collapse of the Kyoto Protocol and the struggle to slow global warming
Even as the evidence of global warming mounts, the international response to this serious threat is coming unraveled. The United States has formally withdrawn from the 1997 Kyoto Protocol; other key nations are facing difficulty in meeting their Kyoto commitments; and developing countries face no limit on their emissions of the gases that cause global warming. In this clear and cogent book-reissued in paperback with an afterword that comments on recent events--David Victor explains why the Kyoto Protocol was never likely to become an effective legal instrument. He explores how its collapse offers opportunities to establish a more realistic alternative.
Global warming continues to dominate environmental news as legislatures worldwide grapple with the process of ratification of the December 1997 Kyoto Protocol. The collapse of the November 2000 conference at the Hague showed clearly how difficult it will be to bring the Kyoto treaty into force. Yet most politicians, policymakers, and analysts hailed it as a vital first step in slowing greenhouse warming. David Victor was not among them.
Kyoto's fatal flaw, Victor argues, is that it can work only if emissions trading works. The Protocol requires industrialized nations to reduce their emissions of greenhouse gases to specific targets. Crucially, the Protocol also provides for so-called \"emissions trading,\" whereby nations could offset the need for rapid cuts in their own emissions by buying emissions credits from other countries. But starting this trading system would require creating emission permits worth two trillion dollars--the largest single invention of assets by voluntary international treaty in world history. Even if it were politically possible to distribute such astronomical sums, the Protocol does not provide for adequate monitoring and enforcement of these new property rights. Nor does it offer an achievable plan for allocating new permits, which would be essential if the system were expanded to include developing countries.
The collapse of the Kyoto Protocol--which Victor views as inevitable--will provide the political space to rethink strategy. Better alternatives would focus on policies that control emissions, such as emission taxes. Though economically sensible, however, a pure tax approach is impossible to monitor in practice. Thus, the author proposes a hybrid in which governments set targets for both emission quantities and tax levels. This offers the important advantages of both emission trading and taxes without the debilitating drawbacks of each.
Individuals at all levels of environmental science, economics, public policy, and politics-from students to professionals--and anyone else hoping to participate in the debate over how to slow global warming will want to read this book.

Metal/covalent‐organic frameworks for electrochemical energy storage applications
Many renewable energy technologies, especially batteries and supercapacitors, require effective electrode materials for energy storage and conversion. For such applications, metal‐organic frameworks (MOFs) and covalent‐organic frameworks (COFs) have been recently emerged as promising candidates. Their high surface area, organized channel, and multiple functions make them highly versatile and flexible as electrodes, electrolytes, and electrocatalysts in electrochemical energy storage (EES) systems. In addition, many MOFs/COFs‐derived materials tend to possess high conductivity and diverse nanoarchitecture, and can also serve as high‐performance electrodes. In this review, we summarize the extensive potentials of both frameworks and their derivatives in a range of devices, including lithium/sodium ion, lithium‐sulfur, lithium‐oxygen batteries, and supercapacitors. In addition, we discuss the remaining challenges in this area and propose potential solutions for them as well as outline a few possible directions for further development for EES applications. Metal/covalent organic frameworks (MOFs/COFs) have received wide attention for electrochemical energy storage (EES) due to their unique structural characteristics. Herein, we summarize the applications of MOFs/COFs and their derivatives in EES, including lithium/sodium ion, lithium‐sulfur, lithium‐oxygen batteries, and supercapacitors. Moreover, the development perspective of MOFs/COFs in EES is also outlined.

Polymer/Metal Organic Framework (MOF) Nanocomposites for Biomedical Applications
The utilization of polymer/metal organic framework (MOF) nanocomposites in various biomedical applications has been widely studied due to their unique properties that arise from MOFs or hybrid composite systems. This review focuses on the types of polymer/MOF nanocomposites used in drug delivery and imaging applications. Initially, a comprehensive introduction to the synthesis and structure of MOFs and bio-MOFs is presented. Subsequently, the properties and the performance of polymer/MOF nanocomposites used in these applications are examined, in relation to the approach applied for their synthesis: (i) non-covalent attachment, (ii) covalent attachment, (iii) polymer coordination to metal ions, (iv) MOF encapsulation in polymers, and (v) other strategies. A critical comparison and discussion of the effectiveness of polymer/MOF nanocomposites regarding their synthesis methods and their structural characteristics is presented.

Exploring the social-ecological systems discourse 20 years later
This paper explores the 20-year evolution of the social-ecological systems framework (SESs). Although a first definition of SES dates back to 1988, Berkes and Folke more thoroughly used the concept in 1998 to analyze resilience in local resource management systems. Since then studies of interlinked human and natural systems have emerged as a field on its own right, promoting interdisciplinary dialogue and collaboration in a wide set of fields and practices. As the SES concept celebrates its 20-year existence we decided to make an overview of how authors use the concept in relation to research that deals with social and ecological linkages. Hence, we conducted a review of the SES concept using the Scopus database, analyzing a random set of journal articles on social-ecological systems (n = 50) regarding definitions of SES, authors’ main sources of inspiration in using the concept, as well as document type, subject area, and other relevant information. Although there is a steady increase of SES publications, we found that 61% of the papers analyzed did not even provide a definition of the term social-ecological system(s), a shortcoming that makes case comparisons difficult and reduces the usefulness of the concept. We also found three common SES frameworks that authors seem to be most commonly inspired by, referred to here as the original, the robustness, and multitier frameworks, respectively. The first can be characterized as a descriptive framework, the latter two more as diagnostic frameworks, useful for modeling. Although it would be a bit presumptuous of us to come up with a more thorough definition of the SES concept in this paper, we urge SES scholars to be more meticulous in making explicit what they mean by a social-ecological system when conducting SES research.

Metal-organic frameworks with photocatalytic bactericidal activity for integrated air cleaning
Air filtration has become an essential need for passive pollution control. However, most of the commercial air purifiers rely on dense fibrous filters, which have good particulate matter (PM) removal capability but poor biocidal effect. Here we present the photocatalytic bactericidal properties of a series of metal-organic frameworks (MOFs) and their potentials in air pollution control and personal protection. Specifically, a zinc-imidazolate MOF (ZIF-8) exhibits almost complete inactivation of
Escherichia coli
(
E. coli
) (>99.9999% inactivation efficiency) in saline within 2 h of simulated solar irradiation. Mechanistic studies indicate that photoelectrons trapped at Zn
+
centers within ZIF-8 via ligand to metal charge transfer (LMCT) are responsible for oxygen-reduction related reactive oxygen species (ROS) production, which is the dominant disinfection mechanism. Air filters fabricated from ZIF-8 show remarkable performance for integrated pollution control, with >99.99% photocatalytic killing efficiency against airborne bacteria in 30 min and 97% PM removal. This work may shed light on designing new porous solids with photocatalytic antibiotic capability for public health protection.
Personal protective air filtration masks are becoming increasingly desirable, but most commercial air purifiers have poor biocidal capabilities. Here the authors fabricate metal–organic framework-based air filters with both high particulate matter removal efficiencies and photocatalytic bactericidal properties.
