I’ve found myself thinking a lot about this paper by Herold et al. over the past few days. It describes the far-reaching implications of climate change for health and agriculture across different regions within Australia.
In particular I keep thinking about the implications of these two graphs:
The first graph shows heatwave frequency and the second one shows heatwave amplitude different
with day within a year. This is different from the other common way of measuring heatwave intensity– magnitude–that looks at the average temperature across all heatwave days within a year. °C2 is a heatwave unit of measurement and isn’t the same thing as degrees Celsius.
There are many impacts and consequences associated with this model, but the frequency and scale of near- and far-future heatwaves alone should terrify us.
