Geotimes February 2007 Sally Adee	Escape From Snowball Earth Early Earth didn't do things half-way: It may or may not have ever been a solidly frozen "snowball" in the deep geological past, but it was never a half-frozen ball of slush, according to a new study.
Chemistry World May 9, 2013 Simon Hadlington	Mineral dust plays key role in cloud formation, chemistry Mineral dust that swirls up into the atmosphere from Earth's surface plays a far more important role in both cloud formation and cloud chemistry than was previously realized.
Geotimes December 2005 Naomi Lubick	Slushball Life Hundreds of millions of years ago, a carapace of ice may have periodically covered the entire planet. New research, however, indicates that microbes seem to have thrived in certain places that they should not have during that time, leading scientists to conclude that the snowball was more slushy than frozen solid.
Geotimes April 2003 Dave Lawrence	Microfossil lineages support sloshy snowball Earth Whether Earth's surface was completely frozen over during the glaciations about 900 to 540 million years ago (a hardball) or experienced open water near the equator (a slushball) is up for debate. Recent research now suggests that slushball conditions were more likely.
Geotimes November 2004 Naomi Lubick	Past warming for the future As the Bush administration prepares for a second term, only time will tell how its climate change policy will change in the next four years. In the meantime, discussions of the science behind climate changes abound in the journals and within the scientific community.
