The perennial question following any extreme weather event is whether climate change is responsible for the event in question. Until recently, the short answer to this question was ‘No’ but recent findings suggest that this answer needs to be refined. It is still not possible to state categorically that climate change has caused a specific event, and natural variability continues to play a key role in extreme weather. But climate change, through rising temperatures and water vapour levels for example, is changing the odds of extreme events occurring. The last couple of years have certainly seen a large number of extreme events take place, from the floods in Queensland, Colombia, Pakistan and Sri Lanka, to the droughts in Texas, Australia, China and the Amazon, and record-setting high temperatures in countries that cover approximately one-fifth of the Earth’s surface. Wildfires, snowstorms, tornadoes and hurricanes have also made the headlines in a number of countries. This has led to the appearance of new expressions: ‘global weirding’ and ‘a new normal’.

It is within this context that Dr James Powell, whose book 2084: An Oral History of the Great Warming is reviewed here, aims to find out whether there is now a ‘preponderance of evidence’ showing that climate change is truly under way, a situation which he argues warrants a response. He focuses on extreme weather for a number of reasons. Weather is what we experience on a daily basis and is therefore more tangible than some vague notion of climate change in distant countries or futures. Additionally, extreme weather can prove very costly in terms of lives, livelihoods and infrastructures, and we therefore all have a stake in taking preventative measures. Finally, and perhaps most importantly, increases in the occurrence of events such as extreme temperatures are the best harbingers of climate change. This is clearly illustrated in figure 1 below. With this in mind, the author frames the issue as one of risk management and compares it to the insurance industry: we take out insurance not because of a high probability of fire or burglary, but because we stand to lose a lot if we are uninsured and such an event takes place. Similarly, Powell argues, increasing and/or intensifying extreme events would require action to be taken – we should aim to ‘avoid the unmanageable and manage the unavoidable’.

After providing some background on recent events in the prologue, the author explains the science behind climate change and its possible links with extreme weather. This is an important step as it begins to answer the question ‘Why are scientists predicting that global warming will cause intensifying and/or increasing extreme weather events?’ This then provides a platform from which to analyse and look at the specifics behind recent events. In doing this, Powell shows how science proceeds from a testable hypothesis whose basis, in this case, lies in basic physics: rising temperatures should lead to an increase in water vapour levels. In turn, this additional heat and moisture should provide the perfect setting for the development of more, and more intense, storms. And so the stage is set: the hypothesis and assumptions are described and the case can now be built block by block.

The book is then organised in short chapters that each tackle a specific event or related extreme weather events – heat, drought, fire, rain and snow, floods, tornadoes, and hurricanes. Powell is meticulous in his research and these chapters read like investigative reports, looking at events and placing them in their historical context, before looking at the evidence that helps determine whether climate change has played a role. And like all good scientific reviewers, the author is not afraid to discuss scientific uncertainties and diffculties which make attribution studies such a complex task. But this is more than a simple description of the mechanisms behind extreme weather. Powell discusses the resulting damage and suffering inherent to such events. This helps bring the message home: extreme events are more than abstract physical phenomena. They are some of the most destructive disasters than can hit you, and their toll can reach tens of thousands of deaths and billions of US dollars. If the overall impact of events paints a bleak picture, the personal stories are particularly harrowing. Unlike 2084, these are events which have already taken place and wreaked havoc on the lives and livelihoods of thousands of people. And Powell’s personal account of the 1988 Yellowstone National Park fires somehow makes these events more tangible, particularly if you are lucky enough to never have faced such destructive forces.

Powell also addresses issues that have arisen, or could arise, from the responses and management of extreme events. For instance, the action taken by the Army Corps of Engineers to manage the 2011 Mississippi floods could have led to the river reverting to its alternate course, through the Atchafalaya Basin, an event which would have considerable impacts on downstream communities and shipping. Clearly, this did not happen this time, but should we run the risk of causing such a change again, or do we need to think of alternative solutions to manage future problems? Also, during the heatwaves in Europe (2003) and Russia (2010), people lost their lives because they did not know that they had to drink more water in warmer conditions or because they drowned after drinking alcohol. This clearly shows that simple measures, such as awareness campaigns, could yield significant results and allow us to protect ourselves against the worst effects of such events, which helps to address the issues behind ‘managing the unavoidable’.

