The Earth Institute - Columbia University Iceberg the size of Delaware, among biggest ever recorded, snaps off Antarctica A giant iceberg about the size of Delaware that had been under scientists’ watch has broken off from an ice shelf on the Antarctica Peninsula and is now adrift in the Weddell Sea. The 2,200 square-mile, trillion metric-ton section of the Larsen C ice shelf “calved” off sometime between Monday and Wednesday, a team of researchers at Swansea University’s Project MIDAS has reported, citing imaging from NASA’s Aqua MODIS satellite instrument. Scientists have tracked the crack for more than a decade and they warned in June that the section was “hanging by a thread.” Its break, from Antarctica’s fourth-largest ice shelf, changes the border shape of the peninsula forever even though the remaining ice shelf will continue to grow.

Australian Academy of Science The science of climate change: questions and answers An updated edition of The science of climate change: questions and answers will be released in mid-2014. This publication aims to address confusion created by contradictory information in the public domain. It sets out to explain the current situation in climate science, including where there is consensus in the scientific community and where uncertainties exist. What is climate change? The science of climate change: questions and answers was prepared by a working group of nine members co-chaired by Drs Ian Allison and Mike Raupach FAA, FTSE. Low-carbon economy A low-carbon economy (LCE), low-fossil-fuel economy (LFFE),[1] or decarbonised economy[2] is an economy that has a minimal output of greenhouse gas (GHG) emissions into the environment biosphere, but specifically refers to the greenhouse gas carbon dioxide. GHG emissions due to anthropogenic (human) activity are increasingly either causing climate change (global warming) or making climate change worse. Scientists are concerned about the negative impacts of climate change on humanity in the near future.[3] Globally implemented LCEs are therefore proposed by those having drawn this conclusion, as a means to avoid catastrophic climate change, and as a precursor to the more advanced, zero-carbon society and renewable energy economy. Rationale and aims[edit] Nations may seek to become low-carbon or decarbonised economies as a part of a national climate change mitigation strategy. Some nations are presently low carbon: societies that are not heavily industrialised or populated. Smart grid[edit]
Getting rich off global warming On the opening morning of the inaugural National Adaptation Forum, I was eating breakfast at a stand-up table in the exhibition hall when a mustachioed man of middle age plopped his cherry Danish next to my pile of conference literature, a mess of pamphlets and reports with titles like Getting Climate Smart: A Water Preparedness Guide for State Action, and Successful Adaptation: Linking Science and Policy in a Rapidly Changing World. The nametag dangling above the Danish identified the man as Michael Hughes, director of public works for the Chicago suburb of Elmhurst. Like many attendees, Hughes was part of a new national emergency-response team without being fully aware of it. “I hadn’t even heard the term ‘adaptation’ a month ago,” he told me, taking a bite. For three days in April, the downtown Denver Marriot was Mecca for people like Hughes. This was the sound of America’s climate adaptation community coming together at the management level for the first time.
Green News, Energy, Environment, Animals, Climate Change, Extreme Weather - HuffPost Green Gas pipelines supplying Europe 'in real danger from exploding tundra' - top scientist Yerkutinskaya funnel. Picture: Aleksandr Sokolov New analysis by satellite and helicopter shows gas pipelines run right over swelling tundra which is deeply unstable due to the release of underground methane that had been frozen in permafrost - now thawing - for thousands of years, revealed Russia's leading expert on the new phenomenon, Professor Vasily Bogoyavlensky. In one recent explosion, permafrost soil was thrown around 1 kilometre from the epicentre of the blast, highlighting the huge force, scientists discovered. Flames shot into the sky, and a 50 metre-deep crater was formed from the eruption. The process is seen as caused by the warming Arctic climate and has vast implications for the energy industry in polar regions. Seyakhinskaya funnel. Gas from Yamal is crucial to both Russia and the European energy system, with exports in particular to Poland and Germany. Most are harmless but the difficulty for experts is identifying which are dangerous. 'Do you understand?
Sea-level Rise - CSIRO & ACECRC We love the coast. Coastal regions, particularly some low-lying river deltas, have very high population densities. In excess of 150 million people live within 1 metre of high tide level, and 250 million within 5 metres of high tide. There are billions of dollars invested in coastal infrastructure immediately adjacent to the coast. The Oceans are changing. A recent issue of the journal Science has focused on a number of aspects of ocean change, including sea-level rise. A (pdf) reprint of this editorial can be obtained from here. This sea-level rise is a response to increasing concentrations of greenhouse gases in the atmosphere and the consequent changes in the global climate. On this web site, we attempt to bring together information on sea level rise and its causes.

Qué es la COP 15 En diciembre de 2009, todas las miradas estarán puestas en Copenhague (Dinamarca), cuando los gobiernos de todo el mundo se reúnan en la Conferencia de las Partes sobre Cambio Climático de las Naciones Unidas (COP15) para crear el próximo tratado global sobre el cambio climático, que sustituirá al actual Protocolo de Kyoto. Esta reuniónformará parte de un proceso que se inició hace casi 20 años, la Convención Marco de las Naciones Unidas sobre el Cambio Climático (UNFCCC, en sus siglas en inglés). La Convención Marco de las Naciones Unidas sobre el Cambio Climático fue adoptada en Nueva York el 9 de mayo de 1992 y entró en vigor el 21 de marzo de 1994. Permite, entre otras cosas, reforzar la conciencia pública, a escala mundial, de los problemas relacionados con el cambio climático. Para frenar el aumento de la temperatura es necesario estabilizar las concentraciones atmosféricas de CO2 y otros gases de efecto invernadero producidos por el hombre.
