Saudi Arabia, the world's leading exporter of oil, has become the biggest obstacle to an agreement to fight global warming at the United Nations climate summit in Dubai, where countries are debating whether to call for a phaseout of fossil fuels, negotiators and observers said.
To be sure, Saudi Arabia isn't the only country raising concerns about more ambitious global efforts to fight climate change. The United States has sought to inject caveats into the fossil fuel phaseout language. India and China have opposed language that would single out coal, the most polluting of fossil fuels. Iran and Russia have pushed for provisions to protect natural gas. And many nations, such as Iraq, have raised concerns that ending oil and gas could devastate countries that depend on fossil fuels for income and have asked for more financial support from wealthier countries.
