New calculations indicate the record low minimum extent of sea ice across the Arctic last September has a three-in-five chance of being shattered again in 2008 because of continued warming temperatures and a preponderance of younger, thinner ice. (University of Colorado at Boulder press release)

Scientists have discovered a new climate pattern, the North Pacific Gyre Oscillation which explains changes in the water important in helping commercial fishermen understand fluctuations in the fish stock. (Georgia Institute of Technology press release)

Over millions of years carbon dioxide levels in the atmosphere have been moderated by a finely-tuned natural feedback system – a system that human emissions have recently overwhelmed. (Carnegie Institution press release)

Some light in Earth's aurora glow is polarized – a state not thought possible for the aurora, according to new observations that may improve understanding of Earth's upper atmosphere, its magnetic field, and the energies of particles from the sun. (American Geophysical Union press release)

A much-discussed idea to offset global warming by injecting sulfates into the stratosphere would drastically affect the ozone layer. (NCAR/UCAR press release)

Monitoring Earth's rising greenhouse gas levels will require a global data collection network 10 times larger than the one currently in place in order to quantify regional progress in emission reductions, scientists say. (University of Colorado at Boulder press release)

A full recovery of the stratospheric ozone hole could modify climate change in the southern hemisphere and even amplify Antarctic warming, according to scientists. (University of Colorado at Boulder press release)

Scientists have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought. (Stanford University press release)

Data from faint earth tremors caused by wind-driven ocean waves suggest extreme ocean storms have become more frequent over the past three decades, new research suggests. (Seismological Society of America press release)

Using novel isotopic studies, scientists were able to identify the most important processes responsible for changes in natural methane concentrations over the transition from the last ice age into our warm period. (Helmholtz Association of German Research Centres press release)

Scientists say that Earth's changing jet streams fit the predictions of global warming models and have implications for the frequency and intensity of future storms, including hurricanes. (Carnegie Institution press release)

In a world without human-produced pollution, biological productivity controls cloud formation and may be the lever that caused supergreenhouse episodes during the Cetaceous and Eocene, according to paleoclimatologists. (Pennsylvania State University press release)

Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new study indicates. (University of Virginia press release)

Researchers think there may be a better, cheaper way of determining how powerful a hurricane is – a technique that involves listening for the storms with acoustic sensors. (Massachusetts Institute of Technology press release)

A new, high-resolution, interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren't all from where we thought. (Purdue University press release)

A new study by meteorologists shows that current climate models are quite accurate and can be valuable tools for those seeking solutions on reversing global warming trends. (University of Utah press release)

Researchers at Texas A&M University have confirmed for the first time that a "dead zone" has existed off the Texas coast for at least the past 23 years and will likely remain there, causing potential harmful effects to marine life in the area. (Texas A&M University press release)

New research shows no reliable connection between the cosmic ray intensity and cloud cover, dealing a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases. (Institute of Physics press release)

New research suggests that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. (Rice University press release)

Using state-of-the-art supercomputers, climate scientists have performed a 400-year high-resolution global ocean-atmosphere simulation with results that are more similar to actual observations of surface winds and sea surface temperatures. (DOE/Lawrence Livermore National Laboratory press release)
