The planet's present day greenhouse scourge, carbon dioxide, may have played a vital role in helping ancient Earth to escape from complete glaciation, say scientists in a paper published online today. (Imperial College London press release)

A newly derived, simple law may help scientists improve their climate models and help glaciologists predict where icebergs will calve off from their parent ice sheets, according to a team of researchers. (Penn State press release)

A new picture of the early Earth is emerging, including the surprising finding that plate tectonics on Earth may have started more than 4 billion years ago, new research suggests. (University of California - Los Angeles press release)

New research shows that global warming actually changes the molecular structure of organic matter in soil. (University of Toronto press release)

While global-warming-induced coastal flooding moves populations inland, the changes in sea level will affect the salinity of estuaries, which influences aquatic life, fishing and recreation. (Penn State press release)

A team of researchers has found that plants that range beyond their normal distribution because of warming climates may have advantages over native plants. (University of Florida press release)

Researchers say that radioactive signals are absent in cores they drilled from a Himalayan ice field, indicating that future water supplies could fall far short of what's needed to keep that population alive. (Ohio State University press release)

A detailed analysis of black carbon – the residue of burned organic matter – in computer climate models suggests that those models may be overestimating global warming predictions. (Cornell University press release)

Researchers show that forests may influence the Earth's climate in important ways that have not previously been recognized. (University of New Hampshire press release)

Intense glacial erosion has not only carved the surface of the highest coastal mountain range on earth, the spectacular St. Elias range in Alaska, but has elicited a structural response from deep within the mountain. (Virginia Tech press release)

An unusual microorganism discovered in the open ocean may force scientists to rethink their understanding of how carbon and nitrogen cycle through ocean ecosystems. (National Science Foundation press release)

Scientists may have overcome a major hurdle to calculating how much carbon dioxide is absorbed and released by plants, vital information for determining the amount of carbon that can be safely emitted by human activities. (Carnegie Institution press release)

Researchers simulated conditions in Earth's lower mantle and discovered that the concentration of highly oxidized iron in the two major mantle minerals is key to moving heat in that region and affects material movement throughout the planet. (Carnegie Institution press release)

Researchers have identified a natural phenomenon that may have been the last straw for some Chinese dynasties: a weakening of the summer Asian Monsoons. (University of Minnesota press release)

If climate disasters are to be averted, atmospheric carbon dioxide must be reduced below the levels that already exist today, according to a new study. (Yale University press release)

While Earth has experienced numerous changes in climate over the past 65 million years, recent decades have experienced the most significant climate change since the beginning of human civilized societies about 5,000 years ago, according to a new study. (Cornell University Communications press release)

Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change. (Harvard University press release)

The fight against climate warming has an unexpected ally in mushrooms growing in dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions, a new UC Irvine study finds. (University of California – Irvine press release)
