biến đổi khí hậu
The term "climate change" has been around since the 19th century, but its meaning has evolved. Early usage referred to natural climate variations over time. In the late 20th century, the term gained prominence as scientists understood the impact of human activities on the Earth's climate. The term became associated with the anthropogenic greenhouse effect and its consequences, such as rising global temperatures, sea level rise, and extreme weather events. While "climate change" encompasses both natural and human-induced shifts, the current use often emphasizes the latter, highlighting the urgency of addressing the issue.
a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
