Claim: Fossil Fuels Cause Global Warming

Science Matters

Recently I addressed this claim by referring to this chart produced by scientists from AARI.

Figure 5.1. Comparative dynamics of the World Fuel Consumption (WFC) and Global Surface Air Temperature Anomaly (4T), 1861-2000. The thin dashed line represents annual 4T, the bold line—its 13-year smoothing, and the line constructed from rectangles—WF C (in millions of tons of nominal fuel) (Klyashtorin and Lyubushin, 2003).

In their commentary, it is clear why the data does not support claiming fossil fuels cause global warming.  From Frolov et al. 2009:

The WFC curve shows an exponential increase, which doubles approximately every 30 years, increasing 25-fold since the middle of the nineteenth century. The global air temperature anomaly curve shows a positive trend of +0.06°C/10 years (Sonechkin et al., 1997). At the same time, there are cyclic changes with periods of about 60 years. The correlation between these curves changes its…
