Here are recent statements by vocal media impressarios and think tanks who spend their time, not in a laboratory, but in the popular media trying to convince the public that global warming is either not happening, or is not caused by our continued consumption of fossil fuels (oil, coal, gas etc). Below each one, I have also provided an historical quote on what they had to say about the effects of CFC's on the hole in the o-zone layer. Notice any similarities?

Tim Ball
Tim Ball on CFCs' [7] and ozone: "CFC's were never a problem… it's only because the sun in changing." And, "fluctuation of ozone in the stratosphere is likely a natural phenomenon because solar radiation is a fluctuating event." (Western Standard, June, 1993)

Tim Ball on global warming: "The climate is changing all the time, and what's going on right now is well within natural variability."(Saskatchewan Leader Post, July, 2006)

Fred Singer
Singer on CFC's and ozone [8] : "The hypothesis that CFCs deplete ozone is still just that: a hypothesis. The theory did not predict the Antarctic ozone hole and cannot predict what will happen globally. There is no firm evidence as yet for a long-term depletion of global ozone. Much of data is contaminated; the ozone record is dominated by large, natural fluctuations on many time scales…"

Singer on global warming [9] : "Greenhouse warming will be barely detectable and within the "noise" of natural, year-to-year temperature changes." And [10], "there has been no warming observed as yet as a result of the ongoing human-caused CO2 increase."

Hugh Ellsaesser
Ellsaesser on CFC's and ozone [11] : "The public has been misled to an even great in that the possible beneficial consequences of increased UV have been consistently ignored." (sic.) And, "There has indeed been a slight decline in global ozone levels, probably due to sunspot activity and natural dynamics in the atmosphere."

Ellsaesser on global warming [12] : "Natural variability in the Earth's climate easily exceeds recent global temperature trends."

National Centre for Public Policy Research
On CFC's and ozone [13]: "The impact of CFCs on the ozone layer is not fully known. Changes in weather patterns, the eruption of volcanos, changes in ultraviolet output of the sun linked to the 10-11 year solar cycle and other natural phenomena can, like CFCs, inhibit the production of ozone."

On global warming [14]: "A careful examination of the Earth's climate history, however, shows that this warming is the result of a natural fluctuation in temperature and poses no threat to humanity."
