The Arctic Ocean could be nearly ice-free in 30 years—60 years sooner than was previously predicted, according to a paper published last week by the American Geophysical Union. The new projections, which appear in the April 3, 2009, Geophysical Research Letters, are based on data from six global-climate models most suited for assessing sea ice, according to University of Washington climate scientist Muyin Wang and James Overland, an oceanographer with the National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory in Seattle.

Update: Protest G20 in Londra foto
Within days, world leaders are meeting at the London G20 Summit to tackle the global economic crisis — we desperately need them to agree to invest in a green recovery and a bold global rescue package of stimulus, regulation and fundamental reform. Continue reading
Alexandria, 11th of May, 2008. It is the second day of international conference on evaluating of climate change and development. The measure which was organized by Global Environment Facility together with Bibliotheca Alexandrina get together 150 evaluators, specialists and consultants from GEF, different development agencies and banks, academists and NGOs’ representatives from more than 20 countries to discuss issues and problems of present approaches and tools of evaluation of projects, program and policies.

Climate change could cause severe crop losses in South Asia and southern Africa over the next 20 years, a study in the journal Science says. Continue reading
Global warming is happening and some people still think it’s not happening which is just fine, but even they have to admit the climate is changing. The planet is constantly altering, we have to decide what we will do to adapt. Animals and plants are already changing the way they act by blooming and migrating sooner. Continue reading
Climate change, a recent “hot topic” when studying the atmosphere, oceans, and Earth’s surface; however, the study of another important factor to this global phenomenon is still very much “underground.” Few scientists are looking deep enough to see the possible effects of climate change on groundwater systems. Little is known about how soil, subsurface waters, and groundwater are responding to climate change. Continue reading

LONDON – Global warming is drying up mountain lakes and wetlands in the Andes and threatening water supplies to major South American cities such as La Paz, Bogota and Quito, World Bank research shows. Continue reading
The last Sunday in July is International Bog Day, an annual event that celebrates the beauty of bogs and raises awareness of the need to conserve them. Although bogs take about 10,000 years to form, as much as 96% of them have been destroyed since 1945. Worse still, damaged bogs emit large quantities of greenhouse gases such as carbon dioxide, methane and nitrous oxides. As a bog’s peat decomposes, these gases are released. Conversely, healthy bogs absorb carbon, and as such can be an ally in the struggle to reduce carbon emissions. For all these reasons, one LIFE project is working hard to restore bogs in Wales.
The LIFE Active Blanket Bog project (LIFE06 NAT/UK/000134), launched last August, is to last five years restoring blanket bogs in the Berwyn and Migneint special areas of conservation (SAC). Blanket bogs are areas of wet peat-land that are fed exclusively by rainwater. Peat is a waterlogged soil that is composed of compacted, partially decomposed vegetable matter. Although large areas of blanket bog still occur in Wales, the majority have been seriously degraded through afforestation, encroachment by alien species, over grazing, drainage, and either deliberate or accidental burning.
The Berwyn South Clwyd Mountains and Migneint Arenig Dduallt are two of the most important SACs for blanket bog in the UK. Most of the former site and all of the latter site are also designated as SPAs for their breeding upland bird populations. However, in the 1920s and 1930s, farmers dug ditches in and around the blanket bog to improve the agricultural value of the land. Extensive areas of blanket bog and other habitats in the Berwyn and Migneint uplands were also planted with Sitka spruce (Picea sitchensis) in the 1970s and substantial areas have been invaded by rhododendron (Rhododendron ponticum) and Sitka spruce seedlings.
The Active Blanket Bog project will remove Sitka spruce and rhododendron bushes from the bogland areas and institute practical restoration and conservation actions. The restoration work will take place over a total area of more than 4,500 ha. Drainage ditches will be blocked in and around blanket bog on moorland within the Berwyn and South Clwyd Mountains SAC. In each year of the project, an estimated 18km of drains will be blocked, mainly by using heather bales to create dams. Over the lifespan of the project, a total of 91km of drains will be blocked. Heather mowing will also take place to create firebreaks to help protect the blanket bog from fire.
This LIFE-funded project is a partnership between the Royal Society for the Protection of Birds, Countryside Council for Wales, Environment Agency Wales, and Forestry Commission Wales.
Yesterday, thick among the gleeful, chanting, throngs of Live Earth, I had to make a decision; fight my way in and out of the crowds to my computer or listen to Ludacris. In the end, I let the music win.
