Is Winter here?

Diwali has come and gone. Its the time of the year when Indian climate undergoes a change and the chill sets in. Its the time of bye-bye monsoon and the onset of winter.
But looking at the Bangalore climate, it doesn't appear so. The mornings as usual all 12 months are chilly but by 10am its blistering hot.
Where have those cool afternoons gone?
Same was the case with monsoon too. It didn't rain when it was supposed to, and rained when it shouldn't. The barren areas had ample rainfall and even floods while the fertile plains had a drought.
Is it the El-Nino playing tricks or are we having a climate pattern change, the global warming to be blamed.

With industrialized and developing countries adamant on not taking the pollution level cut and adhere to the Kyoto protocol,
Pray God save the EARTH.
