The year 2020 rivalled 2016 as the world’s hottest recorded year despite the absence of a strong El Niño effect. Apart from the COVID-19 pandemic, the year was dominated by climate-related disasters. These were largely responsible for the 389 recorded events which resulted in 15,080 deaths, 98.4 million people affected, and economic losses of at least US$ 171.3 billion. The statistics used in this report are drawn from the latest updates in the emergency events database, EM-DAT, maintained by the Centre for Research on the Epidemiology of Disasters (CRED, UClouvain).
At the outset, it is acknowledged that these statistics pale in comparison with the ongoing COVID-19 pandemic which by the year’s end had claimed almost two million lives, resulted in more than 90 million confirmed cases, trillions of dollars in economic losses, and “extreme poverty back up to levels not seen in a generation” as the UN Secretary-General has said.
In comparison to the previous two decades (2000-2019), 2020 was higher than the annual average in terms of number of recorded events and the annual average of economic losses, which is US$ 151.6 billion. There were considerably fewer deaths compared to the annual average of 61,709 and fewer people directly affected compared to the annual average of 201.3 million people. This decrease in impacts is due to the absence of mass casualty events, such as the 2004 Indian Ocean Tsunami (227,000 deaths) and the 2010 Haiti Earthquake (222,500 deaths) or high impact events, such as the 2015/2016 drought in India (330 million people affected). However, in 2020 there were 26% more storms than the annual average of 102 events, 23% more floods than the annual average of 163 events, and 18% more flood deaths than the annual average of 5,233 deaths.
This snapshot of the year in climate and geophysical disaster events does not consider the overlap with the impacts of the on-going pandemic. The additional losses inflicted by these reported events likely impacted those who have already suffered loss of income and employment because of COVID-19, particularly those in low- and middle-income countries. Unravelling the impacts of one from the other is a challenge and may have contributed to under-reporting of the impacts of non-biological hazards during the year under review. There is an existing problem of chronic under-reporting of economic losses from disasters, particularly from low-income countries.
The impacts of the events were not equally shared: Asia experienced 41% of disaster events and 64% of total people affected. Heatwaves in Europe accounted for 42% of total reported deaths. In a year of record-breaking storms and wildfires the Americas suffered 53% of total economic losses, largely in the USA which experienced the bulk of the year’s most costly climate-related disasters. Indonesia had the highest number of disasters (29 total events), including 25 floods. However, India and China suffered the largest human impacts with 19.6 million people and 14.9 million people affected, respectively. Floods were the most common disasters worldwide (201 events), while storms affected the highest number of people (45.5 million) and caused the most economic losses (US$ 92.7 billion). Extreme temperatures were the deadliest type of disasters accounting for 42% of total deaths, followed closely by floods which accounted for 41% of total deaths.
Summer heat waves in Europe were the deadliest events for the 2nd year in a row. Heat waves in France, Belgium, the Netherlands, and the UK caused a total of 6,340 deaths, more than double the figures for heatwaves in 2019. According to the National Oceanic and Atmospheric Administration (NOAA), 2020 was the hottest year for the Northern Hemisphere on record, however, underreporting on the impact of heat waves in many countries likely leads to gross underestimations in global death tolls.
The impact of floods was felt heavily throughout Africa and Asia. In Africa, floods affected seven million people and caused 1,273 deaths, the highest figure since 2006. Somalia, Sudan, and South Sudan suffered seasonal flooding that affected approximately one million people in each country, while Kenya had the highest loss of life in Africa with 285 flood deaths. In South Asia, monsoon flooding, often associated with landslides, affected 5.4 million people in Bangladesh and caused 448 deaths in Nepal. In India, flooding was responsible for the 3rd deadliest event of the year costing 1,922 lives. China also faced significant flooding as a series of four summer floods across the country killed a total of 397 people, affected 14.3 million people, and caused US$ 21.8 billion in economic losses.
With 30 named storms, the 2020 Atlantic Ocean hurricane season broke the record for the highest number of named storms. Hurricane Eta was the most impactful of these storms, killing 394 people and affecting 7.1 million people in 10 countries stretching from Colombia to the USA. Honduras and Guatemala suffered the worst impacts with 4.6 million people and 2.4 million people affected, respectively. Despite the record in the Atlantic, Asia accounted for the highest number of people affected by storms in 2020. In May, Cyclone Amphan struck South Asia affecting a total of 18 million people in India and 2.6 million people in Bangladesh. In the latter part of the year, a series of storms in South-East Asia caused widespread damage. In Vietnam, six successive storms, combined with flooding and landslides over three months, killed a total of 294 people and affected 2.2 million people, and in the Philippines, five storms over the same period killed a total of 185 people and affected 9.2 million people. The quick succession of these storms in the same areas provided little respite for those affected.
Droughts were most heavily experienced across the Sahel, affecting a total of 13.4 million people in Mali, Burkina Faso, and Niger. Wildfires across the west coast of the USA marked the 3rd year in the past four years with US$ 10 billion-plus in economic losses due to wildfires. Finally, although it was a relatively quiet year for geophysical events, an earthquake that killed 115 people in Turkey served as a reminder of the severe threat of earthquakes, the deadliest type of disaster over the previous 20 years.
Overall, the most notable features of the year were significant flood events across East Africa, South Asia, and China; a record year in the number of storms in the Americas; a series of storms in quick succession to strike South-East Asia; and summer heat waves across Europe which accounted for the deadliest disaster events for the 2nd year in a row.
