Heatwaves & Drought
 |
| An extreme heatwave hit Europe in the summer of 2003, when temperatures reached 38.5C (101.4°F). The Eiffel Tower was barely visible as the air around Paris became heavily polluted. More than 30,000 people died throughout Europe in what later became the continent's biggest ever natural disaster. (Photograph: Jack Guez/AFP) |

Sailing Stones
'Sailing Stones' refer to a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention. They have been recorded and studied in a number of places around Racetrack Playa, Death Valley which is situated in the Mojave Desert, eastern California.
The stones move only every two or three years, and the latest study (published in 2011) claims that the movement of the stones is caused by small 'rafts' of ice that form around the rocks at night and this allows them to glide with minimal friction when struck by relatively light winds.
The phenomenon, however, remains the subject of much study.
Death Valley, apart from hosting the 'sailing stones' phenomenon, holds the record for the hottest July temperature ever recorded in the western hemisphere ... 57 degrees C (134 degrees F) on July 10th, 1913.

The Spectacular Caves Of 'E Cavernoso'
Situated deep within the wilds of Southern Brazil, the 'E Cavernoso' caves are regarded as amongst the most spectacular in the world. The following photographs will show you what I mean. They were all originally published by National Geographic, where many more can be found.
