Evidence base
Five signals, one connected Pacific story
The charts and country lens use five official indicators to follow a simple question: how can climate pressure move from the ocean, through communities and food systems, into household costs?
Opening story
The ocean is moving closer to daily life
Pacific communities have always lived with the ocean. It feeds families, connects islands, protects shorelines through reefs and mangroves, supports culture, and carries trade.
But the relationship is under pressure. Higher seas reach further inland. Heavy rain and drought make food and water less reliable. Disasters damage homes, roads, wharves, schools, clinics, boats, and gardens. When these systems are disrupted, the cost does not stay in the environment. It moves into markets, transport, public budgets, and family decisions.
This website follows that movement: from rising seas to rising costs of living.
Regional starting point
One ocean, many local frontlines
The Pacific is connected by one ocean, but climate pressure is felt differently from country to country. A low-lying atoll may face saltwater in wells and gardens. A larger island country may face coastal erosion, flooded roads, landslides, crop losses, and transport disruption.

The map shows where the story begins. The data shows how the pressure travels.
A regional view gives scale. The country lens makes it practical by asking where each place can see pressure before it becomes household hardship.

Five signals that connect climate pressure to daily life
Choose a country and follow the same five signals through the charts below. Each signal tells one part of the story: sea-level pressure, rainfall change, disaster cost, people directly affected, and food-system pressure.
Data coverage differs by country and indicator. The charts should be read as evidence signals, not as a complete ranking of vulnerability.

Forecast-style scenario
What happens if the pressure keeps building?
This is not a prediction of one single future. It is a practical scenario showing how connected pressures can build over time if climate risks continue to intensify.
Imagine a coastal Pacific community over the next decade. King tides reach further inland. A road floods more often. A garden is damaged by saltwater after storms. Fishing becomes less reliable in warmer periods. Heavy rain delays transport to the market.
At first, these may look like separate problems. For a family, they add up: more money spent on food, more time spent travelling, more income lost, and more savings used for repairs.
Scenario message
The future cost of climate change is not only the damage after a disaster. It is also the slow rise in everyday pressure before and after disasters happen.
Household Budget View
Climate pressure becomes real when families spend more to live the same life
Rising seas and changing climate conditions may begin as environmental signals, but the cost is often felt at the market, at home, on the road, and in the family budget.
For many Pacific families, climate change does not first appear as a scientific term. It appears as a higher food price, a damaged roof, a flooded footpath, a failed garden, a longer boat trip, or a school day missed after heavy rain.
A family may spend more on rice because local crops were damaged. They may spend more on fuel because travel takes longer. They may spend more on repairs after flooding. They may lose income because fishing was poor, the market road was closed, or a small business could not open after a storm.
These are not separate costs. They are connected costs. The ocean changes, the coastline weakens, food and transport systems come under pressure, and households are left to carry more of the burden.
Cost pathway
from ocean pressure to household bill
01 Sea pressure
02 Coastline stress
03 Food and transport
04 Income pressure
05 Household bill
Food
When gardens, crops, and fisheries are disrupted, families may depend more on purchased or imported food. That can make meals more expensive and less reliable.
Housing
Flooding, erosion, strong winds, and storm surge can damage homes and increase the cost of repairs, rebuilding, or relocation.
Transport
Damaged roads, wharves, bridges, and coastal routes can make travel longer, fuel costs higher, and goods harder to move.
Income
Fishing, farming, tourism, roadside markets, and small businesses can lose income when climate shocks interrupt daily work.
Health and wellbeing
Water stress, heat, flooding, food insecurity, and relocation pressure can increase stress on families and communities.

Papua New Guinea
Coastal pressure, food systems, and transport risk
Papua New Guinea is not a low-lying atoll, but many communities still face coastal erosion, flooding, landslides, food-system pressure, and transport disruption. When roads, gardens, coastal homes, or market access are affected, the climate cost can move quickly into household spending and income.
Country pressure chain
Papua New Guinea
Ocean and rainfall pressure → damaged coastlines, roads, and gardens → weaker market access and income → higher household costs.
Homes, coastal villages, roads, gardens, ports, markets, and rural livelihoods.
Higher food prices, repair costs, lost income, longer travel, and pressure to move away from unsafe areas.
Safer roads, protected coastlines, stronger food systems, early warning, and local planning.
Real-life pressure points
The data shows the signal. Real situations show where the pressure lands.
Country highlights connect the five indicators to real Pacific situations such as coastal erosion, flooding, saltwater intrusion, disaster loss, affected households, and food pressure.
How to read this section: The examples are not separate stories. They show where the same pressure chain touches land, food, homes, income, and community decisions.
Reading the story honestly
This is a pressure chain, not a one-line cause.
This story does not claim that sea-level rise alone causes inflation. The stronger and more honest message is that climate shocks travel through connected systems: damaged infrastructure, disrupted households, food pressure, recovery spending, lost income, and public budget strain.
