The Climate Witness Project (CWP) is a campaign of the Office of Social Justice and World Renew that grows out of several convictions of the Christian Reformed Church. The first is that there is scientific consensus that climate change is damaging our world. Human-made emissions of carbon dioxide and other greenhouse gases are changing the weather, melting polar ice caps, enabling diseases and viruses that have existed only in warm regions to move to more temperate zones, destroying species of animals and plants, and raising sea levels. In addition, there have recently been more prolonged and extreme droughts, more torrential flooding, readings that indicate warmer and more acidic ocean water, and consequent large-scale migrations of peoples and increases in food insecurity around the world.
