So.....it's not the Sun's fault ......it's the Earth's fault.......or the Solar system........or the galaxy
You mean "scientists" have only now figured out what makes "winter" in northern climates? In fact isn't today the earths max. tilt away from the sun at the north pole? (the shortest day of the year)
(I really don't buy this "shift" in the earths orbit around the sun changing from circular to elliptical and back again either. Maybe it's just the earths wobble stabliizing slowly, makes more sense.)
