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?

    If this is true why don't we just move the surface of the earth up a few meters so it cools down?

      Then let's just take air out the atmosphere to reduce the pressure. The effect is the same.

        No, see, then all the Sasquatch would come down out of the mountains to breathe air of their accustomed density. Plus, what about the beings living in the hollow earth? Won't they suffer from such an act? And anyway, if we just wait, won't the air just fall off the edges of the flat earth?

        I mean, come on. This hot global warning, er, warming, stuff is totally #fakenudes. Er... Fakeknews. No no, #fakenews, that's it. Sorry.

    Because for a few meters of additional elevation, you'd have to increase the surface by several million square kilometers, and where would we take that surface from? ;-)

      First, I reckon that not all the Earth surface will need elevating - perhaps only Greenland and Antarctica would do? Ok, maybe the Arctic Ocean too
      Second, I have this wonderful idea - how about instead raising soil, we acrually raise some glaciers. I mean, look, 'ts cheaper and will keep us cool.

        raise some glaciers.

        I've got a couple in the storeroom I'm not using.

        They are in pretty good condition, and I can give you a good price for them. Just give me a chance to get in there to find them.

          It took more than long enough just to raise some sons. I'm not signing on for raising glaciers. You guys are on your own.

      Landfills. But more specifically, AOL floppy disks. These were once part of AOL's "pave the earth" campaign to sink the continental US below sea level.

        Actually, if you put all the AOL CDs on roofs reflecting the sunlight away, you'd probably drop the local temperature by a few degrees.

            There are many good CD sander-polisher tools [grainger.com] to help keep your CDs in excellent condition so they are shiny and easy to read.

    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).

    I suspect this is a troll question, but it triggered the What [xkcd.com] If [xkcd.com] XKCD [xkcd.com] series in my mind, so let me take a gander.

    We don't because of several reasons:
    1) It'd be extremely hard to do. It would take an infeasible amount of energy to move that much soil around to lift any appreciable amount of area up. Likewise, the social chaos (and maybe infrastructure and crop failure) displacement would be crazy. Think of how much disruption is caused when trying to move a bridge under on a busy highway, and that's just one piece of limited use area, not an entire city or farmland.
    2) It would cause other issues it would not address, or even make worse. For example, there would be unknown impacts to rainfall (and thus crop harvests). Radiation from could be worse due to less atmosphere between us and the Sun.

      We could get the required energy by slowing the rotation of the earth.