But the overall strength of his argument lies perhaps in the evaluation of predictions made by climate scientists. With rising water vapour levels now observed, is the expected increase in extreme precipitation events already noticeable? It appears so: analyses of US and northern hemisphere precipitation show just this. Similarly, changes in the timing of snow melt, and rising sea-surface and air temperatures have been implicated in wildfires, droughts and heatwaves. But at no point does Powell claim that climate change alone is responsible for all events in recent years. This is particularly true of tornadoes and hurricanes. Not only does he clearly state the uncertainties, he also points out other factors, such as river engineering projects, La Niña and forestry practices, that have played major, sometimes predominant, roles in some of the events he discusses. This is openness at its best, a way of pre-emptively answering those critics who tend to cherry-pick details and miss the whole picture when evaluating climate-related evidence.

So does Powell manage to answer the questions he sets out to answer, namely whether there is now a ‘preponderance of evidence’ that climate change is under way? He certainly makes his position clear: for him, there is already enough evidence to take action and prevent the worst from occurring. It is difficult to argue against this. Of course, extreme events have always occurred, without the help of humans, but it is the number of recent record-breaking events or worst events in decades that should make us stand up and take note. These come on top of trends that show rising global temperatures, melting Arctic sea ice, retreating glaciers, rising sea levels, and migrating species. All of this is consistent with what we expect from climate change. So do we now wait until we have absolute proof, which probably means leaving it too late to ‘avoid the unmanageable’, or do we start addressing the root cause of all these changes?

Rough Winds was released as a Kindle Single and is currently at #3 under Earth Science. The good news is that you don’t need a Kindle to read it – you can download apps to read it on PC, Mac, iPhone/iPad and Android. With the Horn of Africa and Pakistan experiencing severe drought and floods, respectively, as well a new La Niña possibly on its way, this is a timely book that I thoroughly recommend.

JR:   Climate Progress has reviewed two of Powell’s recent e-books — see “A review of 2084: An Oral History of the Great Warming” andThe Inquisition of Climate Science: A Scientist Exposes the Business of Denial.

So I decided to splurge, and drop $.99 for this e-book.  Powell actually cites both of those reviews as “jacket quotes” in his new e-book, so he’s definitely a CP reader.  If he’s looking for a new quote, try this:  Powell’s “Rough Wind” is just the kind of e-book you should send anyone who wants to get up to speed on the staggering weather extremes of the past year and their connection to global warming.  It would be a steal at twice the price.  Okay, that last bit was humor.  Be aware that the “book” is only 47 pages, so it is about 2 cents a page, a bargain of sorts compared to full-size books, which are 5 times as long but cost 10 times as much.

My only criticism is that the book should have more active links.  It is very spotty in that regard, yet it really isn’t very hard to add them in.  In particular, Powell appears to rely on Climate Progress reporting in a number of places and it would be nice to have mentions and links.   I don’t think CP readers will see much in the book that they haven’t seen here.  But, as I said, it’s more of a highly readable pamphlet for newbies that you might want to introduce to the subject.

    Thanks for the review- Amazon recommended this to me a few days ago- will download.

    James Hansen ay Worldwide Climate day in NYC said

    “Climate change — human-made global warming — is happening,” he said. “It is already having noticeable impacts. … If we stay on with business as usual, the southern U.S. will become almost uninhabitable.”

  2. Paul Magnus says:

    “…almost uninhabitable.” GOP will jump all over this…:)

  3. Spike says:

    The BBC reports that serious monsoon flooding is now affecting 2 million Indians, as well as Pakistan

    I’ll assume you’re right that he did meticulous research. But, until the real pros–the capitalist insurance industry–ratifies these catalogues of weather events in the form of rate increases, Powell’s kind of research is not likely to change attitudes in the media or political worlds.

    IMO, your occasional reporting on the insurers’ (e.g. Munich Re) response to changing global weather is an order of magnitude more persuasive than any of these weather catalogues. I see an awful lot of weather events in the climate literature. I sure like to see more about how the insurance industry is responding.

    The insurance industry is reality based by definition, reality based or bankrupted.
    And they can do the math.

    wouldn’t you say the ‘Great Migration’ to the ‘Sunbelt’ is just about done? It should begin reversing by 2020.

    Thank you. I bought my copy of this single over the weekend, and thought that the graphs looked quite good on my small-sized Kindle.
