global warming

On the continental margins, where the seafloor drops hundreds of meters below the water’s surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential energy source, but they are also a potential source of global warming if massive amounts of methane were released during an earthquake or by rising ocean temperatures.

A team of international climate scientists including University of Adelaide's Professor Tom Wigley has today reported further strong evidence of the human influence on climate change.

The East Antarctic Ice Sheet seems to be more vulnerable to the effects of cli-mate change than previously thought. For the first time, an international re-search team from the Universities of Durham and Zurich has studied the long-term development of outlet glaciers using satellite images, revealing that the advance and retreat of the 175 glaciers studied are closely linked to climatic changes.

During heat waves – when ozone production rises – plants' ozone absorption is curtailed, leaving more pollution in the air, and costing an estimated 460 lives in the UK in the hot summer of 2006. Vegetation plays a crucial role in reducing air pollution, but new research by the Stockholm Environment Institute (SEI) at the University of York shows that they may not protect us when we need it most: during extreme heat, when ozone formation from traffic fumes, industrial processes and other sources is at its worst.

The eastern side of the Antarctic Peninsula, a finger of the southern polar continent that juts toward South America, has experienced summer warming of perhaps a half-degree per decade – a greater rate than possibly anywhere else on Earth – in the last 50 years, and that warming is largely attributed to human causes.

Scientists at Lawrence Livermore National Laboratory (LLNL)  and UC Berkeley and have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere.
