Is the Sun warmer?

I’ve been talking about the climate for a while now. Back then is was called “the global warming” than “climate change” and now “climate disruption” (only in scientific circles). Why not call it old-fashion “climate is dynamic”?  But then, that wouldn’t sound so politically charged would it ?

I’ve been pondering for a long time, about the sun and how much of the Total Solar Irradiance1 (TSI) is actually transmitted to all planets of our solar system. It the sun itself  is warmer , you can see not just our planet affected ( like the melting of the polar icecaps ) but also Mars, Uranus and Neptune.

Since about 1970s until now, Mars’ ice caps (formed from CO2) are almost completely gone. Mars has an eccentricity of 0.093 and the year around the sun of 1.88 year. It is believed by some that this is due Mars’ naturally waxing and waning ice caps, a phenomena caused by the sublimating and repairing  of the ice caps.2

 

Suppose this is true, let us then take a look at the Neptune.

Neptune has the eccentricity of only 0.0094 and orbital period is 164.8 years. Neptune’s last time solstice was in 1986, while the equinox was in 2007. The first time it was noticed that Neptune’s moon Triton is warmer was in 1998.3 Therefore Neptune itself is also a bit warmer. 

It seems to me that scientists should be more concerned about a warmer sun and whether this is a natural solar cycle ( our sun getting warmer, than cooler) or if our Sun will eventually get warmer and warmer become after half of its life, a red star instead of yellow.4
