Climate change effects on birds Last Updated on 2014-09-06 19:35:56 Many birds species all over the world are highly sensitive to the effects of climate change. Scientists have found declines of up to 90 percent in some bird populations, as well as total and unprecedented reproductive failure in others, althought the role of any change in climate is typically not determined. Population declines generally have several associative causal factors including habitat loss, habitat fragmentation and pollution. Specific groups that are at high risk from climate change include migratory birds, mountain birds, island birds,   wetland   birds, Arctic birds, Antarctic birds and seabirds. Bird species that can move easily to new habitat are expected to continue to do well; however, bird species that thrive only in a narrow environmental range can be expected to decline, and to be outcompeted by invasive species. With a 0.8°C average... More »
Management and Conservation of Wildlife in a Changing Arctic Environment Last Updated on 2014-07-07 18:45:12 This is Chapter 11 of the Arctic Climate Impact Assessment Lead Author: David R. Klein; Contributing Authors: Leonid M. Baskin, Lyudmila S. Bogoslovskaya, Kjell Danell, Anne Gunn, David B. Irons, Gary P. Kofinas, Kit M. Kovacs, Margarita Magomedova, Rosa H. Meehan, Don E. Russell, Patrick Valkenburg Climate changes in the Arctic in the past have had major influences on the ebb and flow in availability of wildlife to indigenous peoples and thus have influenced their distribution and the development of their cultures.Trade in animal parts, especially skins and ivory of marine mammals, and trapping and sale of fur-bearing animals go far back in time. Responsibility for management and conservation of wildlife in the Arctic falls heavily on the residents of the Arctic, but also on the global community that shares in the use of arctic resources. A sense of global stewardship toward the... More »
Introduction to Management and Conservation of Wildlife in a Changing Arctic Environment Last Updated on 2014-07-07 18:26:28 This is Section 11.1 of the Arctic Climate Impact Assessment Lead Author: David R. Klein; Contributing Authors: Leonid M. Baskin, Lyudmila S. Bogoslovskaya, Kjell Danell, Anne Gunn, David B. Irons, Gary P. Kofinas, Kit M. Kovacs, Margarita Magomedova, Rosa H. Meehan, Don E. Russell, Patrick Valkenburg What can be learned from present wildlife management systems in the Arctic that can be drawn upon to alter existing systems or to design new ones to more effectively deal with climate-induced changes, and other changes that may occur in the future? Climate is the driver of change that has been the primary focus of the Arctic Climate Impact Assessment, however, it is important to remember that changes from other causes are also underway within the Arctic and that these are also affecting arctic ecosystems, as well as the economies, lifestyles, and dependency on wildlife of people in the...

Lifestyle, technology and CO2 emissions in China Last Updated on 2014-06-28 17:59:40 Introduction China as the world’s largest developing country and the most populous country has achieved notable success in developing their economy with approximate 10 percent average annual growth of GDP over the last two decades [1-3]. Large sections of the population have been experiencing a transition from ‘poverty’ to ‘adequate food and clothing’; today growing parts of the population are getting closer to ‘well to do’ lifestyles [3]. However, the rapid growth of the economy has not only lead to dramatic changes of wealth and people’s lifestyle, but has also caused a huge amount of resources and energy consumption and associated CO2 and other emissions creating serious environmental problems on both local, regional and global scales [4-6]. Between 1990 and 2004 China’s total energy consumption has grown 5.0% annually from... More »
Key findings, science gaps, and recommendations for freshwater ecosystems in the ACIA Last Updated on 2014-06-24 17:51:50 This is Section 8.8 of the Arctic Climate Impact Assessment Lead Authors: Frederick J.Wrona,Terry D. Prowse, James D. Reist; Contributing Authors: Richard Beamish, John J. Gibson, John Hobbie, Erik Jeppesen, Jackie King, Guenter Koeck, Atte Korhola, Lucie Lévesque, Robie Macdonald, Michael Power,Vladimir Skvortsov,Warwick Vincent; Consulting Authors: Robert Clark, Brian Dempson, David Lean, Hannu Lehtonen, Sofia Perin, Richard Pienitz, Milla Rautio, John Smol, Ross Tallman, Alexander Zhulidov In general, changes in climate and UV radiation levels in the Arctic are very likely to have far-reaching impacts, affecting aquatic species at various trophic levels, the physical and chemical environment that makes up their habitat, and the processes that act on and within freshwater ecosystems. Interactions of climatic variables such as temperature and precipitation with freshwater... More »
