Weather warning: sun goes THREE WEEKS without sunspots as experts fear the freeze | Science | News


Scientists have been frantically monitoring the sun as a lack of sunspots confirms the worst for our planet.

Experts report that we are now on our twentieth day without a sunspot – the longest time without since 2009.

In 2009, the sun was emerging from the biggest solar minimum for a century.

Experts believe this is evidence we are heading into the solar minimum as a “blank sun” is usually proof that a solar maximum is ending.

The sun follows cycles of roughly 11 years where it reaches a solar maximum and then a solar minimum.

During a solar maximum, the sun gives off more heat and is littered with sunspots. Less heat in a solar minimum is due to a decrease in magnetic waves.

The sun was not expected to head into a solar minimum until around 2020.

According to Space Weather: “The sun is without spots for the 20th straight day. To find an equal stretch of blank suns, you have to go all the way back to September of 2009 when the sun was emerging from the deepest solar minimum in a century.

“The current stretch of spotlessness is a sign that the sun is entering another solar minimum, possibly as deep as the last one.”

The last time there was a prolonged solar minimum, it led to a ‘mini ice-age’, scientifically known as the Maunder minimum – which lasted for 70 years.

The Maunder minimum, which saw seven decades of freezing weather, began in 1645 and lasted through to 1715, and happened when sunspots were exceedingly rare.

During this period, temperatures dropped globally by 1.3 degrees celsius leading to shorter seasons and ultimately food shortages.

Vencore Weather, a meteorological website, said: “Low solar activity is known to have consequences on Earth’s weather and climate and it also is well correlated with an increase in cosmic rays that reach the upper part of the atmosphere.

“The blank sun is a sign that the next solar minimum is approaching and there will be an increasing number of spotless days over the next few years.”
