But there's no other explanation other than man for the temperature change. Nope, none at all.
This is an uninformed statement and not factual. Please cite the study/studies that say this. You can begin by reviewing the ones I've cited already and noting that they do variously discuss sunspot activity and other causes beyond human activity. In fact, the point of several is to determine to what degree human activity plays a part.
Question: are you actually wanting to participate in intellectual and academic discourse on the topic or more interested in tossing out straw man arguments and political soundbites from the undereducated that are somehow threatened by academic inquiry and science?
If your answer is yes, please consider an analysis of the extent to which sunspot activity is a part of recent trend in global temperature increases, taking into account why these trends aren't reflected in past sunspot activity. Then consider ending by taking a moment to comment on the data presented in my last post where you appear to resort to uninformed soundbites that aren't backed by actual science.
Clearly the trend is for warming temperatures which is likely to have detrimental effects on the environment and economy as sea levels rise and agricultural regions experience extended drought. I'm still not sure to what extent human activity plays a part of it, but I still haven't come across data that are suggestive that global warming isn't anthropogenic.
