The first evidence that millions of tons of a greenhouse gas 20 times more potent than carbon dioxide is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists.

wenn dem so ist, wie kommt dann die enorme gletscherschmelze zustande?
26.09.2008, 09:10
naja woher weisst du dass es ne gletscherschmelze gibt? greenpeace is ja auch son verein der sich lieber mit dem töten von walen auseinandersetzt, obwohl themen wie biosprit, dessen produktion auf die kosten der der menschheit verfügbaren nahrungsmittelmenge geht, viel interessanter wären, aber komischerweise nur EX-greenpeace-mitglieder sich überhaupt wagen, dazu ne rationale äusserung zu bringen. immerhin ist es erwiesen von der nasa (nicht weniger vertrauenswürdig als greenpeace), dass die eisfläche der arktis, im gegensatz zu spekulationen der scare-monger gewachsen zwischen 2007 und 2008 ist und nicht gesunken. blablabla
und ausserdem wie erklärst du dir eine klimaerwärmung, wenn gleichzeitig sowas (schnee in südafrika) um diese zeit passiert?
es gibt ne menge gletscher ausserdem die ne menge mehr eis tragen als vorn paar jahrzehnten... das einzige was evtl. von statten geht is ne klimaverschiebung, klimatausch, aber keine allgemeine erwärmung.. .und wo die wohl her kommt... entweder natur oder mensch aber nix mit co2
edit: vielleicht schmelzen ja manche gletscher, weil sie zu nah an den chemiestreifen sind? *g*
Gletscher sind beeindruckende Indikatoren für die immer dramatischer werdenden Auswirkungen des Klimawandels - sie sind die Fieberthermometer unserer Erde.
(LK) Aktuelle Messergebnisse belegen: Die Dachstein-Gletscher schmelzen im Rekordtempo - Start für eine engagierte Klimaschutzoffensive. Neues Forschungsprojekt belegt nicht nur zunehmendes Abschmelzen in der Länge, erstmals wurde am Dachstein auch die Veränderung des gesamten Eiskörpers also auch die Änderung in der Dicke des Eises untersucht und eine Massenbilanz für ein gesamtes Gletscherjahr erstellt.

Google TechTalks January 27, 2006 Thomas C. Heller and Stephen H. Schneider Abstract Please join two distinguished Stanford Professors, Dr. Stephen Schneider and Professor Thomas Heller, for a discussion on climate change and the emerging carbon trading markets. Dr. Schneider is one of the world's leading scientific experts of climate change (his name is cited on all those climate change charts and graphs we've seen so far). Dr. Heller has extensive experience with policy and negotiations surrounding climate change and sustainable development. Professor Heller also recently served as Sergey's host at the recent UN Climate Change Conference meeting in Montreal where Prof. Heller proved his indepth knowledge of thenuances of legislative works, such as the Kyoto Protocol, and the mechanisms that are currently being employed. This tech talk will be different than our previous climate change talks. These men have helped steered the international course of policy, scientific verifications and the overall consensus on the existence of climate change. They both have plenty to say about what the failures and successes have been along the way, and what their predictions for the future of climate change policy will be.

There is much discussion of the dangers of climate change, but what is the scientific basis for the predictions? This talk will review the science behind the headlines. Dr Emily Shuckburgh is a Fellow in mathematics at Darwin College and a Natural Environment Research Council Fellow based at the British Antarctic Survey. She is involved with the media, regularly contributing to discussions of climate change and other environmental issues. (Photograph courtesy of Howard Guest.)
The Intergovernmental Panel on Climate Change (IPCC) was jointly established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) in 1988. Its terms of reference include (i) to assess available scientific and socio-economic information on climate change and its impacts and on the options for mitigating climate change and adapting to it and (ii) to provide, on request, scientific/technical/socio-economic advice to the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). From 1990, the IPCC has produced a series of Assessment Reports, Special Reports, Technical Papers, methodologies and other products that have become standard works of reference, widely used by policymakers, scientists and other experts.
This volume, which forms part of the Third Assessment Report (TAR), has been produced by Working Group I (WGI) of the IPCC and focuses on the science of climate change. It consists of 14 chapters covering the physical climate system, the factors that drive climate change, analyses of past climate and projections of future climate change, and detection and attribution of human influences on recent climate.

Climate change has multiple direct and indirect consequences for human health. Heat waves affect health directly and are projected to take an increasing toll in developed and underdeveloped nations. The 2003 summer heatwave in Europe -- an event six standard deviations from the mean -- led to 21-35,000 excess deaths in five nations, extensive wildfires, crop failures, nuclear plant shutdowns and melted 10% of the Alpine glacial mass. This event and Hurricane Katrina in 2005 demonstrate that climate change and its impacts may be surprisingly non-linear. Credits: Speaker:Paul Epstein

How is human activity changing the climate and what are the consequences? Is global warming the cause of more frequent droughts, stronger storms and less snow in the mountains? Lawrence Livermore National Laboratory Scientist Dave Bader explores what scientists know about climate change and the research tools used to study the climate. Series: Science on Saturday [10/2006]

For the Inuit, climate change is an issue of cultural survival. Join Sheila Watt-Cloutier, Chair of the Inuit Circumpolar Conference (ICC), an organization representing the Inuit across the Arctic, as she explores the effects of climate change on her Arctic home.

The debate is over about whether or not climate change is real. Irrefutable evidence from around the world - including extreme weather events, record temperatures, retreating glaciers, and rising sea levels - all point to the fact climate change is happening now and at rates much faster than previously thought.
