It is a phenomenon in which the temparture of the earth is increasing due to burning of fossil-fuel (coal,oil & gases). The earth's climate has undergone changes, both on global & regional scale, particularly in the last few decades. India has also unpredictable weather this year. the winters have lasted longer than usual, untimely rains before cutting of crops & sudden rise of temparture during the day.
How it happens?
The sun rays coming from the sun are very strong. the earth absorbs some heat & rest of it is reflected back.This reflected energy is blocked by the green house gases which are hanging in the atmosphere.
Effects of global warming
- Polar caps melting
- Economic consequences

The technologies of the automobiles engines, aircrafts emission, working of thermal plants have to be reviewed.
