This was a great, succinct article. Here are a few key points that I noticed:

The important result here is that the efficiency of your air conditioner decreases as ∆T increases — e.g., as the outside temperature goes up.

the work required to keep your house at a fixed temperature Tc increases with the square of the temperature difference between inside and outside temperature, ΔT².

Let’s use the same numbers from the previous example: you want to keep your house at 75F. If climate change has increased the outside temperature from 96F to 100F, the energy your air conditioner consumes increases by (100-75)2/(96-75)2 = 252/212 — this is an increase in energy consumption of 42%!

Averaged over an entire day, the increase will be less than this because ∆T is smaller for much of the day (e.g., at night) But the result is robust: climate change is driving exponentially increasing energy demand for cooling.

People with financial means, who work in air-conditioned offices and live in climate-controlled homes, can handle rising temperatures by simply paying for more electricity.

However, a significant portion of the global population lives the hot life. These people live in homes without air conditioning, work outdoors or in warehouses or kitchens with no climate control.
