Talking Points on Climate Change: Science, Economics, and More

Scientific Evidence

1—Carbon dioxide is not a pollutant. On the contrary, it makes crops and forests grow faster.
Mapping by satellite shows the Earth has become about 6 percent greener overall in the past two
decades, with forests expanding into arid regions. The Amazon rainforest was the biggest gainer,
with two tons of additional biomass per acre per year. Certainly climate change does not help
every region equally, but careful studies predict overall benefit, fewer storms, more rain, better
crop yields, longer growing seasons, milder winters, and decreasing heating costs in colder
climates. The news is certainly not bad and on balance may be rather good.

2—Someday the world will wake up and laugh when people finally understand that the entire
pursuit of economic ruin in the name of saving the planet from increasing carbon dioxide is in
fact a terrible joke. You see it is an inarguable fact that the portion of the Earth’s greenhouse gas
envelope contributed by man is barely one-tenth of one percent of the total. Do the math
yourself: CO2 is no more than 4 percent of the total (with water vapor being more than
90 percent, followed by methane and sulfur and nitrous oxides). Of that 4 percent, man
contributes only a little more than 3 percent. Elementary school arithmetic says that 3 percent of
4 percent is .12 percent, and for that we are sentencing the planet to an array of damaging
economic impacts.

3—The effect of additional CO2 in the atmosphere is limited because it absorbs only certain
wavelengths of radiant energy. As the radiation in the particular wavelength band is used up, the
amount left for absorption by more of the gas is reduced. A simple analogy is to consider
drawing a curtain across a window—a large part of the light will be shut out, but some will still
get through. Add a second curtain to the first and most of the remaining light will be excluded. A
point will quickly be reached where adding more curtains has a negligible effect because there is
no light left to stop. This is the case with the absorption of energy as more carbon dioxide is
added to the atmosphere.

4—If greenhouse gases were responsible for increases in global temperature of recent decades,
then atmospheric physics shows that higher levels of CO2 in our atmosphere would show greater
warming than lower levels. This was not found to be true during the 1978 to 1998 period of .3
degrees centigrade warming.

5—A full 900,000 years of ice core temperature records and carbon dioxide content records
show that CO2 increases follow rather than lead increases in Earth temperature, which is logical
because the oceans are the primary source of CO2 and they hold more CO2 when cool than when
warm, so warming causes the oceans to release more CO2.

6—Temperatures have fluctuated over the past 5,000 years, and today Earth’s temperature is
below the average for the past 5,000 years.
