Part of the debate – in the House of Lords at 2:42 pm on 28 April 2009.
My Lords, I am reliably informed that any change in the sun's cycle of activity has nothing to do with daylight saving time. My understanding is that the sun's 11-year cycle of activity is currently at a minimum. Although its brightness is lower than during other recent minima, scientists expect its activity to increase again in the coming months. I understand that contrary to what has been reported, the influence of the sun's natural variability on the climate is small compared with the impact of anthropogenic emissions of greenhouse gases.
