GENERAL UNEP/CBD/SBSTTA/16/INF/28 5 April 20121 ENGLISH ONLY SUBSIDIARY BODY ON SCIENTIFIC, TECHNICAL AND TECHNOLOGICAL ADVICE Sixteenth meeting Montreal, 30 April-5 May 2012 Item 7.3 of the provisional agenda* IMPACTS OF CLIMATE-RELATED GEOENGINEERING ON BIOLOGICAL DIVERSITY Note by the Executive Secretary 1. The Executive Secretary is circulating herewith, for the information of participants in the sixteenth meeting of the Subsidiary Body on Scientific, Technical and Technological Advice, a study on the impacts of climate-related geoengineering on biological diversity. 2. This study compiles and synthesizes available scientific information on the possible impacts of a range of geoengineering techniques on biodiversity, including preliminary information on associated social, economic and cultural considerations. The study also considers definitions and understandings of climate-related geoengineering relevant to the Convention on Biological Diversity (CBD). The study has been prepared in response to paragraph 9 (l) of decision X/33, to address the elements of the mandate from that decision which relate specifically to the impacts of climate-related geoengineering on biodiversity. Related legal and regulatory matters are treated in a separate study (UNEP/CBD/SBSTTA/16/INF/29). In addition, a separate consultation process has been undertaken by the Convention on Biological Diversity in order to seek the views of indigenous peoples and local communities on the possible impacts of geoengineering techniques on biodiversity and associated social, economic and cultural considerations (UNEP/CBD/SBSTTA/16/INF/30). 3. This study has been prepared by a group of experts and the Secretariat of the Convention on Biological Diversity, taking into account comments from two rounds of review by Parties, experts and stakeholders.3 4. The key messages are available in all United Nations languages in section II of the note by the Executive Secretary on the technical and regulatory matters on geoengineering in relation to the Convention on Biological Diversity (UNEP/CBD/SBSTTA/16/10). 5. The study has not been formally edited. It will be edited prior to publication in the CBD Technical Series. * UNEP/CBD/SBSTTA/16/1. 1 Reissued to include the Key Messages (as provided in document UNEP/CBD/SBSTTA/16/10) and the table of contents.

Biodiversity, ecosystems and their services are critical to human well-being. Protection of biodiversity and ecosystems requires that drivers of biodiversity loss are reduced. The current main direct drivers of biodiversity loss are habitat conversion, over-exploitation, introduction of invasive species, pollution and climate change. These in turn are being driven by demographic, economic, technological, socio-political and cultural changes. Human-driven climate change due to greenhouse-gas emissions is becoming increasingly important as a driver of biodiversity loss and the degradation of ecosystem services. A rapid transition to a low-carbon economy is the best strategy to reduce such adverse impacts on biodiversity. However, on the basis of current greenhouse-gas emissions, their long atmospheric residence times and the relatively limited action to date to reduce future emissions, the use of geoengineering techniques has also been suggested as an additional means to limit the magnitude of human-induced climate change and its impacts. Proposed climate-related geoengineering techniques 7. In this report, climate-related geoengineering is defined as a deliberate intervention in the planetary environment of a nature and scale intended to counteract anthropogenic climate change

