Climate change at the scale of everyday systems

IMPACTS: Climates Change the World is an NHK WORLD-JAPAN series about the consequences of a warming planet. Its short reports connect scientific findings with the places, industries and ecosystems already experiencing change. Rather than building a single feature-length argument, the programme returns to individual problems and the responses being developed around them.

Agriculture provides several of its most concrete examples. Reports examine methane emissions from rice paddies, efforts to develop rice varieties that withstand hotter summers and stronger typhoons, and the decline of returning Japanese chum salmon. These subjects connect emissions, food production and ecological disruption without treating them as separate stories.

Engineering, conservation and adaptation

Other instalments look at low-emission concrete, the protection of Japanese rock ptarmigan, and the restoration of degraded peatlands in Scotland. An EXPO 2025 sequence follows carbon recycling, lower-carbon architecture, ocean education and projects to collect and recycle used fishing nets. The emphasis moves between reducing the causes of warming and adapting to damage already under way.

The island-focused report on nature-based responses to sea-level rise considers coral and star sand. Alongside the farming and construction stories, it gives the series a broad geographical reach while retaining a specific question in each instalment: what is changing, who is affected, and which response is being tested?

Episodes

S2025 · E01

Reducing Methane Emission from Rice Paddies

Emissions of methane gas, which has a strong effect on global warming, are at a peak. In Japan, where 40% of methane emissions come from rice farming, finding a solution is of great importance.

S2025 · E02

Facing the 1.5℃ Challenge

Global temperatures in 2024 exceeded the Paris Agreement target of 1.5℃ above the pre-industrial average. A recent Yokohama symposium and citizen initiatives suggest possible countermeasures.

S2025 · E03

Durable Environment-Friendly Concrete

As a constant supply of concrete is required for urbanization around the world, Japanese companies have developed concrete that emits no CO2 during production, and a CO2-absorbing material coating.

S2025 · E04

Protecting Rock Ptarmigan From Global Warming

Global warming is impacting ecosystems and bird habitats in the world's mountainous regions. In the Japanese Alps, various efforts are underway to protect the endangered Japanese rock ptarmigan.

S2025 · E05

EXPO 2025 ep.1 The Forefront of Carbon Recycling

The first of five episodes on EXPO 2025. Besides reducing CO2 emissions, a key factor in global warming, explore new ways to capture it from the atmosphere, in a cutting-edge Carbon Recycling Factory.

S2025 · E06

EXPO 2025 ep.2 Climate-Friendly Architecture

Architecture emits large amounts of CO2 globally through construction, transport and demolition. At the Netherlands and Swiss pavilions, new ideas and technology merge to control CO2 emissions.

S2025 · E07

EXPO 2025 ep. 3 BLUE OCEAN DOME: Reviving Our Oceans

With the theme of "revitalizing our oceans," BLUE OCEAN DOME aims to inspire action by visualizing the water cycle, marine biodiversity, and the seriousness of plastic pollution.

S2025 · E08

EXPO 2025 ep.4 Weaving the Future With Fishing Net Recycling

To help reduce the "ghost" marine debris that does not decompose, those involved in Japanese fisheries have launched a project to collect and recycle used fishing nets.

EXPO 2025 ep.5 Nature-Based Solutions to Sea Level Rise

The low-elevation South Pacific islands are seriously threatened by sea level rise due to global warming. Attempts are underway to raise them with Nature-based solutions, using star sand and coral.

S2025 · E10

Hope for the Future: Restoring Peatlands

Peatlands cover only 3% of the Earth's land surface, yet they store carbon more effectively than forests. In Scotland, a global beverage company has launched a project to restore degraded peatlands.

S2025 · E11

Endangered Journey: The Decline of Japan's Chum Salmon

Japanese chum salmon migrate over 20,000 kilometers in their return journey across the North Pacific. Global warming has caused an alarming decline in returning salmon and requires urgent action.

S2025 · E12

Rice Resilient to Climate Change

Climate change has begun to impact the food supply. In Japan, hotter summers and stronger typhoons are affecting rice. Researchers are now working to develop rice that can withstand such challenges.
