Document Summary
Right now is a global cooling period, but with human activities altering the movement towards cooler climates instead to a warming. Ice ages had effects on glacial and interglacial climates. Esetimates of volume and global temperature are able to be measured. Long term predictions are that in the next few thousand years the earth will leave its interglacial period and back to the glacial period. This would blanket the northern hemisphere yet again. Short term predictions are the opposite is that the. Pioneers in measuring the atmosphere, looking at co2 and so-on and seeing that each gas could store different amounts of heat. The basic physics of greenhouse gas storage is well known for some time. Arrhenius had calculated the effects of co2 projecting that the doubling of atmosphere greenhouse gas shoud cause a temperature increase of four degrees. The role of co2 in causing glacial and interglacial periods has been well known and well suspected.