  • Conservation Behavior: Applying Behavioral Ecology to Wildlife Conservation and Management Edited by Oded Berger-Tal and David Saltz Frontmatter More Information
    Cambridge University Press 978-1-107-04010-6 - Conservation Behavior: Applying Behavioral Ecology to Wildlife Conservation and Management Edited by Oded Berger-Tal and David Saltz Frontmatter More information Conservation Behavior Applying Behavioral Ecology to Wildlife Conservation and Management Conservation behavior assists the investigation of species endangerment associated with managing animals impacted by anthropogenic activities. It employs a theoretical framework that examines the mechanisms, development, function and phylogeny of behavior variation in order to develop practical tools for preventing biodiversity loss and extinction. Developed from a symposium held at the International Congress for Conservation Biology in 2011, this is the first book to offer an in-depth, logical framework that identifies three vital areas for understanding conservation behavior: anthropogenic threats to wildlife, conservation and management protocols, and indicators of anthropogenic threats. Bridging the gap between behavioral ecology and conservation biology, this volume ascertains key links between the fields, explores the theoretical foundations of these linkages, and connects them to practical wildlife management tools and concise applicable advice. Adopting a clear and structured approach throughout, this book is a vital resource for graduate students, academic researchers, and wildlife managers. ODED BERGER-TAL is a senior lecturer at the Mitrani Department of Desert Ecology of Ben Gurion University of the Negev, Israel. His research centers upon the integration of behavioral ecology into wildlife conservation and management. DAVID SALTZ is a Professor of Conservation Biology at the Mitrani Department of Desert Ecology, and the director of the Swiss Institute for Desert Energy and Environmental ResearchofBenGurionUniversityoftheNegev, Israel.

  • Mackenzie Climate Change Testimony
    WRITTEN TESTIMONY OF FRED T. MACKENZIE, PH.D. DEPARTMENT OF OCEANOGRAPHY SCHOOL OF OCEAN AND EARTH SCIENCE AND TECHNOLOGY UNIVERSITY OF HAWAI‘I HEARING ON CLIMATE CHANGE IMPACTS AND RESPONSES IN ISLAND COMMUNITIES BEFORE THE SENATE COMMITTEE ON COMMERCE, SCIENCE, AND TRANSPORTATION MARCH 19, 2008 Introduction Good morning Senator Inouye, members of the committee, ladies and gentlemen. Thank you for giving me the opportunity this morning to speak to you on global climate issues and how they might impact island communities. My name is Fred Mackenzie and I am an Emeritus Professor in the Department of Oceanography at the University of Hawai‘i. My research is quite broad in scope but focuses on the behavior of the Earth’s surface system of oceans, atmosphere, land, and sediments through geologic time and its future under the influence of humans, including the problems associated with greenhouse gas emissions to the atmosphere, global warming, and ocean acidification. I have been an academician for more than 45 years and published more than 250 scholarly publications, including six books and nine edited volumes in ocean, Earth and environmental science. Today you have asked me to comment on how climate change might affect island communities and on our recent work developing climate and sustainability case studies for Pacific island resources that can be used to educate and inform the community, including local decision makers. Many of my comments are derived from the report of the Pacific Islands Regional Assessment Group, for which I served as a member, entitled Preparing for a Changing Climate. The Potential Consequences of Climate Variability and Change (Shea et al., 2001), and the case study Climate Change, Water Resources, and Sustainability in the Pacific Basin: Emphasis on O‘ahu, Hawai‘i and Majuro Atoll, Republic of the Marshall Islands (Guidry and Mackenzie, 2006).

It does not deliver new facts and figures, but instead provides a new perspective on the existential risks associated with anthropogenic global warming. It is the critical overview of well-informed intellectuals who sit outside the climate-science community which has developed over the last fifty years. All such expert communities are prone to what the French call deformation professionelle and the German betriebsblindheit. Expressed in plain English, experts tend to establish a peer world-view which becomes ever more rigid and focussed. Yet the crucial insights regarding the issue in question may lurk at the fringes, as BY HANS JOACHIM SCHELLNHUBER this report suggests. This is particularly true when Hans Joachim Schellnhuber is a professor of theoretical the issue is the very survival of our civilisation, physics specialising in complex systems and nonlinearity, where conventional means of analysis may become founding director of the Potsdam Institute for Climate useless.

