Recent Climate Change
I have written in the past about intriguing, very strong correlations between measures of solar activity and the global temperature. A new Danish experiment now adds a causal connection.
Solar activity modulates the magnetic field in space, which strongly affects how much cosmic ray flux reaches the Earth. The new experiment shows that flux strongly affects cloud cover on Earth. See this link ->

More cosmic rays means more clouds; clouds are 10x more efficacious in cooling than CO2 is for warming. More solar activity means LESS clouds, as the magnetic fields in space shield the Earth. Guess what? Solar activity was strong for recent decades, while the global warming knaves were pontificating about their computer models (which ignore solar affects).
During known cool periods on Earth, such as the 17th century, solar activity is know to have been very weak or nil.
The computer models costing untold billions are all wrong. All the blather about humans causing global climate change (warming) are wrong. The Sun is doing it, and has done it for thousands of years.
QED.
Remark on Last Week's Problems
On Friday the blog sponsor (Google) had serious problems and lost a few posts; posting was not possible Friday. I believe the lost posts of late last week are restored.

How do they measure solar activity in the 17th century??
Easy, They counted sunspots. In the 17th century there were very few or no sunspots for decades.
Solar activity occurs in regions around sunspots, called "active regions" ;)
they can track solar activity for a few thousand years from carbon-14.
Also, those periods of much solar activity track to periods known as being warmer from historical sources, such as the Medieval Climatic Optimum circa 1100AD.
The period of the solar cycle is the key measure of how intense the cycle is.
