Centralia, Pa., underground coal fire creeping forward

The Centralia, PA underground coal fire has been burning since 1962 and is still active today. Temperature measurements indicate the fire advances at an average rate of 66 feet per year, with some months showing little movement.

New images from space spotlight regional pollution

Satellite images from NASA's MOPITT project show high levels of carbon monoxide in regions prone to pollution, such as Southeast Asia and Australia. These images provide a new tool for monitoring air quality and tracking the spread of pollutants over long distances.

Amazon wildfires contribute to carbon problem

Amazon wildfires contribute significantly to atmospheric carbon dioxide, reducing tree-life viability to less than half of unburned areas. Dr Barlow's research found that fires damage large, thicker-barked trees, leading to increased emissions and further loss of vegetation.

Past fire regime is key to managing chaparral fires in southern California

USGS scientists Jon Keeley and C.J. Fotheringham argue that natural fire regimes in chaparral ecosystems are not characterized by frequent small fires, but rather by landscape-scale crown fires. They suggest that limited, strategically placed burns are more cost-effective than large-scale prescription burning.

Prescribed burning: Do we really know what we're doing?

Researchers question the efficacy of prescribed burning in reducing large, intense forest fires. They argue that this technique is not suitable for closed-canopy forests and shrublands where natural fires are more frequent and severe. This approach can also have negative ecological consequences.

Fire ant queens and workers negotiate ‘truce' on colony sex ratio

Researchers at North Carolina State University discovered that fire ant queens can alter the sex ratio of their colonies by limiting female eggs laid. This finding suggests a negotiated middle ground between queens and workers, who have competing interests in raising new colony members.

Survival of quaking aspen groves a complex problem

A study by Penn State researchers found that quaking aspen groves have declined by 30% in the last 50 years due to environmental changes such as fire suppression, livestock grazing, and increased herbivore populations. The unique history of the Lake Tahoe Basin also plays a role in this decline.
