The dreaded El Niño strikes the globe every 2 to 7 years. As warm waters in the tropical Pacific Ocean shift eastward and trade winds weaken, the weather pattern ripples through the atmosphere, causing drought in southern Africa, wildfires in South America, and flooding on North America's Pacific coast. Climate scientists have struggled to predict El Niño events more than 1 year in advance, but artificial intelligence (AI) can now extend forecasts to 18 months, according to a new study. The work could help people in threatened regions better prepare for droughts and floods, for example by choosing which crops to plant, says William Hsieh, a retired climate scientist in Victoria, Canada, who worked on early El Niño forecasts but who was not involved in the current study. Longer forecasts could have "large economic benefits," he says.

Artificial intelligence is learning how to predict El Niño climate cycles. The hope is that the technology could be used to improve climate predictions and give policy-makers more time to prepare. El Niño can cause severe weather and devastating damage. A phase of the El Niño-Southern Oscillation, it occurs when water warms over the tropical Pacific Ocean, shifting east and increasing rainfall and cyclones over the Americas while pulling rain away from Indonesia and Australia. Strong El Niño events are associated with intense storms and flooding in some areas, and drought and fires in others.

RIYADH – Saudi Arabia alleged Wednesday an attack by drones and cruise missiles on the heart of the kingdom's oil industry was "unquestionably sponsored by Iran," naming but not directly accusing Tehran of launching the assault. Iran denies being involved in the attack claimed by Yemeni rebels, and has threatened the U.S. that it will retaliate "immediately" if Tehran is targeted in response. The news conference by Saudi military spokesman Col. Turki al-Malki comes after a summer of heightened tensions between Iran and the U.S. over President Donald Trump unilaterally withdrawing America from Tehran's 2015 nuclear deal with world powers. The U.S. alleges Iran launched the attack, which Yemen's Houthi rebels earlier claimed as a response to the yearslong Saudi-led war there that's killed tens of thousands of people. Al-Malki made a point not to directly accuse Iran of firing the weapons or launching them from inside of Iranian territory.

DUBAI, UNITED ARAB EMIRATES – The assault on the beating heart of Saudi Arabia's vast oil empire follows a new and dangerous pattern that's emerged across the Persian Gulf this summer of precise attacks that leave few obvious clues as to who launched them. Beginning in May with the still-unclaimed explosions that damaged oil tankers near the Strait of Hormuz, the region has seen its energy infrastructure repeatedly targeted. Those attacks culminated with Saturday's assault on the world's biggest oil processor in eastern Saudi Arabia, which halved the oil-rich kingdom's production and caused energy prices to spike. Some strikes have been claimed by Yemen's Houthi rebels, who have been battling a Saudi-led coalition in the Arab world's poorest country since 2015. Their rapidly increasing sophistication fuels suspicion among experts and analysts however that Iran may be orchestrating them -- or perhaps even carrying them out itself as the U.S. alleges in the case of Saturday's attack.

Democratic Congresswoman Ilhan Omar faces condemnation over her'some people did something' comments; reaction from Fox News contributor Ari Fleischer, former White House contributor. Rep. Ilhan Omar, D-Minn, blasted President Trump over his handling of Iran and suggested that his administration is to blame over the increased tensions between the two nations. Over the weekend, Iran-backed Houthi rebels claimed they launched drone attacks on the world's largest oil processing facility in Saudi Arabia and a major oil field Saturday, sparking huge fires and halting about half of the supplies from the world's largest exporter of oil. The attacks marked the latest of many drone assaults on the Kingdom's oil infrastructure in recent weeks, but easily the most damaging. They raised concerns about the global oil supply and could further escalate tensions across the Persian Gulf amid a growing crisis between the U.S. and Iran over the troubled nuclear deal.

DUBAI, UNITED ARAB EMIRATES – A weekend drone attack on Saudi Arabia that cut into global energy supplies and halved the kingdom's oil production threatened Sunday to fuel a regional crisis, as Iran denied U.S. allegations it launched the assault and tensions remained high over Tehran's collapsing nuclear deal. Iran called the U.S. claims "maximum lies," while a commander in its paramilitary Revolutionary Guard reiterated its forces could strike U.S. military bases across the Mideast with their arsenal of ballistic missiles. A prominent U.S. senator suggested striking Iranian oil refineries in response to the assault, claimed by Yemen's Iran-backed Houthi rebels, on Saudi Arabia's largest oil processing facility. "Because of the tension and sensitive situation, our region is like a powder keg," warned Guard Brig. "When these contacts come too close, when forces come into contact with one another, it is possible a conflict happens because of a misunderstanding."

Drone attacks claimed by Yemen's Houthi rebels struck two key oil installations inside Saudi Arabia on Saturday, damaging facilities that process the vast majority of the country's crude output and raising the risk of a disruption in world oil supplies. The attacks immediately escalated tensions in the Persian Gulf amid a standoff between the United States and Iran, even as key questions remained unanswered -- where the drones were launched from, and how the Houthis managed to hit facilities deep in Saudi territory, some 500 miles from Yemeni soil. Secretary of State Mike Pompeo accused Iran of being behind what he called "an unprecedented attack on the world's energy supply" and asserted that there was "no evidence the attacks came from Yemen." He did not, however, specify an alternative launch site, and the Saudis themselves refrained from pointing the finger directly at Iran. President Trump condemned the attack in a phone call with Saudi Crown Prince Mohammed bin Salman and offered support for "Saudi Arabia's self defense," the White House said in a statement, adding that the United States "remains committed to ensuring global oil markets are stable and well supplied."

Saudi authorities attempt to control a fire at an Aramco factory. The world's largest oil processing facility and a nearby oil field in Saudi Arabia were set ablaze early Saturday morning after reported drone attacks by Iranian-backed Yemeni rebels. The Interior Ministry was quoted by state-run media as saying the fires at the Abqaiq oil processing facility in Buqyaq and the nearby Khurais oil field operated by Saudi Aramco were "targeted by drones." It wasn't immediately clear if there were any injuries, nor what effect it would have on oil production in the kingdom. Smoke is seen following a fire at Aramco facility in the eastern city of Abqaiq, Saudi Arabia, September 14, 2019.

DUBAI, UNITED ARAB EMIRATES – Drones attacked the world's largest oil processing facility in Saudi Arabia and a major oil field operated by Saudi Aramco early Saturday, the kingdom's Interior Ministry said, sparking a huge fire at a processor crucial to global energy supplies. No one immediately claimed responsibility for the attacks in Buqyaq and the Khurais oil field, though Yemen's Houthi rebels previously launched drone assaults deep inside of the kingdom. It wasn't clear if there were any injuries in the attacks, nor what effect it would have on oil production in the kingdom. The attack also likely will heighten tensions further across the wider Persian Gulf amid a confrontation between the U.S. and Iran over its unraveling nuclear deal with world powers. Online videos apparently shot in Buqyaq included the sound of gunfire in the background.

Squeezing a house through a nozzle, like a pâtissier pumping fondant cream from a piping bag, may not be everyone's idea of cutting-edge construction. The glitzy emirate aspires to have a quarter of all new buildings constructed via 3D printing by 2030. Emaar, one of the Arabian Gulf's leading property developers, is heralding its nascent Arabian Ranches III residential project as offering Dubai's first such dwelling. Fabricating a three-dimensional model, or prototype, from a computer-aided design by adding successive layers of material is now standard practice in many industries, ranging from aerospace and architecture to medicine and high-end manufacturing. McKinsey, the consultancy, estimates the technique could have an annual economic impact worth $550 billion by 2025.
