According to the NAU researchers, the warming that occurred in the 20th Century and early 21st Century, “contrasts sharply” with the millennial-scale cooling trend; the last half-century being the warmest in the record, and, the decade from 1999 - 2008 being the warmest decade of the last 200 decades. Over all average temperatures were 1.4° C (about 2.5° F) warmer than the projected value based on the linear cooling trend.

An interview with and climate scientist and oceanographer Dr. Julian P. Sachs. quote from the interview: “The increase in atmospheric CO2 and methane since about 1850 are unprecedented in the last 800,000 years in terms of the amount and rate. High levels of these gases in the atmosphere in the geologic past (last 800 kyr there is excellent data from ice cores) have always been associated with warm temperatures, and vice versa. It is not a stretch to [...]

The discovery of ancient human burial site in Niger, Africa last Summer (by Paleontologist Paul Sereno, Univ. of Chicago) with graves possessing numerous artifacts and and even plant fibers and seeds, was indirect confirmation of what scientists have long known: that the Sahara region was once a lush, lake-strewn region hospitable to many early human groups. in addition, many other larger fauna, like hippos, populated the area.

How this transition to a most inhospitable, arid desert (known as desertification) occurred, and [...]
