Solar cycle 24 has seen very low solar activity thus far, likely the lowest in 100 years. The F10.7 flux shows that over the last three and a half years the Sun has gone from solar maximum through a bounded decline to the current stage of the trail to minimum. Solar minimum is likely to be still three years away.

In a joint US-German study, seven scientists recently tried to discredit the sun’s impact on climate. On April 19, 2017, Guoyong Wen and colleagues published a modeling study in the Journal of Space Weather and Space Climate, which suggested a maximum solar-dependent share of 0.1°C on the temperature development over the past 400 years. Here the scientists relied on the old, well-known trick of using the Little Ice Age as the starting.

The sun has looked remarkably blank lately, with few dark cores interrupting the featureless solar disk. This is a sign that Solar Minimum is coming. Indeed, sunspot counts have just reached their lowest level since 2011.

Today marks the 6th day in a row that the sun is blank and the 36th time this year – already more spotless days than all of 2016. In what has turned out to be a historically weak solar cycle (#24), the sun continues to transition away from its solar maximum phase and towards the next solar minimum.

Just in the last few weeks alone, another 20 scientific papers were identified which link solar variations to climate changes, which means 58 papers have already been published in 2017.

The role of solar variability on climate change, despite having a very long scientific tradition, is currently downplayed as a climatic factor within the most popular hypothesis for climate change.
As the root of this neglect lie two fundamental problems. Solar variability is quite small (about 0.1% of total irradiation), and there is no generally accepted mechanism by which the solar variability signal could be amplified by the climate system

For the first time, model calculations show a plausible way that fluctuations in solar activity could have a tangible impact on the climate. Studies funded by the Swiss National Science Foundation expect human-induced global warming to tail off slightly over the next few decades. A weaker sun could reduce temperatures by half a degree.

Third weakest solar cycle since 1755
A recent publication has analyzed the current solar cycle and has found that when sunspot anomalies are compared to the mean for the number of months after cycle start, there have been only two weaker cycles since observations began in 1755. Solar cycle 24 began in 2008 after a historically long and deep solar minimum which puts us more than eight years into the current cycle.

An international team led by researchers at Nagoya University, along with US and Swiss colleagues, has identified a new type of solar event and dated it to the year 5480 BC.
