The greenhouse effect in more depth

There is little doubt that the global earth temperature would be averaging 25-30° C colder without the greenhouse effect than it is today. That is a huge deal! Without the greenhouse effect, we would be looking at a global temperature at about -15° C instead of the +15° C that we enjoy today. In that case, our blue-green planet might look more like a dirty and lifeless snowball. The greenhouse effect is an essential natural mechanism. It helps regulate the Earth‘s temperature, making it more stable and able to sustain all life as we know it.
HEAT INPUT
The effects of the greenhouse gasses start with the sun‘s golden rays coming to Earth, as seen in Figure – 1. Warming the planet during the day with a Total Solar Irradiance (TSI) average of about 341 Watts per square meter W/M2.
