Data were not corrected for sunlight effects.
Sunlight effects can be analyzed by comparing the Northern and Southern hemispheres in both figures separately and by comparing the same hemispheres in the two figures.
To control for heat versus sunlight effects, some of these plaques were wrapped in thick aluminum foil.
The robustness of our seasonality effects, combined with the transient nature of our sunlight effects, led us to conclude that, when using monthly data, the association between sunlight exposure and suicide appeared to be a proxy for seasonality and suicide.
To control for heat versus sunlight effects, Tritan™ plaques were fully wrapped in aluminum foil to avoid exposure to sunlight and were kept on the roof for up to 14 days (negative controls).
Using monthly data, the robustness of our month of year effects, combined with the transient and modest nature of our sunlight effects, suggested that the association between sunlight exposure and suicide was a proxy for the association between seasonality and suicide.
Going to call it, "Wheatstack in the Sunlight, Morning Effect".
An exciting project, launched as the Global Apollo programme in 2015 and taken up, thanks to Bill Gates' ministrations, by 20 major governments at the Paris climate conference in December 2015, is to produce liquid fuels and methane directly from carbon dioxide using sunlight – in effect, mimicking the photosynthesis that every plant accomplishes so easily.
Under natural conditions, i.e., outdoors in sunlight, the effect of a blue light-filter on glare disability could be even more substantial, since the natural background could contain even more short-wave energy.
That would convert the Arctic Ocean from a brilliantly white reflector sending 80% of solar energy back into space into a heat collector absorbing 80% of incident sunlight, with effects on ocean and atmospheric circulation extending into mid-latitudes.
It turned out that reducing sunlight offset the effect of CO2 both regionally and seasonally.
