IN THE USA today, many Americans will be celebrating the first day of spring. Down under, of course, we have autumn while they’re having spring, but our first day of autumn was back on March 1st. Why do we have different dates for our seasons?
Americans tend to count the start of spring from the equinox, the day of the year when daylight hours and dark hours are equal.

At home, I check the weather before I get up on my phone using the WiFi internet connection I have in the lounge. It’s only very recently that WiFi was invented — 1996 — but Aussies are keen on technology and it’s really caught on.
WiFi was invented by that other great Australian institution, the CSIRO. It wasn’t the first local area network, but it worked the best of the technologies jostling for position back in the day.
Every two years, these two venerable scientific institutions team up to release a State of the Climate report.
