    A real ice ball Earth happened some 700 million years ago. Since then there has been less extreme developments with carbon dioxide production by volcano's, by the oxidation of coal layers, leaking oil and gas etc., while it is absorbed by biological activity that produces coal layers and oil and gas. The carbon dioxide and oxygen content of the atmosphere through the ages has been estimated by geological markers. Most interesting is the development over the last 20 000 years . We can correlate the carbon dioxide content of the atmosphere with the development of the ice cover during that last ice age and also take account of the Milankovitch cycles which show the influence of the changing earth trajectory around the Sun. This shows a change rate of the carbon dioxide that is very much smaller than the current rate due to industrial fuel use. This makes it likely that the temperature will rise at a much higher rate than that at the end of the last ice age. We can expect a higher rate of temperature rise than happened at any time during the last 20 000 years.The climate will then change. Some areas will get dryer, others wetter. That will be a danger to agriculture in the short run and perhaps an advantage in the long run. I would imagine that a large part of Siberia might become valuable agricultural land after very large investment in water control, roads and railways. But before that happens we might have suffered a large famine. Also most people live near the seas and the rise of the sea level will damage a large part of of humankind's investments in cities, ports, industries etc. in the short time of several centuries.

    This is about important World news and it wasn't even mentioned in my dutch newspaper:
    Modi leads India to the Silk Road - Rediff.com India News
    This would change South Asia profoundly. It would have great influence in the Middle East as well as East Asia.

    You forgot to mention the many ice ages:
    850 to 630 million years ago during the Cryogenian period
    460 to 420 million years ago, during the Late Ordovician and the Silurian period.
    The last ice age that occurred 23,500 and 21,000 years ago

    Earth’s climate is controlled by the Sun. In comparison, every other factor is trivial. The coldest part of the Little Ice Age during the latter half of the seventeenth century was marked by the nearly complete absence of sunspots. And the Sun now appears to be entering a new period of quiescence. August of 2008 was the first month since the year 1913 that no sunspots were observed.

    We have heard much of the dangers of global warming due to carbon dioxide. But the potential danger of any potential anthropogenic warming is trivial compared to the risk of entering a new ice age. Public policy decisions should be based on a realistic appraisal that takes both climate scenarios into consideration.

    There is no evidence of increased severe weather events anywhere in the world. Statistically, the world weather is doing what it has always done. What really amazes me is when one sees a TV reporter interviewing some old farmer and the interview goes like this: “Hello, your farm is covered waist deep in snow; is this bad for you!” “Farmer: “Yes it is, it is killing my animals.” Reporter: “Do you think this is due to climate change?” “Oh yes,” says the farmer. “I am sure it is.”

    Then the reporter says: “Have you ever seen it this bad before?” The farmer replies: “Well not for a long time; this is as bad as the 1972 snowfall, but not as bad as the 1966 fall.” Nobody then points out that if there was a 1972 snowfall as bad, and one in 1966 which was worse, and then you cannot possibly attribute the current one to climate change. This fundamental piece of logic is never followed up by the reporters.

    Even the IPCC, which is not known for having balanced views, or even scientific views, has recently admitted that there has been no global warming for the past 16 years. That is worth repeating; no global warming 16 years!

    It appears strongly as if all the observed global warming and cooling, for thousands of years, can be explained by cosmic rays from outer space interacting with the magnetic field effects of the magnetic fields of the Sun and the Earth. The observed effects fit the physics of the magnetic field theory well; it does not fit a CO2 theory.

    The variation in the power of the Sun is small compared with the slow secular increase in that power and is not the explanation of the ice ages. The ice ages are caused by variation in the orbit of the Earth around the Sun ( Milankovitch ), the production and absorbtion of carbon dioxide and other greenhouse gasses ( water vapor is even more important ) and the distribution of sea and land areas determining climate. Production and absorbtion of carbon dioxide is dependent on biological activity and plate tectonics. Biological activity is dependent on everything. Most of these things vary very slowly. An exception was the break out of a large lake in North America when an ice dam failed some 11000 years ago and a large amount of fresh water reach the North Atlantic. Others must have been the inundation of the Mediterranean after it had been closed of from the ocean during ice ages during which layers of salt formed on its bottom and the inundation of the Black Sea. Such episodes lasted days or weeks. The break out of the North American lake caused a drop in average temperature in a small lake near the border of Germany and France of some 10 degrees during a time of less than 15 years. This hiccup in the warming at the end of the last ice age lasted some 500 years.
    The one effect caused by the Sun was the drop in activity during the Maunder minimum which is thought to have caused the Little Ice Age of the 17th century. But that effect has now died out and cannot be the explanation of ice ages lasting ten or hundreds of thousands of years. The current increase in average world temperature is best explained by the increase in cabon dioxide in the air. Even so there are plenty of short term effects, El Nino, volcanic eruptions etc., that make it impossible to predict accurately the average temperature from the carbon dioxide content of the air.

    I knew you guys were old, but your eye-witness account of the planets history explains some of your "crusty-ness"
    as well, I'll proclaim myself a young earth creationist, and leave it at that.

    It's the grey hairs that give it away, right?

    Quite OT
    I remember my mother saying to me when I was 36: "You're starting to gray", and my answer was: "Not all all. I've been graying for the last 15 years."

    World News is meant for truly breaking world news. Tragedies, disasters, major events, outbreak of war, well known leaders or people dieting, etc.

    NOT political news regarding taking swipes at particular ideologies or thoughts...on either side.

    We can all find such articles written to reinforce this or that political or ideological persuasion, but That is not what SD is for or about.

    That is all.

    Do not respond to this moderation.
