One of the biggest surprises of President Barack Obama's inaugural address on Monday was how much he focused on fighting climate change, spending more time on that issue than any other.

"We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," Obama said.

The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nation's economic future on responding to a changing climate.

"We cannot cede to other nations the technology that will power new jobs and new industries—we must claim its promise," Obama said. "That's how we will maintain our economic vitality and our national treasure—our forests and waterways; our croplands and snowcapped peaks. That is how we will preserve our planet, commanded to our care by God."

So what could the President reasonably do to deliver on that vow? National Geographic asked experts in climate research, energy innovation, and oceanography. Here are ten of their suggestions:

1. Sunset coal with new incentives and regulations. "Provide incentives to phase out the oldest, most polluting power plants," said Robert Jackson, a climate scientist at Duke University. It's already happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Duke's Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean Air Act authority to promulgate carbon regulations for existing power plants like it has for new ones: "Doing that will force fuel switching from coal to natural gas." (Related: "6 Ways Climate Change Will Affect You.")

2. Invest federal stimulus money in nuclear power. It's hardly a perfect fuel, as accidents like Japan's Fukushima fallout have shown, but with safety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporters say. "Nuclear is the only short- to medium-term way to really get away from fossil fuels," said Peter Raven, president emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will far exceed the damage done by faults in the nuclear system.

3. Kill the Keystone pipeline. The controversial Keystone XL oil pipeline is up for review again by the White House this year. "The first thing he should do to set the tone to a lower carbon economy is to reject the Keystone pipeline," said Raymond Pierrehumbert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierrehumbert and some other environmentalists say that by killing it the President would send a clear message about America's intent to ramp down fossil fuels. (See pictures of the animals that helped kill the Keystone pipeline.)

4. Protect the oceans by executive order. Land use is complicated, but large swaths of oceans can be protected by executive fiat. Just as President George W. Bush designated the world's largest marine monument northwest of Hawaii 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 won't stop climate change, but they can give marine species a better chance of adapting to it by reducing the other man-made threats the animals face. (Read about the many benefits of marine reserves.)

5. Experiment with capturing carbon. Huge untapped reserves of natural gas and oil make it unlikely that the U.S. will transition away from fossil fuels in the immediate future. Instead, said Wallace Broecker, geology professor at Columbia University's Lamont-Doherty Earth Observatory, we should attack the atmosphere's carbon surplus directly. "[Obama] could make available funds to build and test prototype air capture units" to capture and store CO2, said Broecker. Removing some carbon from the atmosphere could buy valuable time as policy makers and scientists explore more permanent solutions.

6. Grow government research for new energy sources. The Department of Energy has a nimble program that's tasked with innovative energy research—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 officials requested at least $75 million more. Increasing funding for ARPA-E, said Rafe Pomerance, former deputy assistant secretary of state for environment and development and currently an environmental consultant, "you get new technologies that undercut coal, oil, and gas." Plus, he said, you get a competitive advantage if American researchers uncover the next big idea in new energy.

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

8. Dial back the federal government's energy use. With more than 1.8 million employees, $500 billion in annual purchasing power, and 500,000 buildings to operate, the federal government has been a leader in reducing energy use since Obama signed a 2009 executive order to cut waste. "I would urge him to keep using the power of government to promote energy conservation," said Syndonia Bret-Harte, an Arctic biologist who studies climate change at the University of Alaska, Fairbanks.

9. Build a scientific clearinghouse for climate information. "I advocate for building a better information system on what is happening and why," said Kevin Trenberth, head of the Climate Analysis Section at the U.S. National Center for Atmospheric Research. That involves compiling observations related to climate change from around the world and using the data to refine climate modeling. Think of it as a one-stop, user-friendly website that clearly demonstrates how weather data from around the globe are influenced by broader shifts in the planet's climate.

