Well, I could just say 'We' can't agree on literally anything, why would something as complex as 'climate change' be any different? Doctor, can a 'man' get pregnant? I dunno! Even widely viewed videos yield astoundingly divergent 'narratives' about what was just seen. And that is just two recent examples. In almost every significant arena of human inquiry-- disagreement even on what seem to be incontrovertible 'facts', (much less what to 'do; about them) is increasingly the norm.
I wrote a bunch below before I got tired of it all. Overall the book is slightly dated (2009) but still a highly worthwhile, thoughtful and generally even-handed deep dive into just how complex the answer to the question posed actually is. You could just say it all come down to 'depends on whose ox is gored' and move on I guess, but you'd miss a diverting (though frustrating) journey. Read on for details you may or may not care about.
A whole lot to unpack here! I find some real common ground with Mike Hulme, he's just a few years older than me so we both went through this almost unfathomable transition with respect to a key component of our scientific discipline, climatology. What was once an obscure and almost unknown corner of the atmospheric sciences was transitioned into THE defining issue of our time. As he puts it (p. 333) it climate change has become |the greatest/defining/most serious|* long term |problem|challenge|threat|* (* delete as desired) to humanity. Climatologists are at the forefront of the debate and while my career took me out of climate research I retained a growing and sometimes incredulous fascination with the increasingly existential threat posed by something I though I 'knew' and we all sort of took for granted. There are now entire Departments of Climate Studies' (over 400 higher education institutions are part of the Climate Leadership Network) in perhaps hundreds (or more) universities and under a variety of disciplines. As Hulme points out it is lot more than the weather!
I enjoyed the chapter on the 'Discovery of Global Warming' which features six scientists who played in influential role in bringing this issue to light:
John Tyndall - The 19th-century Irish physicist who first experimentally demonstrated the absorptive properties of greenhouse gases (specifically water vapor and CO2) in 1859.
Svante Arrhenius - The Swedish chemist who, in 1896, calculated how much a doubling of atmospheric CO2 would increase global temperatures—the first quantitative estimate of climate sensitivity.
Guy Callendar - English engineer who, in 1938, revived interest in the greenhouse effect by linking rising industrial CO2 emissions to a measured upward trend in global temperature.
Charles Keeling - American geochemist who established the Mauna Loa Observatory in 1957, providing the first continuous, high-precision record of rising atmospheric carbon dioxide (the 'Keeling Curve').
Syukuro Manabe - A Japanese-American physicist-meteorologist at Princeton in climate modeling who in the late 1960s early 70s developed the some of the first atmospheric models simulating the climate response to changing CO2.
Wally Broecker - American geochemist at Columbia U. often credited with popularizing the term "global warming" in the mid-1970s and identifying the potential for abrupt, non-linear climate shifts.
Obviously, some big names are omitted from this list (Joseph Fourier, Roger Revelle, James Hansen, et al.) but interesting nonetheless.
Later chapters include discussion on numerous topics that 'intersect' the climate change issue in ways that I had really thought about much or internalized.
Science - (how knowledge is constructed, uncertainties, and the role of the IPCC)
Economics -(cost-benefit analyses, discounting the future, and the Stern Review)
Ethics - religion, and philosophy (questions of justice, stewardship, and meaning)
Psychology and sociology - (risk perception, fear, denial, and cultural framing)
Politics and development - (global North-South divides, power dynamics, and international negotiations)
Media and communication - (how narratives are shaped)
The good thing about Mike Hulme's book is that he looks at seemingly every side of this 'issue' (it is often way more than a single issue as he points out) but that also becomes a bit of a problem. Every idea or proposition is sort of viewed as equally valid or useful which I do not believe is the case. See? We already disagree! I was especially irritated with his explanation on how science should be performed. Specifically the section on 'post-normal' strategies for understanding these complex problems. Indigenous or traditional knowledge (p. 81) on such things as weather forecasting? Please. Yet Hulme refuses to say 'no we cannot rely the ____ tribe' for giving answers to these complex problems, or even guidance. Sure they can say 'our forefathers knew when it was going to be dry that year due to the bark on the trees' or other such nonsense but none of it can be verified in any known way, or at least using the methods of science that got us to here. Perhaps that is the problem as many would certainly aver. Or the reliance on people's 'feelings' to guide critical policy decisions. A substantial portion of the U.S. population is demonstrably mentally ill if you use drug prescriptions as a proxy for that. We are supposed to follow their dictates? Or his apparent embrace (or at least refusal to condemn or dismiss) using the legal system (Kivalina, AK v. ExxonMobil Corp. 2008, p. 306) to solve these problems. Our legal system is particularly ill-suited to finding answers to complex scientific questions with it's binary 'winner/loser' paradigm and guaranteed to create a resistance among whoever loses. In addition, numerous judges have proven themselves nothing less than political activists in this country. And the 'losers' in any judgement may be in the millions or even billions. Exxon may make a nice fat target but it employs tens of thousands, has a large retiree class and millions of stockholders. All will become losers if lawsuits to blame climate change on them succeed. And that is just the tip of the (melting) iceberg! We might as well sue ourselves, which actually makes more sense since everyone (including the lawyers getting filthy rich off class-action lawsuits) is complicit in the 'crime'.
