In the atmospheric electrical discharge, a leader of a bolt of lightning can travel at speeds of 60,000 m/s (220,000 km/h), and can reach temperatures approaching 30,000 °C (54,000 °F), hot enough to fuse silica sand into glass
The average peak power output of a single lightning stroke is about a terawatt (1012 W) and the stroke lasts for around 30 microseconds.
Lightning rapidly heats the air in its immediate vicinity to around 20,000 °C (36,000 °F) – about three times the temperature of the surface of the Sun. This compresses the surrounding clear air and creates a supersonic shock wave which decays to an acoustic wave that is heard as thunder.

Turns out there is such a thing as being too young and too thin.
Arctic ice continued its decline this winter, with hardy, thicker old ice increasingly being replaced with quick-to-melt, thinner young ice, according to a new report by NASA and the National Snow and Ice Data Center.
These wind turbines are popping up in agricultural areas around Ontario. In an effort to minimize the effects of Global Warming, their purpose is to distribute the methane produced from the cow farts more evenly throughout the earth’s atmosphere.
