Despite massive amounts of CO2 emissions over the last 60 years, the long-term trend remains well below a one degree (+0.26°C) increase per century rate.
As the inset chart reveals, the more recent 10-year trend has the representative UK region cooling at an amazing -8.7°C per century rate (a -7.7°C decrease by year 2100).
The following chart is a plot of one-year temperature changes (moving 12-month), with the historical CO2 levels depicted. Clearly, one-year temperature changes are not getting larger, and ever larger, as an "accelerated" warming climate would require.
The red curve is a twenty-year average of the temperature changes, which indicates no long-term influence on CET temperature change by CO2 levels, natural or human.
Conclusion: UK citizens need not worry about "rapid," "accelerating" and "irreversible" warming. There is no credible empirical evidence supporting such CO2-AGW alarmism.
