#Solar activity is linked NOT to global warming: Sunspot theory of climate change is the result of an ancient error in the data The theory that solar activity is linked to rising global temperatures has been cast into doubt after scientists corrected an ancient error in the calculations.

Until now, the general consensus was that solar activity-in particular sunspots -and temperatures have been trending upwards since the harsh winters of the 17th century when the spots were thought to have been at a low.

But when the error was corrected, the records show there was no such culmination in solar activity in the late 20th century,

suggesting climate change cannot be plotted using this sunspots method. Scroll down for video In fact, solar activity appears to have remained relatively stable

since the 1700s while global temperatures have fluctuated. According to the previous calculations, harsh winters in the 17th and 18th centuries corresponded with low numbers of sunspots,

which suggested a link between climate and solar activity. This period is known as the Maunder Minimum,

and solar activity is said to have peaked in the late 20th century, sometimes called the Modern Grand Maximum, around the time of the Industrial revolution.

known as the Wolf Sunset Number and the Group Sunspot Number, showed different levels of solar activity before 1885,

The Group Sunspot Number had a major error that showed a gradual increase in solar activity for the past 300 years.

we then consider the implications on our knowledge of solar activity over the last 400 years.''

''The newly corrected series clearly indicates a progressive decline of solar activity before the onset of the Maunder Minimum,

solar activity had returned already to levels equivalent to those observed in recent solar cycles in the 20th century.'

#Solar activity impacts polar ozone The increase in greenhouse gases explains to a large extent the rise in the average temperature of Earth.

This climate variability is not a trend like climate change but rather year-to-year fluctuations following solar activity.

but an important one allowing us to better understand the long-term impacts of this type of solar activity
