To add my thoughts here.

Yes, I think that the sun's energy is changing in some way. But, not in just the form of heat. It's energy is changing. I don't know how.

This energy change affects some things more than others based on their own internal energy vibrations. Each of us are vibrating at different frequencies and therefore receive this energy from the sun differently. Some feel it as much hotter. Others say it's not hotter at all.

In truth, our whole really is changing all around us based on the changes coming from the sun. BUT, how we receive this change is based on who and what we are inside!

This change is spiritual...
