Sydney's biggest ever climate march

Estimates of precise numbers varied, as ever, with published figures ranging from 3000 to 60,000! I was there, and I'd put it somewhere in the middle. It was definitely big though, and it was colourful, and very uplifting.

There were groups from churches, political parties, local action groups, solar power aficionados, and health professionals. There was even a small pro-nuclear group, and two (brave?) chaps whose banners just read < coal / >.  (I've no idea what that means exactly, or whether they were pro or anti coal. Note to placard writers: don't get too cryptic!)

There was music, there were speeches from some very worthy personages, and there were giant and horribly realistic versions of Tony 'King Coal' Abbott and Malcolm 'Innovate' Turnbull to scare the children.

We eventually marched from the Domain rallying place down to the Opera House, where the giant polystyrene politicians could scare the tourists too.

We'd been asked to colour code ourselves by dress choice, and march in our coloured blocks. I chose white, which was the designated colour for medicos and scientists. Several of my fellow marchers carried giant cardboard mosquitoes, signifying presumably malaria and suchlike diseases we can look forward to in a warmer Australia.
