BBC – Real risk of a Maunder minimum ‘Little Ice Age’

From BBC’s Paul Hudson It’s known by climatologists as the ‘Little Ice Age’, a period in the 1600s when harsh winters across the UK and Europe were often severe. The severe cold went hand in hand with an exceptionally inactive … Continue reading

A link between the solar magnetic field and weather patterns on Earth may explain our lower than normal severe weather in 2013

From the “science is settled” department comes this new paper that points out a correlation between the Interplanetary Magnetic Field (IMF) and polar jet streams, which drive weather events on Earth. This new paper shows that the effects extend even … Continue reading

September doldrums – solar slump continues

While many science related government agencies are shut down (NASA GISS is deemed ‘non-essential’ for example) some remain open due to statements like this: Due to the Federal Government shutdown, NOAA.gov and most associated web sites are unavailable. However, because … Continue reading

Like ‘the pause’ in surface temperatures, ‘the slump’ in solar activity continues

The NOAA Space Weather Prediction Center has updated their monthly graph set and it is becoming even more clear that we are past solar max, and that solar max has been a dud. “The slump” continues not only in sunspot … Continue reading

New paper says ‘No evidence of planetary influence on solar activity’

“Barycentric” influence of the planets on the sun is just statistically insignificant, and a previous paper that claims to find a signal in isotopic records is proven to be nothing more than a statistical artifact. In 2012, Astronomy & Astrophysics … Continue reading
