A new breakthrough in hydrogen storage technology could remove a key barrier to widespread uptake of non-polluting cars that produce no carbon dioxide emissions.

The first evidence that recent climate change has weakened one the Earth's natural carbon 'sinks' is published this week in the journal Science.

Carbon dioxide emissions from fossil fuels - the principal driver of climate change - have accelerated globally at a far greater rate than expected over recent years, according to a paper published this week in the Proceedings of the National Academy of Sciences.

President Bush has ordered major government agencies to start work on drafting new regulations to cut dangerous auto emissions. The president is coming under increasing pressure to tackle America's energy woes.

A study released today provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere. Scientists believe the carbon dioxide (CO2) releases helped propel the world into further warming.

A research team, including Kent State Professor of Geology Dr. Joseph Ortiz, tracing the origin of the large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the southern ocean around Antarctica.

Scientists at a UN conference on climate change say nations must make drastic cuts in carbon-dioxide (CO2) emissions in order to limit global warming. The recommendations come in a major report agreed today at a meeting in Bangkok by the Intergovernmental Panel on Climate Change.

Four faculty members from The University of Arizona in Tucson were part of an amicus curiae brief supporting the plaintiff in today's historic U.S. Supreme Court decision on carbon dioxide emissions and climate change.

The European Union's top environment official has lashed out at the United States for not doing enough to cut carbon dioxide emissions. Stavros Dimas, speaking today at the start of a UN conference in Brussels on global warming, said Washington must end its "negative attitude" toward international negotiations on a new climate change pact.
