Svensmark, a senior researcher in the Astrophysics and Atmospheric Physics Division of the National Space Institute (DTU Space) in Lyngby, Denmark, says that solar activity “has had a significant impact on climate during the Holocene period.”
Numerous studies have shown that throughout the Holocene period (approximately the last 10,000 years) there has been a strong correlation between solar activity and global warming and cooling.
A well-known example is the existence of high solar activity during the Medieval Warm Period, around the year 1000 AD, and the subsequent low levels of solar activity during the cold period, now called The Little Ice Age (1300–1850 AD).
Yet astonishingly the official consensus continues to play down this connection by insisting that the influence of solar activity on climate change is negligible. The reason for this, Svensmark suggests, is that if the sun’s effect on climate change were properly acknowledged then it would involve downgrading the influence of CO2.
“…The official consensus from the Intergovernmental Panel on Climate Change.. [estimates] that the change in solar radiative forcing between 1750 and 2011 was around 0.05 W/m2, a value which is entirely negligible relative to the effect of greenhouse gases, estimated at around 2.3 W/m2. However, the existence of an atmospheric solar-amplification mechanism would have implications for the estimated climate sensitivity to carbon dioxide, suggesting that it is much lower than currently thought.”
In other words, nobody in the climate alarmist establishment wants to admit the importance of the Sun because if they did, bang would go their theory – and attendant funding gravy train – that man-made CO2 is a significant and potentially dangerous driver of climate change.
