    “SIM is giving scientists a detailed picture of how the Sun’s ultraviolet emissions vary over its regular 11-year cycle of waxing and waning energy; and it suggests the UV variation is about five times larger than had been inferred from previous observations.

    Meanwhile, scientists including the Met Office team have been publishing papers demonstrating that winter temperatures over Europe and North America do vary with the solar cycle – but without being able to show the mechanism.”
