Daylight robbery

Geoengineering experiments, Solar radiation management (SRM)

It’s called daylight robbery

Experiments to dim the Sun will be approved within weeks

Experiments to 'dim the Sun' to be given green light by UK government

I do not consent

I am worried about national and global food supply

If food supply is controlled then we are controlled

All food chains start with photosynthesis

Photosynthesis depends on sunlight (or artificial light)

Photosynthesis takes CO2 out of the atmosphere

Photosynthesis puts O2 into the atmosphere

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.

All life on Earth depends on photosynthesis (except deep ocean hot vents)

Ecosystems require an energy input, complex interacting webs, plants, animals, insects, bacteria, fungi, viruses

I would prefer ‘scientists’ not to mess about with my food and oxygen supply

I am concerned about unexpected effects, butterfly effects, chaos effects, runaway effects.

Biodiversity

Accountability?

Let’s plant trees, promote plant / animal ecology, farm seaweed and marine phytoplankton.

Other risks

Unforeseen chaotic effects

Disruption of weather patterns, rainfall, monsoons, hurricanes, all leading to potential food shortage

Uneven effects leading to regional drought and famine, geopolitical tensions

Dose not address root problems, it’s a single feature intervention

Starting and stopping effects

Water cycle effects

Unknown longer term effects, ozone layer, air quality, ecosystems

Who decides

UVB

Disinfectant

Vitamin D

Red light, benefits

Red light penetrates to the mitochondria

SAD

Worse in winter

Dementia

Better memories, slept better, angry less often

Pain

May be useful for relieving some pains, particularly pain due to inflammation

Rheumatoid arthritis

Treatment for pain and morning stiffness for patients with rheumatoid arthritis

Tendinopathy

May help relieve pain or improve function

Androgenic alopecia

Outdoor field trials could include

Sunlight reflection methods
