There have been strident claims that New Zealand is warming. The Inter-governmental Panel on Climate Change (IPCC), among other organisations and scientists, allege that, along with the rest of the world, we have been heating up for over 100 years.
But now, a simple check of publicly-available information proves these claims wrong. In fact, New Zealand’s temperature has been remarkably stable for a century and a half. So what’s going on?
New Zealand’s National Institute of Water & Atmospheric Research (NIWA) is responsible for New Zealand’s National Climate Database. This database, available online, holds all New Zealand’s climate data, including temperature readings, since the 1850s. Anybody can go and get the data for free. That’s what we did, and we made our own graph.
