The greenhouse effect is a natural phenomenon.
In this process gases in earth’s atmosphere trap solar heat.
It is crucial to keeping our planet at a suitable temperature for life.
It makes earth much warmer than it would be without an atmosphere.
But human activities are increasing much more than normal.
Clearing forests, burning fossil fuels etc are increasing greenhouse gases.
Methane, carbon dioxide, water vapors etc are the major greenhouse gases.
It has also resulted in global warming.
Rise in the level of the sea, submergence of island and coastal cities are the major consequences.
We can reduce greenhouse gas emissions by switching to renewable sources of energy and using less fossil fuels.
