Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C, with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.
Information about climate1 is used to make decisions every day. From farmers deciding
which crops to plant next season to mayors in large cities deciding how to prepare for future heat
waves, and from an insurance company assessing future flood risks to a national security planner
assessing future conflict risks from the impacts of drought, users of climate information span a
vast array of sectors in both the public and private spheres. Each of these communities has
different needs for climate data, with different time horizons (see Box 1) and different tolerances
Objectives of research: 1) To explore mechanism of the seasonal moisture transport in Vietnam. 2) To determine the relationship between the moisture transport and the ENSO event, especially in ENSO years which heavy rainfall or severe drought occurred in Vietnam. 3) To propose the application of the moisture transport information for monitoring droughts (during El Niño) and heavy rainfall (during La Niña) over Vietnam.
