If Global warming enthusiasts are right, won't its effects be minimal during the coming ice age?
Every 11,000 years, according to scientists, there is a global ice age. The big ice ages caused what they called "Snowball Earth" where the ice covered the entire surface of the earth including the tropics. Although the research of these scientists indicates this is the climactic history of the earth, they have no idea what caused the ice ages or the subsequent periods of warming, such as the one we are living in now.
One theory is that the earth's orbit around the sun is normally close to a circular orbit, but is thrown into an orbit with a very large aphelion and smaller perihelion, thus causing a majority of the obit to be spent farthest from the warming rays of the sun causing cooler temperatures. Another is that the solar system gyrates in its orbit of the milky way galactic center moving up and down from the galactic plane, and that cycle is 22,000 years. Every 11,000 years we pass through the plane and the sun's light is blocked by a cloud or debris that exists there.
What causes the ice ages is not the issue, the historical data indicates we are due for a new ice age. This would completely devastate the economy of the earth, and wipe out food sources. The only problem is there is no way to blame man for the problem. Perhaps we could get a study going on the opening of refrigerator and freezer doors and how that is contributing to the global cooling. Just a suggestion, then we could tax people who own refrigerators and freezers, and companies that use air conditioning or people who buy ice. There would be a great opportunity for Al Gore to make a movie about the plight of the Siberian Tigers running out of locals to eat because it is too cold.
I am not confusing the 11 year sun spot cycle thanks for the suggestion. I am citing data from several sources including studies of the cyclical nature of climate change and the historical evidence of past ice ages. A major ice age occurs every 105,000 years, and the glaciation appears to increase every 11,000 years. This is from the lake bed evidence scientists have studied and the ice core samples that have been drawn from glaciers and the ice sheets. I believe in a Global Flood to be honest, and I only cite this data to show the hole in the global warming theory. As recently as the 1970's scientists were predicting and warning of a coming ice age. Now it's global warming.

If another Ice age were to come, we will all be praying that the Global Warming enthusiasts are right and wew will REQUIRE ALL electricity come from coal and we will REEQUIRE any activity that produces extra CO2 be increased. Survival of the specicies might be at stake...
(Tongue in check stuff here with some of my answer...)

the theories work in absence of additional greenhouse gases we dug up from the ground. It's not likely that we'll have an ice age with the emissions we're putting up.
climate responds to many factors, and for the last 100, CO2 is a major driver. That CO2 will last for centuries if not more. Saying we can;t have an effect because climate changed before is not understanding the forces. It's also a logic problem- we can't kill people because the die naturally.
BTW, snowball earth occurred 600 million years ago, WAY before people or ice ages. The continents were in different places too.

I think you are confusing the 11 year solar cycle. The Milankovitch cycle results in primarily a 100 thousand year cycle of glaciation. The current interglacial has been milder and longer lasting than the last few before it. It hit its peak 6000 years ago and has generally been cooling since then with some minor cooling and warming periods.
I am more worried about cooling than warming. Maybe our CO2 emissions will have a moderating effect on the natural cooling, whenever that occurs. There are other things that they will fret about such as acidification of the ocean. You can't make an alarmists feel better.

Just because a cycle was a cycle. Doesn't mean it will be a cycle next time. If there have been ice ages in the past every 11,000 years, doesn't mean that we will have one as the 11,000 year mark hits again.
It is, however, more rational to expect the natural cycles to continue than to expect that a trivial human induced change in the amount of CO2 available to the atmosphere will noticeably warm it.

What on earth are global warming enthusiasts?
I'd prefer to be called a warmist rather than an enthusiast as I am not particularly happy about Global Warming.
<<Every 11,000 years, according to scientists, there is a global ice age.>>
According to which scientists?
<<The big ice ages caused what they called "Snowball Earth" where the ice covered the entire surface of the earth including the tropics. >>
"Snowball Earth" occurred approximately 650 million years ago.
"What causes the ice ages is not the issue, the historical data indicates we are due for a new ice age. This would completely devastate the economy of the earth, and wipe out food sources. The only problem is there is no way to blame man for the problem."
The next ice age is not due until some 10,000 years. We should worry about the climate in the next 100 years, not about an ice age in 10,000 years.
<<There would be a great opportunity for Al Gore to make a movie about the plight of the Siberian Tigers running out of locals to eat because it is too cold.>>
Only if:
a) Al Gore is able to survive for another 10,000 years;
b) there's actually any siberian tigers and locals left after global warming severely affects their habitat.
Seriously, try to understand the basics of ice ages of global climate.

You are using a 2005 India Daily editorial hosted at the ExxonMobile funded Frontiers of Freedom think tank for your science?
No wonder you are so misguided.

I suspect that you cannot provide any support for your rather stupid conjecture. "Every 11,000 years, according to scientists, there is a global ice age" is a flat out lie, and you need to go where liars go. You offer a link to a whacko goofy site from 6 years ago that is flat out wrong. Is this where liars get their news?
What do scientists actually say. There's some debate, but the most cited study is Burger 2002 which found that there is nothing in the earth's orbit to cause an ice age for at least 50,000 years.
http://www.sciencemag.org/content/297/5585/1287
An earlier study (Imbrie 1980) concluded that an ice age was at least 23,000 years away, but the more recent Burger calculations are now more believed.
Of course, it is impossible to predict the chemical composition of the atmosphere, and an ice age requires the drop of greenhouse gases as a portion. It's pretty hard to say that there'll be a drop in CO2 in 50,000 years but without that the Milankovitch Cycles cannot cause an ice age.

Mostly I wish that liars would not post their fictitious stuff here. Go post it someplace where people like lies.

An ice age comes about every 100,000 years and a snowball Earth episode occurs every 3/4 to half a billion years.

And a global flood is impossible as there would have to be quit a lot of water appear from nowhere.

firstly ice ages don't happen every 11,000 year and no "Scientists" claim that. If you have a paper that claims this please reference it? Snowball earth is a theory for global ice cover >650 million years ago. It does not apply to today : http://en.wikipedia.org/wiki/Snowball_Earth
Historical data indicates we are probably far overdue and ice age but the fact we arn't in one is probably down to man and the introduction of farming around 6,000 years ago (this was one of the theories anyway).
Global climate change is a natural process. Global warming that is currently occuring is a man made problem as we have pushed the greenhouse effect far beyond what it should be naturally.
