than 93% of the excess heat from greenhouse gas emissions since the 1970s. This is causing ocean temperatures to rise. Data from the US National Oceanic and Atmospheric Administration (NOAA) shows that the average global sea surface temperature – the temperature of the upper few metres of the ocean – has increased by approximately 0.13°C per decade over the past 100 years. -

Harnessing Remote Sensing Derived Sea Level Rise Models to Assess Cultural Heritage Vulnerability: a Case Study from the Northwest Atlantic Ocean
sustainability Article Harnessing Remote Sensing Derived Sea Level Rise Models to Assess Cultural Heritage Vulnerability: A Case Study from the Northwest Atlantic Ocean Meghan C. L. Howey 1,2 1 Department of Anthropology, University of New Hampshire, 73 Main Street, Durham, NH 03824, USA; [email protected] 2 Earth Systems Research Center, Institute for the Study of Earth, Oceans, and Space, University of New Hampshire, 8 College Road, Durham, NH 03824, USA Received: 20 October 2020; Accepted: 10 November 2020; Published: 12 November 2020 Abstract: Climate change threatens cultural heritage across the globe. Of its varied impacts, sea level rise is critically pressing because of the long relationship between humans and the ocean. Numerous cultural heritage sites lie on the world’s fragile coasts. Identifying cultural heritage sites at risk is an urgent need, but archaeological research programs do not always have the resources available to conduct large-scale cultural heritage vulnerability assessments. Given sea level rise poses myriad pressing issues, entities around the globe are developing sea level rise models for various management purposes (ecology, hydrology, real estate, etc.). These remote sensing-derived sea level rise models can be harnessed by archaeologists to assess cultural heritage site vulnerability. Here, such an analysis is realized for a northwest Atlantic Ocean coastal area experiencing relative sea level rise and with robust cultural heritage, including economically significant maritime heritage tourism. Combining archaeological and historic geospatial databases with LIDAR (Light Detection and Ranging)-derived relative sea level rise models illuminates coastal New Hampshire’s cultural heritage vulnerability. This is informative for risk monitoring, mitigation, and preservation planning, especially for cultural heritage tourism. -

The Paris Agreement has initiated a scientific debate on the role that carbon removal – or net negative emissions – might play in achieving less than 1.5 K of global mean surface warming by 2100. Here, we probe the sensitivity of a comprehensive Earth system model (GFDL-ESM2M) to three different atmospheric CO2 concentration pathways, two of which arrive at 1.5 K of warming in 2100 by very different pathways. We run five ensemble members of each of these simulations: (1) a standard Representative Concentration Pathway (RCP4.5) scenario, which produces 2 K of surface warming by 2100 in our model; (2) a “stabilization” pathway in which atmospheric CO2 concentration never exceeds 440 ppm and the global mean temperature rise is approximately 1.5 K by 2100; and (3) an “overshoot” pathway that passes through 2 K of warming at mid-century, before ramping down atmospheric CO2 concentrations, as if using carbon removal, to end at 1.5 K of warming at 2100. -
Sea Level Rise Assessment
Sea Level Rise on Bainbridge Island A Preliminary Assessment Manitou Beach, December 20, 2018, 3:40 pm. Water level: 9.91 ft NAVD88 (12.25 ft MLLW). Report to the City of Bainbridge Island, Climate Change Advisory Committee October 24th, 2019 1 Acknowledgements The Climate Change Advisory Committee was established in 2017 by the City Council of Bainbridge Island to take action on climate change and increase the community’s resilience (Ordinance no. 2017- 13). The Committee’s work plan calls for an evaluation of climate impacts and recommendations to the City for adaptation and mitigation actions. The following document fulfills Action 10.1 in the 2019-20 Draft Work Plan, which specifically calls for an evaluation of the vulnerability of City assets and other infrastructure to the impacts of sea level rise. Identified by the Committee as a high priority action item, this report is also intended to provide a template for subsequent assessments. The principal author of and photographer for this report is James Rufo Hill, who began the effort while serving on the Climate Change Advisory Committee. This report builds upon the 2016 Bainbridge Island Climate Impacts Assessment, which was written by Lara Hansen, Stacey Nordgren, and Eric Mielbrecht. Finally, generous assistance was provided by City of Bainbridge Island staff, especially Christy Carr and Gretchen Brown. Thank you, all. 2 Contents Summary: page 4 Introduction: page 5 Methods: page 8 Results: page 10 Discussion: page 18 References: page 20 Appendix: page 21 3 Summary Among climate change impacts, sea level rise stands out because even if humans stopped emitting greenhouse gases today, global oceans would continue to absorb excess heat, expand, and rise for centuries (Clark et al 2016).
