Everyday on the CitizenTube channel (and @CitizenTube on Twitter), along with our curation partners @storyful, we look at how the top news stories are covered on YouTube. Each week we post a weekly recap of the top news stories of the week, as seen through the lens of both citizen-reported footage and professional news coverage.

Come back next week to see the news unfold on YouTube.

Olivia Ma, YouTube News and Politics, recently watched "New Worry on Global Warming: Mass Shrinkage".
