Insurance Information Institute (I.I.I.) chief actuary James Lynch on an innovative actuarial approach.
It was a record-breaking rainy day in Colorado Springs when I attended a panel last month describing a new climate index the actuarial community is introducing.
The 1.58 inches of rain that fell May 19 almost doubled the previous record for that day. The Actuaries Climate Index (ACI)–a joint effort between the Casualty Actuarial Society (CAS), the American Academy of Actuaries, the Canadian Institute of Actuaries, and the Society of Actuaries–is intended to monitor how often extreme events – blistering heat, shivering cold, record winds and rain – strike 12 regions in North America.
It addresses an interesting conundrum about insurance and climate change. Given that the climate is changing – though quite a few in the industry dispute that – how can insurance incorporate the change into pricing?
The ACI, which will be introduced later this year, tries to address that. It will measure how many severe events occur every quarter. Since catastrophes are an important component of claim costs, changes in the long-term trend can affect insurance prices.
As I wrote for the CAS:
The index is an educational tool that could help pricing actuaries incorporate long-term trends into their mathematical models; it could also help actuaries and others working in enterprise risk management by quantifying the risk in a subtle, long-term trend.”
Insurance prices are famously based on historical data, trended forward. The index would help show whether extreme events are becoming more or less common, and actuaries could trend this information forward to set rates.
Actuaries have been working on the index for a couple of years. Historical data has shown that over the past few years, the frequency of extremely hot days has increased, while the frequency of extremely cold days has decreased. The overall ACI climbed from the 1990s on, though it appears to have leveled off in recent years.
In its Facts and Statistics section, the I.I.I. gives comprehensive snapshots about catastrophes, both in the United States and worldwide.

