Freak flooding in Guadalajara after a massive hail storm. Pictures on BBC:
Six suburbs in the Mexican city of Guadalajara were carpeted in a thick layer of ice after a heavy hailstorm. The ice was up to 1.5m (5ft) thick in places, half-burying vehicles.
[...] Hailstorms form when warm, moist air from the surface rises upwards forming showers and storms. Temperatures higher up, even in summer, can get well below 0C and so ice crystals form along with something called "supercooled water" which then grows into pellets of ice.
In severe thunderstorms, air can rise rapidly and is able to hold up these hailstones and allow them to expand in size. Eventually they get too heavy and fall to the ground.
In warmer parts of the year, such as in Guadalajara which has maximum temperatures of around 31-32C [(87-90 °F)] in June, more moisture is available, contributing to the formation of hailstorms.
Temperatures this month have been higher than normal with Torreon, to the north of Guadalajara, reaching highs of 37C [(99 °F)].
Hm, I wonder if somebody is going to mention anthropogenic warming with this?

Assuming it was even possible, move mass on this scale and you’d slow the rotation of the earth in the same way a spinning ice skater slows as soon as they put their arms out.

According to holders inequality slowing the rotation will tend to cool the average temperature too by making it less uniform (cooler nights and hotter days).
