We have had seventeen interglacial periods; these are the ten thousand year long intervals between the last four 40 to 100 thousand year long ice ages our planet has experienced. This is a fact. It has been ten thousand years before the start of the current interglacial period. This is also a fact.
The amount of CO2 here on Earth determines the extent of the greenhouse effect; atmospheric conditions determined in part by variable CO2 levels and solar radiation patterns are certainly not finitely predictable over a very long period of time; but there has been a rhythmically predictable pattern to terrestrial temperatures for about the last 1.2 million years. That is a fact.
Beginning in the 16th century there began a Little Ice Age which very well could be interpreted as a sign of the coming ice age. What saved us? It seems to be both solar patterns and huge increases in CO2 and methane in our atmosphere.
If there is another ice age, we will probably not survive as a species. At least all the poor people in third world countries; and all the poor people in capitalist countries. Probably.
Support global warming.
