Mass Extinction causes Global Climate Change by J. S. Pettingill, published 15 July 2007 page 3 Dust Levels are vastly more important than CO2 It's pretty easy to understand that dust can block sunlight, and have a cooling effect on the planet. But the role of dust is extremely complicated. As one could imagine, dust from different areas or sources will have varying composition and size resulting in different impacts on our climate. A mechanism that links plankton populations with iron dust volumes has been established. Note: The Vostok ice core data (see previous chart) shows that dust level declines always precede a rise in CO2 levels. Dust levels are currently down 99%. While Ocean temperature remains well within normal range as illustrated by the 2.5 million year temperature chart below.
Impacts of dust on climate are one of the least understood components of global weather. Important Comments from the Vostok Dust Analysis "During the late glacial period, changes in the dust composition is characteristic of variations in the strength of the atmospheric circulation, while changes over the last glacial–interglacial transition are indicative of a change in the major dust source areas. The dust characteristics for the glacial and the Holocene periods indicate two different dust types. The glacial dust type partly disappeared after the ACR, while the Holocene dust type appeared significantly after around 16 ka BP and became dominant after the ACR. The relative increase in the Holocene dust type at the glacial–interglacial transition could be due to changed conditions in the potential source area or to changed patterns of atmospheric circulation, resulting in enhanced transport from a source area that was different from the glacial source areas." © 2007 Elsevier B.V.

Present day extinction rates An examination of one ecosystem... "Rainforests Destruction rate: 240 square miles every day. This equals 6417 acres per hour, 107 acres per minute or 1.78 acres per second. This destruction of virgin Rainforests land area causes somewhere between 93 and 1609 Rainforests species Extinctions per day. We believe, based on the Fibonacci series of numbers which are found throughout nature, that there are approximately 560 Rainforests species Extinctions per day." This equals one Rainforests species extinction every 2 minutes and 33 seconds. http://www.hort.purdue.edu/newcrop/tropical/lecture_12/tropical_rainforest_Rl.html
