Rigorous, informative and thorough - an excellent examination of climate change science - By: J. Aitcheson, 21 May 2008 
The Very Short Introduction series by Oxford University Press has a good reputation for presenting challenging subjectsin an easily accessible manner. Mark Maslin's "Global Warming: A Very Short Introduction" is a timely addition to the series, tackling what is arguably the dominant issue of our age.
After providing an overview of the history of the global warming debatein science & the media, Maslin examines the underlying psychology behind different popularly-held views of our climate, arguing whether we see Nature as, for example, resilient or fragile is conditioned by our world-view (individualist or collectivist; fatalist or optimist). While this is an interesting diversion, & adds a new spin on the debate, it is presentedin a confusing manner & threatens to put the reader off before the book has even properly begun. This would be a shame, however, for Maslin provides an excellent analysis of the evidence for global warming, examining the methods - past & present - usedin gathering climate data (balloons, boreholes, satellites etc) & how these are collated to create a coherent picture of our global climate.
More than simply a presentation of the case that global warming exists, however, Maslin provides an insight which is both fair & balanced, highlighting some of the more contentious issues, while skilfully discrediting the main arguments posed by sceptics. At the same time, though, he is careful to concede that there are some areas which climate change science has not yet taken into consideration. One such concerns the effects of galactic cosmic raysin stimulating the formation of clouds - the effects of which on warming or cooling the planet are still not fully understood themselves. Maslin also points out areasin which there is still a large degree of uncertainty - such as the exact magnitude of future temperature increases & sea-level rises - as well as the limitations of current climate modelsin projecting the future.
Climate change is seen throughout the book as a gradual, linear process, & it is only late on that the author discussesin depth possible 'surprises' - abrupt events which could have a sudden & catastrophic effect on our climate, such as the potential shutdown of the global oceanic conveyor, or the release of gas hydrates into the atmosphere. Much research has gone into these subjects, & one feels that just 15 pages - only 2 on gas hydrates - is insufficient to cover them properly. Indeed climate change researchin general has moved on apace since the book's first publicationin 2004; the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) was released earlyin 2007, thus superseding much of the information - provided by AR3in 2001 - on which this book is based.
The text is supplemented by no less than 38 illustrations & diagrams, serving for the most part to elucidate the themes presented, although some may be difficult for the lay reader to interpret. Disappointing is the list of suggested further reading, which includes only 18 titles & makes it difficult to use this book as a springboard for finding out more. As an alternative introduction to the subject, however, I can highly recommend Robert Henson's "The Rough Guide to Climate Change", the second, revised edition of which was published earlyin 2008 & which does incorporate the new findings from IPCC AR4. Even more compelling than either Maslin or Henson, however, is Bill McGuire's "Global Catastrophes: A Very Short Introduction", the first half of which directly concerns anthropogenic (human-induced) climate change, & illustrates through the impacts global warming is likely to have exactly why this is an issue we should be deeply concerned about.
Everything considered, "Global Warming: A Very Short Introduction" is - a few minor shortcomings aside - a rigorous & convincing primer on what is a challenging & often contentious subject.
Excellent review, with some original ideas too - well worth the modest investment in time and money - By: Mr. Nicholas J Robertson, 12 Jan 2008 Professor Maslin has written a wide ranging, comprehensive & reasonably balanced review of global warming theory, despite declaring himself part of "the consensus" pretty early on. His 150 or so pages are an excellent summary, covering the greenhouse effect hypothesis, its history, evidence that warming is already happening, thoughts on how we might mitigate its effects, political problems & eventual solutions. Much of the material is from the IPCC's Third Assessment Report (so perhaps an update is on the way) although Maslin bringsin other material as well. The most innovative of the chapters dips into the psychology of global warming acceptance/scepticism, & while this may not be a normal part of a geographer's repertoire it is thought provoking all the same. There is quite a lot on storms - this appears to be one of Maslin's own areas of research, & here he is more qualified about stating causative links. He also comments on press coverage, contrasting the Guardian (for which he was a contributor) with The Times, which was more sceptical.
Maslin puts the sceptics case fairly & courteously, although mainly to seek to disprove it or to seize on those elements of global warming theory that sceptics have conceded. While he names many of the consensus thinkers by name, however, he mentions few sceptics; while he does cover the theory of "Chilling Stars", for example, & even gives it an abbreviation (GCRs = Galactic Cosmic Rays), Henrik Svensburg is not mentionedin the text.
He has not, I am afraid, moved me much from my "don't know to moderately sceptical that warming is man-made" position. For example, he accepts the importance of water-vapour as a greenhouse gas, & goes on to accept that water-vapour & the mechanism for cloud formation is one of the least well understood processes. It seemed to me that the next step was to admit that this meant that there was a great deal less certaintyin the climate models as they currently stand than some suggest. I was disappointed, too, (as it was one of my purposesin reading the book) that he does not explain any experimental basis quantitatively linking increased CO2 with increased temperature. The computer models (which he explainsin concept, though notin individual detail) must have a formula (amongst many) to the effect that "additional 100 ppm CO2 = a temperature rise of x degrees C". You will be none the wiser as to how the (many different) values of "x" might have been calculated.
This was the first of OUP's "A Very Short Introductions" that I have read; there were 133 of them listed I this 2004 edition. I shall certainly read more, but would like to suggest to OUP that they print themin a slightly larger format - at 7" x 4.5" they are rather smaller than standard paperbacks these days & the print is unnecessarily small. While written by a scholar, the book does not give footnotes so it is not easy to establish exactly where a particular fact or argument originates.
That though, is a minor quibble. Overall, an excellent summary with a few original ideas of Maslin's own.
A Very Good Introduction - By: , 06 Jul 2005 
It's very striking that at least three of Amazon's top 20 books on global warming represent only the sceptical / George W Bush view, which is supplied mostly by economists funded by oil companies rather than publicly-funded climate scientists as it happens. Are readers earnestly searching for a balanced view, or is it that we prefer to read books that confirm our hopes & allow us to go on with our lives reassured?
This little book makes two major contributions to the debate. First it conveys all the essential information about global warmingin an accurate & accessible way, soundly basedin the author's extensive experiencein paleoclimatic studies. But at least as important is the wayin which it engages with climate change scepticism, showing how it is basedin real scientific argument as well as self-serving dismissal. The arguments of sceptics are fairly represented, with some points frankly conceded & other rebutted with the help of the latest scientific evidence. But as well as arguing the specific claims, the author shows how the debate reflects deeper divisions between participants regarding conceptions of nature & risk. So for example sceptics might view nature as basically resilient, even eternal, thus discounting environmental risks compared with environmentalists who view it as basically fragile & transient. In other words, as well as trying to resolve some of the arguments about global warming, he shows how some are effectively insolublein purely scientific terms. If you're after real balance, rather than ideologically-motivated reassurance, you can find it here.
