Gerard LeBlond for redOrbit.com - Your Universe Online A team of scientists from Reno, Nevada’s Desert Research Institute (DRI), led by Michael Sigl and Joe McConnell, has reconstructed historic volcanic sulfate emissions from the Southern Hemisphere. It is considered to be the most accurate and defined reconstruction to date, and was published in a manuscript in the online addition of Nature Climate Change. Included in the study and submitting ice core samples and measurements, were...

Understanding A Century Of Human Impact On Arctic Climate

Desert Research Institute The Arctic is the most rapidly warming region of the globe, but warming has not been uniform and the drivers behind this warming not fully understood even during the 20th century. A new study authored by Canadian and American investigators and published in Scientific Reports, a primary research publication from the publishers of Nature, suggests that both anthropogenic and natural factors – specifically sulphate aerosols from industrial activity and volcanic...

April Flowers for redOrbit.com - Your Universe Online A pioneering new study, which included scientists from the Desert Research Institute (DRI), The University of Illinois at Chicago (UIC), and Michigan State University among others, has revealed for the first time a viable community of bacteria that survives and ekes out a living in a dark, salty and subfreezing environment. This community is beneath over 65 feet of ice in one of Antarctica's most isolated lakes; Lake Vida. The...

First such levels measured outside polar regions In Hebrew, the Dead Sea is called Yam ha-Melah, the "sea of salt." Now measurements show that the sea's salt has profound effects on the chemistry of the air above its surface. The atmosphere over the Dead Sea, researchers have found, is laden with oxidized mercury. Some of the highest levels of oxidized mercury ever observed outside the polar regions exist there. The results appear in a paper published on-line November 28th in the journal...

A state water authority manager suggests providing public funds for seeding clouds in Northern Nevada for drinking water in Las Vegas. Southern Nevada Water Authority General Manager Pat Mulroy suggested his agency provide funds to keep a Desert Research Institute cloud seeding program operating, The Las Vegas Sun reported Monday. Water authority staff members must determine whether it would be in southern Nevada's best interest to fund part of the cloud-seeding program, so the DRI could...

The burning of coal in North America and western Europe has been a prime contributor to heavy metal pollution in the Arctic, according to a new study. Scientists from the Desert Research Institute measured levels of cadmium, lead and thallium in a Greenland ice core and found them to be linked other chemicals that point to coal as the origin. These chemicals accumulate in the bodies of plants and animals that live in the region.  Some Arctic caribou, whales, polar bears and even humans...

By Alex Breitler From his offices in Fresno, Steve Johnson explained how cloud seeders spent one of the driest Januaries on record: "We'd look at the forecast maps and pray," he said. Johnson's planes are soaring over the Sierra Nevada once again this week, scattering silver iodide particles to squeeze just a bit more snow out of some long-awaited storms. The twin-engine planes have been frozen to the ground for the most part this winter, said Johnson, general manager of Atmospherics Inc.,...

By England, Glenn C; Watson, John G; Chow, Judith C; Zielinska, Barbara; Et al ABSTRACT With the recent focus on fine particle matter (PM^sub 2.5^), new, self-consistent data are needed to characterize emissions from combustion sources. Such data are necessary for health assessment and air quality modeling. To address this need, emissions data for gas-fired combustors are presented here, using dilution sampling as the reference. The dilution method allows for collection of emitted...
