As rising temperatures are creating more extreme heat events in regions all over the world, the term 'urban heat island' is becoming more familiar. But what are they and do they matter?

This heat is equivalent to more than three times the total power consumption of the entire world and drives important geological processes, such as the movement of tectonic plates and the flow of ...

A less obvious way is that snow cover makes an excellent radiator of Earth’s internal heat. On a clear, calm night, the air gets cool because so much heat is radiated into space from the ground ...

A new long-term animal study of cell-phone radiation suggests that emissions don't cause cancer, but studies by a second team hint that cell phones may cause damage in other ways.

In 1900, Max Planck came up with his famous equation, describing heat radiation of stars or glowing metal - but it is not applicable for very small objects. Physicists in Vienna have studied the ...
