Detailed explanation-1: -’Greenhouse gases’ are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth’s surface into space and the Earth would have an average temperature of about-20°C.

Detailed explanation-2: -The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.

Detailed explanation-3: -Identified by scientists as far back as the 1800s, the greenhouse effect is the natural warming of the earth that results when gases in the atmosphere trap heat from the sun that would otherwise escape into space.

Detailed explanation-4: -Greenhouse gases The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.

Detailed explanation-5: -The ‘greenhouse effect’ is the warming that happens when certain gases in Earth’s atmosphere trap heat. These gases let in light but, like the glass walls of a greenhouse, keep heat from escaping. First, sunlight shines onto the Earth’s surface, where it is absorbed and then radiates back into the atmosphere as heat.
