OOPS That Human Caused Global Warming Thingy is all WRONG

Climate alarmism is based in substantial part on the assumption that other causes of global warming can be accounted for, and whatever is left over must be due to human-emitted CO2. This sort of reasoning is rarely valid, but it is particularly inappropriate in a field as little understood as climate. One obvious reason why the Earth has gotten warmer and colder over the millenia is that the amount of energy put out by the Sun varies. Moreover, over the last few centuries, sunspots–considered to be a good proxy for solar activity–have correlated very closely with Earth temperatures. More sunspots equal higher temperatures.
It shouldn’t be a surprise that variations in the Sun’s output are responsible, at least in part, for variations in Earth’s temperatures. The problem is that if you simply do the math on radiant heat, the known increase in solar activity during the second half of the 20th century accounts for only a small portion of the assumed increase in temperature over that period. So the alarmists have denied that the Sun plays a significant role. More recent work has strongly suggested that solar radiation plays a role above and beyond radiant heat, by influencing cloud cover, which is a key factor in temperature. Given the strong correlation between solar activity and temperature, this work has been persuasive.
