Hatred of knowledge, ignorance, & fear

~
Instead of hatred of knowledge, ignorance & fear, honest concerned citizens should try science, reason, & civility.

And educate themselves about the science & dangers of carbon emissions from coal & oil.

How much carbon dioxide (CO2) is produced when different fuels are burned?

Pounds of CO2 emitted per million Btu of energy:
  • Coal (anthracite) - 227
  • Coal (bituminous) - 205
  • Coal (lignite) - 215
  • Coal (sub-bituminous) - 213
  • Diesel fuel & heating oil - 161
  • Gasoline - 156
  • Propane - 139
  • Natural gas - 117
What are the largest sources of energy-related carbon dioxide emissions by fuel?

United States (Million Metric Tons):
  • Total From Fossil Fuels - 5,833
  • Coal - 2,125 - 36%
  • Natural Gas - 1,272 - 22%
  • Petroleum - 2,436 - 42%
How much CO2 does the United States emit?

Metric tons of carbon dioxide emitted per capita in 2008:
  • United States — 19.2
  • China — 4.9
  • Europe — 7.8
  • World Average — 4.5
What are greenhouse gases and how do they affect the climate?
  • Carbon dioxide (82.8%)
  • Methane (10.5%)
  • Nitrous oxide (4.3%)
  • Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (collectively 2.5%)
These gases are transparent to incoming solar (short-wave) radiation but block infrared (long-wave) radiation from leaving Earth's atmosphere. Therefore, they trap radiation from the Sun and warm the planet's surface. As concentrations of these gases increase, more warming occurs than would happen naturally.