10. Keep talking. Despite a consensus among top scientists, the world still needs some convincing on climate change. A CNN poll last week found that just 49 percent of Americans agree that global warming is real and is due to human activities. "The most important thing the President can do is to build on his inaugural comments to heighten the sense of urgency about rapid climate destabilization and clarify 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 pulpit to show how a more volatile climate affects everything from agriculture to transportation to 21st-century warfare.

No to Number 2.  I feel that Nuclear as an interim is slow and costly, and huge amounts of C02 is generated just constructing the plants ...

And it relies on a finite resource!! And a dangerous one at that ..... 

Yes to Nuclear Fusion - No to Nuclear fission

The GDP to federal debt ratio is now 101%, having risen from 70% when Obama took office. Once Obamacare is in full swing another $250 billion will be added to the current $1.1 trillion annual deficit. Federal debt is projected to rise from the present $16 trillion to $24 trillion by 2016, bringing the ratio up to 140% in the neighborhood of where Greece is now. No country has ever been able to sustain a viable economy under such conditions. The only way to deal with the debt will be to run the printing presses causing hyperinflation and to tax the middle class because there simply isn't enough tax money to be squeezed out of those evil rich people, both of which will cause further economic stagnation. And Obama has zero plan to deal with the greatest problem we face, which is why he'd rather talk about ammo clips and pipelines.

But, eventuall the math runs over stupidity like a steam roller.

@John C.  ... So where was the call to action during Bush's 8 years of mounting debt? 

Dont lay this solely at the feet of Obama. Many in America can equally hold the blame for every dollar of debt. Cite some more facts from previous decades.

 And the math that eventually runs over simplistic, one-variable macroeconomic math (national debt) is ecological math, which includes the present and future costs of rising food prices, loss of coastal infrastructure, increasing national insecurity and refugees from desertified areas, and a whole host of factors such as the loss of biodiversity, which have ecological value that can only be estimated in dollar terms. Energy costs, especially those related to climate change, constitute a market failure, with unassimilated externalities, unclear and asymmetric information, and the so-called "public goods" problem. So we will have to pay costs eventually, or others will. Besides, suggestions 5, 7, and 8 seem at the very least revenue-neutral, and are probably revenue-positive.

Bush was no winner on fiscal restraint, as Democrats loudly pointed out for eight years.

Oddly, the same Democrats see nothing wrong with Obama running up more debt in four years than Bush did in eight. Go figure.

Obama is a fraud, pure and simple. The most pressing issue our nation faces is economic implosion and he could care less. As long as he can expand his welfare state and Democrat base that goes with it that's all that matters. He's just an inner city machine hack who's now running the country the way Chicago, D.C., California and Detroit have been run into the ground. He's already run up more debt in four years than Bush did in eight, and it will just get worse once Obamacare adds another $250 billion a year to the debt.

Guess who's going to pay for it all? The middle class - you. There's not enough money to squeeze out of the evil rich people, and all the money Obama's printing will slam you with inflation. Its just that boring pne dimensional math again.

Keep worrying about bugs and icebergs as you pay $13 for a gallon of milk in a few years.

@John C. @Mark M. 

It would be to your credit if you would carry on a reasonable conversation without resorting to name-calling, non sequiturs, and other fallacies. The rising price of food--not just for the comparatively affluent American middle class, but for the poor worldwide and for the next generations--is exactly why climate change is so troubling. 

Were we to have a conversation, instead of getting all frothy and high-pitched about Obama, who wasn't even the point, we'd doubtless find areas where we agree that the government can and must cut costs. The real debate, an honest one, is about how the US federal government can respond to the threat of climate change, and if your concern is that we do this without excessive costs to a fragile economy, then which of the suggestions in this article concerns you most? Which seems most economically viable? That's how adults talk. I, for one, like proposal 9 much more than I like proposal 6 because of the costs. 

If, on the other hand, you say "bugs and icebergs" as a clever way to claim that the climate is not changing, or that we ought not to bother addressing it, then you're simply not looking at evidence, and worse, cloaking your ignorance in partisan hysteria.
