Stories of tremendous forest fires, huge storm events, and suffocating heatwaves have dominated headlines over the past few years. We instinctively feel that our weather is getting wilder. Are we finally living through those climate change warnings we’ve heeded for decades?
A marine heatwave is happening all around New Zealand. Warmer waters are more pleasant for swimming in and can create wilder weather. But what do they mean for fishing? Let’s dive into the science behind getting a good catch.
