Not that different from the weather report when you think about it...
Today, maximum temperature in Rio de Janeiro was 21° Celsius, with an average humidity of about 5%. Brazilian geometrists nearing retirement suspect the latest economic development in Costa Rica was the main cause for this phenomenon. ^_^
Indeed. Southern Brazil is just now feebly coming out of a bad dry spell, with all the dams that supply the São Paulo region already below their official "empty" level. Allegedly is has to do with El Niño, a quasi-periodic oscillation of winds and ocean currents over the Southern Pacific. Because of our drought, maize and soybean are up 10% at the Chicago commodities market.
