It is generally accepted within the scientific community that anthropogenic emissions of greenhouse gases are primarily responsible for a recent warming in global climate and that current trajectories of emissions may lead to potentially catastrophic changes in climate. While reduction in emissions of greenhouse gases, and particularly carbon dioxide, could lead to a stabilisation of global temperatures, this requires international agreements which have yet to be achieved. A possible alternative, which has been widely mooted is to use methods known as geoengineering as an alternative way of limiting increases in global temperature. Geoengineering techniques fall into two main categories of carbon dioxide removal and solar radiation management; within each of these there are a number of options.

Following on from "Carbon Capture" (volume 29 in this series), Geoengineering of the Climate System presents an overview of the technologies currently being considered as large scale solutions to climate change, and considers some of the possible benefits and disadvantages of each. Invited contributions have been received by many of the leading experts on these technologies, and the volume provides a comprehensive overview of both carbon dioxide reduction and solar radiation management methods. These give rise to important ethical and governance issues which are also explored.

Written with active researchers, postgraduate students and policy-makers in mind, the latest addition to the Issues in Environmental Science & Technology series presents a balanced and informed view of this important field of research and is an essential addition to any environmental science library.

Autorentext

The series has been edited by Professors Hester and Harrison since it began in 1994.

Professor Roy Harrison OBE is listed by ISI Thomson Scientific (on ISI Web of Knowledge) as a Highly Cited Researcher in the Environmental Science/Ecology category. He has an h-index of 54 (i.e. 54 of his papers have received 54 or more citations in the literature). In 2004 he was appointed OBE for services to environmental science in the New Year Honours List. He was profiled by the Journal of Environmental Monitoring (Vol 5, pp 39N-41N, 2003). Professor Harrison's research interests lie in the field of environment and human health. His main specialism is in air pollution, from emissions through atmospheric chemical and physical transformations to exposure and effects on human health. Much of this work is designed to inform the development of policy.

Now an emeritus professor, Professor Ron Hester's current activities in chemistry are mainly as an editor and as an external examiner and assessor. He also retains appointments as external examiner and assessor / adviser on courses, individual promotions, and departmental / subject area evaluations both in the UK and abroad.
