Climate Change – Security & Trust • Pentagon Considers Climate Change a National Security Threat • In its recently released Quadrennial Defense Review (QDR), the Do. D states, "Climate change and energy are two key issues that will play a significant role in shaping the future security environment. ” • http: //www. defense. gov/QDR/ 2
Global Average Temperature
2009 second warmest year ever
Spring 2010 warmest ever This is despite a solar sun spot minimum
Climate Forecasts > MIT report predicts median temperature forecast of 5. 2 °C – – 11°C increase in Northern Canada & Europe http: //globalchange. mit. edu/pubs /abstract. php? publication_id=99 0 > Last Ice age average global temperature was 5 -6 cooler °C than today – – Most of Canada & Europe was under 2 -3 km ice With BAU we are talking about 5 -6°C change in temperature in the opposite direction in less than 80 Years MIT
Urgency of Action • “We’re uncertain about the magnitude of climate change, which is inevitable, because we’re talking about reaching levels of carbon dioxide in the atmosphere not seen in millions of years. • You might think that this uncertainty weakens the case for action, but it actually strengthens it. • This risk of catastrophe, rather than the details of cost-benefit calculations, makes the most powerful case for strong climate policy. Nobel Laureate Paul • Krugman http: //www. nytimes. com/201 0/04/11/magazine/11 Econom y-t. html? pagewanted=1 Current projections of global warming in the absence of action are just too close to the kinds of numbers associated with doomsday scenarios. It would be irresponsible — it’s tempting to say criminally irresponsible — not to step back from what could all too easily turn out to be the edge of a cliff. ”
The Falsehood of Energy Efficiency • Most current approaches to reduce carbon footprint are focused on increased energy efficiency of equipment and processes • Also greater efficiency can paradoxically increase energy consumption by reducing overall cost service and therefore stimulates demand – Khazzoom-Brookes postulate (aka Jevons paradox - not to be confused with rebound effect) – In last Energy crisis in 1973 Congress passed first energy efficiency laws (CAFÉ) which mandate minimum mileage for cars, home insulation and appliances – Net effect was to reduce cost of driving car, heating or cooling home, and electricity required for appliances – Consumer response was to drive further, buy bigger homes and appliances • The issue is not the amount of energy that we use, but the type of energy

Building a R&E “ 5 G” wireless sensor network • Enabling Innovation with next generation wireless 5 G Internet + clouds - technical details http: //bit. ly/c 3 i. Zs. Z 3: 18 PM Apr 25 th • National R&E wireless network for students and researchers • Existing 3 G and 4 G networks cannot handle sensor data load • Need to offload data at nearest node or tower at university campus • New Wifi standards 802. 11 u allow for data handoff from 3 G networks • Wi. Fi nodes can be powered by renewable sources such as roof top solar panel over 400 Hz power systems or ethernet power • Most applications will run in the cloud
Impact of 5 G sensor networks • The PC is out of the loop • The phone and i. Pad is a sensor platform • Processing is done in real time in the cloud – Allowing processing that can’t be done on the device – Big data analysis • Building new virtual networks on the back of existing commercial 3 G networks • Reinventing a major industry • More on revenue opportunities for R&E and open access networks - building next generation "5 G" wireless network http: //bit. ly/dck 1 k.

SIM cards & PST • SIM cards likely to be main vehicle for consumer identity and authentication with proliferation of smart phones • Next gen SIM Cards integrate with new functionality… – Address book, calendar back-up, messaging, teleconferencing and file transfers, banking and access control, Web! • Smart Card Web Server - Web apps right on SIM Cards! And TCP stacks • Cell phone companies will be soon competing with Visa and Master. Card for Point of Sales • Security, identity and authentication – will be under control of cell phone company • Need open standards and controls for SIM cards 14
