Some of the solar rays reaching the earth’s atmosphere are emitted back into space, the rest is absorbable by the oceans and terrestrials which heat the Earth. This heat is trapped by some of the greenhouse gases in the atmosphere, warming the earth to sustain life. However, trapping extra heat causes the rise in temperature of the earth resulting in global warming. Global warming is the eventual heating of the earth’s surface, atmosphere, oceans which begins with the greenhouse effect. Difference Between Greenhouse Effect and Global Warming Although used interchangeably, global warming and greenhouse effects are altogether different aspects. Let us take a look at how different both are from each other. Greenhouse Effect Global Warming What does it mean? It is the heat which escapes in the space, the greenhouse gases block this escaping heat and hence it enters the earth The earth gets overheated by greenhouse gas...

1. What is the greenhouse effect? In a greenhouse, sunlight enters, and heat is retained. The greenhouse effect describes a similar phenomenon on a planetary scale but, instead of the glass of a greenhouse, certain gases are increasingly raising global temperatures. The surface of the Earth absorbs just under half of the sun’s energy, while the atmosphere absorbs 23 per cent, and the rest is reflected back into space. Natural processes ensure that the amount of incoming and outgoing energy is equal, keeping the planet’s temperature stable. However, human activity is resulting in the increased emission of so-called greenhouse gases (GHGs) which, unlike other atmospheric gases such as oxygen and nitrogen, becomes trapped in the atmosphere, unable to escape the planet. This energy returns to the surface, where it is reabsorbed. Because more energy enters than exits the planet, surface temperatures increase until a new balance is achieved.

This temperature increase has long-term, adverse effects on the climate, and affects a myriad of natural systems. Effects include increases in the frequency and intensity of extreme weather events – including flooding, droughts, wildfires and hurricanes – that affect millions of people and cause trillions in economic losses. “Human-caused greenhouse gas emissions endanger human and environmental health,” says Mark Ra...
