Radioactive materials from these nuclear tests mixed with debris from the blast, fell to the earth with rain, or were spread by the wind, exposing hundreds of thousands of people to dangerous levels of radiation. The fallout from atmospheric tests created a global health crisisand scientists raised the alarm.

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.
