Katharine Hayhoe on why we need to talk about climate change to fight it

In our Ideas That Matter partnership with TED, we highlight individuals and ideas shaping our world. This time we’re taking a closer look at climate change. The latest government climate assessment warns that by 2050, heavier rainfall in the Midwest could prompt increased flooding along major waterways like the Mississippi River. By 2071, temperatures in the southwest could climb more than eight degrees, leading to longer droughts. Climate scientist Katharine Hayhoe, who co-authored the report, joins "CBS This Morning" to discuss why we need to talk about climate change to spur action.
