Mr Obama's plan to curb carbon dioxide (CO2) emissions (排放), though necessary, will be far from cost-free, whatever his sunny speeches on the subject might suggest.

According to the author, Obama's plan to limit carbon dioxide emissions will by no means be inexpensive

The result would be higher emissions of carbon dioxide and other greenhouse gases.

Left alone, it was assumed, the world's rain forests would not only flourish but might even rescue us from disaster by absorbing the excess carbon dioxide and other planet-warming greenhouse gases.

For a start, all animals, such as cows, pigs and sheep, always gas limed methane, which is the second most common green house gas after carbon dioxide.

Many environmental experts now believe that methane is more responsible for global warming than carbon dioxide

But its surface has been cooked and dried by an ocean of carbon dioxide, trapped in the burning death grip of a runaway greenhouse effect.

Heating this chemical compound drives off carbon dioxide gas, leaving calcium oxide.
