A Users Guide to the Crisis of Civilization: And How to Save It
1. Climate Catastrophe
What is climate change? Is it a product of natural cyclical variations in the Earths
ecological systems, or is it a consequence of human activities? What are the implications of
climate change for the international system? How serious are the ramifications of climate
change for the continuity of modern industrial civilization? This chapter egins y
confronting the ma!or pulic"media deates regarding the causality of climate change,
reviewing the main arguments that challenge the idea that contemporary gloal warming is
due to fossil fuel emissions and therefore human"induced #anthropogenic$% The relevant
scientific literature is e&plored to discern whether we can e sure that climate change is
happening, and why%
I then e&plore the implications of climate change for national security, finding that a variety
of Western security agencies recognize that climate change will drastically alter the gloal
security landscape for the foreseeale future without significant preventive action% The focus
of this analysis is not to list the specific conflicts that might arise #an e&ercise performed
frequently elsewhere$,'ut to assess the overarching ramifications of gloal warming for the
ability of modern industrial civilization in its current form to survive% The analysis then
e&tends to a critical e&amination of the conventional narrative of the rate of gloal warming
as descried y the (nited )ations Intergovernment *anel on +limate +hange #I*++$, and as
generally endorsed y Western states% I argue that cutting"edge scientific research provides
compelling evidence that the current rate of gloal warming is far faster, and igger, than the
() models predicted% Integrating the impact of positive feedacs in the Earths climate
systems, suggests the proaility of a worst"case climate scenario well efore the end of the
-'stcentury . unless significant preventive and mitigating actions are taen%
/ut such actions must go far eyond the mere question of reducing emissions% Emissions
reductions have largely een addressed in a socio"political and economic vacuum, divorced
from the real"world systemic changes required to drastically reduce energy consumption in
general, and utilise cleaner and more energy"efficient technologies ased on renewale
energies in particular% 0et this inattention to the gloal systemic origins of the ecological

crisis is part of a long"term trend, evidenced y the fact that policymaers have largely
ignored several decades of dire warnings issued y the worlds leading climate and
environmental scientists% Therefore, for civilization to survive eyond the -' stcentury will
require fundamentalglobal systemic changeat the very heart of modern industrial social
relations% 1nly in the conte&t of such systemic change can the prospect of a post"caron
civilization that is no longer dependent on the unrelenting e&ploitation of hydrocaron
energies e realized%
1.1 A Debate Resolved? Current Climate Change is UnequivocallyAnthropogenic
The Scientific Consensus
Human"emissions generated climate change is perhaps the most prominent gloal crisis in
pulic consciousness . its e&istence is now readily acnowledged y most governments
including the (nited 2tates, even if reluctantly, and it is generally recognized that urgent
steps are required to prevent the prospect of mass e&tinction% What is missing from the
official discourse on climate, however, is not simply an acnowledgement of the real e&tent
and gravity of the civilizational catastrophe it poses, ut the corresponding measures required
to prevent or avert such catastrophe%

2ince '344 there has een an appro&imately 4%5 degree +elsius #+$ rise in gloal average
temperature #see 6igure '$% /ut as 6igure - depicts, this increase cannot e accounted for y
natural variations of solar and volcanic activity, nor y human"induced sulphate emissions,
which act to reduce gloal temperature% It is only y including the impact of human"induced
caron dio&ide #+1-$ emissions that climate models are ale to accurately simulate the rise in
gloal temperatures over the previous century of industrial civilization%

Industrial civilization derives almost all its energy from the urning of fossil fuels, pumping
caron dio&ide into the atmosphere . with the e&ception of appro&imately -"7 per cent from
renewale and nuclear sources% The emissions of primarily +1-. ut also nitrous o&ide,
methane, chlorofluorocarons, among other greenhouse gases . from the industries that drive
our economies and sustain our infrastructures, are the main engine of gloal warming in the
last few decades% This does not mean that all climate change is solely due to human"induced
+1-emissions% 2cientists acnowledge that there are many other factors involved in climate
change, such as solar activity, as well as periodic changes in the Earths orit% 0et they have
overwhelmingly confirmed that these are not the primary factors currently driving gloal
warming%
8loal warming septics often point to the fact that human"induced +1-emissions are tiny
compared to natural emissions from ocean and vegetation% What they forget, however, is that
natural emissions are alanced y natural asorptions y ocean and vegetation% This natural
alance has ecome increasingly unstale due to additional +1-emissions from human
industrial activities% In terms of natural emissions, consumption of vegetation y animals and
microes accounts for aout --4 gigatonnes of +1-per year% 9espiration y vegetation emits
around --4 8igatonnes #8t$% The ocean releases aout 774 8t% This totals to aout 554 8t of
natural emissions% In terms of natural absorptions, land plants asor aout ::4 8t of caron
per year and the ocean asors aout 774 8t, again roughly totaling at aout 554 8t% This
emission"asorption parity #554 8t released and 554 asored$ ensures that natural
atmospheric +1-levels remain in overall alance even as emissions and asorptions fluctuate
over time% In comparison human emissions are only around -;%: 8t per year% The prolem is
that this seemingly small addition of +1 -into the atmosphere y industrialization cannot beabsorbed by the planet% 1nly aout :4 per cent is actually asored, largely y oceans,
leaving ;4 per cent in the atmosphere% Worse still, the oceans are increasingly losing their
aility to asor +1-, with the 2outhern 1cean and )orth

