Switzerland's glaciers have lost ice volume every year since 2001

How melting ice impacts the whole world

Melting glaciers and ice caps are far from where most people live, but their impact can be felt across the planet. Visit four places—the American West, a Himalayan valley, the northern Atlantic, and Texas—with this immersive interactive to see the various impacts of melting ice around the world.

During glacier surging, these bodies of ice can move over half a football field a day

The movement of these glaciers, which repeatedly speed up and advance for months or years after stalling or moving backward for a time, results from melting ice that reduces friction between them and the ground, allowing them to slide more quickly. Scientists note that this effect is becoming more frequent due to climate change.

Glacial ice loss can be determined by listening to escaping bubbles

Glaciers form from the accumulation of layers of snowfall over hundreds to thousands of years, trapping air bubbles that serve as time capsules of atmospheric conditions at the time. When glaciers melt, these bubbles produce a distinctive sound that can be detected by underwater microphones, allowing assessment of melting from a safe distance.

Earth has shifted between extreme warming and cooling phases for 500 million years

Earth is in an interglacial period of the Quaternary glaciation, resulting in receding glaciers and mild temperatures. However, today's warming trend is occurring much faster than previous warming periods in the climate record.

Switzerland's currency is so strong that it could cause deflation

Economic instability in the United States in 2025 strongly benefited Switzerland, where the value of the franc relative to the dollar increased by about 12.7%. In response, the price of imports dramatically decreased, making goods overall much cheaper.

Climate models have predicted sea level rise almost perfectly since the 1990s

The rise in sea levels is primarily due to melting ice in Greenland and Antarctica, and predicted levels have been confirmed accurate by satellite observations. Ocean currents influence regional variations in sea level rise, which are expected to accelerate.

There may be 500,000 additional malaria deaths by 2050

Research published in the journal Nature in January 2026 estimates that by 2050, climate change may trigger more than half a million additional malaria deaths and over 100 million additional malaria cases. The work is based on climate change projections and available disease information and did not incorporate new vaccine uptake.

Microplastics have been shown to disrupt photosynthesis in plants and algae

A major study found that pieces of plastic less than five millimeters long are causing an estimated 4% to 14% loss of the world's wheat, rice, and maize, potentially putting an additional 400 million people at risk of starvation within 20 years. The damage from microplastics to crops may already rival the impact of climate change on food supplies.

Butterfly populations have declined by 22% from 2000 to 2020

Research suggests that one in every five butterflies is lost due to pesticide use, habitat loss, and climate change. Playing a vital role in pollination, their declining populations threaten plant reproduction and the health of ecosystems.

Understanding how the commodification of water has contributed to global water scarcity

In 2010, the UN General Assembly recognized access to water and sanitation as a basic human right, noting that an estimated 884 million people worldwide lack access to safe drinking water. The treatment of water as a commodity and reserves as property has contributed to unequal access and competition over its use, which is expected to intensify due to climate change.

Yearly greenhouse gas emissions have been steadily increasing since 1850

Although greenhouse gases include methane, nitrous oxide, and most fluorinated compounds, their warming potential is often measured relative to carbon dioxide. In these units, greenhouse gas emissions have gone from 4.29 billion metric tons of carbon dioxide equivalent in 1850 to 54.43 billion metric tons in 2024.

From 2023 to 2025, coral reefs experienced their fourth global bleaching event

Heat stress from the 33-month-long event impacted about 84.4% of the world's coral reef area across waters in at least 83 countries and territories, making it the largest such event to date. Due to climate change, about 90% of coral reefs are expected to undergo bleaching annually by 2050, leaving insufficient time for recovery during the winter months between bleaching events.

Climate change is disrupting maple syrup by shortening its production season

The number of unusually warm winter days in parts of Maine has increased significantly over the past few decades, stressing maple trees into shifted sap flows and leaving producers with less consistent outputs.

Hurricane Helene dumped enough water to fill Lake Tahoe

Alongside a rainstorm that moved into the region ahead of it, the hurricane released an unprecedented 40 trillion gallons of rain on the southeastern US, causing catastrophic flooding and at least 100 deaths. Meteorologists suggest climate change is exacerbating the severity of such events.

Scientists can determine Earth's past climate conditions by analyzing air trapped in microscopic bubbles within ice cores—columns of compressed snow layers that build up over hundreds of thousands of years.

What happens to golf balls after they're used?

With over 1 billion golf balls produced annually, an estimated 300 million to 1.5 billion are lost worldwide. On average, thousands of balls are left behind on each course, often ending up in ponds, forests, and beaches. While many golf courses recover and reuse some of these balls, studies suggest countless remain unretrieved.

As of 2024, about 77% of the world's gold reserves have been mined

About 216 million metric tons—about 0.4% of the Great Pyramid of Giza's volume—have been extracted and used primarily for jewelry. The remaining reserves are estimated based on chemical analysis of rock samples extrapolated to the entire mass of Earth's crust.

Davos has faced backlash over private jet usage

For the 2022 Davos meeting, which focused on the climate crisis, approximately one in 10 attendees arrived by private jet, producing emissions equivalent to those of roughly 350,000 cars in a week. One recorded jet flight to Davos covered just 13 miles.

How do maps get their place names in multilingual areas?

In countries with multiple local dialects, cartographers struggle to standardize place names enough to create maps of the region. This process inevitably leads to conflict. Case in point, Switzerland, where in the late 1800s many dialects called the same places by different names, leading one alienated community to demand the return of its local names. Read about this and several other examples of contentious place-naming on maps here.
