Snow in Lisbon

For the first time ever, I've witnessed a snow fall in Lisbon:

(there's a couple more photos for your perusal).

It's currently 2 to 3 Celsius outside (up a bit from where it was around lunchtime, when it started) and the snow is turning into a light drizzle now and then (so it's melting away before it has a chance to cover anything) but it's definitely snow.

I'm sure we're going to spend a while tomorrow cracking Ice Age jokes, but could the rest of the human race please stop making a mess of the environment?
