Canadian Temperature Records Show No Response to CO₂

Temperature trends well established prior to 1970 continue to the present day

It is clear that CO₂ levels have NO EFFECT on Temperature....

Historical Temperatures for Churchill, Manitoba show a slow but steady temperature increase beginning before CO₂ increased and continuing at the same rate up to the present day

What Canadians Have Been Told About Anthropologic Global Warming is a Lie!

Although Temperature appears to correlate with CO₂, it does not

• In Period #1, temperature increases at the same rate when CO₂ is ~300 - 310 ppm as it does with much higher CO₂ in Period #3
• In Period #2, temperature actually decreases while CO₂ increases

There is No Statistically Significant Correlation Between CO₂ and Temperature

Standard statistical methods clearly demonstrate there is no correlation and therefore no causation.

• To prove causation, there must be a Proportional Change in Temperature for every Change in CO₂. This relationship must be consistent across the Full Range of ALL Data Points.
• The Rate of Change (RoC) in Period #1 is almost identical to that in Period #3 even though CO₂ is at significantly different levels. This clearly shows that CO₂ does not drive Temperature.
• The RoC in Period #2 further demonstrates that there is no Link. Temperature is independent of CO₂.
• Therefore, CO₂ is NOT the Control Knob for Temperature.

Correlation does not prove causation

• The story is told in the "Residuals"
• When "Residuals" are not equally distributed, it proves there is no correlation

Here is a what a Temperature Profile Would Look Like if CO₂ did in Fact Drive Temperature

• The first graph (1 of 2) shows a simulation of actual temperature data from a Canadian Location that has had a Theoretical CO₂ effect applied
• Temperature Data prior to 1974 is real data without a CO₂ affect applied. Note that it shows a steady decline in temperature
• Data from 1974 onward is the actual temperature to which a simulated CO₂ has been added
• Post 1974, a very clear and well defined upward trend can be observed.

But clearly, there is no correlation between increasing CO₂ and unmodified measurement data

• In the second graph (2 of 2) the downward trend from 1935 to 1974 continues to the present day
• Note the relatively cooler period that begins in 1980 and continues to 1998. This is why AGW proponents frequently use 1980 as a starting point when they display temperature data. Without seeing earlier data, it falsely suggests that temperatures are increasing

This is a simulation only and does not reflect actual temperature measurements

This is real measurement data showing no correlation with CO₂

Climate Alarmists Constantly Modify Temperature Measurements to Hide the Inconvenient Truth

• Early Temperatures are adjusted downward to show cooler periods pre-1980
• High temperatures in the 1920s and 1930s contradict the AGW propaganda that we are now seeing unprecedented high temperatures
• Later Temperatures are adjusted upward to suggest there is more warming than there actually is
• To understand the reasoning behind this charade, just FOLLOW THE MONEY!

Don't be fooled by a chart where the temperature scale is set to show only a few degrees

In Canada, normal temperatures range up to 70 C and a variation of a few degrees is meaningless

Even several degrees of warming will not have a noticeable effect on Canadians

• This example assumes 3 degrees of warming. This is the "existential" threat we have been warned about
• Higher temperatures will only be felt on a few days each year
• Except for a few days at the height of summer, temperatures will not be outside of the normal range
• There would be several positive effects including a slightly longer growing season and possibly reduced heating costs
