Opening
According to phenomenon of 'butterfly effect' even a tiny change in climate change patterns in one part of the world has an impact on a distant part of the world. The monsoon is yet another example of this interconnection.
Body · points
IMPACT
(1) Irregularity of monsoon Rise in global temperatures -> Rise in sea surface temperatures -> change in arrival & departure of monsoon [Ex] Recent irregular flooding and rainfall in Kerala despite reversal of monsoon not kicking in.
(2) Increase in extreme weather events and cyclones [Ex] Rise in temperatures of Arabian sea & many more intense super cyclones in Arabian sea than a long time. -> Kyarr, Maha, Vayu (3) Effect on Indian Ocean Dipole - which has become positive -> greater rainfall in last 2 years (4) Impact on regularity of El Nino and La Nina phenomenon. -> Lack of rainfall in 2017-18 due to quicker appearance of El Nino (change in climate) (5) Climate change impact on sea level rise and greater evaporation also directly impacts amount of rainfall (6) Distribution of monsoon: -> Greater concentration in South India

The 6th IPCC Assessment report has also highlighted the specific impact of climate change on India - in term of rise in heatwaves and extreme weather events in South India
