Climate change cannot be ignored while we strive to preserve the nature and support the poor and vulnerable. Projected climate changes include strengthening of monsoon circulation, increases in surface temperature, increases in the magnitude and frequency of extreme rainfall events, and sea level rise. These changes could result in major impacts on the country's and region’s ecosystems and biodiversity; hydrology and water resources; agriculture, forestry, and fisheries; mountains and coastal lands; and human settlements and human health. Adaptation is not an option; it is a must, if we are to avoid the most serious impacts of climate change. The Government of Viet Nam has placed high priority on the emerging issues of climate change. IUCN regards climate change as one of its important foci and is developing leading edge knowledge on the potential impacts of climate change with special attention to biodiversity and the links to poverty.
