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 [...]
This month, as the results of data analyses come in, climate scientists are getting a more detailed, far clearer picture of the ‘State of the Poles’ and the effects of warming and climate change in these most extreme regions of our planet. Although this project is actually the culmination of two years work (encompassing 160 separate studies and costing 1.2 billion dollars) it has been officially deemed the ‘International Polar Year’ (IPY).
One of the most important findings of this project is a confirmation of what many climate scientists have suspected for a couple of years now–that the impact of climate change on our environment is happening at a much faster rate than previous computer models predicted. This is true even for the four major reports released by the Intergovernmental Panel on Climate Change (the last of which was released in 2007).
