Visualizing the Impact of Rising Sea Levels, by Country


This post is by Carmen Ang from Visual Capitalist


Climate change is already causing sea levels to rise across the globe. In the 20th century alone, it’s estimated that the mean global sea level rose by 11-16 cm.

How much will sea levels change in the coming years, and how will it affect our population?

In the below series of visualizations by Florent Lavergne, we can see how rising sea levels could impact countries in terms of flood risk by the year 2100.

These graphics use data from a 2019 study by Scott Kulp and Benjamin Strauss. Their study used CoastalDEM—a 3D graphics tool used to measure a population’s potential exposure to extreme coastal water levels—and examined rising sea levels under different levels of greenhouse gas (GHG) emissions.

Flood Risk By Region

Which countries will be most severely affected by rising sea levels?

If things continue as they are, roughly 360 million people around the world could be at risk of annual flood events by 2100. Here’s what those figures look like across each region:

Africa

Number of people in Africa that will be affected by rising sea levels in 2100

On the continent of Africa, one of the countries with the highest number of people at risk of coastal flooding is Egypt.

Over 95% of Egypt’s population lives along the Nile river, with some areas situated at extremely low elevations. The country’s lowest point is 133 m below sea level.

Asia

Number of people in Asia that will be affected by rising sea levels in 2100

Asia’s population will be more heavily impacted by flooding than any other region included in the dataset.

According to the projections, 70% of the people that will be affected (Read more...)

Interactive: Natural Disasters Around the World Since 1900

While natural disasters are inevitable and commonplace within the context of human history, that doesn’t lessen our collective shock when they occur.

Here are just a few of the natural disasters that made headlines last year:

  • Haiti was rocked by a 7.2 magnitude earthquake that killed more than 2,000 people Tens of thousands of homes were damaged or destroyed.
  • Super typhoon, Rai, killed 375 people in the Philippines. The storm brought winds as high as 120 mph (193 kph)
  • Landslides in China’s Henan province kill more than 300 people
  • Historic flooding results in more than 200 fatalities in Germany and Belgium
  • Hurricane Ida battered the Gulf Coast, killing 91 people across nine U.S. states

And these are just some of the many events that rounded out a long list of disasters in 2021.

The interactive dashboard above was created by Our World in Data, using data came from EM-DAT, the International Disaster Database. The database aims to rationalize decision making for disaster preparedness and to provide an objective base for vulnerability assessment.

Total Deaths by Natural Disaster in the Last Decade (2010-2019)

In the past decade, approximately 60,000 people per year died from natural disasters. This represents 0.1% of total deaths worldwide.

The chart below breaks down the total deaths by type of natural disaster in the last decade.
