Climate change refers to any significant change in the state of the climate that persists for an extended period, typically decades or longer. 

The Intergovernmental Panel on Climate Change (IPCC), the leading scientific forum for climate analysis, tells us that planet earth is currently warming in a historically unprecedented manner. Global temperatures have risen by 0.85 degrees Celsius between 1880 and 2012 and the global amounts of snow and ice have drastically diminished. While there are multiple complex drivers, the IPCC suggests that these changes can be mainly attributed to excessive levels of human-induced greenhouse gas emission, particularly the burning of fossil fuels (coal, oil and gas) and the destruction of forests. Greenhouse gases collect in the atmosphere and, like a blanket, warm the surface of the earth. They are now at their highest levels in history. 

Evidence of climate change is seen in increased global average temperatures, rising sea levels, more frequent and intense storms and melting ice sheets and glaciers.

The environmental effects of climate change have major consequences for people all around the world. People living in poverty are most vulnerable, especially those who live in low-lying coastal areas such as islands in the Pacific. Climate change makes life harder and more dangerous for them, and adds to existing problems like food insecurity and water scarcity. 

We’ve already seen that droughts, cyclones and floods are more frequent, destroying homes and livelihoods. Seasons are less predictable and crops are failing, pushing millions into hunger. Sea levels are rising, forcing women, men and children to leave their homes and land. 

The social and economic impacts of climate change are making it more difficult for people to enjoy their basic human rights, including those related to food, health, water, housing and adequate standard of living.

We’ve seen the impact of climate change on the lives of the most vulnerable children we work with first-hand. Droughts, cyclones and floods are more frequent, destroying homes and livelihoods. Seasons are less predictable and crops are failing, pushing millions into hunger. Sea levels are rising, forcing women, men and children to leave their homes and land. 

The poor, especially children, are the most vulnerable to the effects of climate change. They are least able to protect themselves from its effects and they are least able to recover from climatic disasters. 

In short, climate change will affect almost every aspect of World Vision’s work and mission in the years to come. As one of the world’s leading aid and development organisations, World Vision recognises that to serve the poor faithfully, we must take the challenge of climate change seriously.

World Vision is working to tackle climate change through programming and advocacy efforts. 

We are committed to helping communities prepare themselves for climate change. Our work is focused on building communities’ resilience to the effects of climate change, for example through disaster preparedness planning and improving food and water security measures. We are also working to increase environment-enhancing development activities such as reforestation, agro-forestry, and conservation farming in World Vision’s programmes. 

World Vision further advocates with governments to reduce harmful greenhouse gas emissions and fulfil their climate-related commitments under the Paris Agreement as well as the Sustainable Development Goals.

Climate change is happening, and it is affecting the poorest communities that World Vision works with, especially those in New Zealand’s Pacific backyard. We know the most vulnerable, especially children, are the most susceptible to the devastating effects of climate change and changes to their environment are already affecting their lives.

Climate change threatens the future generations of Pacific children. Because they are still growing, children are at greatest risk of the impacts of climate change on food supply. The greatest killers of children – malnutrition, diarrhoeal disease and malaria – will increase because of climate change.

A healthy environment is the basis for the future of children.

Climate change is a developmental problem, not just an environmental one. Many of the countries most vulnerable to extreme weather events and a changing climate are also those least able to afford to prepare for the worst, and these are countries where World Vision works. 

Climate change is threatening food security, agriculture, water supplies, economic development and health of the most vulnerable communities, especially children. Extreme weather conditions that are increasing as a result of climate change, pose health risks to communities, especially children. Diseases including diarrhoea, leptospirosis, cholera, and typhoid are increased by exposure to contaminated water or decreased hygiene due to water shortages. These diseases have the potential to kill children.

As sea levels rise climate change could cause large scale displacement of low lying regions, and affect crops and water supplies, threatening communities cultural connection with their land and their livelihood.

World Vision is working to help build sustainable resilience around the globe, including in the Pacific, to the effects of climate change.
