It's become something of a clich in energy-policy discussions: The United States is making headway on global warming and slashing its carbon-dioxide emissions all because of a glut of cheap natural gas that's elbowing out dirty coal power.

Emissions continue to grow so rapidly that an international goal of limiting the warming of the planet to 3.6 degrees is on the verge of becoming unattainable, researchers said.

Carbon dioxide emissions hit an unexpected 20-year low earlier this year, mainly because utilities have switched from coal to natural gas.

New research provides compelling evidence that the last ice age was ended by a rise in temperature driven by an increase in atmospheric carbon dioxide.

Global emissions of carbon dioxide from fossil-fuel burning jumped by 5.9 percent, upending the notion that the brief decline during the recession might persist.

The Obama administration finalized new environmental rules for automobiles Thursday that officials say will spur new vehicle technologies and reduce oil consumption. The rules require that all new cars average about 35.5 miles per gallon by ...

Urban visionaries in London and Seoul, two of the world's busiest capital cities, foresee buses gliding through their streets with speed, ease and efficiency - without emitting the exhaust fumes that scientists say are contributing to global warming. Under Mayor Boris Johnson's vision, London's iconic red double-decker Routemaster buses would be back on the streets - but powered by electricity, not gasoline.

Deforestation is blamed for 20 percent of harmful carbon dioxide emissions and the extinction of thousands of unique species of plants, animals and insects. The issue means nothing less than survival in Panama, where ranchers and tribesmen are at odds over a dwindling rainforest.