The ma!ority of scientific studies show that climate sensitivity to +1 -emissions is high, or
in other words that +1-emissions induce large increases in gloal temperature% espite the
media images of a raging deate among climate scientists, the fundamentals are agreed on .
the direct connection etween +1-and gloal temperatures has een empirically oserved y
analysis of ice cores, paleoclimate records, oservations of ocean heat uptae, and
temperature responses to the solar cycle, among other data% The empirically"focused studies
including pulished research from the '334s to -443, show that douled +1 -emissions
would contriute to warming at least within the range of '%: to : degrees +% 7
The origins of current climate change are therefore no longer a matter of serious scientific
deate% The landmar declaration came in -445, when the (nited )ations Intergovernmental
*anel on +limate +hange #I*++$ pulished its 6ourth
It is therefore important to recognize that claims y septics that there is no scientific
consensus on climate change are deeply misleading% The scientific consensus can e
discerned not only from the I*++, ut from other meta"analyses of the peer"reviewed
literature% In -44:, (2 geoscientist )aomi 1reses, *rofessor of History and 2cience 2tudies
at the (niversity of +alifornia, 2an iego, conducted a survey of the 3-C peer"reviewed
scientific papers on gloal climate change from '337 to -447% 2he found that 5> per cent
e&plicitly or implicitly accepted the consensus view, while -> per cent too no position and
dealt purely with methods or paleoclimateF

@9emaraly, none of the papers disagreed with the consensus position%%% Dany detailsaout climate interactions are not well understood, and there are ample grounds forcontinued research to provide a etter asis for understanding climate dynamics% Thequestion of what to do aout climate change is also still open% /ut there is a scientificconsensus on the reality of anthropogenic climate change% +limate scientists have
repeatedly tried to mae this clear% It is time for the rest of us to listen%A ;
Efforts to disprove the e&istence of this scientific consensus remain poor% 6or instance,
although social anthropologist /enny *eisner attempted to refute 1reses findings in his
own survey of the same peer"reviewed papers, he managed to flag"up only 7: studies which
he claimed raised douts aout anthropogenic gloal warming% This is a tiny fraction . only

@=ones is taling aout how scientists compare temperature data from thermometers withtemperature data derived from tree rings% +omparing that data allows scientists to derive
past temperature data for several centuries efore accurate thermometer measurementswere availale% The gloal average surface temperature since 'CC4 is ased onthermometer and satellite temperature measurements%%%
In some parts of the world, tree rings are a good sustitute for temperature record% Treesform a ring of new growth every growing season% 8enerally, warmer temperatures producethicer tree rings, while colder temperatures produce thinner ones% 1ther factors, such as
precipitation, soil properties, and the trees age also can affect tree ring growth%The Btric, which was used in a paper pulished in '33C in the science !ournal )ature, is
to comine the older tree ring data with thermometer data% +omining the two data setscan e difficult, and scientists are always interested in new ways to mae temperaturerecords more accurate%
Tree rings are a largely consistent source of data for the past -,444 years% /ut since the'3;4s, scientists have noticed there are a handful of tree species in certain areas thatappear to indicate temperatures that are warmer or colder than we actually now they are
from direct thermometer measurement at weather stations%BHiding the decline in this email refers to omitting data from some 2ierian trees after
'3;4% This omission was openly discussed in the latest climate science update in -445from the I*++, so it is not Bhidden at all%
Why 2ierian trees? In the 0amal region of 2ieria, there is a small set of trees withrings that are thinner than e&pected after '3;4 when compared with actual thermometermeasurements there% 2cientists are still trying to figure out why these trees are outliers%2ome analyses have left out the data from these trees after '3;4 and have usedthermometer temperatures instead% Techniques lie this help scientists reconstruct pastclimate temperature records ased on the est availale data%A

