Models have long suggested that Earth’s orbit shifts from circular to elliptical and back again over hundreds of thousands of years, which plays a part in natural climate swings. Now, scientists have found the first physical evidence for the cycle, and traced it back to before the dinosaurs.

Open minds needed for this

Right now! perihelion to aphelion affect a fluctuation in solar radiation of 92 W/m^2 EVERY year. Makes mankind’s 263 year’s worth of 2 W/m^2 and IPCC’s worst^4 case 8.5 W/m^2 scenario look like rounding errors.
For the up/down/”back” radiation of greenhouse theory’s GHG energy loop to function as advertised earth’s “surface” must radiate as an ideal black body, i.e. 16 C/289 K, 1.0 emissivity = 396 W/m^2.
As demonstrated by my modest experiment (1 & 2) the presence of the atmospheric molecules participating in the conductive, convective and latent heat movement processes renders this ideal black body radiation impossible. Radiation’s actual share and effective emissivity is 0.16, 63/396.
Without the GHG energy loop, radiative greenhouse theory collapses.
Without RGHE theory, man-caused climate change does not exist.
Of course, that doesn’t stop hosts of “experts” ‘splaining the mechanism of this non-existence with quantum electro-dynamics, molecular level physics, photo-electrics which all ends up pretentious, handwavium, nonsense.
