Did the ice age affect just the Northern hemisphere?

mainly cloudy with occasional showers and a north easterly prevailling wind

The glacial advances of the last million or so years, which is what is generally meant by the "Ice Age" if the term is used without qualification, occurred in both the southern and northern hemispheres. The landforms seen in Britain and America for example, that give evidence of former ice cover are also seen in Tasmania, the Snowy Mountains of mainland Australia and southern Patagonia. The Antarctic ice sheet almost certainly spread across the Southern Ocean as an ice shelf, but because there is no land there, we don't see much evidence.

Glaciation didn't just happen at mid- or high latitudes either; there is similar evidence of glacial advance in the higher mountains on the New Guinea island, not far from the Equator.

the last ice age ended about 10,000 years ago, and mainly affected the northern hemisphere. North America and Europe were buried under extensive ice sheets. Antarctica, while occupying the polar region has always been under an ice cap, which extends in winter forming vast amounts of sea ice. Southern land was not affected in the same way as the north.

Further back in time, there is evidence of a snowball earth which was brought about by many factors, including the breakup of the old red continent which would increase weathering and a reduction of CO2 along with the earths orbital path which may have dramatically reduced temperatures.

There have been more than one ice age in geologic history. In general though it is safe to say that during an ice age you will find polar ice sheets at both poles. If you look at wikipedia under ice age you will see that the position of the continents has a lot to do with the likelihood of an ice age. So to answer your question, no the northern hemisphere was not solely affected, but due to the greater amount of landmass in the North the effect was greater.

The ice age affected the Southern Hemisphere just like the Northern. In fact, it still does. The southernmost continent, Antarctica, is still in the grip of this ice age.

It affected all the world because if you look in museums you find ice creatures only found in the southern hemisphere.

because of the tilt of the earths axis the southern hemisphere actually experiences more intense seasonal weather. the summers are a little hotter and the winters are a little colder. i don't know of any data that exists that would show climactic changes in something other than a tilted axis earth. for all we know the earths axis may have been tilted from the dawn of its existence.

no person quite knows if worldwide warming simply by guy is even happenning!!! Scientists even argue the element. some say it quite is because of the fact the earth's orbit shifts closer then greater advantageous removed from the sunlight each and every maximum of thousand years. some scientists say the pollution will finally cool the planet, reflecting image voltaic away. some supply the freezing or the boiling result credence. None can supply absolute medical actuality approximately any of those theories, and thats all they are is theories.

Well if you watched a t.v. programme the continental strata was one central mass around the equator, following a seismic eruption the parts separated and form the shelves that we know as continents of America,Asia, Africa, and Oceania.I certainly would not want to have been around weather wise during that period!

pretty dodgy to begin with very very cold.
