   Scientists used to believe that sunspots were correlated with climate — but then they found there was more funding for disbelieving.

   sigh… Of course that is snark on my part, but how an earth can “scientists” claim that there is no correlation between solar activity and climate? Yes, I know, total solar output stays nearly constant, but the spectrum of solar output changes. “Climate scientists” tell us that solar output spectrum changes do not make a difference, then turn around and say that tiny changes in our atmospheric absorption spectrum drive the planetary climate! Madness!

     Solar Radiation: Sources of Energy for the Earth’s Atmosphere
     (wwwDOT)nasa.gov/mission_pages/sdo/science/Solar%20Irradiance.html

     ***************************
     Solar Radiation – – Energy Flux – Solar Cycle Change – Deposited
     TSI mostly Vis & IR – 1366 W/m2 – 1.2 W/m2 – 0.1% – Surface
     MUV (200-300 nm).- – 15.4 W/m2 – 0.17 W/m2 – 1% – 15-50 km
     FUV (126-200 nm) – – 50 mW/m2 – 15 mW/m2 – 30% – 30-120 km
     EUV (0-125 nm) – – -10 mW/m2 – 10 mW/m2 – 100% – 80-250 km
     ***************************

     Ultraviolet light creates and destroys the ozone layer depending on the wavelength so the changes listed in that chart matter. A shift in the ratio will shift the amount of ozone created vs that destroyed. Ozone production is driven by UV radiation of wavelengths less than 240 nm. Ozone is a highly unstable molecule so when it absorbs low energy UV (240–310 nm) it splits into an ordinary oxygen molecule and a free oxygen atom.

     In the three decades prior to the 2009 solar minimum and the switch to a ‘quiet sun (1979 to 2009) the amount of ultraviolet (UV) radiation reaching Earth’s surface increased markedly. This energy would be absorbed by the oceans at depths up to 100 meters.

     NASA scientists analyzing 30 years of satellite data have found that the amount of ultraviolet (UV) radiation reaching Earth’s surface has increased markedly over the last three decades. Most of the increase has occurred in the mid-and-high latitudes, and there’s been little or no increase in tropical regions.

     …..for example, …at one line of latitude — 32.5 degrees — a line that runs through central Texas in the northern hemisphere and the country of Uruguay in the southern hemisphere, 305 nanometer UV levels have gone up by some 6 percent on average since 1979. [This is addition energy into the oceans at that latitude]

     The primary culprit: decreasing levels of stratospheric ozone….

     The study also shows that increased cloudiness in the southern hemisphere over the 30-year period has impacted UV.

   We were on the right track 50 years ago. Imagine how far we could have come in our understanding of climate if the grantologists had not taken over.

     In more ways than one.

       I think it was Judith Curry who said that we have lost an entire generation of atmospheric scientists to this sad little hoax.

     The graph was supposed to be above, was I missing an “a href…/a”? I used img src(?)

   And now for some breaking news! The sun warms the earth.

   Sunspot count down to 26, and those spots are about to rotate away in a couple days, meaning zero spots soon? http://spaceweather.com/

   Probably not. But possibly.
