Klima-Zertifikate

CO2-Zertifikate: Nur ein Bruchteil fliesst in Klimaprojekte
Die Firma South Pole verkauft CO2-Zertifikate. Mit diesen können Firmen oder Kon­su­menten Klima­schäden ausgleichen. Doch von den freiwilligen Zahlungen kommt kaum etwas bei Klimaschutz­projekten an.More...

Glacier de Zinal

Sway presentation about The Zinal Glacier<=

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.

It seems a miracle
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...

Tiktok and the climate

A modern smartphone contains a large number of  elements (highlighted in color). Titanium, for example, is used in the manufacture of the SIM card (light blue), and cobalt in the manufacture of the battery (orange). Hydrogen, which is contained in the housing (yellow), was already used in phones of earlier generations (1960 and 1990). Other elements, such as helium, molybdenum and cadmium, which were used in the past, are no longer present in modern smartphones. (translated by DeepL.com)

Wikipedia preview box

We have implemented a new feature - we call it "Wikipedia preview box". Every link to a Wikipedia article automatically gets a nice preview box (summary) which appears on mouseover or a fingertip and is recognizable in the text through a (W). This works on this site and also on dontwastemy.energy (and other websites), former Wikipedia links got the feature automatically.

It's the first version, if you find a bug, have an idea or comment, please get in contact with the teacher.

Try it out:

Lorem ipsum dolor sit amet Wind Pconsetetur, Hitzewelle aliquyam erat, Baklava sed diam voluptua. At vero eos et 全球变暖 accusam et justo duo श्रीनिवास रामानुजन् et ea rebum. Gubergren, المجموعة الشمسية. Lorem ipsum dolor sit amet, Ada Lovelace Eonsetetur sadipscing elitr, Благовещенск sed diam.

Rábano ipsum dolor Radieschen, consectetur  elit. Sed radish do eiusmod tempor radish ut 萝卜 et dolore magna retiisi. Ut enim ad minim Редис, quis nostrud exercitation ullamco laboris nisi ut aliquip ex eatim ラディッシュ consequat.

Minimanual: Setting a #nopreview at the end of a link prevents the preview box, e.g.: https://en.wikipedia.org/wiki/Radish#nopreview - see the link "radish" above as an example.

The secret of mathematics
When scientists try to explain our world, they often use a powerful tool: mathematics. But is it a human invention or an all-encompassing logic inherent in the universe? A fascinating journey through the world of mathematics, from Pythagoras to Newton to Einstein.
