The mercury could plummet in the thermosphere - a layer of gases
around 60 to 180 miles (100 to 300km) above the planet's surface -
as a result of the sun's inactivity.
Sunspots are not fully understood but they occur over regions of
intense magnetic activity as part of the 11 year solar cycle.
Ultra-violet radiation sent out across the cosmos from these
sunspots agitates particles in the Earth's atmosphere, causing them
to heat up.
Sunspots have been absent from the surface of the sun for most of
this year, causing the Earth's upper atmosphere to lose heat energy
as a result of the lack of agitation.
However, research has shown these changes high above Earth are
unlikely to have much of an impact on weather at the planet's
surface - including climate change.
A lack of sunspots
could herald in a 'Space Age record'
for cold temperatures in the thermosphere,
a scientist has warned.
Researchers worked this out
using NASA's TIMED satellite (pictured)
which measures changes
the Earth's atmosphere.
'High above Earth's
surface, near the edge of space, our atmosphere is losing heat
energy', Dr Mlynczak told Dr Tony Phillips as part of an
in-depth feature in Space Weather.
'If current trends continue, it could soon set a Space Age
record for cold', he added.

found this out by using the SABER instrument on the TIMED satellite,
which monitors infrared emissions from carbon dioxide and nitric

Mlynczav created the 'Thermosphere Climate Index' (TCI).
This number - which is expressed in Watts - shows how many heat
trapping molecules like carbon dioxide and nitric oxide are released

33 billion Watts of infrared power from NO [nitric oxide]', Dr
'That's 10 times smaller than we see during more active phases
of the solar cycle.'
It could set a record in
a 'matter of months' Dr Mlynczak said.

the result of a lack of sunspot activity in the star's magnetic

WHY DO FEWER
SUNSPOTS CAUSE MORE PROBLEMS ON EARTH?
Lack of sunspot activity in the sun is due to a continuing period of
inactivity in the star's magnetic field.
As the sun moves through its 11-year cycle, it experiences active
and quiet periods known as the solar maximum and solar minimum.
As solar minimum approaches, certain types of activity - such as
sunspots and solar flares - will drop, but it's also expected to
increase long-lived phenomena.
This includes coronal holes, where fast moving solar winds are
created when the star's magnetic field opens up into space. This
happens more regularly as the sun's magnetic field becomes less

Charged particles make their way out into the solar system through
these gaps and hit the atmosphere of our planet.

An increase in solar
winds can also alter the chemistry of Earth's upper atmosphere,
which may trigger more lightning and aid in cloud formation.
