Risk aggravated by persistent extreme weather conditions – “Topics GEO” analyses 2014 natural catastrophes

Over the past years, persistent extreme weather conditions have triggered severe natural catastrophes and caused losses in the billion range. There is a growing number of scientific studies that suggest an increase in quasi-stationary weather patterns and their correlation with the considerable rise in temperature in the Arctic due to global warming.

The current “Topics Geo 2014” publication, with its in-depth analyses and vast trove of data on the natural catastrophes of the past year, addresses this topic.

“Persistent” weather patterns can develop in winter, when outbreaks of Arctic cold-air masses in mid-latitudes over several weeks can inflict high losses regionally. In summer, stationary high- or low-pressure systems can produce heat/drought or precipitation/flooding.

Such Weather patterns, some persisting for weeks, accounted for several weather-related natural catastrophes in 2014. These included the heavy winter snowfalls and ice in many regions of the USA incurring losses in the billions, and the windstorms and floods in Great Britain in February. The generally consistent pattern of the jet stream over the eastern Pacific, North America and North Atlantic produced the frosty winter in the USA, yet a very mild winter in Europe. In its wake, twelve major winter storms swept over Great Britain and Ireland from December 2013 to mid-February 2014, also causing severe flooding.

In North America, the cold winter caused overall losses in the vicinity of US$ 4bn and insured losses of US$ 2.3bn. Flooding in Great Britain incurred an overall loss of US$ 1.5bn, of which US$ 1.1bn was insured. The year's costliest natural catastrophe for the insurance sector, the snow storms in Japan (overall loss of US$ 5.9bn, insured losses of US$ 3.1bn) was also attributable to the altered atmospheric circulation patterns in the northern hemisphere described above.

“The persistent weather patterns are caused by uncommonly stationary waves of the jet stream, a band of strong, high-altitude winds, that separate the cold Arctic and warm subtropical air masses. “Troughs” and “ridges” of the jet stream bulging to the south or north, are responsible for events such as the long winter in North America in 2014. But persistent heavy rainfall or heatwaves in the summer months can also be traced back to the phenomenon”, according to Peter Höppe, Head of Geo Risks Research at Munich Re. The scientific community is engaging in intense discussion of whether climate change, and particularly the extremely pronounced warming in the Arctic, are responsible for these altered weather patterns. “It is not yet possible to produce causal proof, but there is a logical chain of indices”, Höppe stated.

New research sees the warming in the Arctic as an important factor in the increasing and persisting cold-air outbreaks towards the south, as over North America and Asia in 2014. A study of the Potsdam Institute for Climate Impact Research also establishes a correlation between weather extremes in summer with the accelerated melting of ice in the Arctic. Flooding in Europe (1997, 2002, 2013) or heatwaves in North America (1983,1984, 2011, 2012) merit mention here.

In addition to the longer-term trends and the natural catastrophes of 2014, Topics Geo 2014 also addresses the use of social networks for disaster relief and assessing losses from natural catastrophes. “If we can use information from social media more effectively, it will open up entirely new perspectives for crisis and catastrophe management. Faster and more precise loss estimates will become possible for the insurance industry, in future, if this information could be used even more systematically”, according to Torsten Jeworrek, Munich Re’s Reinsurance CEO.

In 2014, for the third year in a row, natural catastrophe losses remained below the long-term average. Overall losses from natural catastrophes totalled US$ 110bn, compared with average losses of US$ 190bn from the ten previous years. Insured losses came to about US$ 31bn (average loss, US$ 58bn). Although 7,700 people lost their lives in natural catastrophes, the number was significantly lower than average, roughly at the level last seen in 1984 (then around 7,000).

Jeworrek emphasised: “It would be wrong to conclude any trend reversal based on the last few years. The loss trend of the past decades is clearly upwards, primarily driven by the rise in exposed values.”

Munich Re stands for exceptional solution-based expertise, consistent risk management, financial stability and client proximity. This is how Munich Re creates value for clients, shareholders and staff. In the financial year 2013, the Group – which combines primary insurance and reinsurance under one roof – achieved a profit of €3.3bn on premium income of over €51bn. It operates in all lines of insurance, with almost 45,000 employees throughout the world. With premium income of around €28bn from reinsurance alone, it is one of the world’s leading reinsurers. Especially when clients require solutions for complex risks, Munich Re is a much sought-after risk carrier. Its primary insurance operations are concentrated mainly in the ERGO Insurance Group, one of the major insurance groups in Germany and Europe. ERGO is represented in over 30 countries worldwide and offers a comprehensive range of insurances, provision products and services. In 2013, ERGO posted premium income of €18bn. In international healthcare business, Munich Re pools its insurance and reinsurance operations, as well as related services, under the Munich Health brand. Munich Re’s global investments amounting to €209bn are managed by MEAG, which also makes its competence available to private and institutional investors outside the Group.
