solar power for CO2 mitigation

Energy from the sun is clean, free and practically limitless. Solar power represents a vast resource which could, in principle, meet the world’s needs for low-carbon power generation many times over. But how much of the world’s electricity might realistically be supplied from the sun? And how far can solar power help us to reduce carbon emissions? read more

is the UK doing enough to protect itself from solar superstorms?

Explosive eruptions of energy from the Sun that cause minor solar storms on Earth are relatively common events. Superstorms, by contrast, occur very occasionally – perhaps once every century or two. A new report by the Royal Academy of Engineering brings together engineering and scientific experts from across many disciplines to identify and analyse the impact of solar superstorms on the UK’s engineering infrastructure. read more

solar activity and climate

The lead authors of a paper in Nature describing unexpected changes in the sun’s spectrum came into the SMC to discuss their findings and the implications for the effects of solar variability on climate. read more

experts comment on research into a possible link between skin cancer and moisturisers, as published in the Journal of Investigative Dermatology

Researchers in the US found that the application of moisturiser to mice following sun exposure led to a higher incidence of skin cancer tumour formation. A number of ingredients in the moisturisers were identified as possible causes of the higher rate of tumour formation, but the authors indicated that similar findings have not been established in humans. read more

the importance of vitamin D for human health

There is unequivocal evidence of serious, adverse effects from over exposure to sunlight in terms of skin cancers and cataracts, but there is also accumulating evidence that sunlight exposure, acting via its role in vitamin D synthesis, can protect against certain diseases. Experts discuss whether this raises a dilemma between the risks of sunlight exposure against its benefits or whether we can safely obtain all the Vitamin D we need. read more