I.I.I. chief actuary Jim Lynch offers his perspective on how insurers are responding to climate change:
The insurance industry got a report card this week on a test I’m not sure they knew they were taking. And the grading curve was, in my opinion, harsh.
Ceres, a nonprofit group that promotes sustainable business practices, rated 330 insurers – life, health and property/casualty – on how well they are responding to climate change.
Before I wade further into the topic, it is important to acknowledge that insurance companies and their managers have a range of opinions on global warming that is as wide as the opinions of Americans overall on the topic. There is no insurance industry position, though there are individuals and companies with strong opinions – just as with all Americans.
On a four-point scale, nine companies got the highest mark (“leading”): Ace, Munich Re, Swiss Re, Allianz, Prudential, XL Group, The Hartford Financial Services Group, Sompo Japan and Zurich. Matthew Sturdevant of the Hartford Courant does a nice job rounding up how these firms earned their grade.
Ceres gave “minimal” or “beginning” rankings to 276 insurers, 84 percent on my calculator. The New York Times played up that aspect. But the analysis may be skewed because of the source of the rankings and how Ceres adapted that source.
Ceres took a National Association of Insurance Commissioners (NAIC) survey that six states require on climate change. The survey consists of eight yes-or-no questions, each of which follows up with why the insurer answered as it did. The follow-up questions are open-ended – companies can respond with as little or as much information as they like.
The questions help regulators when they assess a company’s enterprise risk management, specifically how hard a company looks for potential problems that might not hit them until years from now. Climate change certainly has that potential.
Ceres took those answers and graded them on its own criteria, resulting in six scores from 1 to 4, which it then re-summarized into a single grade.
Boiling a complex set of open-ended answers is tricky enough, but Ceres has, in my opinion, misused the NAIC survey, which is supposed to help regulators understand how well insurers are considering climate change in their risk management, not whether insurers are acting as stewards of the environment.
So it doesn’t seem like Ceres is giving a fair test. Insurers are answering questions on how climate change might affect their business then being rated on how their actions will reduce carbon emissions. It’s like being told to write an essay, then being graded on penmanship.
How could this skew results? Some insurers are minimally exposed to climate change, so it would not be prudent risk management for them to devote valuable resources to the issue. Medical malpractice writers are an obvious example. Climate change might be important to the world at large, but how relevant is it to the operation of a medical malpractice writer?
Property insurers are in a different boat, pardon the irresistible pun. Rising sea levels and growing weather extremes are important developments, and it would seem a prudent coastal writer would consider whether those trends will continue, abate or accelerate. A company that writes worldwide has still more to think about, as climate trends would affect other countries more than our own.
Seen that way, it makes perfect sense that some large, multinational insurers are concerned about climate change while small writers not exposed to property insurance are less so.
On the life/health side, there is a signal-to-noise problem. Climate change appears to have an impact on mortality, but it’s really small. A 2011 Brookings study suggested that climate change will increase U.S. age adjusted mortality rates by about 3 percent over the next 85 years or so. That rate has declined by 1 percent per year over the past 35 years. So the impact of climate change on mortality is likely to be overwhelmed by other forces at work.
That’s not to say that life expectancies outside the U.S. won’t be affected more. But a life insurer that only writes U.S. risks might not want to incorporate climate change-induced mortality changes from, say, Australia, into its business model.
Regardless, life insurers have a built-in mortality hedge in pairing annuity sales with life insurance. People who die sooner drive life insurance profits lower. But they push annuity profits higher, and vice versa. Combine that with the small impact of climate change on U.S. mortality and it makes perfect sense that a great many U.S. life insurers have decided that climate change doesn’t form a central part of their risk management strategy.
Health insurers are in a similar situation. Gradual changes in health have small effects on their business, and those changes can be easily adjusted to year by year. Pandemics are a bigger risk, so risk management efforts focus there.
That helps explain why health and life insurers didn’t score as high as property/casualty insurers. They have less at stake.
California’s insurance department doesn’t sound too concerned. Ceres relied on CA DOI information to compile its report, so there’s a good chance the Ceres researchers saw a 2013 press release that said this:
The results of this year’s survey are a positive sign for the insurance industry and the environment,” said Commissioner Jones. “It is encouraging to see that insurers are aware of the risks that a changing climate brings, and moreover they are taking steps to ensure their responses to these risks are sufficient to protect their business.”
More than 1,000 companies [Duplicates and multi-company insurance groups account for the difference between Ceres’ total and California’s.] were required to respond to the survey. The survey revealed that roughly 75 percent of insurers have a plan for identifying climate change-related risks that could affect their business, and are taking actions to mitigate these risks. Responses to the eight survey questions reveal that nearly every insurer is aware of the risks posed by a changing climate, and an overwhelming majority of insurers have incorporated mitigating practices into their business model.”
That sounds like an industry that is handling the issue prudently, even if it is not the way an environmental group would prefer.

As world leaders gather to discuss climate change at the United Nations this week, a new report from the Global Reinsurance Forum (GRF) says risk prevention and mitigation measures as well as risk transfer are the key to managing this threat.
According to the report, up to 65 percent of climate risks can be averted by adaptation measures including infrastructure development, technology advancements, shifts in systems and behaviors such as improved building codes and land use management, and financial measures.
The global re/insurance industry plays a vital role in planning and implementation of such measures. As the GRF says:
Future insurability will depend on well-planned adaptation: without it, property insurance will become less affordable and less accessible.
The world cannot simply insure its way out of the effects of climate change, but adaptation allows the global burden of potential loss to be reduced and shared, helping to keep the most vulnerable from being overwhelmed.”
The report points out that the reinsurance industry is particularly exposed to the impact of climate change given its role as an ultimate destination of risk:
The industry identified climate change as an emerging risk more than twenty years ago; it has since become a key component of every company’s long-term risk management strategy.”
Citing a 2012 IPCC report, the GRF notes that extreme weather events, such as storms, floods, droughts, heat waves as well as rising sea levels, crop failures and water shortages have become more numerous and severe.
Reinsurers can make an important contribution by developing protection and mitigation-finance solutions to address the specific challenges that climate change presents.
At the same time, the GRF says reinsurers are advancing understanding of climate change-related risk through the development of natural catastrophe models and via collaboration with universities and scientific institutions. They are also monitoring relevant phenomena such as urbanization, population concentration, property and commercial activity in high-risk areas along the coasts and flood plains.

