The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat to make the earth surface warmer leading to global warming.

2. GREEN HOUSE EFFECT
• The atmosphere allows most of the visible light from the Sun to pass
through and reach Earth’s surface.
• As Earth’s surface is heated by sunlight, it radiates part of this
energy back toward space as infrared radiation.
• This radiation, unlike visible light, tends to be absorbed by the
greenhouse gases in the atmosphere, raising its temperature.
• The heated atmosphere in turn radiates infrared radiation back
toward Earth’s surface heating it further.
• The greenhouse effect is a warming of the earth's surface and
lower atmosphere by green house gases.

3. GREEN HOUSE EFFECT
• Although the greenhouse effect is a naturally occurring
phenomenon, it is possible that the effect could be intensified by the
emission of greenhouse gases into the atmosphere as the result of
human activity.
• The magnitude of the enhanced greenhouse effect is influenced by
various complex interactions in the earth-ocean-atmosphere system.
• Runaway Greenhouse Effect is a phenomenon occurs when the
planet absorbs more radiations than it can radiate back. Thus, the
heat lost from the earth’s surface is less and the temperature of the
planet keeps rising.

12. GREEN HOUSE EFFECT
MITIGATION
• By reductions in the concentrations of greenhouse gases, either by
reducing their sources or by increasing capacity of their sinks.
• By reducing energy demand by increasing energy efficiency, phasing
out fossil fuels by switching to low-carbon energy sources.
• By adopting renewable energy sources like solar, wind, and hydro
power.
• By developing more sustainable transport and use of biofuels.
• By sustainable uses of land and forests resources / reforestation.
• Promote innovation and technology transfer for sustainable energy
breakthroughs.
