GRAPH: 400,000 Years of Warmal Colding

In the extremely unlikely event that anthropogenic (human-caused) global warming is actually occurring, it may be rescuing us from another Ice Age:

...in terms of the geologic time scale, human history is the blink of an eye compared the 4.5 billion year age of the earth. The end of the last ice age, a monumental, undeniably non-anthropogenic warming event, happened about 12,000 years ago; to a geologist it may as well have happened a week ago last Thursday. Yet climate scientists rarely address the implications of that warming event on their modern-day warming theories.

But this week, a new study came out which alarmingly concludes that CO2-forced temperatures are at or near their Holocene (post ice age) maximum... data from the Vostok Ice Core ... affords a look at the last 400,000 years of earth history, encompassing several ice ages.

...The top graph shows CO2 concentration in the atmosphere; the bottom one shows average temperature departure from the 1950 value. Two observations are readily apparent:

• For the last 400,000 years at least, "normal" = "COLD!"

• The warm periods are but brief interludes between ice ages. Wild temperature fluctuations were common before any possible impact of human civilizations. The anomaly is the stability of the moderate temperatures during the Holocene, the last 12,000 years (indicated by my red arrow), when warm weather fostered the development of human agriculture, cultures and civilization.

Consider what a global ice age would mean. Cincinnati, OH and points north would be under a glacier hundreds of feet thick (not necessarily a bad thing, in the mind of some readers and SEC football fans). Agriculture would be impossible in North America. The planet could sustain a tiny fraction of its current population.

Given the writings of the more extreme Climatards (which is the term they prefer, I hear), eradication of the "Human Virus" is the goal.
