It's important that your significant other makes you laugh. Mine does.

Tonight's gem?

We were watching TV and a commercial for Chilean produce came on. Something to the effect that it is summer in Chile right now, so enjoy the produce.

Bryan asks "It's summer in Chile right now? Wow, I thought that was only in Australia."

I don't think he was paying attention when the equator and the earth's hemispheres were being explained in geography class.

So, honey, just for you:

Climates in the southern hemisphere overall tend to be slightly milder than those in the northern hemisphere except in the Antarctic which is colder than the Arctic. This is because the southern hemisphere has significantly more ocean and less land. Water heats up and cools down more slowly than land. The southern hemisphere is also significantly less polluted than the northern hemisphere because of lower overall population densities (a total of 10 to 12% of the human population), lower levels of industrialisation, and smaller land masses (air currents run mostly west–east so pollution does not easily spread north or south).

In the southern hemisphere the sun passes from east to west through the north, although north of the tropic of Capricorn the Mean sun can be directly overhead or due south at midday. The sun rotating through the north causes an apparent right-left trajectory through the sky unlike the left-right motion of the sun when seen from the northern hemisphere as it passes through the southern sky. Sun-cast shadows turn anticlockwise through the day (sun dials have the hours in reverse). Hurricanes and tropical storms spin clockwise in the southern hemisphere (as opposed to counter-clockwise in the northern hemisphere) due to the Coriolis effect. A fact often missed is that in the southern hemisphere, the Moon appears to be upside-down compared to the view from the northern hemisphere, or, for people in the south, the northerners have an upside-down image of it.

The southern temperate zone, a subsection of the southern hemisphere, is nearly all oceanic. The only countries that lie entirely within this zone are Uruguay, Lesotho and New Zealand. Countries lying partly in the zone are Chile (most of), Argentina (most of), Paraguay, Brazil, Namibia, Botswana, South Africa (most of), Mozambique, Madagascar and Australia.

The south pole is oriented towards the galactic center and this, combined with clearer skies, makes for excellent viewing of the night sky from the southern hemisphere, with brighter and more numerous stars.
