As the United States is searching for ways to draw down on decades-long wars in Iraq and Afghanistan, serious conflicts might be afoot, one Daily Beast reporter told MSNBC Sunday.

World News editor Christopher Dickey told host Kendis Gibson he doesn't understand the point of barring Iranian diplomats from being able to come to the United Nations General Assembly meeting this fall. During a "Meet the Press" interview Sunday morning, Rep. Liz Cheney (R-WY) said that the U.S. should deny the visas. The statement prompted Sen. Rand Paul (R-KY) to call her out for "warmongering," and said she was out of touch with Americans who don't want to get into another costly Middle East war.

Cities across the United States are already seeing the impacts of climate change. Sea levels are on the rise in Miami, Florida, where ocean waters creep into the streets, even when it isn't raining. Massive wildfires have taken out whole neighborhoods in California and in Alaska, about 2.5 million acres have burned since July 3. Wildfires there are getting worse, according to experts.

The problem of climate change has reached a dangerous level for some homeowners in areas that are no longer insurable. In Miami, for example, the "street-level" is now considered the basement and insurers are dropping coverage for basements. According to the Daily Beast, at least 340,000 California homeowners lost their property insurance coverage between 2015 and 2018 because the wildfires are getting worse and companies don't want to pay out when homes are destroyed.
