The melting "mirrors" the worldwide increase in temperature and is from the burning of coal, oil and gas.

融化“反映”了全球温度的上升，这是由煤炭、石油和天然气的消耗造成的。

While fossil fuels—coal, oil, gas—still generate roughly 85 percent of the world's energy supply, it's clearer than ever that future belongs to renewable sources such as wind and solar.

虽然化石燃料——煤炭、石油、天然气——仍占世界能源供应的大约85%，但比以往任何时候都更清楚的是，未来属于可再生能源，如风能和太阳能。

The more we reduce our use of coal, oil, and gas and the more we increase energy independency, the less we risk fights over energy and resources.

我们越多削减煤炭、石油和天然气的使用，越能增加能源的独立性，由能源和资源引起冲突的风险越小。

Greenhouse gas emissions, such as carbon dioxide, are created in part by burning oil and coal for transportation and electricity.

Automobiles create it. Any device that burns fuels like coal,gasoline,kerosene, oil or wood will produce carbon monoxide.

Any device that burns fuels such as coal,oil or wood can create the gas.

It produces less carbon dioxide for a unit of energy than coal or oil, so the climate will benefit to the degree that gas replaces either of those: it will mostly substitute for coal, though some oil too, especially if gas-powered trucking becomes widespread.

ECONOMIST: Natural gas

For their calculations, the two assumed that where there was a gap between demand and conventional supply it would be filled with synthetic fuels, first with tar-sands oil and later with oil from coal and shale. (According to high-end estimates, coal and oil shale could together yield some ten trillion barrels of unconventional crude.) They then calculated what the impact would be on global carbon-dioxide levels.

NEWYORKER: Unconventional Crude

While conspiracy theorists may want to believe that Big Oil, Big Coal and Big Nuclear are stifling the growth of renewables, the simple truth is that coal, oil, natural gas and nuclear can satisfy the Four Imperatives: power density, energy density, cost and scale.
