Peter H. Gleick: Desalination: Let the Buyer Beware By Heather Cooley and Peter Gleick In a new report issued today, the Pacific Institute released the results of a year-long analysis of the complex and controversial costs of seawater desalination. The conclusion? It is still really expensive, especially compared to alternatives. The Institute has long addressed the scientific, environmental, and financial issues associated with seawater desalination -- a technology often seen as having the potential to contribute to local and regional water supplies and reduce pressures on existing water resources as well as ameliorate the threat of droughts.
Arctic Sea Ice News & Analysis The sea ice extent has been quickly growing, and by the end of October, ice covered most of the Arctic Ocean. Overall, the ice extent remained below average for this time of year in the Barents and Kara Seas, as well as within northern Baffin Bay and the East Greenland Sea. Overview of conditions Figure 1. How farmers can help fight climate change The other week, I spent some time interviewing several business leaders for the North Carolina Sustainability CEnter, asking them about their reactions to President Obama's climate speach. Their responses were decidedly mixed, but one discussion stayed with me. When I asked Charles Sydnor, the owner of Braeburn Farm, about the urgency of climate policy for his industry—he had this to say: "As a farmer, when we look at climate change there are two sides to the story – but we only really talk about one – namely the production of greenhouse gases. Yet agriculture should be part of the solution. I can take you to places right now where crops are grown year-after-year-after-year without tilling the land, and where there is increased carbon sequestration year-after-year.
40 Witty Campaign Posters for a Cause Non-profit organizations use posters to deliver a particular message. These help inform people about current issues, problems and even the possible consequences of their actions. With a sentence that contains strong words or images, these posters give more impact than common commercial posters. 'Debate on Science is Over, Time to Act Is Now': World Reacts to IPCC Report The new report further states that greenhouse gas emissions at or above current rates would induce changes in the oceans, ice caps, glaciers, the biosphere, and other components of the climate system. (Underlying photo: UNEP)Following the release of the IPCC's first installment of its fifth assessment report (AR5) on climate change in Stockholm on Friday, environmental groups, experts, and activists from around the world were reacting to the findings contained in the report and commenting on the implications it will or should have as the planet faces the "unprecedented" rate of global warming and the irrefutable consensus by the world's scientific community. For most, the report's findings represent only a more precise and updated affirmation of what has been known to most experts for decades. What follows is a sampling of those reactions and perspective from those on the frontline of the climate issue.
Can motors in wheels spark electric car revolution? There may have been more alluring electric cars on display at this year's Tokyo Motor Show, but the beauty of this prototype lies in its performance. The SIM-LEI can travel 333 kilometers (more than 200 miles) on a single charge, say its Japanese creators SIM Drive, and it also boasts supercar-like acceleration -- 0 to 60 mph in just 4.8 seconds. The key to these remarkable statistics lies not, as you might expect, underneath the hood but in its wheels. Most electric vehicles house a single motor in the area vacated by the petrol engine, but the SIM-LEI has four motors, which fit in the hubs its wheels. Each one delivers 65 kilowatts, giving the car a total output of 260 kilowatts, compared with the 80 kilowatts of output available in, say, the Nissan Leaf. A 24.5 kWh battery sits below the floor along with inverters and controllers, which fit into a unique steel monocoque helping reduce weight, according to SIM Drive.
Wealthy nations pledged billions to help the poor adapt to climate change. Where did it all go? One of the cruel ironies of climate change is that the poor countries that have contributed the least to the problem are expected to get hit the hardest.

Grime-fighting garments aim to purify air Polymer chemist Tony Ryan and fashion designer Helen Storey have joined forces to create clothing which can purify the air. Catalytic Clothing contains the same nanotechnology found in self-cleaning paints and glasses but applies it to clothes via a special fabric conditioner. A catalyst -- titanium dioxide -- applied during a normal home washing cycle breaks down harmful airborne pollutants when exposed to ultraviolet light.
Naomi Klein: How science is telling us all to revolt In December 2012, a pink-haired complex systems researcher named Brad Werner made his way through the throng of 24,000 earth and space scientists at the Fall Meeting of the American Geophysical Union, held annually in San Francisco. This year’s conference had some big-name participants, from Ed Stone of Nasa’s Voyager project, explaining a new milestone on the path to interstellar space, to the film-maker James Cameron, discussing his adventures in deep-sea submersibles. But it was Werner’s own session that was attracting much of the buzz. It was titled “Is Earth F**ked?” (full title: “Is Earth F**ked? Dynamical Futility of Global Environmental Management and Possibilities for Sustainability via Direct Action Activism”).
50 Ideas for the New City The Omnibus is all about ideas. From the beginning, Urban Omnibus has been a showcase of good ideas for the future of cities, conceived in the public interest and tried and tested in the five boroughs of New York. So, we have decided to surface some of the ideas that have appeared on Urban Omnibus over the past two years and broadcast them around the city.
