Earth Orbit's Wobble Key to West Antarctic Warming in Last Ice Age
Earth's orbit can drastically affect our planet's climate. In fact, the wobbly nature of its path can cause our planet's ice ages. Now, though, scientists are uncovering a little bit more about the Northern Hemisphere's last ice age. It turns out that Antarctic warming began at least two, and perhaps four, millennia earlier than we previously thought.
...
The scientists analyzed this core by running two electrodes along the ice to measure high electrical conductivity associated with each summer season. This allowed the researchers to identify the annual layers in the core. Evidence of greater warming turned up in layers associated with 18,000 to 22,000 years ago, the beginning of the last deglaciation.
...
It's likely that the warming in West Antarctica 20,000 years ago was due to how the sun's energy was distributed over the region. It not only warmed the ice sheet, but also warmed the Southern Ocean that surrounds Antarctica, particularly during summer months when more sea ice melting could take place.

The findings reveal a little bit more about the Earth's climate history and also might show a little bit more about future climate changes. That said, it's unlikely that changes in Earth's orbit today are an important factor in the current rapid warming.

http://www.britannica.com/EBchecked/topic/190813/precession-of-the-equinoxes

Precession of the equinoxes, motion of the equinoxes along the ecliptic (the plane of Earth’s orbit) caused by the cyclic precession of Earth’s axis of rotation.

In compiling his famous star catalog (completed in 129 bce), the Greek astronomer Hipparchus noticed that the positions of the stars were shifted in a systematic way from earlier Babylonian (Chaldean) measures. This indicated that it was not the stars that were moving but rather the observing platform—Earth. Such a motion is called precession and consists of a cyclic wobbling in the orientation of Earth’s axis of rotation with a period of 25,772 years. Precession was the third-discovered motion of Earth, after the far more obvious daily rotation and annual revolution. Precession is caused by the gravitational influence of the Sun and the Moon acting on Earth’s equatorial bulge. To a much lesser extent, the planets exert influence as well.

22000 years and 25772 years. There can't be a correlation, it has to be CO2! I've spent my entire career saying it is CO2! It will be CO2! Never mind that I can't keep my model within 1 sigma of reality, unlike particle physicists who demand 5 sigma proof, it has to be CO2! If it isn't CO2 I won't have a paycheck!

A grand solar minimum would barely make a dent in human-caused global warming

... a grand solar minimum would offset no more than 0.3°C of global warming...

... So, in order to trigger another "Little Ice Age", a new grand solar minimum would have to cause about 1°C cooling, plus it would have to offset the continued human-caused global warming of 1 to 5°C by 2100, ...

... We're fortunate that the amount of solar radiation reaching the Earth's surface is very stable. Climate contrarians will often ask if we'd prefer if the planet were warming or cooling, suggesting that global warming is a good thing because at least the planet isn't getting colder. This is a false dichotomy - an ideal climate is a stable one.

The relatively stable climate over the past 10,000 years has allowed establishment of human civilization, by making it possible to create large stationary agricultural farms because we could rely on stable weather patterns. During that time, net global surface temperatures changes haven't exceeded 1°C from the coldest to the hottest climates, though we're now approaching that degree of change...

... The science is quite clear that the human influence on climate change has become bigger than the sun's. At this point, speculation about another mini ice age is pure fantasy.


Scientists have a moral obligation to take action on climate change

Calling on all scientists to refrain from public advocacy and leadership is wrong. We are in a global crisis, and the scientific fraternity has an ethical obligation to act

Al Gore’s influential film about climate science was not called A Scientifically-Modelled Truth, or The Statistically Fairly Likely Truth, even though these would have been accurate titles. It was An Inconvenient Truth, because the key factor in the climate debate is not the truthfulness of the science, but the futile political war waged against that scientific truth. That war is still being waged by sections of the media, as well as think tanks and campaigns funded by the polluters...

If the models are within 1 sigma

They aren't. They violated that this year.

There's nothing man can do to stop a mini ice age from occurring unless one
blames us all for causing it in the first place. What I suspect will occur,
if global cooling starts man will not just be blamed for the previous warming
phase but the cooling phase too. Else thousands of scientists dependent on
climate control research will be out of work and in the dole queues.

Nick, you need to understand that Martin is on a lifetime crusade to save the world from itself, and won't hear anything to the contrary.

Shame for he is a nice chappie....

p.s.
your comments waiting in the political thread...

i wonder how most people should place their bets?

So now we are placing bets at the roulette table? Ah, proof it isn't science.

What science of dynamic systems does not use probabilities to predict outcomes?

I think you'll find it's a bit more complicated than that ...

Humans as a species have bottlenecked and during that bottleneck we almost didn't make it. We bottlenecked during the last ice-age.

It has only been during this warm-up that we as a species have grown. Warming has only been a good thing for us and life in general.

When the weatherman gets the 7 day forecast correct I might look a little harder at what the fools say about what too warm would be.

In order to have real science we need to know what the average days weather would be. But in fact we have no idea what average is for a day.

Yep, I deny global warming as something to worry about.

Must not conflict resolve by suggesting that someone should go sit on an ice pick...

You should make;

Yep, I deny global warming as something to worry about.

your epitaph. So that your grandchildren know how to judge you. If you're right then you will have saved them lots of taxes, if you're wrong then maybe you have killed them.

Science is just like politics in the way of too much power is in too few hands.

Your argument is a strawman argument, save taxes or kill our kids by doing nothing.

Logic tells us that the warming is what advanced humans as a species.

Following that logic.

Then shouldn't the countries that lie within the Tropics be the most advanced?

You did NOT follow the logic nor did you read for content, "...advanced humans as a species.", is what I clearly said.

So why are the countries that lie within the warmest parts of the planet not the most advanced then?

Fertile crescent,

Think you need to do some revision on your geography.

I think its not that far from the center belt of this rock and was ice free during the ice age. I'm dang sure of both.

Between 34 degrees East and 48 degrees East. Then between 30 degrees North and 38 degrees North
