A U.S. judge says Argentina must repay hedge funds that own bonds the country had defaulted on in 2001. Argentina has asked for a stay in the ruling. Stephen Nelson, a professor of political science at Northwestern University who specializes in the politics of debt, explains the case.
The science is clear that trees help reduce the effects of Climate Change because they remove carbon dioxide from our atmosphere. For our "EcoMyths" segment, Kate Sackman joins us to talk with Robert Fahey from Morton Arboretum. They want us to know that “treehugging is cool” for us and the environment. Fahey studies forest ecosystems and urban forestry and admits to hugging trees, but clarifies that it's "usually for research purposes."

Cutting down these trees is just one way to get rid of the pest, but it’s not enough. Jerome and Kate Sackman from EcoMyths Alliance talk with two experts about other options and the tree's significance to Chicago.
