The impacts that climate change brings are extremely negative, affecting the weather, nature or even life, economy and society.
After a period of time under the influence of prolonged heat and heat, on November 24, Hanoi received a cold air wave with scattered showers and thunderstorms in many places. However, this cold front came much later than previous years, due to climate change as well as global warming.
Hanoi welcomes a late cold air wave with scattered thunderstorms.
In recent years, the air temperature in Vietnam tends to increase significantly. Specifically, the average annual temperature increases by about 0.5ºC nationwide and especially increases sharply in the summer months, lasting until the end of autumn in the North.
According to a report of the National Center for Hydro-Meteorological Forecasting, in 2020, the North will receive the first cold wave in the second half of September. In 2021, it will not be until mid-October in the North. cold. And finally, until 2022, it was not until November that people in the North could feel a little bit of the atmosphere of winter. This is a clear proof that the climate in Vietnam as well as the whole world is changing heavily, the hot sun lasts through the half of autumn, and the cold air becomes "scarce" and comes much later. much year by year.
The streets of Hanoi are still hot and sunny in the last months of the year.
Causes of climate change in Vietnam
Dr. Nguyen Ngoc Huy, Expert on Climate Change and Disaster Risk Management, said that climate change in Vietnam has two causes.
In terms of subjective causes, climate is largely influenced by human causes. Due to the needs of living and labor, people have not stopped using natural resources. Along with that, the large amount of emissions in the process of living, such as smoke from motorbikes, cars or factory emissions, increasingly cause the concentration of CO2 in the air to skyrocket.
Regarding objective causes, in addition to man-made causes, nature is also part of the cause. Changes in natural operating principles, changes in Earth's orbit, etc. also cause climate change. Along with that, the tectonic process, changing the direction of nature is also a cause of climate change in Vietnam that cannot be ignored.

Situation of climate change in Vietnam
In addition to causing prolonged heat, climate change also has many serious impacts on nature and people in Vietnam.
According to Dr. Nguyen Ngoc Huy, an expert on Climate Change and Disaster Risk Management, droughts and heat waves tend to increase and are uneven across regions, especially in the Central region and the Mekong Delta. The South... the impact of climate change causes great loss of life, property, economic, cultural and social infrastructure and adverse impacts on the environment.
Drought occurred in Kien Giang due to the influence of climate change.
In addition, not only drought, the occurrence of heavy rains, flash floods, floods, high tides deeply affects people's lives and activities, and affects the national socio-economic development. severe damage to property and people. Specifically, the average sea level has increased by 25-30 cm over the past 50 years. If sea level rises by 1m, about 10-12% of our population will be affected and GDP may lose about 10%.
"In recent years, I feel that the weather is getting worse and worse. It's already November in winter, but Hanoi's weather is still as hot as summer, but suddenly rain can bring cold air along with degrees of humidity. High humidity. Frequent and erratic weather changes cause not only me but also many people around me to be affected in terms of health and spirit", said friend Tran Duc Anh, currently living and working in Hanoi. .

Solutions to respond to climate change in Vietnam
Along with researching and finding solutions, urgent action is needed to minimize the impact of climate change such as: planting forests, using clean technology, reducing CO2 emissions into the air...
In the short term, it is necessary to plant and protect forests, do well in environmental protection, and contribute to mitigating climate change in Vietnam. Next, it is necessary to raise public awareness about climate and climate change in Vietnam in order to have ways to adapt to climate change (living with storms, floods...).
Finally, it is necessary to always focus on economic development, but must ensure sustainable development on the principle of respecting the laws of nature and finding ways to adapt to climate change and natural disasters.
