The Role of Clouds on Earth's Climate
September 7, 2010 10:22 AM - David A Gabel, ENN
Modeling for climate change is an extremely complex process because Earth's climate is so complex. It is an interrelated system that involves the atmosphere, biosphere, land, and oceans. A change in one can cause a chain reaction in all the others. By studying ancient climate change patterns, scientists are better able to predict what might happen in future events. However, one factor that remains far from understanding is the role of clouds — how they will react to and influence a changing climate.
Once More in the Gulf of Mexico
September 3, 2010 02:54 PM - Andy Soos, ENN
The National Oceanic and Atmospheric Administration (NOAA) today reopened to commercial and recreational fishing 5,130 square miles of Gulf waters stretching from the far eastern coast of Louisiana, through Mississippi, Alabama, and the western Florida panhandle. The Mariner Energy oil platform just had an explosion is about 250 miles from today's reopening. The fire on a Mariner Energy Inc. oil and natural-gas platform in the Gulf of Mexico has been extinguished in an event that may prolong the U.S. drilling moratorium imposed after BP's record crude spill.
EPA Disapproves Certain Aspects of Texas' Clean Air Program
September 3, 2010 10:26 AM - David A Gabel, ENN
Every state government has their own agency for the protection of the environment which they operate in conjunction with federal laws and statutes. When those state laws do not match up with their federal counterparts, the potential for conflicts increase. A recent example of this is the Texas Commission on Environmental Quality's (TCEQ) clean-air permitting program. The US Environmental Protection Agency (EPA) has declared that certain aspects do not meet federal Clean Air Act requirements.

Hurricane Earl is still a powerful category four hurricane on the Saffir-Simpson Scale as it approaches the North Carolina coast September 2. NASA's Tropical Rainfall Measuring Mission satellite observed the high rates rain was falling within Earl in some areas more than 2 inches per hour. Hurricane Earl became the most powerful hurricane of the 2010 Atlantic season early on September 2 when its sustained winds reached 120 kts (~138 mph). It was still intensifying when the TRMM satellite passed near its location on 2 September 2010. The TRMM Microwave Imager data were used in the rainfall analysis that showed heavy rainfall, particularly in the northwest quadrant of Earl's very distinct circular eye.

The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. Some of the volcanoes are notable for their eruptions, for instance, Krakatau for its global effects in 1883, Lake Toba for its supervolcanic eruption estimated to have occurred 74,000 Before Present which was responsible for several years of cold of volcanic winter, and Mount Tambora for the most violent eruption in recorded history in 1815. Indonesia's Mount Sinabung has recently erupted, two days after it sprang back into life after over 400 years of inactivity.
Priceless rock art in National Conservation Lands being defaced, destroyed, stolen
September 1, 2010 12:31 PM - Brian O'Donnell, Executive Director of the Conservation Lands Foundation
Ongoing investigations of sites within our National Conservation Lands in the Southwest and southern California are uncovering evidence of cultures and traditions dating back thousands of years. These sites are providing a one-of-a-kind opportunity to research, study, and assess how these different cultures lived and adapted. Something new is being found all the time. Yet, most have never heard about these efforts, let alone the sites and the cultural treasures they contain. One unit within the National Conservation Lands, Canyons of the Ancients in Colorado, has been focal point of these research efforts. It has by far the greatest known concentration of archeological sites in the nation — 6,400 so far -- including cliff dwellings, villages, great kivas, and rock art. But it is not alone.
The Environmentalist’s Paradox
September 1, 2010 10:06 AM - David A Gabel, ENN
The signs are all around. Many places in the world show degradation of the air, water, and soil. Species becoming extinct as natural habitats are being destroyed. The emissions of greenhouse gases that can alter the planet's climate are unacceptable. All the environmental issues put together amount to a very serious threat to human welfare. Yet at the same time, all accepted measures of well-being show that, on average, quality of life is improving around the globe. How does an environmentalist call society into action under such conditions?
The Gulf Slowly Returns
August 31, 2010 05:00 PM - Andy Soos, ENN
The National Oceanic and Atmospheric Administration (NOAA) reopened 4,281 square miles of Gulf waters off western Louisiana to commercial and recreational fishing. The reopening was announced after consultation with FDA and under a re-opening protocol agreed to by NOAA, the FDA, and the Gulf states. On July 18, NOAA data showed no oil in the newly reopened area. Light sheen was observed on July 29, but none since. Trajectory models show the area is at a low risk for future exposure to oil, and fish caught in the area and tested by NOAA experts have shown no signs of contamination.
Study: Horseshoe Crab Decline Connected to Climate Change
August 31, 2010 10:56 AM - David A Gabel, ENN
The horseshoe crab is one of the most ancient animals on the planet today. They have survived massive upheavals throughout the Earth's history and have remained intact and unchanged. Recently their numbers have been in decline, and this is thought to be due to coastal habitat destruction and over-harvesting; they are often used as bait, in fertilizer, or by pharmaceutical companies. However, new research from the US Geological Survey (USGS) indicates that their population size also parallels changes in the climate. With predicted climate change in the future, their numbers may continue to decline.
The Fate of Dairy Antibiotics in Ground Water
August 30, 2010 01:41 PM - Andy Soos, ENN
There are a lot of things that can go into the ground water. The key is whether what goes in will readily biodegrade and if not can it harm you or the environment. In the first large study to track the fate of a wide range of antibiotics given to dairy cows, University of California (UC) Davis scientists found that the drugs routinely end up on the ground and in manure lagoons, but are mostly broken down before they reach groundwater. Note that antibiotics are given to sick cows who are isolated from the regular milking herd until the antibiotic is absent from their system.
