(also known as “cash-flow underwriting”). As occurredafter the European windstorms of 1999 (ABI 2004),insurers encounter liquidity problems when paying losses,forcing the sale of large blocks of securities,which, in turn, creates undesirable “knock-on” impactsin the broader financial markets. Outcomes are particularlybad in years when large catastrophe losses coincidewith financial market downturns.Most significantly impacted are insurance operations inthe developing world <strong>and</strong> economies in transition (theprimary growth markets for insurance — see figure3.4), already generating nearly US $400 billion/yearin premiums. This arises from a combination of inferiordisaster preparedness <strong>and</strong> recovery capacity, morevulnerable infrastructure due to the lack or non-enforcementof building codes, high dependency on coastal<strong>and</strong> agricultural <strong>economic</strong> activities, <strong>and</strong> a shortage offunds to invest in disaster-resilient adaptation projects(Mills 2004). Insurers from industrialized countriesincreasingly share these losses via their growingexpansion into these emerging markets.In the face of the aforementioned trends, insurers usetraditional methods to reduce their exposures:increased premiums <strong>and</strong> deductibles, lowered limits,non-renewals, <strong>and</strong> new exclusions.

100 | FINANCIAL IMPLICATIONSdem<strong>and</strong> for insurance increases at first, it evolves intoreduced willingness to pay <strong>and</strong> some shift from the useof insurance to alternatives such as weather derivatives.As warned by the US Government AccountabilityOffice (GAO 2005), private insurers encounterincreasing difficulty in h<strong>and</strong>ling extreme weatherevents. As commercial insurability declines, dem<strong>and</strong>semerge to exp<strong>and</strong> existing government-provided insurancefor flood <strong>and</strong> crop loss, <strong>and</strong> to assume new risks(for example, for wildfires <strong>and</strong> windstorms). Cashstrappedgovernments, however, find that claims interferewith balancing their budgets (Changnon 2003)<strong>and</strong>, in turn, limit their coverage, with the result thatmore ultimate losses are shifted back to the individuals<strong>and</strong> businesses impacted by climate <strong>change</strong>.Compounding the problem, international aid for naturaldisasters continues its current decline as a percentageof donor country GDP (Mills 2004).<strong>Climate</strong> <strong>change</strong> accelerates several forms of unrelatedadverse structural <strong>change</strong> already underway in theinsurance industry. 6 This manifests as a rise in competitionamong insurers, significant consolidation due tothe reduced viability of small firms, increased riskexposure via globalization <strong>and</strong> a growing proportionof competing self-insurance <strong>and</strong> alternative risk transfermechanisms.CCF-II: SURPRISE IMPACTSA shift from gradual to non-linear impacts of climate<strong>change</strong> serves to intensify the adverse effects of CCF-I.Disruptions are greater <strong>and</strong> the <strong>economic</strong> cost of naturalcatastrophes rises at an increasing rate, with elevatedstress on insurers <strong>and</strong> reinsurers. This scenario isalso fundamentally different for insurers insofar asCCF-I entails relatively predictable <strong>change</strong>s that can(to a degree) be adjusted to, whereas CCF-II involvesa substantial increase in impacts <strong>and</strong> uncertainty, significantchallenges to the actuarial processes thatunderpin the insurance business.Life <strong>and</strong> <strong>health</strong> impacts are particularly amplified incomparison to the outcomes in CCF-I. Extreme heatcatastrophes become more common. Events on a parwith that seen in Europe in the summer of 2003 cometo the US with the result that offensive air masses ofunprecedented length range from almost 200% to over400% above average. Intensities also exceed thehottest summers over the past 60 years by a significantmargin. All-time records for maximum <strong>and</strong> high minimumtemperature are broken in large numbers of cities,with corresponding death rates five times that previouslyseen in typical summers. Aside from mortalities, hospitalizationstax hospital resources in emergencyroom(s) already hit hard by constrained budgets.Also due, in part, to temperature increases, the currenttrend towards increasingly damaging wildfires continues.Both a cause <strong>and</strong> impact of climate <strong>change</strong>,more fires set intentionally to clear forests <strong>and</strong> creategrazing l<strong>and</strong> in the developing world grow out of control(due to climate-<strong>change</strong> droughts <strong>and</strong> high winds).Such associated events caused an estimated US $9.3billion in <strong>economic</strong> damages in 1997 (CNN 2005).Another bad year in 2005 forced the closures ofKuala Lumpur’s largest harbor <strong>and</strong> most other businesses<strong>and</strong> manufacturing plants, as well as disruption totourism. A continuation of the trend results in a combinationof insured losses, with causes ranging from anupturn in respiratory disease to widespread businessinterruptions. Included in the impacts are well-insuredoffshore industries, based in industrialized countries.The combination of more aeroallergens, rising temperatures,greater humidity, more wildfire smoke, <strong>and</strong>more dust <strong>and</strong> particulates considerably exacerbatesupper respiratory disease (rhinitis, conjunctivitis, sinusitis),lower respiratory disease <strong>and</strong> cardiovasculardisease. Cases of asthma increase sharply. A 30%increase in cases would occur, raising the total toabout 400 million new cases per year by 2025.The baseline cost was US $13 billion/year in the USalone as of the mid-1990s (half of which are direct<strong>health</strong> care costs). If a 30% increase took place in theUS, the incremental cost of US $4 billion/year wouldbe on a par with that of a very large hurricane eachyear.With a continued rise in atmospheric CO2 concentrations<strong>and</strong> early arrival of spring, a significant jump inwinter <strong>and</strong> summer warming (for example, from acceleratedrelease of methane), is accompanied by a stepwiseadvance in the hydrological cycle, <strong>and</strong> ensuinggrowth of weeds, pollen <strong>and</strong> molds. Additionally, dust6Even in wealthy nations, governments are increasingly seeking to limit their financial exposures to natural disasters. As a case in point, therisk of residential flooding in the US is deemed largely uninsurable, which has given rise to a National Flood Insurance Program (NFIP), withmore than 4.2 million policies in force, representing nearly US $560 billion in coverage. The NFIP pays no more than US $250,000 perloss per household <strong>and</strong> US $500,000 for small businesses.
