You are given facts, and because you classify those who provide them as "climate-skeptics", you claim that they should no longer be taken into account.
If I adopt
irrational position, I would be saying that there is no warming since it is the climate-activists of the IPCC who affirm it!
The thermal energy of the earth comes mainly from the sun, and the sun has a cycle of 11 years alternating a period of very high activity (visible by the multitude and extent of sunspots) and a period of low activity (more no sunspot).
This difference is not trivial and can be easily seen. All radio amateurs know that the highs of the activity allow them contacts on higher and higher frequencies, even allowing to receive in North America the TV signals of North America above 50 MHz, while in low activity, even 13 MHz frequencies can not always be used. This is the direct result of the solar activity on the ionization of the upper atmosphere layers, which varies enormously according to the amount of energy received.
These cycles are not constant, the maximum height of the activity depends on the cycles. After the big peaks of the 80 years, NASA's predictions of solar activity show a decline, and contrary to IPCC forecasts, NASA's forecasts are correct, for example the last max of the
the 24 cycle has been well predicted.
NASA says it affects the climate:
"the solar-plus-ozone change leads to increased tropical stratospheric warming in the mid-to-upper stratosphere during solar maximum conditions."
"Total solar irradiance changes, though of small magnitude, do appear to affect sea surface temperatures (SSTs)"
https://www.giss.nasa.gov/research/briefs/rind_03/It does not seem to me that NASA is a misinformation organization.
To claim that the decline in solar activity, and thus the amount of energy received by the earth, would have no impact on the climate, is a wish.
