NEW YORK (CNNMoney.com) -- U.S. President Barack Obama set his green plan into action Monday, potentially reversing several Bush-era decisions on global warming and fuel efficiency. U.S. President Barack Obama signs orders Monday on vehicle emissions and fuel efficiency standards. In his first major environmental acts as president, Obama directed his Environmental Protection Agency to review a California application to regulate greenhouse gases and told his Department of Transportation to begin implementing fuel efficiency standards passed last year but not implemented by the Bush administration. He also pushed for passage of the $825 billion economic stimulus package in the House and Senate. Those bills include money for investments in renewable energy, conservation and a better electric grid.Obama orders review of California request to regulate greenhouse gasesU.S. president orders government to implement fuel efficiency standardsAutomakers oppose plan as an expensive patchwork of lawsFormer President George W.

(CNN) In 2004, Mostafa Salameh had a vivid dream: he was praying for peace on the top of a mountain. "I woke up sweating and I saw myself on top of the world," Salameh tells CNN. Back then, Salameh had no expedition experience, little money and couldn't have pointed to Mount Everest on a map. Fast forward to 2017, and he has become the first Jordanian to complete the "Explorers Grand Slam," which entails climbing the Seven Summits, including Mount Everest, and reaching the North and South poles. Only 15 other people have ever achieved the Grand Slam. His amazing life has now become the subject of an international book, published by Bloomsbury and endorsed by King Abdullah II of Jordan and British adventurer Ranulph Fiennes.Mostafa Salameh has become the first Jordanian to climb the Seven Summits, and trek to both the North and South polesHe has released a book "Dreams of a Refugee: From the Middle East to Mount Everest" detailing his adventures

(CNN) -- Can presidential candidates talk to voters like adults? Will voters support a candidate who tells them the truth? The answer to that question is obvious to anyone who has observed American politics in recent years. One day -- let us hope it comes soon -- voters will demand that their political leaders present them with a more realistic sense of the possibilities and choices they face. But for now, voters demand perfect odds and simple solutions, and politicians oblige. President Obama confessed as much in a recent Vanity Fair profile, when he revealed he knows that each one of the decisions he makes as president could turn out wrong. "Nothing comes to my desk that is perfectly solvable," he said. "Any given decision you make you'll wind up with a 30 to 40 percent chance that it isn't going to work." But the American public, the president suggested, cannot handle those odds. After you have made your decision, you need to feign total certainty about it.Frida Ghitis asks, Will voters support a presidential candidate who tells the truth?Ghitis: The answer is obvious; voters demand perfect odds and simple solutionsShe says Obama recently said he has to feign total certainty in his decisionsGhitis: True charisma and leadership require acknowledging uncertainties 
 Question:But beneath the wishful thinking, _ know that the world is complicated, the economy is challenging, the choices difficult.