As he points out rightly I think, 'climate change may prove ultimately a crisis of governance'. That could not be worse news as the political systems in this country and others I am pretty familiar with (UK, France, Germany) are fragmented almost beyond hope, with political parties (people) unable or unwilling to even look at very basic facts with anything like a common point of view and some political parties are effectively banned from public discourse. Frankly however his political analysis (p. 308) on the failures of democracy to make effective decisions about these profoundly difficult issues was probably correct. Only authoritarian governments seems able to make big decisions (good or bad), He quotes British historian Eric Hobsbawm 'Democracy, however desirable, is not an effective device for solving transnational or global problems'. He is exactly correct which is why the ruling elites in the West (e.g. the EU) would love to suppress all dissent and rule as a one-party technocratic 'state'. Technocratic rule by a ruling oligarchy (i.e. the China model) is the example that much of the West seems wont to emulate.
The fact that the book is closing in on 20 years (2009) is both a weakness and a strength. There is considerable analysis of the pros and cons of 2005 Kyoto Protocol but it would be interesting to see how it compares with the 2015 Paris Agreement. A lot has changed since the Paris 'Agreement' and of course Trump's two withdrawls from it. The deindustrialization of Europe, namely Germany (CO2 emissions down ~50% since 1990 and now 1.6% of global total) has accelerated to the point that Europe will soon be close to a non-factor in the global arithmetic. The rise of the global South has continues apace and the impact of China is clear--in several areas. China is now easily #1 in global CO2 emissions (32% of global total in 2023, per IEA) and is now 2nd in the world in per capita CO2 production passing the entire EU but there are indications that it may be nearing a peak in 2025-2030 (15.1-15.2 GtCO2e). However, total emission China is still 3 times higher than the US. So the problem is not going away and never mind India.
Conflicting goals when it come to climate change (policy targets, carbon markets, social revolution, poverty reduction, R&D conflicts, environmental goals, population control, global government, geoengineering). Four 'myths' of climate change-1) nostalgia, the lament of Lost Eden. 'saving' the climate; 2) Presaging Apocalypse, fragility of nature, doomsday scenarios proliferate, generate fear by turning the 'volume up louder'; 3) Constructing Babel, man's control of Nature John Von Neumann, 1955; man's desire for control and mastery of the climate (with a subplot of geoengineering control). 4) Celebrating Jubilee (from Jewish Torah concept) environmental/social movement centered around climate change; demand for 'climate justice' and climate change becoming opportunity to bring about justice and equality (regardless of whether it is 'true' or not).
His conclusion that we cannot 'solve' climate change has some traction--he cites numerous inflection points (Kyoto, 2005, Stern Report, 2006, 4th IPCC 2007, Nobel Peace Prize for Al Gore, 2007) where it seemed that the alarm bells would be now sufficient to generate some grand solutions, To that list we can add two more IPCCs completed in 2014 and 2023, which now run to almost 2,500 pages (not including 'special reports), Likely almost no one reads them.
His conclusions on p. 333 are worth repeating but I won't bother. But he asserts that by sweeping all or most of the intractable problems of the world (unsustainable energy, endemic poverty, climatic hazards (i.e. weather), food security, structural adjustment, hyper-consumption, deforestation, biodiversity loss, etc.) under the single term 'climate change' we have created the 'Mother of all problems' such that it defies solution.
If Hulme set out to prove his title, he did a pretty good job! 4.5 stars, rounded down partly due to being a bit out of date.
