Surface observations indicate that the planet warmed about 0.6 C in the 20th century, 0.8 C since 1850, and about 0.4 C since 1980.

If CO2 is the reason for all this change, what explains the global cooling which occured in the 1930's and 1940's. It is lame to cherry-pick dates to try to portray some rapid warming caused by man. There is a lot more going on that we don't understand. A real scientist would tell you there is no way of knowing what is caused by natural variation and what if any is caused by man. Globull warming is all speculation and fear-mongering to promote world governance and wealth distribution.

Primarily sulfate aerosols. Energy emissions were a lot dirtier in the 1930s and 1940s.

You assert it's "lame", but you don't give a reason why. There's no doubt more remains to be learned and that there are uncertainties. In terms of what a "real scientist" would tell you, I think that they would more accurately say that there are a variety of methods that can be used to estimate natural and anthropogenic contributions to climate change, each with its own inherent uncertainty, and that by examining the results of these various methods, a coherent understanding of these contributions will begin to emerge.
