Default Sunspots at 1000-year high: BBC News

LOL!

Great writing:

"They say that over the last century the number of sunspots rose at the same
time that the Earth's climate became steadily warmer.

This trend is being amplified by gases from fossil fuel burning, they
argue."

Read one way, fossil fuel burning 93,000,000 miles away caused an increase
in the number of sunspots.

Even read the other way, the author is making up his own "facts."

Sunspots reaching 1,000-year high

By Dr David Whitehouse
BBC News Online science editor

A new analysis shows that the Sun is more active now than it has been at

anytime
in the previous 1,000 years.

Scientists based at the Institute for Astronomy in Zurich used ice cores

from
Greenland to construct a picture of our star's activity in the past.

They say that over the last century the number of sunspots rose at the

same
time that the Earth's climate became steadily warmer.

This trend is being amplified by gases from fossil fuel burning, they

argue.

Sunspots have been monitored on the Sun since 1610, shortly after the

invention
of the telescope. They provide the longest-running direct measurement of

our
star's activity.

The variation in sunspot numbers has revealed the Sun's 11-year cycle of
activity as well as other, longer-term changes.

In particular, it has been noted that between about 1645 and 1715, few

sunspots
were seen on the Sun's surface.

This period is called the Maunder Minimum after the English astronomer

who
studied it.

Ice cores record climate trends back beyond human measurements
It coincided with a spell of prolonged cold weather often referred to as

the
"Little Ice Age". Solar scientists strongly suspect there is a link

between the
two events - but the exact mechanism remains elusive.

Over the past few thousand years there is evidence of earlier

Maunder-like
coolings in the Earth's climate - indicated by tree-ring measurements that

show
slow growth due to prolonged cold.

In an attempt to determine what happened to sunspots during these other

cold
periods, Dr Sami Solanki and colleagues have looked at concentrations of a

form,
or isotope, of beryllium in ice cores from Greenland.

The isotope is created by cosmic rays - high-energy particles from the

depths
of the galaxy.

The flux of cosmic rays reaching the Earth's surface is modulated by the
strength of the solar wind, the charged particles that stream away from

the
Sun's surface.

And since the strength of the solar wind varies over the sunspot cycle,

the
amount of beryllium in the ice at a time in the past can therefore be used

to
infer the state of the Sun and, roughly, the number of sunspots.

Dr Solanki is presenting a paper on the reconstruction of past solar

activity -
entitled Cool Stars, Stellar Systems And The Sun - at a conference in

Hamburg,
Germany.

He says that the reconstruction shows the Maunder Minimum and the other

minima
that are known in the past thousand years.

But the most striking feature, he says, is that looking at the past 1,150

years
the Sun has never been as active as it has been during the past 60 years.

Over the past few hundred years, there has been a steady increase in the
numbers of sunspots, a trend that has accelerated in the past century,

just at
the time when the Earth has been getting warmer.

The data suggests that changing solar activity is influencing in some way

the
global climate causing the world to get warmer.

Over the past 20 years, however, the number of sunspots has remained

roughly
constant, yet the average temperature of the Earth has continued to

increase.

This is put down to a human-produced greenhouse effect caused by the

combustion
of fossil fuels.

This latest analysis shows that the Sun has had a considerable influence

on the
global climate in the past, causing the Earth to warm or chill, and that

mankind
is amplifying the Sun's latest attempt to warm the Earth.

There's a third, proper way to read it. Two events, unassociated with
each other, are causing a cumulative warming trend on the earth. Grazing
cow farts also add to the green house gases and again, have no direct
relationship with sunspots or fossil fuel burning.

And the growing global population -- all exhaling CO2.

True. Add forest fires also. A disturbing fact is that as the oceans
warm up, they can hold less co2 in suspension. The oceans absorb the
vast majority of the stuff.

This thing with co2 may be just a cover. It's easy to forget that
wherever co2 is produced there well may well be toxic carcinogens being
dumped at the same time. Someone is putting the greenhouse agenda in the
public eye to get the attention off the manufactured toxins accompanying
the non poisonous co2

Communist China has really lax pollution laws. That explains why it's
attracting the Capitalists so quickly. That and the stable slave labour
force..and the low taxes...

Ohm: Someone is putting the greenhouse agenda in the public eye to get the

You have a good point. CO2 is natural as is water vapor, which has the same
effect upon the warming situation. To lump CO2 with all the toxic and even
synthetic stuff is something I disagree with.

You might check out my severe hurricane treatise, which covers ocean warming,
etc.
