No, that's certainly not all. The warming trend that climate scientists are most concerned about, the one that is seen as the salient indicator of human effects on climate, is the one that started in the mid-1980s. Because of a slight cooling mid-century, the full global warming increase in the 20th century was 0.6 C. Since the mid-1980s, the global temperature has increased about 0.4 C. I believe that six of the 10 warmest years in the 20th century were in the 1990s. All of this (and more) is seen as the human effect "signal" emerging from the climate variability "noise".

It could just as well be that obscurants from burning rain forests, (and cities in WW-II) as well as general "soot", put a blip in what would otherwise be a general warming trend, as shown in the historical record that you posted above.

SO2 from rapid re-industrialization is also blamed.

The blip extends from roughly 1945 to 1986 and coincides, roughly, with the duration of atmospheric nuclear testing.
