Navigating The U.S. Transition To Sustainability: Matching National Governance Challenges With Appropriate Legal Tools, John Dernbach

John C. Dernbach

Sustainable development would require the United States to maintain and improve human prosperity while at the same time greatly reducing its consumption of energy, materials, water, and land. The scope of the challenge includes, but is not limited to, climate change. This Article suggests the elements of a legal structure for achieving sustainability.

Because achieving sustainable development is a significant learning experience, the United States will need to employ a form of governance—reflexive governance—that requires constant learning and supportive citizens and stakeholders who are also working to ensure sustainability in their own activities. The two basic problems reflexive governance must …

Achieving Early And Substantial Greenhouse Gas Reductions Under A Post-Kyoto Agreement, John Dernbach

John C. Dernbach

This article explains why policy makers should seriously consider substantial early reductions in greenhouse gas emissions as a part of any post-Kyoto framework, and sets out suggested elements of a framework for early action in a post-Kyoto agreement. Substantial early reductions are needed because of the growing urgency of the climate change science, the precautionary approach identified in the Framework Convention on Climate Change as a decision-making principle, the fact that cost-effective measures are now available, and the significant non-climate benefits (security, economic, social, and environmental) that can be achieved by implementing them. As a practical matter, too, long-term greenhouse …

This poster reports on the August 2007 Black Sea Expedition of the Institute for Archaeological Oceanography at the University of Rhode Island (IAO) and the Institute for Exploration (IFE), in collaboration with the Department of the Underwater Heritage of Ukraine. This year’s work marks a new phase in a multi-year (2000–2012) archaeological and oceanographic survey of the Black Sea. 2007 fieldwork focuses on two Byzantine shipwrecks. The 10th century C.E. shipwreck Chersonesos A (discovered in 2006) lies at 140 m depth in the suboxic zone off the Crimean peninsula. The ship carried a cargo of one-handled jars of a widely …

The Formation Of Sporadic E Layers By A Vortical Perturbation Excited In A Horizontal Wind Shear Flow, G. G. Didebulidze, Levan Lomidze

Levan Lomidze

The formation of the mid-latitude sporadic E layers (Es layers) by an atmospheric vortical perturbation excited in a horizontal shear flow (horizontal wind with a horizontal linear shear) is investigated. A three-dimensional atmospheric vortical perturbation (atmospheric shear waves), whose velocity vector is in the horizontal plane and has a vertical wavenumber kz≠0, can provide a vertical shear of the horizontal wind. The shear waves influence the vertical transport of heavy metallic ions and their convergence into thin and dense horizontal layers. The proposed mechanism takes into account the dynamical influence of the shear wave velocity in the horizontal wind on …

Different Long-Term Trends Of The Oxygen Red 630.0 Nm Line Nightglow Intensity As The Result Of Lowering The Ionosphere F2 Layer, N. B. Gudadze, G. G. Didebulidze, Levan Lomidze, G. Sh. Javakhishvili, M. A. Marsagishvili, M. Todua

Levan Lomidze

Long-term observations of total nightglow intensity of the atomic oxygen red 630.0 nm line at Abastumani (41.75° N, 42.82° E) in 1957–1993 and measurements of the ionosphere F2 layer parameters from the Tbilisi ionosphere station (41.65° N, 44.75° E) in 1963–1986 have been analyzed. It is shown that a decrease in the long-term trend of the mean annual red 630.0 nm line intensity from the pre-midnight value (+0.770±1.045 R/year) to its minimum negative value (−1.080±0.670 R/year) at the midnight/after midnight is a possible result of the observed lowering of the peak height of the ionosphere F2 layer electron density hmF2 …
