Ian Wishart: Major NIWA climate change study gets shredded in OpenAI’s ChatGPT peer-review

Media runs with bad data, again

On 2 July, the NZ Herald republished an opinion piece by Auckland University’s Dr Tim Welch, which, among other things, stated:

“It’s getting hotter. Niwa data shows New Zealand is already experiencing extreme temperatures five times more frequently than historical baselines. Wellington hit 30.3°C and Hamilton 32.9°C in January, both all-time records. Marine heatwaves are persisting around South Island coasts months longer than usual.”

Sure enough, subsequent temperatures showed a 0.3-0.4°C upward spike.
