PROFESSOR JAMES RENWICK
Climate is what you expect, and weather is what you get. What we expect is the changing of the seasons and that difference between summer and winter year to year. There might be some ups and downs, but broadly speaking, things are like they were in the past or that’s – that’s the way it used to be at least. The weather is the day to day. It’s raining in Wellington today, it was sunny yesterday afternoon, and just the day-to-day ups and downs of temperatures, clouds, rain.
The one way to think about the climate is it’s just the average of all the weather. And in a way, that’s true, but there’s a bit more to it than that. Think about the changing seasons. Every year, we have summer and winter, with spring and autumn in between. It doesn’t actually matter what the weather is doing. It will be warmer in the summer regardless of the weather, and it will be colder in the winter regardless of the weather.
One good way of thinking about it is that they’re different timescales. The weather is day to day, and the climate is year to year and longer really – or season to season at least.
