2025 Where there is more snow, the temperatures will stay lower, because the snow will reflect much of the sun’s solar radiation. Judson Jones, New York Times, 22 Jan. 2025 Based on observations of the CMB radiation by the European Space Agency's Planck spacecraft, the standard model ...
The meaning of SOLAR SAIL is a propulsive device for a spacecraft that consists of a flat material (such as aluminized plastic) designed to receive thrust from solar radiation pressure.

The eerily named field of “solar radiation management”, for example, which has received significant financing from Bill Gates, envisages spraying particles into the stratosphere to cool the Earth by reflecting the Sun’s rays back into space. The risks are enormous, such as causing extreme ...
A leatherback may be able to pick up some body heat by basking at the surface; its dark, almost black body color may help it to absorb solar radiation. However, most of its internal heat comes from the action of its muscles.Leatherbacks keep their body heat in three different ways. The...