An article in The New York Times over the weekend gave a frightening account of the ongoing severe drought across California that is now threatening the stateâ€™s water supply.
As farmers, ranchers and homeowners brace for what could be the stateâ€™s worst drought in 500 years, The NYT reports that the snowpack in the Sierra Nevada, which supplies much of California with water during the dry season, was at just 12 percent of normal last week, reflecting the lack of rain or snow in December and January.
The NYT quotes Tim Quinn, executive director of the Association of California Water Agencies, saying:
We are talking historical drought conditions, no supplies of water in many parts of the state. My industryâ€™s job is to try to make sure that these kind of things never happen. And they are happening.â€
The latest U.S. Drought Monitor, published last Thursday, put 9 percent of the state of California into â€œExceptional Droughtâ€ â€“ the worst possible category of drought. According to Dr. Jeff Mastersâ€™ WunderBlog this is the first time since the Drought Monitor product began in 2000 that a portion of California was put into â€œExceptional Drought.â€
Meanwhile, parts of the state experiencing â€œExtreme Drought,â€ the second worst category of drought, increased to 67 percent.
The U.S. Drought Monitor notes that a few of the impacts within the â€œExceptional Droughtâ€ areas include fallowing of land, wells running dry, municipalities considering drilling deeper wells, and little to no rangeland grasses for cattle to graze on, prompting significant livestock sell off.
Over at Slate.com Eric Holthaus says that puts the current California drought on par with recent major droughts in Texas (2010-11) and the Midwest (2012), both of which were multibillion-dollar disasters.
For insurers, droughts can be costly too. According to analysis by Munich Re, drought in various parts of the U.S. in 2012 caused $15 billion to $17 billion in insured losses, making it the second costliest disaster after Hurricane Sandy.

Climate change is among the five most likely and most potentially impactful global risks, according to the just-released World Economic Forum (WEF) 2014 Global Risks Report.
The report assesses 31 risks that are global in nature and have the potential to cause significant negative impact across entire countries and industries if they take place.
An analysis of the five risks considered most likely and most impactful since 2007 shows that environmental risks, such as climate change, extreme weather events and water scarcity, have become more prominent since 2011 (see chart above).
This suggests a pressing need for better public information about the potential consequences of environmental threats, the WEF says.
Concern about socio-economic risks such as income disparity, unemployment and fiscal crises has become more prominent over the years.
The report reveals that fiscal crises and structural unemployment and underemployment are among the most impactful risks while the latter also feature among those most likely to occur. This has knock-on effects on income disparities, which is regarded as the overall most likely risk, the WEF notes.
Cyber attacks and the breakdown of critical information infrastructure also feature among the most prominent risks in this yearâ€™s report.
The WEF notes:
This arguably reflects the increasing digitization of economies and societies, where rising dependence on information and data, as well as the systems to analyze and use them, has made attacks more likely and their effects more impactful.â€
WEF note: Global risks may not be strictly comparable across years, as definitions and the set of global risks have been revised with new issues having emerged on the 10-year horizon. For example, cyber attacks, income disparity and unemployment entered the set of global risks in 2012. Some global risks were reclassified: water supply crises and income disparity were reclassified as environmental and societal risks, respectively, in 2014.
The report is published in collaboration with Marsh & McLennan Companies, Swiss Re, Zurich Insurance Group, National University of Singapore, Oxford Martin School, University of Oxford, Wharton Risk Management and Decision Processes Center, University of Pennsylvania.

