New study confirms ‘solar activity has a direct impact on Earth’s cloud cover’ important to climate change

A new study confirms “solar variations affect the abundance of clouds in our atmosphere,” a solar amplification mechanism which is the basis of Svensmark’s theory of cosmo-climatology.

The solar eruptions are known to shield Earth’s atmosphere from cosmic rays. However, the new study, published in Journal of Geophysical Research: Space Physics, shows that the global cloud cover is simultaneously reduced, supporting the idea that cosmic rays are important for cloud formation. The eruptions cause a reduction in cloud fraction of about 2 percent corresponding to roughly a billion tonnes of liquid water disappearing from the atmosphere.

As Dr. Roy Spencer notes,
“The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.”

The IPCC models fail to consider multiple solar amplification mechanisms, including cosmic rays and numerous other amplification mechanisms, thereby ignoring that solar activity can explain the 0.7C global warming since the end of the Little Ice Age in 1850. Solar activity reached a grand maximum in the latter half of the 20th century, and accumulated solar energy (the ‘sunspot integral’) explains global temperature change since 1900 with greater than 97% statistical significance. This new paper confirms that solar activity variation can account for a 2% variation in global cloud cover, sufficient to explain the warming of the 20th century and without any consideration of CO2 “radiative forcing.”

With a quiet sun on the horizon, we can expect more clouds and more cooling. Some scientists are predicting Solar Cycle-25 will be less active than the current Solar Cycle-24. Other scientists are not so sure, predicting that SC-25 will be similar to SC-25. This study provides a mechanism for the Maunder Minimum to cool the planet, creating brutal winters and cool summers, shortening the growing season with late spring frost and early fall storms. We could be on the cusp of the next grand minimum; only time will validate this assumption.

    There is an interesting cross reference between the ‘Global Temperature Anomaly Graph’ and certain UK Church records – one of the principle sources of direct observation of information and ‘real world’ happenings. Referred to as the ‘Demographic Crises 1739-1744’ it shows a doubling of recorded burials (deaths) and a halving of baptisms (births) during that period.
    An extract from church records reads …
    ”The summer of 1739 was a very dry one, Bishop Wilson describing it as the ” severest drought ” that he ever remembered – this led to a very poor harvest and a much reduced hay crop needed to feed animals during the winter, the winter of 1739-40 was very cold, and the harvest in 1740 was again a poor one”
    This provides us with a very human interpretation of what is otherwise just harsh scientific data.

      I am currently reading A Cultural History of Climate by Wolfgang Behringer which is about the human impact that climate change has large populations, more deaths and fewer births.

      Thanks for the heads up to these excellent arguments for sun and cloud driven climate change. I hope all readers will take the time to read the No Tricks Zone post at the link you posted. Great comment, thanks!!
