Clouds and El Nino

After the turn of the century, I became interested in climate science. But unlike almost everyone else, I wasn’t surprised by how much the global temperature was changing. As someone with experience with heat engines and engine governors, I know how hard it is to keep a heat engine stable under a changing load. As a result, I was surprised at how little the temperature was changing.
Over the 20th Century, for example, the temperature changed by a trivially small ±0.3°C. Since the average temperature of the planet is on the order of 287K, this means that the global temperature varied only about a tenth of one percent in a hundred years … that that is amazingly stable.

Scientists Have Found The ‘Missing Link’ From Sunspot Activity To Cosmic Rays-Clouds To Climate Change

Hailed as ‘the last piece of the puzzle’ in codifying our understanding of the mechanism(s) that cause climate changes, scientists are increasingly turning to Sun-modulated cosmic ray flux and cloud cover variations as the explanation for decadal- and centennial-scale global warming and cooling. In other words, climate changes are increasingly being attributed to natural variability, not anthropogenic activity.

Las nubes influyen decisivamente en el clima

La nubosidad es la pariente pobre olvidada en el análisis del clima terrestre.

What Is The Surface Area Of A Cloud?

Or what is the surface area of any fractal solid?
This is strongly related to the Coastline Paradox:  https://en.wikipedia.org/wiki/Coastline_paradox
Just with the added dimension of a solid.
It all comes down to the interaction of a bunch of surfaces and volumes with fractal geometry. Good luck with that…
So I’m now trying to figure out some way past this conundrum. How do you weigh a cloud? Without mass, volume, and surface area; how do you compute thermo properties and effects?
I think I see why they say “modeling clouds is hard”. It may be impossible.
