This is producing changes in the earth’s climate and weather which have implications for gastrointestinal health and disease. Climate change will exacerbate current challenges with regard to provision of adequate nutrition and access to clean water. An increase in high rainfall events, flooding and droughts will be associated with an increase in enteric infections and hepatitis. Changes in habitat may result in altered distribution of gastrointestinal illness such as Vibrio cholera. Climate change will force migration between countries, and within countries, and will drive relocation from rural to urban areas, further straining sanitation and clean water provision. The infrastructure required to the delivery of gastrointestinal care is vulnerable to extreme weather events which will become more frequent. The Gastroenterology community needs to join the debate on climate change by organizing, educating, advocating, and supporting our political leaders as they face the enormous challenges posed by global warming.
