NASA looks at Tropical Storm Jebi in South China Sea Tropical Storm Jebi developed on July 31 and NASA satellite data on Aug. 1 shows the storm filling up at least half of the South China Sea. Contact: Rob Gutro Public Release: 1-Aug-2013
NASA sees Hurricane Gil being chased by developing storm On July 31, NASA's TRMM satellite saw Tropical Storm Gil intensifying and the storm became a hurricane. NASA's Aqua satellite and NOAA's GOES-15 satellite captured views of Gil on Aug. 1 as it was being chased by another developing tropical system. Contact: Rob Gutro Public Release: 1-Aug-2013
NASA seeing which way the wind blows The autonomous and compact High-altitude Imaging Wind and Rain Profiler, or HIWRAP, a dual-frequency conical-scanning Doppler radar, will hang under NASA's aircraft's belly as it flies above hurricanes to measure wind and rain and to test a new method for retrieving wind data.

UCI-led team develops more accurate model of climate change's effect on soil Scientists from UC Irvine and the National Center for Atmospheric Research have developed a new computer model to measure global warming's effect on soil worldwide that accounts for how bacteria and fungi in soil control carbon.

Cool heads likely won't prevail in a hotter, wetter world Researchers from Princeton University and the University of California-Berkeley report that even slight spikes in temperature and precipitation greatly increase the risk of personal and civil violence, and suggest that more human conflict is a likely outcome of climate change.

Geoscientists unearth mineral-making secrets potentially useful for new technologies Proteins have gotten most of the attention in studies of how organic materials control the initial step of making the first tiny crystals that organisms use to build structures that help them move and protect themselves. Virginia Tech researchers have discovered that certain types of sugars, known as polysaccharides, may also control the timing and placement of minerals that animals use to produce hard structures.

Extreme wildfires likely fueled by climate change Climate change is likely fueling the larger and more destructive wildfires that are scorching vast areas of the American West, according to new research led by Michigan State University scientists. Contact: Andy Henion Public Release: 1-Aug-2013
Climate change occurring 10 times faster than at any time in past 65 million years Not only is the planet undergoing one of the largest climate changes in the past 65 million years, Stanford climate scientists report that it's occurring at a rate 10 times faster than any change in that period. Without intervention, this extreme pace could lead to a 5-6 degree Celsius spike in annual temperatures by the end of the century. Contact: Noah Diffenbaugh Public Release: 1-Aug-2013
As climate, disease links become clearer, study highlights need to forecast future shifts Climate change is affecting the spread of infectious diseases worldwide, according to an international team of leading disease ecologists, with serious impacts to human health and biodiversity conservation. Writing in the journal Science, they propose that modeling the way disease systems respond to climate variables could help public health officials and environmental managers predict and mitigate the spread of lethal diseases.

Future warming: Issues of magnitude and pace Researchers reviewed the likelihood of continued changes to the terrestrial climate, including an analysis of a collection of 27 climate models. If emissions of heat-trapping gases continue along the recent trajectory, 21st century mean annual global warming could exceed 3.6 °F ( 2 °C) over most terrestrial regions during 2046 to 2065 and 7.2 °F (4 °C) during 2081-2100.At this pace, it will probably be the most rapid large climate change in the last 65 million years.

Climate strongly affects human conflict and violence worldwide, says study Shifts in climate are strongly linked to human violence around the world, with even relatively minor departures from normal temperature or rainfall substantially increasing the risk of conflict in ancient times or today, according to a new study by researchers at the University of California, Berkeley, and Princeton University.

Arctic sea-ice loss has widespread effects on wildlife How the Arctic wildlife and humans will be affected by the continued melting of Arctic sea ice is explored in a review article in the journal Science, by an international team of scientists. The article examines relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus; as well as the effects of human exploration of previously inaccessible parts of the region.

Satellite sees Flossie fizzle fast Tropical Depression Flossie fizzled fast on July 30 in the Central Pacific Ocean. Satellite imagery on July 31 showed remnant clouds northwest of the Hawaiian Island chain. Contact: Rob Gutro Public Release: 31-Jul-2013
NASA finds powerful storms in quickly intensifying Tropical Storm Gil No sooner had Tropical Storm Flossie dissipated then another tropical cyclone called Tropical Depression 7E formed yesterday, July 30, in the eastern Pacific Ocean. NASA's TRMM satellite saw "hot towers" in the storm's center early on July 31, that indicated it would likely strengthen, and it became Tropical Storm Gil hours later.

Ancient whale coprolites, fault slickensides, shergottites, Ediacara, and Cascadia Two new Geology articles this month are open access: "Steady rotation of the Cascade arc" and "Silica gel formation during fault slip: Evidence from the rock record." Other new articles cover everything from the discovery of fossilized whale "intestinal products" in central Italy to flooding as a result of the 2010 Eyjafjallajökull volcano eruption to new findings via the Compact Reconnaissance Imaging Spectrometer for Mars to using microfossils to reconstruct massive earthquakes in Cascadia.

Navy turns to UAVs for help with radar, communications Scientists recently launched unmanned aerial vehicles from a research vessel in a significant experiment that could help boost the Navy's radar and communications performance at sea. Contact: Peter Vietti Public Release: 31-Jul-2013
Sediment trapped behind dams makes them 'hot spots' for greenhouse gas emissions With the "green" reputation of large hydroelectric dams already in question, scientists are reporting that millions of smaller dams on rivers around the world make an important contribution to the greenhouse gases linked to global climate change. Their study, showing that more methane than previously believed bubbles out of the water behind small dams, appears in ACS' journal Environmental Science & Technology.

Southerners are less trusting, but trust is a factor in environmental cooperation, study shows Southerners are generally not as trusting as people who live in other parts of the country, but trusting people are more likely to cooperate in recycling, buying green products and conserving water, a new Baylor University study shows.

Could planting trees in the desert mitigate climate change? As the world starts feeling the effects of increasing atmospheric carbon dioxide and consequent global temperature rise, researchers are looking for a Plan B to mitigate climate change. A group of German scientists has now come up with an environmentally friendly method that they say could do just that. The technique, dubbed carbon farming, consists in planting trees in arid regions on a large scale to capture CO2. They publish their study today in Earth System Dynamics, a journal of the European Geosciences Union. Contact: Bárbara Ferreira Public Release: 31-Jul-2013
'Highway from hell' fueled Costa Rican volcano In a new study in the journal Nature, scientists suggest that the 1960s eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought.

Sequestration and fuel reserves A technique for trapping the greenhouse gas carbon dioxide deep underground could at the same be used to release the last fraction of natural gas liquids from ailing reservoirs, thus offsetting some of the environmental impact of burning fossil fuels. So says a paper to be published in the peer-reviewed International Journal of Oil, Gas and Coal Technology. Contact: Albert Ang Public Release: 30-Jul-2013

Radio waves carry news of climate change Prof. Colin Price of Tel Aviv University has discovered that radio waves reflecting back to earth from the ionosphere can offer valuable news about the extent of climate change. His simple, cost-effective measurement can be a valuable contribution to the ongoing effort to track climate change, adding to current measurements for a more holistic picture.
