Sun spotless for 33 days straight – airline travelers getting dosed with up to 70 times more radiation [than at sea level]

Are we in a solar grand minimum? We’ve seen this before, but now predictions are for an extremely weak solar cycle ahead. Today is the summer solstice in the northern hemisphere. The sun has been without a single observable sunspot now for over a month – 33 days according to NOAA and SIDC data. Spaceweather.com…

Study: A Solar Signature in Many Climate Indices

Abstract Jean‐Louis Le MouëlFernand LopesVincent Courtillot We first apply singular spectrum analysis (SSA) to the international sunspot number (ISSN; 1849‐2015) and the count of polar faculae (PF; 1906‐2006). The SSA method finds 22, 11 and 5.5‐year components as the first eigenvectors of these solar activity proxies. We next apply SSA to the ten Madden‐Julian oscillation…

Solar grand minima linked to cooling period in Europe

This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800 years ago during something called the “Homeric minimum”. The paper published in Nature Geoscience suggests that solar grand minima was the trigger for cooling of…

Do Latest Solar Studies Confirm Upcoming Global Cooling?

Guest post by Matti Vooro I fully support the findings of  Jan –Erik Solheim , Kjell Stordahl and Ole Humlum and their very recent paper called The long sunspot cycle 23 predicts a significant temperature decrease in cycle 24  dated February 2012. The abstract reads: Relations between the length of a sunspot cycle and the…

Missing sunspots solved by NASA?

News from NASA that they believe they have solved the mystery of the missing sunspots and why the solar minimum was so prolonged: Researchers Crack the Mystery of the Missing Sunspots March 2, 2011: In 2008-2009, sunspots almost completely disappeared for two years. Solar activity dropped to hundred-year lows; Earth’s upper atmosphere cooled and collapsed;…
