Historic flooding across large portions of Central and Eastern Colorado has caused an unprecedented amount of damage. Along with the rise in water levels came elevated concern over the tens of thousands of frack wells that scar the region’s landscape. In one of the hardest hit areas, Weld County, there are over 20,000 frack wells…

Via ESA, 11 September 2013: Offering new insights into our fragile polar regions, ESA’s CryoSat mission has provided three consecutive years of Arctic sea-ice thickness measurements, which show that the ice continues to thin. Although satellites have witnessed a downward trend in the extent of sea ice over the last two decades, it is essential to…
Via Phys.org September 11, 2013: Global warming could impact the El Niño Southern Oscillation (ENSO), altering the cycles of El Niño and La Niña events that bring extreme drought and flooding to Australia and many other Pacific-rim countries. New research published in Nature Geoscience using coral samples from Kiribati has revealed how the ENSO cycle has changed…