With two months to go to the one-year anniversary of Hurricane Sandy, a federal task force created after the storm has issued a report thatâ€™s getting a lot of media coverage.
The plan includes 69 policy initiatives, of which a major recommendation is to build stronger buildings to better withstand future extreme storms amid a changing climate.
Shaun Donovan, secretary of the U.S. Department of Housing and Urban Development, and chair of the task force, notes:
Last year alone, there were 11 different weather and climate disaster events across the United States with estimated losses exceeding $1 billion each. We know that every dollar we spend today on hazard mitigation saves us at least $4 in avoided costs if a disaster strikes again. By building more resilient regions, we can save billions in taxpayer dollars.â€
The report makes clear that rebuilding to outdated standards is no longer an option given the impact of climate change and rising sea levels:
No single solution or set of actions can anticipate every threat, but decision makers at all levels must recognize that climate change and the resulting increase in risks from extreme weather have eliminated the option of simply building back to outdated standards and expecting better outcomes after the next extreme event. There is clear evidence at the national level that investments made to mitigate risk have achieved significant benefits.â€
One section of the plan focuses on addressing insurance challenges, understanding and affordability.
Specifically, the taskforce recommends: streamlining payouts to policyholders in the wake of disaster; improving policyholder awareness of factors that affect flood risk and insurance rating decisions; and studying affordability challenges of flood insurance as the National Flood Insurance Program (NFIP) transitions toward full risk rates.

We start the week with a new animation from NASA that shows the increasing risk of wildfire activity across the United States in the coming decades.
An article on the NASAÂ website notes that with satellite and climate data, scientists have been able to track an increase in dry conditions since the 1980s.
Climate projections suggest this trend will continue, increasing the risk of fire in the Great Plains and Upper Midwest by the end of the 21st Century, according to NASA.
The newest generation of climate models project drier conditions that likely will cause increased fire activity across the United States in coming decades. These changes are likely to come in a number of different forms, including longer fire seasons, larger areas at risk of wildfire, and an increase in the frequency of extreme events â€“ years like 2012 in the western United States.â€
Fire seasons are starting earlier due to warmer spring temperatures and earlier snowmelt, and they are lasting longer into the fall, NASA notes.
It cites NIFC statistics indicating that 100,000-acre wildfires are becoming increasingly frequent.
Here’s the animation:

As we basked in 70 degree temperatures in parts of the Northeast on Sunday, just a few days in the wake of a norâ€™easter and nearly two weeks after Hurricane Sandy, itâ€™s understandable that the topic of climate change is trending online.
In a post over at the Wall Street Journalâ€™s Metropolis blog, Eric Holthaus asks the direct question: did climate change factor into recent storms?
He cites the connection between long-term sea level rise and the enhanced coastal flooding that devastated parts of Greater New York as evidence of a much clearer link between Sandy and climate change.
New York Harborâ€™s average water level is now 12 to 18 inches higher than it was in the 1880s, Holthaus says, and scientists estimate about 8 to 12 inches of that is a direct result of global warming. So, more people were affected in the tri-state during Hurricane Sandy than would have been if the same storm had struck in a world without climate change.
For the victims of Hurricane Sandy, it may come as little consolation, but history may show them to beâ€”with absolute certaintyâ€”among the first people in the United States directly affected by climate change.”
In another post over at Scientific Americanâ€™s Observations blog, Mark Fischetti writes that scientists, journalists and even insurers are starting to drop the caveats, and simply say that climate change is causing big storms.
Fischetti suggests that as scientists collect more and more data over time, more of them will be willing to make the same data-based statements.
A recent study by Munich Re reported that North America was most affected by the rising number of natural catastrophes. Specifically, it noted a nearly five-fold increase in the number of weather related loss events in North America for the past 30 years, compared with an increase of 4 in Asia, 2.5 in Africa, 2 in Europe and 1.5 in South America.
In a press release announcing the study, Munich Re said:
Climate change particularly affects formation of heat-waves, droughts, intense precipitation events, and in the long run more probably also tropical cyclone intensity. The view that weather extremes are becoming more frequent and intense in various regions due to global warming is in keeping with current scientific findingsâ€¦â€
Munich ReÂ added:
Up to now, however, the increasing losses caused by weather related natural catastrophes have been primarily driven by socio-economic factors, such as population growth, urban sprawl and increasing wealth.â€

