The effects of UV radiation on photosynthesis …
The reason that UV-B and all other aspects of the spectrum impact us all more is because of the technology of wireless including transients radiating for wiring (dirty electricity). Like nuclear radiation turned down to a lower level and thus causing a slower demise, wireless signals travel far (how else do people get messages?) and exist in the air, interacting with the sunlight. The same is true for radio signals. Electrical wiring also runs not only 60 hertz electricity, but often the hertz of computer and other electrical gear, at the kilo, mega or gigahertz levels–as these run down the wires designed to contain 60 hertz, the wiring is not designed for this and thus invisible transients come off the wiring–like an electrical field at a different hertz. All of these invisible wireless frequencies have been shown to amp up cancer and, like nuclear, can increase burning. There is on the internet somewhere a study showing AM towers and wireless causing increased cancers with geographic location near towers. Very well done visual study, perhaps by Halberg (sp?) or Johannesson (sp?) from the Karolinski Institute? from Sweden or Finland? I can’t recall. But these wireless signals from all sources are causing increased damage.
INFLUENCE OF UV-B RADIATION ON PHOTOSYNTHESIS …
To help indicate how colors will appear under different light sources, a system was devised some years ago that mathematically compares how a light source shifts the location of eight specified pastel colors on a version of the C.I.E. color space as compared to the same colors lighted by a reference source of the same Color Temperature. If there is no change in appearance, the source in question is given a CRI of 100 by definition. From 2000K to 5000K, the reference source is the Black Body Radiator and above 5000K, it is an agreed upon form of daylight.
A CRI of 100 has a heavy red spectrum. The color temperature is 2700 K for incandescent light and 3000 K for halogen light. An incandescent lamp, virtually by definition, has a Color Rendering Index (CRI) close to 100.
This does not mean that an incandescent lamp is a perfect color rendering light source. It is not. It is very weak in blue, as anyone who has tried to sort out navy blues, royal blues, & black under low levels of incandescent lighting.
Interestingly (& sadly), many lower end aquarium LED lights are matching their lights to CRI ratings. The results is a brighter light that looks good to us, often brings out colors to our human eyes, but are actually much less efficient for plant & especially coral growth. Two popular offenders are the Finnex & Fluval.
Common sense should tell one that the tropical noon time sun is 6500 kelvin and this it the optimum light for plant growth, not what looks best and brightest to us!!!
In Jalisco you were probably getting uvA=aging(longer cooler waves; a chronic long term wave for skin cancer to develop) while in San Pedro you were receiving uvB=burning(shorter harsher waves – less chance for skin cancer bc you will not stay in the burning sunlight for very long)
Photosynthesis Science Fair Projects and Experiments
We have known for some time that the UV levels were getting rapidly worse due to the ongoing atmospheric spraying. Anyone that is even slightly awake and aware has noticed that the sun feels incredibly intense on the skin. Most varieties of plant life are showing at least some signs of stress in most areas. In many regions, whole forests are in steep decline. And its getting worse by the day.
Geoengineering Is Destroying The Ozone Layer - …
Morphological characteristics of Arthrospira or Spirulina species are often related to product quality. In addition, the length of the spiral filament is very important for harvesting efficiency. Thus, breakage of filaments by solar UVR in outdoor cultures negatively influences the quality and yield of the harvested biomass. On the other hand, an increase in UV-B radiation due to ozone depletion, as forecast for the early 21st century, might alter the morphological development of cyanobacteria. Consequently, this effect on the shapes and sizes could ultimately affect higher trophic levels, as both metabolic rates () and grazing behavior in aquatic ecosystems highly depend on these parameters.

Morphological changes in A. platensis, such as helix pitch, spiral width, or orientation, have been reported under laboratory conditions (, , , , ). It seems that laboratory conditions, without any impact of UVR, favor the development of straight forms (, , ). In addition, it was found that A. platensis strains with a tight helical structure could tolerate higher light intensity than strains with loose spirals () and that loose straight filaments could be transformed to tight coiled shapes when the cells were shifted to high-light conditions (). Our study further demonstrates that A. platensis responds to solar UVR by changing its spiral structure. It appeared that such morphological changes from a loose helix to a tight helix, induced by UVR (as seen in our work) or by high levels of visible light (as determined by another researcher ), are associated with the protective strategy of this cyanobacterium to counteract solar UVR or high PAR levels by increasing self-shading.
This tutorial introduces electromagnetic radiation in physics
Although extreme drought and toxic rains (due in large part to the heavy metal fallout from geoengineering) are taking their toll, recent metering of UV levels in Northern California indicate that there is an element in this die off that is far worse than we had realized, an incomprehensibly high level of UV radiation.
