- USGS report finds that future climate shifts have been underestimated and warns of debilitating abrupt shift in climate that would be devastating. http://www.climatescience.gov/Library/sap/sap3-4/final-report/default.htm http://climateprogress.org/2008/11/24/what-are-the-near-term-climate-pearl-harbors/ Tipping elements in the Earth's climate - National Academies of Science “ Society may be lulled into a false sense of security by smooth projections of global change. Our synthesis of present knowledge suggests that a variety of tipping elements could reach their critical point within this century under anthropogenic climate change. “ http://www.pnas.org/content/105/6/1786.abstract?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&fulltext=tipping+elements+lenton&searchid=1&FIRSTINDEX=0&resourcetype=HWCIT Arctic Climate Change may be at tipping point – Globe and Mail -Sept 2009 We thought by 2050, multi-year [sea] ice would be cut in half,” said Mr. Stewart from Ottawa. “Well, it happened in 2007.” http://www.theglobeandmail.com/news/technology/science/arctic-climate-change-at-tipping-point/article1272939/ http://www.panda.org/wwf_news/news/?uNewsID=173262

- Building a zero carbon ICT infrastructure Purchasing green power locally is expensive with significant transmission line losses Demand for green power within cities expected to grow dramatically ICT facilities DON’T NEED TO BE LOCATED IN CITIES -Cooling also a major problem in cities But most renewable energy sites are very remote and impractical to connect to electrical grid. Can be easily reached by an optical network Provide independence from electrical utility and high costs in wheeling power Savings in transmission line losses (up to 15%) alone, plus carbon offsets can pay for moving ICT facilities to renewable energy site ICT is only industry ideally suited to relocate to renewable energy sites Also ideal for business continuity in event of climate catastrophe
