 This diagram explains us about the green house effect Basically what green house effect is is the Sun which emits Mostly long Radiation and shortwave radiation All these radiation come in in the morning or in the during daytime without any problem the atmosphere which has various kinds of gasses like oxygen nitrogen Little bit of carbon dioxide, etc if these radiations basically pass through and the solar radiation Part of it actually gets reflected back out into the space from these clouds Whatever reaches the earth here down Below part of it heats up the atmosphere or the earth's surface Some of it is used for growing plants. Some of it evaporates water and runs the hydrological cycle and During nighttime all this energy that has come in during daytime Generally will go back into the space as longwave radiation, which is infrared radiation So it comes in in shortwave and longwave But all of it tries to go back or will go back in longwave radiation now The gasses like co2 in the atmosphere Generally have the unique Capability to trap this infrared radiation that is going out and these gasses absorb the infrared radiation Keeping a part of the radiation that would have otherwise gone out within the atmosphere So this is called greenhouse effect and due to this effect Because of these gasses the atmosphere right now is at an average temperature of 59 degrees Fahrenheit Without this effect for example if there was no co2 in the atmosphere no greenhouse gases It's totally of oxygen and nitrogen all the energy that would come in in the Daytime if it had gone out in the nighttime the earth would be freezing at Zero degrees Fahrenheit. So at this at best temperature Nothing can grow on this planet and the planet would be Uninhabitable so this greenhouse effect is what is Turning this planet into a habitable planet by keeping the average temperature at About 59 degrees Fahrenheit this temperature is the temperature that we normally see Average over entire year at all places including North Pole South Pole Equator day night various seasons etc. So greenhouse effect is what is actually Making this planet habitable by warming up a little bit Unfortunately, if we emit more and more greenhouse gases into the atmosphere Like what we have been doing the co2 concentration has gone up from 275 parts per million to now about 370 parts per million if we keep on doing these kinds of things More and more energy thermal energy would be trapped inside the atmosphere and this 59 degrees temperature Is likely to increase and that's what we call global warming or climate change or Increase in this temperature is detrimental So the question is whether we should Blame greenhouse effect for this or global warming as a bad bad phenomena
