Greenhouse Effects
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).
The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.

A July 1, 2017 New York Times article says that "Chinese corporations are building or planning to build more than 700 new coal plants at home and around the world, some in countries that today burn little or no coal, according to tallies compiled by Urgewald, an environmental group based in Berlin. . . Overall, 1,600 coal plants are planned or under construction in 62 countries. . . The new plants would expand the world’s coal-fired power capacity by 43 percent. . . .Some of the countries targeted for coal-power expansion, like Egypt or Pakistan, currently burn almost no coal, and the new coal plants could set the course of their national energy policies for decades, environmentalists warn."
Obviously, the Chinese do not agree that "the science is settled" or they would not be doing this. Or perhaps they don't care.
Either way, the measures discussed in this article would seem to be futile.
