As a result of toxic CO2, the Earth is orbiting the Sun at its slowest speed in a year. Wait, actually it's the aphelion, which happens this time of year. At 2:41 p.m. Central today, we'll be the farthest we get from the Sun in our elliptical orbit. We don't notice the resulting decrease in insolation here in the Northern Hemisphere, because the effect of being tilted toward the Sun in summer overwhelms the effect of being 3 million miles farther from the Sun than we were in January.
The slow-down, a natural aspect of orbital mechanics rather than a plot between The Heartland Institute and Big Fossil Fuel, means that summer lasts 5-1/2 days longer in the Northern Hemisphere than in the Southern.
