2021-5-10 · A greenhouse is full of windows that let in sunlight. That sunlight creates warmth. The big trick of a greenhouse is that it doesn’t let that warmth escape. That’s exactly how greenhouse gases act. They let sunlight pass through the atmosphere, but they …

2021-7-16 · Two characteristics of atmospheric gases determine the strength of their greenhouse effect. The first is their ability to absorb energy and radiate it (their “radiative efficiency”). The second is the atmospheric lifetime, which measures how long the gas stays in the atmosphere before natural processes (e.g., chemical reactions) remove it.
