Climate measurements for 2023 were above the central estimate of climate model projections. The central estimates had us hitting 1.5C in 2030. That's not "inordinately alarmist".
Quite the opposite in fact. However 1.5C last year was still within the range of all models.
Last year was also the first year the global average land temp was more than 2C above pre-industrial times.
To me, the models seem to be within an acceptable error range.
Centrist can a broad term, but I wouldn't consider those working in the fossil fuel industry, or heavily invested in that industry to be centrist on this topic. Such people have too many conflicting priorities.

Fourier transforms are a pure math construct. They are not based on empirically derived electromagnetic evidence, or even specifically related to electromagnetics. Fourier transforms just arise from the mathematical realisation that any function can be expanded into a series of sine functions.
They are exactly the sort of pure maths stuff I was talking about, and definitely not a counter-example.

The climate models may look like they are just projecting an established trend, but they are the result of simulating all sorts of physical systems and interactions. Fluid flow based on heating, carbon sinks, etc, etc, etc.
