abstract = {Using environmental isotopes to study the variations in air temperature is a relatively new method in Vietnam. This is a new and reliable method. Using environmental isotopes to study the temperature variations in the past and predict the future changes is a matter of being interested and applied. This paper used the results of isotope analysis (T, D,   18O, 13C and 14C) to study the change in temperature of the air environment in the past and then projected to 2050. From contents of isotopes, based on the correlation with temperature, water age we could calculate air temperature conditions in the past and predict future changes. Results from the study showed that about 500 years ago to present, air temperature in Red River area continuously rises and amplitude ranges from 0.05 to 0.06 ℃ /year. By 2030 the average temperature of the air environment will be 23.75 ℃, by 2040 would be 24.10 ℃ and by 2050 is 25.20 ℃.}
