The Dusty Colorado River
September 22, 2010 01:45 PM - Andy Soos, ENN

Snow melt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study by NASA/UCLA shows this is due to increased dust caused by human activities in the typically arid American southwest region during the past 150 years.

Walrus Again Forced to Flee Melting Arctic Sea Ice
September 20, 2010 09:32 AM - Thomas Schueneman, Global Warming is Real

We first reported in 2007 of Walrus pushed off Arctic sea ice due to unusually low Arctic sea ice extent in the eastern Chukchi Sea, where they normally spend their summers breeding and feeding in the shallow waters of the continental shelf. For the third time in the past four years Walrus again find themselves forced onto land due to retreating sea ice.

2010: A Hot Year Indeed
September 17, 2010 02:37 PM - Andy Soos, ENN

Weather is always an easy topic of conversation. The first eight months of 2010 tied the same period in 1998 for the warmest combined land and ocean surface temperature on record worldwide. Meanwhile, the June–August summer was the second warmest on record globally after 1998, and last month was the third warmest August on record. Separately, last month’s global average land surface temperature was the second warmest on record for August, while the global ocean surface temperature tied with 1997 as the sixth warmest for August.

Indian Murky Air Quality

Data from the Multi-angle Imaging Spectroradiometer (MISR) instrument on NASA's Terra spacecraft have been used in a groundbreaking new university study that examines the concentration, distribution and composition of aerosol pollution over the Indian subcontinent. The study documents the region's very high levels of natural and human-produced pollutants, and uncovered surprising seasonal shifts in the source of the pollution.

Killing frost touches western Canada

Killing frosts hit crops in northwestern Alberta on Tuesday, but a widespread frost across the Canadian Prairies looks to arrive a day later than expected, a Canadian Wheat Board analyst said on Wednesday. The frost may have left little damage in the Peace region because wheat and canola crops there are mature enough to withstand it, said Mark Cutts, a crop specialist for the Alberta government. Frost is of particular concern to Western Canadian farmers this year because many crops are one to two weeks behind normal growth, leaving them vulnerable to damage that reduces quality.

Satellite Warning System of Natural Disasters

Looking down upon the Earth gives one the big picture. Up high in the sky are many man made satellites that are designed to look down and send information to various places. NASA is currently designing a pair of robotic probes to keep tabs on how the planet is changing and to help forecasters predict natural disasters, such as volcanic eruptions, earthquakes and landslides.

Fourth Hottest Summer on Record for the United States in 2010
September 14, 2010 10:01 AM - David A Gabel, ENN

As September begins to bring cooler temperatures, Americans can look back objectively at the past summer (June-August). The above average temperatures in the contiguous states combined to make it the fourth warmest ever. Only seven of the lower 48 states had normal temperatures, and 29 were much above normal. This news is detailed in the National Oceanographic and Atmospheric Administration's (NOAA) State of the Climate report issued on September 8, 2010.

China says rich-poor divide still dogs climate pact talks
September 14, 2010 06:25 AM - Reuters, Beijing

The prospects of a new global climate change pact still hinge on resolving the divisions between rich nations and the developing world, a top Chinese climate negotiator said in remarks published on Monday. "Right now there are still huge differences between developed and developing countries in the negotiations on climate change problems," said Su Wei, the head of the climate change office at the National Development and Reform Commission.

Yellowstone Magna

Yellowstone Park is a somewhat dormant super volcano site full of fuming vents and hot geysers. A plume of molten rock rising from deep beneath Yellowstone National Park is probably what is fueling the region's volcanic activity, as well as tectonic plate oddities across the Pacific Northwest, new research suggests.

Methane Reduction from Cattle
September 9, 2010 04:30 PM - Andy Soos, ENN

Methane is a significant green house gas that can lead to global warming. It is also commonly produced by many animals including humans and cattle. Cow belches, a major source of greenhouse gases, could be decreased by an unusual feed supplement developed by a Penn State dairy scientist.
