The globe has been getting warmer for some time now.
As it happens, the warming roughly parallels a sustained period of growth of industrial activity and fossil fuel consumption.
Some people suspect a cause and effect link between these two concurrent phenomena.
However, the suspicion has not been fully substantiated. Science has yet to
determine without a doubt (and never will) that CO2 emissions from human activity are the primary cause (or even a major cause) of global warming.
