The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium.

At night, the cells lose heat to their surroundings, leaving them several degrees cooler than the ambient air due to radiative cooling. Fan and colleagues tested their device on a rooftop at Stanford, taking measurements on 10–13 October 2021. m solar radiation window from its current value of 0.65 Thermoelectric effect.

Also missing is any realization that clouds also contribute to the greenhouse effect (roughly 25% of the total) and so whether cloud changes warm or cool depends very much on where the clouds are (high clouds have a very different effect than low clouds for instance).

In fact, the recipe can be simpler still, for we now know that almost any material can turn glassy if it is cooled from its liquid state so fast that its atoms or molecules are arrested before they have a chance to form a well-ordered solid state. As a liquid cools, it can either harden into a glass, or crystallize. Perfect solution?

Up in flames After recording Canada’s highest ever temperature on 29 June 2021, Lytton in British Columbia had to be evacuated as wildfires engulfed the town and destroyed most of its buildings. On balance, clouds nearer the stratosphere warm us, whereas low-lying clouds tend to cool us because their greenhouse effect is smaller.
