  • That CO2 levels are higher today than they have ever been - FALSE (Figure 10)

Figure 10: This graph shows that CO2 levels have been many magnitudes higher in the past and, that they are at extremely low levels today. In fact, they are some of the lowest levels of CO2 in geologic history. Note that there is no gross correlation between CO2 and temperatures, so heat is a short-term driver. Something else has had a long term effect on the amount of CO2 in the atmosphere. Redrafted from [10,11].
  • That the sea level is rising. TRUE (Figure 11).
  • That the rate of sea level rise is increasing. FALSE. (Figure 11).

Figure 11: Sea level is generally rising as temperature has increased since coming out of the depth of the Little Ice Age about 300 years ago. As temperatures have risen, glaciers are melting. Current variations of sea level are well within natural variability and show no evidence of an accelerating rate, which is required to support the CO2-induced, global warming hypothesis. In fact, the rate may be decelerating. Redrafted from [12].
  • That changes in solar irradiance can be ignored. FALSE (Figure12).

Figure 12: Many astrophysicists believe solar activity is extremely important in affecting temperature. Although correlation does not prove causation, there is a general positive correlation between solar irradiance and temperature. Redrafted from [13,14].
  • That we can ignore the effects of the sun. FALSE (Figure 13).

Figure 13: Solar activity predicts (along with sun spots), that the world will start (plunge) into a very cold period in about 2030 and probably go into a Maunder-type cold spell in 2170 to 2210. These calculations are made with extreme accuracy by atmospheric physicists. Note the extensions below an arbitrary line define each of the major cold periods. Redrafted from [15].
  • That we can ignore sun spots. FALSE. (Figures 14-17).

Figure 14: Recent changes in the sun’s internal conveyor belt suggest possible cooling. Redrafted from [16].

Figure 15: This graph shows maximum and minimum sun spots. These are a natural phenomenon and have approximately 11 year cycles. Redrafted from NASA/ESA Solar and Heliospheric Observatory; Modified from [8].

Figure 16: This graph shows that historically the sun spot numbers increased as the sun came out of the Maunder Minimum (1645 to 1715), a time when the earth was in the throes of the Little Ice Age and there were no sun spots. The correlation between cold intervals and diminished strength of sun spots has held true since the start of keeping records of sun spots. The prediction made in 2006, shown on the dashed line on Figure 16, is correct as shown by the diminished sun spot maximum on (Figure 17). The sun spot cycles are numbered 6-26. Redrafted from [17].

Figure 17: Sunspots are diminishing in intensity as was predicted in 2006. This suggests we are headed toward a cooler climate. Redrafted from [18].
  • That CO2 is a pollutant. FALSE (Figures 18,19).

Figure 18: CO2 is used for growth enhancement in greenhouses. Along with oxygen, CO2 is critical to man’s survival because plants will die without it, and they flourish with it. Redrafted from [19-21].
