After spending some time bringing together Israel and Palestine for a handshake photo-op in New York, President Obama turned his attention to a problem that may prove equally daunting: global cooperation on climate change.

In his first UN appearance since taking the Oval Office, Obama staked a lofty position for the US, promised that the US is “determined to act,” and that the US “will meet our responsibility to future generations.” Chinese President Hu Jintao matched Obama’s rhetoric, pledging that the Chinese would commit to a host of progressive steps around renewable energy and emissions reductions, but also cautioning that developing economies like China’s “should not … be asked to take on obligations that go beyond their development stage.”

The summer saw a lot of pre-positioning in advance of Copenhagen, and with today’s UN General Assembly marking the beginning of a series of mini-summits in the lead-up to December’s big climate change conference, the volume on those announcements will only increase along with their frequency and grandeur.

Still, with Obama facing an uphill battle on domestic climate change legislation and China hiding behind their “developing” status, Copenhagen is threatening to become little more than a public relations event with little real concerted action. The US will have to avoid making the push for global leadership on climate change into a new breed of arms race that would find Obama and US policymakers at a significant disadvantage against the Chinese in the following ways:

Paying Lip Service is Costly – China, India and other developing countries want the US-led West to subsidize their carbon reduction efforts. If the West balks and no comprehensive global agreement emerges, the US could still find itself saddled with costly commitments made in going toe-to-toe with China as a demonstration of leadership and willingness to cooperate. For example, at the UN, President Jintao made the headline-grabbing promise to plant enough new trees in China to cover the area of Norway. Jintao also promised to get China to 15% renewable energy within 10 years, a much more ambitious timeline than any US plan. While it may not represent the kind of economy-crippling commitment that China fears will result from a global agreement, these programs will be costly, and Obama has his hands full just trying to pay for health care.

Democracy’s Dilemma - Not only is Obama hamstrung by health care, an increasingly troublesome war in Afghanistan, and an economy that is still teetering; but, he also has the mettlesome matters of bipartisanship, political pressure and budget restraints. While a strongly Democratic House could barely pass a weakened climate bill, Jintao and the Chinese have a one-party system overseeing a command economy that gives the Chinese a lot more adaptability as circumstances dictate in Copenhagen, in the world press, and on the geopolitical landscape.

The World Won’t Grade on a Curve - The Chinese are already crying foul over efforts to stifle their economy for the sake of climate change action and the world community is not expecting much from the world’s fastest growing economy and most voluminous emitter. Commitments like those above are enough to make a splash and convince the world that China really is trying. By contrast, Senators from Obama’s own party are refusing to discuss the prospect of domestic climate change legislation unless it includes trade protections. That kind of opposition in his own party makes a lot of his words ring hollow while the Chinese will certainly be able to deliver on whatever proposals they float. There are no handicaps in this game, so even if they overshoot on a much lower standard, the Chinese promise to steal Obama’s thunder.

Conventional wisdom says you should never enter a land war in Asia. The same might be said for wars of words.
