溫室效應(yīng)是指大氣中的某些氣體，如二氧化碳、甲烷和水蒸氣等，能夠吸收和再輻射地球表面向外散發(fā)的熱量，使得地球表面的平均溫度比理論上的溫度高，這種現(xiàn)象被稱(chēng)為溫室效應(yīng)。溫室效應(yīng)是地球氣候變化的重要原因之一，也是人類(lèi)活動(dòng)所導(dǎo)致的全球變暖現(xiàn)象的主要驅(qū)動(dòng)因素。

英文翻譯：

The greenhouse effect refers to the phenomenon where certain gases, such as carbon dioxide, methane, and water vapor in the atmosphere, can absorb and re-radiate the heat emitted by the Earth's surface, resulting in the Earth's surface temperature being higher than it would be in the absence of these gases. The greenhouse effect is a significant cause of climate change and a major driving force behind global warming caused by human activities.
