RIO DE JANEIRO, BRAZIL – In the Southern Hemisphere winter is here, taking us by surprise as every change of season in every corner of the globe seems to. In Rio that means nights can cool well into the 60's (Fahrenheit, high-teens in Celsius), and the days in the 70's, and maybe the most dramatic change is the short days, with sunrise at 6AM and sunset around 5PM.
For our readers in the north of the Northern Hemisphere that may sound like a walk in the park, and it is. But still there are no heating systems . . .
