Global warming

Global warming is the rise in the average temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth’s mean surface temperature has increased by about 0.8 °C

Global warming potential (GWP)

Global Warming Potential (GWP) is an index, based upon radiate attributes of greenhouse gases, compared to that of carbon dioxide. The global warming potential appears as the combined effect of the various lengths of time that these gases remain in the atmosphere and their relative effectiveness in absorbing outgoing infrared radiation.

Greenhouse Effect

Greenhouse Effect is heating of the planet due to the increased density of the trace greenhouse gases in the atmosphere. They have the effect of increasing absorption of sunlight by preventing the outward radiation of heat from the Earth.
