Global Warming
and the
Greenhouse Effect
Our Earth receives most of its energy, called radiation, from the Sun.
地球大部分的能量，是得自接收太陽的輻射而來。
This energy is electromagnetic radiation in the form of Visible light, with small amounts of Infrared(IR) and Ultraviolet(UV).
這種能量是一種可見光形式的電磁輻射，並帶有少許紅外光和紫外光。
這種能量是一種可見光形式的電磁輻射，並帶有少許紅外光和紫外光。
The incoming Visible solar energy has a very short wavelength and passes through the atmosphere.
照射到地球上的可見太陽光能，波長很短，穿透大氣。
The Earth's surface absorbs the solar energy and releases it back to the atmosphere as Infrared(IR) radiation, some of which goes right back into space.
地球表面吸收了太陽能，並且以紅外線輻射的模式將其釋放回大氣中，其中部分的紅外線回到了太空。
But some of the IR radiation emitted by the Earth is absorbed by greenhouse gases in the atmosphere and sent back towards the Earth's surface. That warms the Earth's surface.
但是一些地球釋放出的紅外線輻射被大氣中的溫室氣體所吸收，並再度折回地表，造成地表增溫。
Three main gases in our atmosphere that contribute to the greenhouse effect are carbon dioxide(CO2), methane(CH4), and water(H2O).
地球大氣層中造成溫室效應的三種主要氣體為二氧化碳、甲烷和水。
These gases absorb the infrared radiation emitted by the Earth and re-radiate the energy as heat back towards the Earth, causing a warming known as the greenhouse effect.
地球大氣層中造成溫室效應的三種主要氣體為二氧化碳、甲烷和水。
These gases absorb the infrared radiation emitted by the Earth and re-radiate the energy as heat back towards the Earth, causing a warming known as the greenhouse effect.
這些氣體吸收地球釋放出的紅外線輻射，再度以熱的形式將能量輻射回地球，造成眾所周知的溫室效應所引起的暖化現象。
The warming due to greenhouse gases is expected to increase as humans add more greenhouse gases to the atmosphere.
當人類不斷增加大氣層中的溫室氣體時，溫室氣體造成的暖化現象也當然越來越明顯。
