[B] "Provide incentives to phase out the oldest, most polluting power plants," said RobertJackson, a climate scientist at Duke University. It's already happening, to some degree, as more ofthe nation transitions to natural gas. Earth scientist Bill Chameides, dean of Duke's Nicholas Schoolof the Environment and a former chief scientist at the Environmental Defense Fund, urges theadministration to use its Clean, Air Act authority to promulgate (頒布 )carbon regulations forexisting power plants like it has for new ones: "Doing that will force fuel switching from coal tonatural gas. "Invest federal stimulus money in nuclear power.

　　[C] It's hardly a perfect fuel, as accidents like Japan's Fukushima fallout have shown, but withsafety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporterssay."Nuclear is the only short-to medium-term way to really get away from fossil fuels," said PeterRaven. President emeritus of the Missouri Botanical Garden. He said the damage done by relentlessglobal warming will far exceed the damage done by faults in the nuclear system.

　　Kill the Keystone pipeline.

　　[D] The controversial Keystone XL oil pipeline is up for review again by the White House thisyear. "The font thing he should do to set the tone to a lower carbon economy is to reject theKeystone pipeline, “said Raymond Pierrehum Bert, a geophysical scientist at the University ofChicago. The pipeline was never going to be a major driver of global emissions, but Pierre humbertand some other environmentalists say that by killing it the President would send a clear messageabout America's intent to ramp down fossil fuels.

　　Protect the oceans by executive order.

　　[E] Land use is complicated, but large swaths of oceans can be protected by executive order.Just as President George W. Bush designated the world's largest marine monument northwest ofHawaii in 2006. Obama could single-handedly protect other areas. National Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U. S.control, putting them off limits to energy production, commercial fishing, and mineral exploration.Marine sanctuaries (禁捕區(qū)) won't stop climate change, but they can give marine species a betterchance of adapting to it by reducing the other man-made threats the animals face.

　　Experiment with capturing carbon.

　　[F] Huge untapped reserves of natural gas and oil make it unlikely that the U. S. willtransition away from fossil fuels in the immediate future. Instead, said Wallace Broecker, geologyprofessor at Columbia University's Lamont-Doherty Earth Observatory, we should attack theatmosphere's carbon surplus directly. "Obama could make available funds to build and testprototype air capture units" to capture and store CO2, said Broecker. Removing some carbonfrom the atmosphere could buy valuable time as policy makers and scientists explore morepermanent solutions.

　　Grow government research for new energy sources.

　　[G] The Department of Energy has a nimble program that's tasked with innovative energyresearch—the Advanced Research Projects Agency-Energy. The ARPA-E funds research in biofuels,transmission,and battery storage, with an annual budget of $ 275 million. Last year, DOE officialsrequested at least $ 75 million more. Increasing funding for ARPA-E, said Rare Pomerance, formerdeputy assistant secretary of state for environment and development and currently anenvironmental consultant, "you get new technologies that undercut coal, oil, and gas. " Plus, hesaid, yon get a competitive advantage if American researchers uncover the next big idea in newenergy.

　　Tax carbon.

　　[H] Congress would have to agree, but many climate experts say that the most meaningful wayto tackle emissions is to set a price on carbon. "We should be asking people to pay the cost ofputting carbon into the atmosphere as they buy the fuel," said Josh Willis, climate scientist andoceanographer at NASA's Jet Propulsion Laboratory. To gain political support for the idea, Obamawould probably have to show that the tax wonld help accelerate technology, grow new industries,and pay down the deficit.

　　Dial back the federal government's energy use.

　　[I] With more than I. 8 million employees, $ 500 billion in annual purchasing power, and500,000 buildings to operate, the federal government has been a leader in reducing energy usesince Obama signed a 2009 executive order to cut waste. "I would urge him to keep using thepower of government to promote energy conservation," said Syndonia Bret-Harte, an Arcticbiologist who studies climate change at the University of Alaska, Fairbanks.

　　Build a scientific clearinghouse for climate information.

　　[J] "I advocate for building a better information system on what is happening and why," saidKevin Tren berth, head of the Climate Analysis Section at the U. S. National Center for AtmosphericResearch. That involves compiling observations related to climate change from around the worldand using the data to refine climate modeling. Think of it as a one-stop, user-friendly website thatclearly demonstrates how weather data from around the globe are influenced by broader shifts inthe planet's climate.

　　Keep talking. Despite a consensus among top scientists, the world still needs some convincingon climate change.

　　[K] A CNN poll last week found that just 49 percent of Americans agree that global warming isreal and is due to human activities. "The most important thing the President can do is to build on hisinaugural comments to heighten the sense of urgency about rapid climate destabilization andclarify its connection to virtually every other issue on the national agenda," said David Orr,environmental studies professor at Oberlin College. That means using the bully clergymen to showhow a more volatile climate affects everything from agriculture to transportation to 21st-centurywarfare.
