Climate change, rising sea levels, desertification, torrential monsoons and melting glaciers are rapidly altering the landscape of our planet.

Click through for some of the many scenic locations in the world that could disappear in the next few decades.

Cerro Rico, Bolivia

Located near the city of Potosí, Cerro Rico (or Rich Hill) was once an important source of silver for the Spanish empire.

However, nearly 500 years of uncontrolled mining has resulted in the mountain becoming porous and unstable. In 2011, its famed peak was reported to be at the risk of collapsing and efforts were carried out to fill up a crater with ultra-light cement.

Also called the “mountain that eats men,” Cerro Rico was added to UNESCO’s List of World Heritage in Danger in 2014.

Athabasca Glacier, Canada

One of the most visited glaciers in North America, the Athabasca in Jasper National Park is a part of the Columbia Icefield and covers an area of 2.3 square miles (six square kilometers).

The glacier has been melting for the past 125 years, with its southern edge receding by nearly a mile. According to a Canadian Partnership Initiative of the UN Water for Life Decade Parks Canada official, “Even with substantial snow years, the summers are warm enough and the fall is prolonged enough that all of that snow goes and we’re still losing five meters [16.4 feet].”

Abu Mena, Egypt

The historic town is in danger of sinking due to the rising water table. Once known for its monastery complex and as a renowned Christian pilgrimage site, the ruins were added to UNESCO’s List of World Heritage in Danger in 2001.

The alarming rise in the water table was caused due to a World Bank-funded agricultural program in the region. The destruction of water tanks has caused widespread damage to the soil, increasing the risk of collapse of historical structures. As per a 2018 update of the World Heritage list, the site is still in danger.

The Alps

The Alps are more susceptible to climate change than the Rocky Mountains because the former sits at a lower altitude.

The Alps have suffered a rise in temperature by just under 35.6 degrees Fahrenheit (two degrees Celsius) over the past 120 years, which is almost twice the global average.

Around three percent of Alpine glacial ice is lost per year and researchers are anticipating a further increase in temperature by 35.6 degrees Fahrenheit (two degrees Celsius) in the next 40 years.

Seychelles

A tropical Shangri-la, the Seychelles comprise over a 100 islands in the Indian Ocean. A tourist hot spot (and home to several luxury resorts), they are in danger of beach erosion as global warming has devastated coral reefs that protect the shoreline.

In an interview with NPR, Ronald Jumeau, the country’s representative to the UN, noted that while Seychelles has hills, unlike other island nations such as Maldives and Tuvalu, 80 percent of the people live on the coast, and they’ll have to relocate as many islands of the archipelago could submerge over time with rising sea levels.

Maldives

As the world’s lowest country, almost 80 percent of Maldives’ islands are less than 3.2 feet (one meter) above sea level. The island nation could be entirely submerged over the next 100 years if sea levels continue to rise, as per a report by the World Bank.

The government has been trying to take the edge off the effects of climate change by encouraging afforestation and preventing beach erosion, and by cleaning litter and debris from coral reefs.

Glacier National Park, Montana, US

The Glacier National park had over 100 glaciers when it was established in 1910. In 2015, only 26 could be officially designated as active glaciers, as per the U.S. Geological Survey.

Rapid climate change resulting in snow avalanches and variations in the thickness of ice and dynamics of ice flow have caused the glaciers to shrink. If this continues, researchers predict there will be no glaciers left in the park by 2030.

Dead Sea

Over the last 30 years, the Dead Sea has shrunk by a third and sunk approximately 82 feet (25 meters). According to Israel’s Environmental Protection Ministry, the hyper-saline lake is receding at a rate of four feet (1.2 meters) per year.

National Geographic reported in 2018 that the 30-mile (48.2 kilometers) length of the Dead Sea is only half what it was a century ago.

Experts also believe it could shrink to the size of a pool in as little as 50 years, due to neighboring countries drawing water from the River Jordan, which is the only water source for the Dead Sea.

Venice, Italy

The Italian city of canals, considered one of the most romantic in the world, has long been sinking.

The Italian office of the World Wildlife Fund and conservationists Italia Nostra suggest Venice may face inundation due to rising sea levels.

A rise in the number of severe floods each year, as well as mass tourism, might make Venice uninhabitable by the end of the century.

Great Barrier Reef, Australia

The largest coral reef in the world has shrunk by more than half its size over the past 30 years due to rising temperatures.

In addition, coral bleaching by ocean acidification is another factor that leads scientists to believe the reefs could soon disappear.

A 2018 report published in Nature suggested that at least 30 percent of the reef’s corals died in a heatwave in 2016. Marine scientists have warned climate change will cause irreversible damage unless swift action is taken.

Everglades, Florida, US

From invasive species to polluted waters and damaging recreational activities, the subtropical wetland ecosystem of the Everglades has its share of troubles.

However, the wetlands, also known as “river of grass,” could be permanently altered if it is inundated with salt water due to a rise in sea level in coming decades, according to the U.S. National Park Service.

It was added to UNESCO’s List of World Heritage in Danger in 2010.

Solomon Islands

Solomon Islands is a sovereign country consisting of a large cluster of islands. Many islands in this archipelago “are being ravaged by rampant logging,” according to Conservation International amphibian expert Robin Moore.

Additionally, pronounced droughts and rising sea levels have adversely impacted water supplies and caused damage to crops and livelihood.

Atlantic Forest, South America

The species-rich Atlantic Forest originally spanned between 390,000 and 580,000 square miles (1,000,000 and 1,500,000 square kilometers), spreading across Brazil, Paraguay, Argentina and Uruguay.

According to the World Wide Fund For Nature, due to expansion of logging and agriculture, the forest is now less than seven percent its original size and exists mainly in isolated patches.

Mount Kilimanjaro, Tanzania

They’ve been around for nearly 10,000 years but Mount Kilimanjaro’s glaciers have shrunk by 80 percent in roughly the past century, according to the UN.

The combined impact of global warming and changes in land use have likely contributed to glacial decline. In 2009, scientists predicted the glaciers will be gone completely by 2022.

Rainforests of the Atsinanana, Madagascar

The rain forest was added to UNESCO’s List of World Heritage in Danger owing to poaching, illegal logging and the killing of lemurs (pictured) for bush meat.

Home to rich tropical rain forests and diverse wildlife, Madagascar is suffering from habitat loss due to illegal human activities.

South Patagonian Ice Field, Chile

According to researchers at Cornell University in the U.S., the Southern Patagonian Ice Field has lost ice at twice the rate between 2000 and 2002 than it did between 1975 and 2000.

Between 2000 and 2012, the ice field rapidly lost volume at many of its outlet glaciers. The meltwater from the ice field contributes to the increasing sea level.

Jerusalem

The historic city of Jerusalem and its walls were included in the UNESCO List of World Heritage in Danger mainly because of urban development.

Urban construction, teamed with a lack of conservation policy, is causing damage to the original buildings and diminishing the site’s cultural significance.
