Simply heating the iron directly leaves the resulting alloy with a very high carbon content, often 4 to 5%.

It seems less likely that a majority of voters would vote for such a high carbon tax today.

The higher carbon dioxide concentrations trap solar energy.

Metal also has higher embedded carbon than other materials, so you should remember this if your business is looking to reduce its carbon footprint.

"Give him a higher carbon dioxide atmosphere."

I can tell you high carbon, low carbon, how much nickel or manganese.

A study using loblolly pines showed that higher atmospheric carbon dioxide levels may help the trees to endure ice storms better.

Oils have a high carbon and hydrogen content and are usually flammable and slippery.

The steel used is generally a high carbon variety and very hard.

Gas chick incubators are wasteful - a high carbon footprint.
