Woodruff the Obama Administration has essentially cleared the way to allow Royal Dutch Shell to begin drilling for oil and gas in the arctic ocean this summer. Its one of the most consequential and longawaited drilling decisions from the government. Shell is seeking approval to drill in the american portion of the chukchi sea off the coast of alaska. Environmental groups have long warned of the dangers of doing so. Estimates show there may be as much as 22 billion barrels of oil and 93 trillion cubic feet of natural gas in the area. Reporter coral davenport covers this for the New York Times and joins me from its washington bureau. Coral davenport welcome. Help us understand a little better what area were talking about. Exactly where is it, how large is it, what does it look like . Judy, its a very big portion of the arctic ocean. The part theyre looking at where shell leases are about 70 miles off the coast of alaska. It is a pristine untouched area. It is home to has habitats of several rare species large mammals, migrating habitats for whales, feeding habitats for walrus. Its also a very treacherous area extreme storms waves up to 50 feet high, completely frozen over with ice in the winter. So this is a very remote very treacherous, almost completely untouched area. Area. Woodruff so understanding the environmental objections, we know shell has had difficulties in the past with some drilling and similar circumstances. What has shell said its going to do to protect the environment . So this is not the first time the administration has given a go aheadto shell to drill in the area. It gave a permit to shell to explore to see whats in the area. They went in the summer of 2012. They were plagued that whole period with safety problems, operational problems. They had two rigs that we went to ground that had to be towed away. The administration said they would not reissue a permit to shell until they had gone back, assured they would upgrade their safety and operations procedures. In the meantime the administration had also put forth new strilg drilg safety regulations that anyone drilling will have to follow. Environmental groups say despite the promises, assurances and new regulations on the part of the administration, this area is so treacherous to drill and so pristine that they fear that its still an accident waiting to happen. Woodruff well, what else should we know about why the administration has agreed to do this . Oil prices are certainly down, the spree is up. Whats the supply is up. What iswhat the administration saying is the rationale . Well, some of this is build in. These are areas the federallyowned portions of land were sold by the Bush Administration to be drilled, to be leased so shell paid for its lease to drill during the Bush Administration. They applied for a permit to use that lease to go in and drill it. If the Obama Administration had ignored that permit or had, you know just completely denied it, shell absolutely would have sued. If they were to have taken away the permit, they would have to give shell back the money they paid for it, so some of this was just a matter of the Obama Administration had to with what was on its plate. Again, nonetheless, environmental groups are surprised and say could it have found some kind of way not to do this. It really is still a very striking piece of this president s environmental legacy. Woodruff but this does coral davenport, essentially clears the way for this to happen and we understand, this summer, there is not much else that could take place in the meantime in the courts or elsewhere to stop this . Right. To be clear, what the administration gave today was a conditional approval. They cleared the last sort of secondtolast and sort certainly the last major hurdle for shell to move forward. It gave it on condition shell made sure it gets the rest of its local and statelevel permits. The company said its moving forward with doing that. That will be the absolute final. But people ive talked to said this is 95 of the way theyre and the big piece everyone was waiting for to see which way it would go is the decision by the Obama Administration. Woodruff a story everyone is watching. Coral davenport with the New York Times. Thank you. Thanks so much judy. Ifill fighting raged across yemen today on land and in the air, in the countdown to a ceasefire. In recent weeks, more than 1,400 people have been killed, and 150,000 forced to flee, in whats become a proxy war between saudi arabia and iran. Chief Foreign Affairs correspondent Margaret Warner begins our coverage. Warner hours before the truce was to begin, saudi Armored Vehicles moved toward the border, after clashing with yemens shiite houthi rebels. There was no indication that any ground assault was imminent. Meanwhile, a Houthi Television channel showed the apparent wreckage of a moroccan f16 fighter jet, part of the saudi aerial coalition. The houthis said they shot it down, and showed what was purported to be the pilots i. D. Card. Still, the