The sun hasn’t decided what it wants to do yet.

Another new solar sunspot record peak of 73.2 was set for Cycle 24 last month. It smashed the old 68.9 record peak set the previous month. In a big surprise, it’s over six spots higher than the first sunspot peak … Continue reading

Real risk of a Maunder minimum ‘Little Ice Age’ says leading scientist

The BBC has the story: 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 … Continue reading

Since Dalton-Minimum 190 years ago, never has the sun been so inactive.

Currently solar activity is especially low. Solar sunspot number (SSN) in September was at 36.9, and thus was just 36% of the usual mean value 58 months into the cycle. The sun continues to remain in an unusually weak cycle 24, … Continue reading

New paper finds another amplification mechanism by which the Sun controls climate

A paper published today in Quaternary Science Reviews reconstructs climate of the central Alps over the past 10,000 years and finds precipitation and floods were driven by changes in solar activity. The authors propose variations in solar activity and insolation … Continue reading

Swiss scientists now say that the Little Ice Age most certainly could have been triggered by variations in solar activity.

There’s been criticism for the Intergovernmental Panel on Climate Change (IPCC) over its latest AR5 report from many quarters for many reasons. But today there’s new research focusing on one particular aspect of that criticism. The particular part of the … Continue reading

Svensmark’s cosmic ray theory of clouds and global warming looks to be confirmed

Originally posted on Watts Up With That?:
Note: Between flaccid climate sensitivity, ENSO driving “the pause”, and now this, it looks like the upcoming IPCC AR5 report will be obsolete the day it is released. From a Technical University of…
