Change usually happens at a snail's pace (im Schneckentempo) in Cuba, but new media have rapidly transformed the Caribbean island in recent years. Since Cubans gained free access to the Internet in 2018, censorship has become permeable (Zänsur wurde durchlässig).

Info about the Zinalgletscher (in German)
Located in the canton of Valais, it covers an area of 13.36 km2 and its length is 7.29 km (data from 2010). In 1973, the glacier covered an area of 15.70 km2. The relative area change amounts to -14.90 %.
The Glacier of Zinal was in 2013 just under seven kilometres long, so since 1973 it has receded (sich zurückgzogen/geschmolzen) by a little more than half a kilometre.

The Namib, a coastal desert in Southern Africa. The cold Benguela current causes the cooled down sea air to carry almost no water inland. The endemic species of the Namib have adapted to this situation, e.g. the Welwitschia or "fog beetles".
Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world.More...
