Today, Marcy Hersh and I are en route to South Sudan, where we will spend the next three weeks assessing the conditions for displaced people in two of the harshest and most isolated areas of the country. In Jonglei and Unity states, an estimated 180,000 displaced persons are taking shelter in camps, with host families, and hiding in the bush, often with little to no support from the UN or humanitarian agencies.

Crisis after crisis, natural and climate change-related disasters such as floods, droughts, and storms have displaced people from their homes in countries around the world. Though a causal link between any weather event and climate change is difficult to prove, climatologists have long believed that climate change will result in an increase in extreme weather events. Floods, droughts, and storms almost always impact the lives of individuals, forcing them to flee their homes as a result of safety or reduced food supply, among other factors.

A few minutes ago, the United Nations Security Council unanimously approved the creation of an “intervention brigade” within the UN Stabilization Mission in the Democratic Republic of Congo (MONUSCO).

The resolution passed despite a good deal of skepticism on the part of many Council members, and it’s unclear whether the Council is prepared for the potential humanitarian fallout.

After a 20 year absence from Capitol Hill, former Secretary of State George Shultz returned last Friday to urge members of Congress to act on climate change.

Many might find this surprising since Shultz served under President Ronald Reagan and few of his fellow Republicans support action to combat climate change. But it is Shultz’s economic and national security expertise that spurred his case for U.S. leadership on this issue.