  • Global Dimming
    Agricultural and Forest Meteorology 107 (2001) 255–278 Review Global dimming: a review of the evidence for a widespread and significant reduction in global radiation with discussion of its probable causes and possible agricultural consequences Gerald Stanhill∗, Shabtai Cohen Institute of Soil, Water and Environmental Sciences, ARO, Volcani Center, Bet Dagan 50250, Israel Received 8 August 2000; received in revised form 26 November 2000; accepted 1 December 2000 Abstract A number of studies show that significant reductions in solar radiation reaching the Earth’s surface have occurred during the past 50 years. This review analyzes the most accurate measurements, those made with thermopile pyranometers, and concludes that the reduction has globally averaged 0.51 0.05 W m−2 per year, equivalent to a reduction of 2.7% per decade, and now totals 20 W m−2, seven times the errors of measurement. Possible causes of the reductions are considered. Based on current knowledge, the most probable is that increases in man made aerosols and other air pollutants have changed the optical properties of the atmosphere, in particular those of clouds. The effects of the observed solar radiation reductions on plant processes and agricultural productivity are reviewed. While model studies indicate that reductions in productivity and transpiration will be proportional to those in radiation this conclusion is not supported by some of the experimental evidence. This suggests a lesser sensitivity, especially in high-radiation, arid climates, due to the shade tolerance of many crops and anticipated reductions in water stress. Finally the steps needed to strengthen the evidence for global dimming, elucidate its causes and determine its agricultural consequences are outlined.

  • Increase in Domestic Electricity Consumption from Particulate Air Pollution
    ARTICLES https://doi.org/10.1038/s41560-020-00699-0 Increase in domestic electricity consumption from particulate air pollution Pan He 1,2,6 ✉ , Jing Liang3,6, Yueming (Lucy) Qiu 3,6 ✉ , Qingran Li4 and Bo Xing5 Accurate assessment of environmental externalities of particulate air pollution is crucial to the design and evaluation of envi- ronmental policies. Current evaluations mainly focus on direct damages resulting from exposure, missing indirect co-damages that occur through interactions among the externalities, human behaviours and technologies. Our study provides an empirical assessment of such co-damages using customer-level daily and hourly electricity data of a large sample of residential and commercial consumers in Arizona, United States. We use an instrumental variable panel regression approach and find that par- ticulate matter air pollution increases electricity consumption in residential buildings as well as in retail and recreation service industries. Air pollution also reduces the actual electricity generated by distributed-solar panels. Lower-income and minority ethnic groups are disproportionally impacted by air pollution and pay higher electricity bills associated with pollution avoid- ance, stressing the importance of incorporating the consideration of environmental justice in energy policy-making. ir pollution has resulted in many types of negative externali- in commercial buildings for longer period of time. These two effects ties, a situation that calls for policy intervention to address can cancel out, and thus we hypothesize that air pollution does not Athe associated damages.

  • Global Climate Change Control: Is There a Better Strategy Than Reducing Greenhouse Gas Emissions?
    GLOBAL CLIMATE CHANGE CONTROL: IS THERE A BETTER STRATEGY THAN REDUCING GREENHOUSE GAS EMISSIONS? † ALAN CARLIN This Article identifies four major global climate change problems, analyzes whether the most prominent of the greenhouse gas (GHG) control proposals is likely to be either effective or efficient in solving each of the problems, and then extensively analyzes both management and technological alternatives to the proposals. Efforts to reduce emissions of GHGs, such as carbon dioxide, in a decentralized way or even in a few countries (such as the United States or under the Kyoto Protocol) without equivalent actions by all the other countries of the world, particularly the most rapidly growing ones, cannot realistically achieve the temperature change limits most emission control advocates believe are neces- sary to avoid dangerous climatic changes, and would be unlikely to do so even with the cooperation of these other countries. This Article concludes that the most effective and efficient solution would be to use a concept long proven by nature to reduce the radiation reaching the earth by adding particles optimized for this purpose to the stratosphere to scatter a small portion of the incoming sunlight back into space, as well as to undertake a new effort to better under- stand and reduce ocean acidification. Current temperature change goals could be quickly achieved by stratospheric scattering at a very modest cost without the need for costly adaptation, human lifestyle changes, or the general public’s ac- tive cooperation, all required by rigorous emission controls. Although strato- spheric scattering would not reduce ocean acidification, for which several reme- dies are explored in this Article, it appears to be the most effective and efficient first step toward global climate change control.