A new study by NOAA and UK Met Office scientists makes the link between global warming and extreme weather events.
The paper, Explaining Extreme Events of 2011 from a Climate Perspective, looks at six global extreme weather and climate events from 2011, including last yearâ€™s drought in Texas.
Key takeaways from the paper are:
– Determining the causes of extreme events remains difficult. While scientists cannot trace specific events to climate change with absolute certainty, new and continued research help scientists understand how the probability of extreme events change in response to global warming.
– La NiÃ±a-related heat waves, like that experienced in Texas in 2011, are now 20 times more likely to occur during La NiÃ±a years today than La NiÃ±a years fifty years ago.
– The UK experienced a very warm November 2011 and a very cold December 2010. In analyzing these two very different events, UK scientists uncovered interesting changes in the odds. Cold Decembers are now half as likely to occur now versus fifty years ago, whereas warm Novembers are now 62 times more likely.
– Climate change cannot be shown to have played any role in the 2011 floods on the Chao Phraya River that flooded Bangkok, Thailand. Although the flooding was unprecedented, the amount of rain that fell in the river â€œcatchmentâ€ area was not very unusual. Other factors, such as changes in reservoir policies and increased construction on the flood plain, were found most relevant in setting the scale of the disaster.
TheÂ New York Times has more on the study findings.
Release of the study comes along with NOAAâ€™s 2011 State of the Climate report which found that worldwide 2011 was the coolest year on record since 2008, yet temperatures remained above the
30 year average.
NOAAâ€™s climate report also provides details on a number of global extreme events from last year, including the Thailand floods, drought and tornado outbreaks in the U.S., floods in Brazil and the summer heat wave in central and southern Europe.
In the words of Deputy NOAA Administrator Kathryn Sullivan:
2011 will be remembered as a year of extreme events, both in the United States and around the world. Every weather event that happens now takes place in the context of a changing global environment. This annual report provides scientists and citizens alike with an analysis of what has happened so we can all prepare for what is to come.â€

As wildfires continue to burn in Colorado, New Mexico, Utah, Wyoming and Arizona, we read that U.S. Forest Service chief Tom Tidwell is renewing his call to restore forests to a more natural state in which fire was part of the landscape.
The Associated Press reports that the Forest Serviceâ€™s plan is to set the clock back to zero, accelerating restoration programs â€“ including prescribed fires and mechanical thinning â€“ by 20 percent each year in key areas that are facing the greatest danger of a catastrophic fire.
According to AP, four million acres are being targeted this year with a $1 billion budget.
Meanwhile, a new report from scientists at the University of California at Berkeley and Texas Tech University says that climate change will cause more wildfires across North America and Europe in the next 30 years.
The study used 16 different climate models to generate its results. Risk Management Monitor has more on its findings.
And a new climate analysis from NOAA notes that the U.S. experienced its hottest spring (March-May) on record, with an average temperature of 57.1Â°F, 5.2Â°F aboveÂ the 1901-2000 long-term average, surpassing the previous warmest spring (1910) by 2.0Â°F.
With the warmest March, third warmest April and second warmest May, Spring 2012 marked the largest temperature departure from average of any season on record for the contiguous United States, NOAA says.
In May, ongoing drought, combined with windy conditions, created ideal wildfire conditions across the Southwest.
NOAA notes that the Whitewater-Baldy Fire complex in the Gila National Forest of western New Mexico had charred over 210,000 acres by the beginning of June, surpassing 2011â€™s Las Conchas Fire as the largest wildfire on record for the state. The Whitewater-BaldyÂ fire is still burning.
