Everytime I search the internet I (as probably everyone else) come across great pages I would not only like to recommend, but remember myself. I also often have pages recommended in class. Thus I will gradually add to this post.
I have turned this post into a page: Great Websites
Every year around 1 000 experts (700 in 2014) from industry, international organizations, government, academia and society are asked to give their assessment of a list of global risks. The results are reported on the WEF webpage, where you can also find the survey itself and graphic analyses of the results.
Here the link to this years WEF report.