Thus, (+2 rightly concluded that whoever stole the emails @could only produce a handful
of messages that, when taen out of conte&t, might seem suspicious to people who are not
familiar with the intimate details of climate science%A --
The conclusion is simpleF claims that gloal warming is not happening, or if happening has
nothing or little to do with human activities, fall outside the e&isting scientific consensus, and
often come from people with vested political or economic interests, for whom the study of
climate is outside their professional qualifications and field of e&pertise% The Bseptic
strategy is simpleF to misquote, quote of conte&t, andMor misrepresent the statements and
findings of real climate scientists% 0et despite their lac of crediility, these claims and the
ad science they rest on, frequently receive widespread media coverage% /efore e&amining
the impacts of climate change, I critically review some of the most prominent Bseptical
approaches to anthropogenic climate change which try to deny the role of human activities,
finding them to e deeply unscientific%
Solar Activity and Climate Variation
1ne of the most common misconceptions cited y Bman"made climate septics #hereafter
referred to simply as Bclimate septics or Bseptics$ is that the 2un is the primary cause ofcontemporary gloal warming% The Earths climate history does evince a close correlation
etween solar activity and gloal temperature change% 4 years% The scientists argue that @long"term climate variations are
affected y solar magnetic activity%A 0et the same study points out that the correlation
etween solar activity and temperature ceased in 195, after which gloal average
temperatures escalated despite solar activity remaining stationaryF @)ote that the most recent
warming, since around '35>, has een considered in the aove correlations% uring these last
74 years the solar total irradiance, solar (N irradiance and cosmic ray flu& has not shown any
significant secular trend, so that at least this most recent warming episode must have another
source%A-7
2imilar conclusions have een reiterated independently throughout the scientific literature%
Dore recently in -44C, a study pulished yNaturenoted that @the level of solar activity
8/12/2019 Climate Change Chapter 1 a Users Guide to the Crisis of Civilization by Ahmed1
10/52
during the past 54 years is e&ceptionalA and @may indicate that the 2un has contriuted to the
unusual climate change during the twentieth century%A 0et it goes on to confirm that @solar
variaility is unliely to e the prime cause of the strong warming during the last three
decades%%% even under the e&treme assumption that the 2un was responsile for all the gloal
warming prior to '354, at the most 74 per cent of the strong warming since then can e of
solar origin%A-:

Oined to this misconception is the claim that gloal warming has stoppedsince 199#% The
argument is that due to the lapse in sunspot activity as well as cyclical variations of gloal
warming and cooling, the coming decades will constitute a period of prolonged global
cooling#also see ne&t su"chapter$% > to P'355 #cool cycle$, then retreated rapidly from P'355 to the
present #warm cycle$%A This correlates with the period of gloal warming which therefore
appears to e an outcome of such oscillations% @If the trend continues, the current warm cycle
should end soon,A and gloal warming will e over for another -> years%-5/y implication,
gloal warming is nothing to worry aoutK In the ne&t section, we loo at this question . did
gloal warming stop in '33C #or -44'$ . in more detail, ut efore that, it is important to
understand the deeper misconceptions underlying Easterroos approach%
6irstly, he proffers a rather eccentric argument, indeed, a lone voice in the scientific
community, with no wider corrooration in the relevant peer"reviewed literature% 2econdly,
his paper itself was not peer"reviewed and remains unpulished in any recognized relevant
physical science !ournal% These prolems should oviously raise our initial suspicions%
Thirdly, further e&amination of one of Easterroos own e&les, the *acific ecadal
1scillation #*1$ vindicates them% , the *1
switched to a warm phase as gloal warming egan% In '3:;, the *1 switched to a cool
phase as temperatures cooled mid"century% In '355, the *1 switched to a warm phase
around the same time as the modern gloal warming period% These correlations, for
Easterrooe, prove that gloal warming is nothing more than the function of natural
oscillations in the Earths climate that will inevitaly give way to gloal cooling, efore
giving rise to another cycle of warming%

However, as 6igure 7 shows, while the *1 does have some degree of correlation with
short term variations in gloal temperature, this is star$ly outweighed by the contrast% While
the *1 oscillates etween positive and negative values roughly along the same level, global
average temperatures in the same period display an unambiguous long%term warming trend%-C
To account for gloal temperature increases since the dawn of the twentieth century requires
totalling the impact from all relevant forcings including solar, aerosols, +1 -emissions, and
so on% /y itself, the *1 does not provide an adequate e&planation for gloal warming%

+oncerns over the national security implications of climate change were also aired in
Europe% In early -44C, a high"level European (nion #E($ report to -5 heads of governments
warned of the proaility of @significant potential conflictsA in coming decades due to
@intensified competition over access to, and control over, energy resources%A Written y
=avier 2olana, the E(s foreign policy chief, and /enito 6errero"Waldner, the E(
commissioner for e&ternal relations, the report argued that gloal warming would precipitate
ma!or security issues for Europe, such as mass migrations, failed states and political
radicalization% In particular, it noted that the quicened thawing of the

9apid climate change, leading to catastrophic droughts, famines and rioting, would thus
effect mounting national and international tensions, mediated through defensive and offensive
strategies that could escalate into a terrifying arc of gloal conflicts, oriented around deadly
competition over control of increasingly scarce resourcesF @)ations with the resources to do
