Jam today.....

I have just returned from Honolulu
I was amazed to see the early morning traffic of 12 jammed lanes 
These massive numbers of vehicles each pumping out exhaust fumes really did make it

Jam

hard to breathe and my eyes stung continually... 
It must be the same in China too
Until you see this sort of thing one can dismiss the global warming warnings as spurious but the realisation  soon dawns that Victorian Chimneys were not alone in causing damage to the atmosphere
