According to the study recently released by German reinsurer, insured losses, at around USD 27 billion, were higher than usual (USD 20 billion) due to the large proportion of weather disaster losses in North America.
North America accounted for 47% of overall losses and for 82% of insured losses, significantly more than the respective long-term averages (35% and 60%). In contrast, natural disasters in Europe and the Asia-Pacific region produced lower losses. A total of 2,900 people lost their lives in natural disasters in the first half of the year, much lower than the average figures for both the last 30 years and the last 10 years.
Torsten Jeworrek, Member of the Board of Management, MUNICH Re, said:
"The natural disaster statistics for the first half of 2020 point to two things in particular: One: severe thunderstorms in North America dominate the loss figures; this demonstrates the need to strengthen building resilience to mitigate losses. Two: this is especially relevant because climate change is likely to play a role in increasing the thunderstorm risk in North America in the long term. The world finally needs to take vigorous action to reduce greenhouse gas emissions in order to prevent losses and ensure we are not taken unawares by the consequences of climate change, as we were with the current coronavirus pandemic."
One of the largest severe thunderstorm outbreaks in 2020 occurred over the Easter weekend, when a strong frontal system over the Southeastern United States spawned dozens of tornadic thunderstorms and produced hailstones the size of tennis balls. A total of 140 tornadoes in 10 states were recorded, of which 3 reached EF4 intensity, the second-highest rating, with winds up to 300 km/h (186 mph). Countless homes were completely destroyed, and cars and buses were tossed into the air.
The strongest tornado in Mississippi's history was recorded during this outbreak. Its funnel was more than three and a half kilometres (2.25 miles) across at its widest point, and the twister stayed on the ground for almost 100 km (62 miles) before dissipating. Its path of destruction could be seen in satellite images, though fortunately the storm missed major population centers in the area. In total, the severe storms resulting from this outbreak caused overall losses of USD 3.4 billion, of which USD 2.6 billion was insured and 38 people lost their lives.
Another severe event occurred on 14 June in the city of Calgary in the Canadian Province of Alberta, when a hailstorm with stones also the size of tennis balls came crashing down as it passed over the city. Countless houses and cars were badly damaged, and many roads suffered flash flooding caused by torrential rainfall as the storm drains were blocked by hailstones. Some vehicles were almost completely submerged, and some drivers had to be rescued from the sudden raging waters around them. Overall losses came to some USD 1.2 billion, of which around 75% was insured. It was the highest loss from a thunderstorm in Canada's history.
In total, severe thunderstorms in North America were responsible for USD 27 billion of overall losses and for USD 20 billion of insured losses in the first half of the year.
The worst natural catastrophes occurred in Asia: In May, Cyclone Amphan caused extreme losses in India and Bangladesh. At times, Amphan was a so-called super cyclone - the highest category - with wind speeds of up to 260 km/h. When making landfall in West Bengal on the border with Bangladesh, the storm reached wind speeds of around 150 km/h. The high wind speeds, extreme precipitation and a metre-high storm surge caused extensive damage. Thousands of houses were destroyed, and millions of people were left without electricity. Some 135 people died and several million people were able to be evacuated. The evacuations were made all the more difficult by the corona pandemic, as fewer people were able to enter the shelters due to social distancing restrictions.
With total losses of around USD 11.5 billion, Amphan was one of the most expensive cyclones in the North Indian Ocean. The insured loss has not yet been determined, but is likely to account for a relatively small proportion of overall losses.
In China, heavy monsoon rainfall from June onwards led to severe river flooding of hundreds of rivers in many parts of the country. More than 100 people lost their lives. It is not yet possible to make a reliable estimate of the damage as the floods continued into July. According to initial estimates, however, the minimum total losses will be in the high single-digit billion range.
Winter storm Ciara (known as Sabine in Germany) was the costliest natural disaster in Europe. With winds of up to 200 km/h, it affected large parts of Europe in early February. Tens of thousands of people found themselves without electricity, and thousands of flights and major events, such as football matches, were cancelled. Although it was only a medium-strength winter storm, Ciara impacted a large swath of central Europe and produced a relatively high overall loss of USD 1.8 billion (EUR 1.6 billion), of which USD 1.2 billion (EUR 1.1 billion) was insured.
Bushfires in Australia in the 2019/2020 summer season produced unprecedented losses. Fuelled by an exceptionally severe drought and high temperatures, the annual bushfire season began much earlier than usual. Many fires flared out of control and burned for a very long time, close to holiday resorts and population centres along the southeast coast of the continent. Although bushfire risk was elevated due to natural climate oscillations during the southern hemisphere summer of 2019/2020, a number of studies suggest that climate change is also making bushfires in Australia more likely in the long term. The fire season also produced record loss amounts: overall losses came to around USD 2 billion, of which USD 1.6 billion was insured due to the high proportion of fire insurance cover for buildings.
