Walt.You can see a clear upward trend in temperature even though the solar output actually has had somewhat of a downward trend during the same time. You cant explain this if you ignore the human influence.
I understand that you are in the group of concerned citizen about the human influence as causation for the increase in global temperatures.
if I accept the quote regarding Roy Spencer as being a reliable source of data and information. Then I should also read other quotes and conclusions by this NOAA recognized scientist.
Climate researchers do not know nearly as much about the causes of climate change as they profess. We have a pretty good understanding of how the climate system works on average…but the reasons for small, long-term changes in climate system are still extremely uncertain.
The total amount of CO2 humans have added to the atmosphere in the last 100 years has upset the radiative energy budget of the Earth by only 1%. How the climate system responds to that small “poke” is very uncertain.
I encourage you to read all of his questions and answers to climate - temperature change - and human action as a cause.