bombing continued with reports of a major Coalition Air strike on a weapons depot in yemens capital, sanaa. Marieelisabeth ingres of Doctors Without Borders is in sanaa, and says conditions are growing ever more dire. Warner the same is true in the port city of aden, where heavy street fighting raged today between houthis and loyalists of president Abdrabbu Mansour hadi, now in exile in saudi arabia. translated we are living under siege, surrounded by these houthis; no water, no electricity, the sewage is overflowing, our childrens bellies are swollen and we have no medicine, we have nothing. Warner all this came as the clock ran down toward a fiveday humanitarian ceasefire between the Saudiled Coalition and the houthis, who have some backing from iran. On saturday, iranian president Hassan Rouhani blasted the saudis in a speech. translated saudi arabia is a government that does not understand and is not aware of the political situation of the region and the world and is a total beginner. It is trying hard to prove itself after many years. Warner the new saudi king, salman, has shown a more aggressive regional stance during his four months on the throne. And the efforts of the sunni powers in the region, led by the saudis, to counter shiite iran will be a top issue this week at a gulf nation summit hosted by president obama. Also on that agenda the u. S. Led talks with iran on its nuclear program; the syrian civil war; and the Ongoing Campaign against the Islamic State group. Last thursday, king salman had told secretary of state kerry that he would attend. But over the weekend, salman and the king of bahrain said they would not be on hand, sending other officials in their place. That left state Department Spokesperson marie harf today to deny its a snub of mr. Obama, triggered by saudi concerns over the president s pursuit of a nuclear deal with iran. King salman made this decision given whats going on in yemen. Hes sending the crown prince and the deputy crown prince who are fully empowered. They run intel, they run defense, they run a lot of the areas that were actually going to be talking about in detail at camp david. So we believe that the right mix of people will be there. Warner right mix or not, the meetings begin wednesday at the white house before moving to camp david. Ifill and margaret joins me now. Ifill margaret we saw at the state department and also the white house in the Briefing Room today an aggressive pushback this notion was a snub the lastminute decision not to come on the part of the saudi king. What really happened . When this was laid on by the white house last month right after coming up with this political framework for an Iranian Nuclear deal the hope was with the right assurances the gulf countries would at least give some sort of tacet approval to pursuing this deal. Instead, what the white house felt was a great compliment being invited to the white house, camp david, im told by peopleo close to the palace in saudi arabia that the king felt he was being summoned to washington, he didnt like being lumped in with all the gcc members, and vacked should and saudi arabia should be first among equals, and became apparent he wasnt going to get the assurances he wanted. Being from a culture where its rude to your host to say no he didnt want to be taken up to camp david and asked to sign something that he later would want to back off from. Ifill the president talked to him today to smooth things over, we seem. Yes. Ifill but at the root of this, iran. Ifill yes, and the fact that the u. S. And saudis over a partnership with oil and other things really dont understand each other very well, but, yes, its not only that iran after ten or 15 years, whenever the negotiated time period expires that iran could be a nuclear weaponscapable state saudis fear that once the International Community strikes a deal with iran, iran will, one gain stature and legitimacy and maybe sur plant the u. S. As a part in the region and once sanctions are lifted it will even be better able to funneled a lot of the groups, proxies destabilizing countries in the region whether the shiite in bahrain, hezbollah blah in syria or the houthis in yemen. Ifill talk late bit about yemen because i wonder if thats also on part of the agenda. Is there anything that can be accomplished at this meeting in camp david . I think what the saweddias or certainly the uae wanted was a defense pact almost like n. A. T. O. And the americans told them a couple of weeks ago that wasnt going to happen. But the u. S. Is talking about not only selling them more weapons but also helping the gcc develop greater capabilities to defend against unconventional threats, whether cyber, threats to the own Oil Infrastructure and make it interoperable with the u. S. And there will be some document that reaffirms the u. S. Commitment to the security of its allies. For instance, when Saddam Hussein invaded kuwait, the u. S. Was in there. One person close to the saudi culture said dont undere
