Earth's huge 'snowball event' (BBC Online 8/28)
When Earth Was a Snowball... (ABC News 8/27)
"A research team from Harvard University in Massachusetts has proposed that a fall in the level of carbon dioxide in the earth's atmosphere 750 million years ago caused a drop in global temperatures which came close to wiping out all life on earth."
A quest for fire (Nature Science Updates 8/27)
"A long-term analysis of the record of wildfires in sub-Saharan Africa shows up a distinct anomaly: the past 10,000 years have been the most fiery in the past million. "
Researchers Assess Biological Potential Of Mars, Early Earth And Europa (Science Daily 8/26)
"Professor Bruce Jakosky of CU's Laboratory for Atmospheric and Space Physics and Professor Everett Shock of WU's Department of Earth and Planetary Sciences modeled geochemical reactions from rock weathering. They also estimated Martian volcanic activity over time and the associated activity of hydrothermal vents. They concluded a surprisingly small amount of life could have been produced through chemical reactions over billions of years."
Geologist Finds Evidence That Mass Extinctions Are Not Unique In Affecting Global Diversity Trends (Science Daily 8/24)
"Miller's evaluation of global marine diversity patterns through the Phanerozoic, in light of recent research, indicates that mass extinctions are simply the most globally extensive of a continuum of abrupt transitions that combine to affect overall global diversity."
Scientific Team Returns From Tsunami Site (Science Daily 8/24)
"The first scientific team to survey and report on last month's catastrophic tsunami at Sissano Lagoon in northwestern Papua New Guinea suggests that tsunamis, or tidal waves, may threaten more coastline regions of the world than previously thought, including much of the West Coast."
A New Martian Meteorite Found In The Sahara (Science Daily 8/19)
"This meteorite is the first Martian meteorite found in the hot desert climate of the Sahara. It is the first one found since 1994 and also the first since the discussion whether there is life on Mars began two years ago. Now, the number of Martian meteorites has increased to a total of 13, a small number if compared to the total of more than 20,000 meteorite specimens known so far."
Sudden Climate Warming Took Place 2,000 Years Ago (Science Daily 8/19)
"A sudden warming of climate lasting several centuries took place in equatorial Africa some 2,000 years ago, according to a new study reported by a Weizmann Institute of Science-led team in the August 14 issue of Science."
Duke Studies Show U.S. Central Plains Vulnerable To Global Warming (Science Daily 8/14)
"By analyzing how the northern U.S. Central Plains changed between grassland and forest due to past climate changes, Duke University ecologists have offered further evidence that the region will likely undergo drastic ecological changes due to 21st-century global warming."
Two Dinosaur Eggs Believed Discovered in Bolivia (CNN/Reuters 8/13)
"Scientists said on Wednesday they had found what were thought to be two dinosaur eggs in southern Bolivia in what could be one of the biggest fossil fields in the world."
Oil spills into sea near Peru wildlife reserve (CNN/Reuters 8/12)
"An oil slick on Peru's southern coast threatened a seal reserve and bird sanctuary on Wednesday after a spill from a pipe that juts into the sea to load ships with crude, authorities said. "
Experts blame floods, heatwaves on global warming (CNN/Reuters 8/12)
"Flash floods kill thousands in Asia, the death toll from heatwaves in Mediterranean Europe soars. And experts say it's all due to global warming and demand urgent action."
U.S. Opens North Slope to Drilling (Washington Post/AP 8/6)
"Seeking a balance between oil development and the environment, the Clinton administration announced today it will open nearly 4 million acres of a federal reserve on Alaska's North Slope to oil development."
