Broke with a tweet from irans president shortly before president obama announced it, rouhani turned down a face to face meeting when both men were in new york on tuesday, but the call was his idea. Rouhani has been in new york all week, speaking at the u. N. And vowing warmer relations with the United States. The obstacles are huge, for years war with iran has seemed more likely than diplomatic progress. The president says he sees a chance for a big change. Beginning with renewed talks on Irans Nuclear program. I believe we have a responsibility to pursue diplomacy, and a unique opportunity to make progress with the new leadership in tehran. Reporter right after the president touted his historic conversation with the president of iran, he lashed out at a group he hasnt been talking to, republicans in congress, who he blamed for putting the government on a path to shutdown in just three days. Nobody gets to threaten the full faith and credit of the United States just to extract political concessions. No one gets to hurt our economy and millions of innocent people just because there are a couple laws you do not like. Reporter history was made with the Obama Rouhani phone conversation, there has been no phone calls this week between the president and the speaker of the house. Diane, it is no exaggeration to say that the president has made more progress this week with iran than he has with republicans in congress. All right. Give us the real story. Is there going to be a shutdown next week . And how long . Reporter i think there quite likely will be, i put the odds at 5050 this morning now there is more likely than not there will be a shutdown next week for a couple days.

Reporter rising heat already costs the average American Family like the rieblers of new jersey in everything from food to airconditioning. But that is nothing says todays report if the world doesnt make big changes soon by the year 2040, we could have released enough greenhouse gases, that we will have locked in a global temporize of 3. 6 degrees.

Were talking about an increase in animal extinction, a drying up of farm land that leads to massive food shortages, and putting us on a path toward sea level rise, that could swallow parts of major American Cities like new york, miami and san diego. Skeptics have predictively accused the u. N. Panel of being alarmist. But this is a major wake up call. Why isnt there a greater sense of urgency out here in the real world about Climate Change .

Reporter so what kind of changes need to be made . How will they affect you .

The first class cabben turned triage, they performed cpr right there on the floor. I saw them working on the captain. It was very impressive, how they worked together. Reporter another planes pilot heard the commotion and radioed in. What was going on with united . A medical emergency, their captain. Thats not good. Reporter at the same time a united pilot sitting among the passengers went to the cockpit to help as the plane made an Emergency Landing in boise, idaho. One of the reasons we have two crew members, the airplane can be flown by either of the pilots, each pilot is fully capable of flying the airplane. Reporter despite everything their captain didnt make it. He was pronounced dead just a few hours later. Passengers feeling lucky to have landed safely, were eventually put on another plane.

Infiniti tells abc news it will Study Results as quote, we continue to develop future technologies. These systems add about 1,000 or more to the cost of the car.
