From a terrible drought to an unprecedented deluge. That's how my journey has been in the past 24 hours.

I was in the heart of central India reporting on the impact climate change possibly had on agriculture which had led to a record breaking number of farmers to commit suicide.

That's when news of floods in Chennai broke.

So I leaped from one crisis to another and headed for Chennai.

The day's rainfall had broken a 100 year old record. The airport, trains, public transport: everything had shutdown as rivers and lakes breached their banks.

And I thought to myself: isn't this in all likelihood another event triggered by climate change?

With the Chennai airport inundated, we reached Bangalore and headed to Chennai. It was only when we reached Kancheepuram - 40km from Chennai - that we could see how rural Tamil Nadu had been hit apart from the state capital.

Acres and acres of agriculture and open land were in waist deep waters.

The road leading to Keranallur village has been swept away by flash floods and locals claim at least 10 villages have been cut off. That's just in one area. The number of marooned villages could well be at least around 50.

People scrambling to stay afloat

The main road leading to Chennai city from Sriperumbudur is in shambles with massive potholes and the first layer of tar now eaten by the flowing waters.

The surrounding suburbs have no electricity or hotels rooms. For several hours we looked wanting just a single room but failed. Finally, only at 130am over 30km away from the city, we managed to get a roof over our heads.

Most roads in low lying areas of Chennai are still flooded. Thousands are still stranded in their homes. The Cooum and Adyar rivers are in spate.

Almost 35 lakes are overflowing. As we crossed a bridge over the Cooum, the waters were still swelling though the rains have largely abated. The Chennai airport will remain shut until December 6.

Houses completely submerged in Chennai rains

Slums and encroachments on the banks were completely submerged. Thankfully the homeless say the civic body had put them in shelters and given them food too.

The armed forces and the disaster relief force have been engaged into relief operations and are doing a great job.

But the scale of the disaster is too massive for the Tamil Nadu government to handle it alone.

With the airport, railway and road transport badly hit and with businesses down, the city's losses will run into billions.
