Late Titicaca, which spans Peru and Bolivia, is increasingly threatened by climate change.

Lake Titicaca, spanning the border between Peru and Bolivia, is critical to supporting the livelihoods of 3 million people. That makes it all the more alarming that this year it was named the “Threatened Lake of the Year” by the Global Nature Fund and the Living Lakes Network, for the second time in just 11 years.

Houthi supporters in Yemen.

For the past year, Yemen has been in a state of limbo, its messy, regionalized conflict on hold but unresolved. And that’s unlikely to change—for the better, at least—soon.

In fact, the mission has several features that ought to reassure skeptics. Whether it can live up to its full potential will depend on a number of factors yet to be determined.

The UN recently approved a mission to Haiti, led by Kenya, to combat gang violence.

Last week, after months of requests from Haiti for international assistance, the U.N. Security Council authorized a peacekeeping mission to fight gangs that have taken over the country’s capital.
