1) Added table of contents
2) Reorganized "glacier retreat"
3) Added recent TIME article on climate and viticulture

Last but not least: I don't like there's no space between the sections. **How to add space?** I managed to draw a line after each section, but looks kind of ugly.

Here's my general problem with the wiki: **Is there any complete and useable syntax list?** (Useable means: Where you don't need to read lots of blah possibly ending up with nothing.) There are extremely simple questions not answered (how to add space) and I see lots of mysterious syntax in articles that has no explanation I could find anywhere.
