There are three major points that republicans should be made to address when they vie for elected offices. While they sit on their laurels, refusing to admit that the current climate change science is for real, challenge them with the fact that property & casualty insurance companies have been showing a tremendous increase in costs due to paying out more monies in claims due to extreme weather conditions.

The second point they need to address for “we the people,” is how will they assist us with the hidden tax of having to pay significantly more monies for auto and homeowners’ insurance policies.

Then because republicans do not like regulations, are they aware that they are okaying the harm to their constituents by avoiding the creation of state guidelines to enforce building codes designed to better protect homes from damages due to extreme weather fallout, like from hurricanes, tornadoes, storm surges, droughts, etc.

Here’s the rest of the story…

On September 13, 2017, Tyler Shalitis Actuarial Analyst for Pinnacle Actuarial Resources, Inc.,  penned the following report for Captive Insurance News, “Actuaries Adapt to Climate Change Using New Tools.”

“On August 28, 2017, the National Weather Service tweeted an infographic of the rainfall from Hurricane Harvey, followed by a troublesome statement: “So much rain has fallen, we’ve had to update the color charts on our graphics in order to effectively map it.” It is cause for concern that many indicators of climate change, such as extreme weather events, global temperature, and sea levels, continue to be on the rise.”

“Fortunately for the insurance industry, actuaries are also rising to the challenges posed by climate change. One recent example is the creation of the Actuaries Climate Index (ACI) and the forthcoming Actuaries Climate Risk Index (ACRI). These indexes were created jointly by the American Academy of Actuaries (AAA), Canadian Institute of Actuaries (CIA), Casualty Actuarial Society (CAS), and Society of Actuaries (SOA) to help actuaries address the challenges climate change has created.”

“These tools are necessary to respond to upward trends in weather-related losses. For instance, Munich Re has reported that since 1980, weather-related losses have increased nearly fourfold. The ability to quantify climate change is important, not just because of increasing losses but also because shifting climatic conditions could lead to unexpected types of losses like property damage in new regions.”

“Such unforeseen losses may, in turn, necessitate new products or the redefinition of current products in order to adapt. There are also growing concerns over which entities could be held liable for future climate change costs. Regulators will face challenges as well: Will there be sufficient solvency, liquidity, and capital in the marketplace to finance these new risks? Because of these and other issues, regulators will need to consider whether to require a statement of catastrophic or extreme weather risk by the enterprise risk manager, actuary, or risk modeler.”

“The ACI is one tool that has recently become available to actuaries. It uses a reference period of 1961 to 1990 for United States and Canadian climate data, which serves as a benchmark to evaluate how much the climate has shifted.”

“Six carefully selected climate variables are averaged together to create the ACI: high-temperature events, low-temperature events, heavy rainfall, drought, high wind, and sea level. The ACI can also be broken down by component or region to provide more specific information based on user preferences. The graph below shows the total ACI for the contiguous United States using monthly data from the beginning of 1961 to the summer of 2016. An overall increasing trend can be seen since the reference period, with a higher index representing an increased occurrence of extreme weather.”

“The ACRI is another index currently in development that is designed to relate loss data to climate data using regression analysis. The goal is to come up with a measure that quantifies historical climate risk. This historical ACRI can then be used to better predict the future risk and evaluate the impact of climate change. The ACRI is important for several reasons.”

The ACRI is also significant because using traditional methods to measure climate risk, such as trending historical data, are often inadequate. This is because, as illustrated in the above ACI chart, climate can move in a cyclical fashion, move erratically from year to year, and show trends. Since the ACRI is derived using regression, the resulting models can better anticipate these climate shifts.”

“The ACRI is further strengthened in that it is not only nationally aggregated but will be available by specific region, individual line of coverage, and even by specific hazard. For simplicity, the ACRI values are often mapped onto a value of 0 through 10, with 10 representing extreme climate risk, 5 indicating the same amount of climate risk on average when compared to the reference period, and 0 indicating virtually no risk.”

“The ACRI’s multiple applications include pricing or portfolio diversification. The pricing applications are more obvious, as the ACRI is better equipped to anticipate long-term trends and patterns in climate change risk versus more traditional methods. Incorporating the ACRI into pricing models can potentially aid insurers in setting more accurate rates, as well as in reducing climate change uncertainty loads in pricing and capital management environments.”

“The ACRI can also be highly useful for portfolio diversification purposes since it considers many components of climate risk. The ACRI evaluates the probability of a specific loss event such as a high-temperature event in a certain region, the amount of the exposures in that region, and how vulnerable those exposures are to a loss event (e.g., Texans are more likely better equipped to deal with a heat wave with resources such as air-conditioning, which Alaskans are less likely to possess). All of these ACRI features enable insurers to better quantify, diversify, and manage their risk.”

“Climate change signifies additional medium- to long-term uncertainty for the insurance industry. The ACI and ACRI are new resources that will enable actuaries to proactively deal with these future challenges. The ACI and ACRI can provide valuable insight into climate change and can be used in a variety of insurance applications like pricing and portfolio diversification. Actuaries cannot stop climate change, but they can keep doing what they have always done best—adapt and develop new methods to help the insurance industry continue to manage risk and thrive.”


  1. Gronda, well done. Did you share this with the actuary who was naysaying climate change. Quite simply, these actuarial organizations you write about are trying to assess increased risk due to climate change. The data has been building of the severity and is in keeping with predicted models of climate change models. Climate change impact is here now and for those who try to say “who are you going to believe, me or your own eyes?” need to open theirs.

    In the 2010 Mercer Investment Consulting study with the largest global pension scheme investment managers, they estimate the cost of doing nothing in the multiple tens of trillions of dollars. Marsh, one of the largest global risk management firms in the world, cites climate change risk as a significant risk in the world, with the World Economic Forum saying it is the second biggest risk, behind the global water crisis.

    These actuaries are doing their job and trying to assess the cost and risk. People are owed the truth about these risks. When leaders hide the truth, then people get hurt. And, for people who believe the President about statements downplaying climate change, they need to consider the Trump golf course development on the coast of Ireland formally requested the building of a sea wall to hold back the sea rise due to climate change. With his money at risk, Trump seeks help with climate change. As President, he denies the severity because the fossil fuel industry tells him to.

    Great post, Keith

    • Dear Keith,

      If I were in charge of democrats, I would have actuaries doing political ads regarding the anticipated increase in costs to the consumer because of climate change issues. I would have them visit various republican legislators. Once the consumer gets what the costs will be, they will be singing a different tune.

      Thanks for the added information as it is very helpful.

      Hugs, Gronda


  2. If global warming continues, Cat 5 hurricanes will be the norm due to warming of ocean waters. Hurricane Maria is on track to ravage the the already storm-weary Virgin Islands and Puerto Rico. I do see a direct cause and effect, why the Republicans can’t make this connection? Perhaps they have an allegiance to big oil, petrodollar, and to maintain the US dollar as world’s reserve currency, climate change be damned.

    Of course all money and wealth is meaningless if mother earth becomes uninhabitable. Food shortages will be inevitable and mass destruction/ flooding will become commonplace. World leaders are notorious for being short sighted, it’s up to we the ppl.


    • Dear !EarthUnited,

      I am watching Puerto Rico being ravaged. This is after Hurricane Irma. It really doesn’t matter what is causing these extreme weather events. We are going to have to mitigate for this new normal with infrastructure improvements, like with. better building codes to where structures can withstand strong winds and where any new buildings are built high above sea levels.

      Hugs, Gronda
