It’s Gettin’ Hot in Here: ‘How Many Gigatons of CO2?’ (Infographic)

Designed by David McCandless, this infographic… illustrates the amount of carbon dioxide that has been released into the atmosphere, how much can “safely” be released into the atmosphere and how much fossil fuel companies have ready to burn. It also associates the amount of global warming that will occur after different amounts of carbon release. If you read about climate change, you’ll sometimes hear these figures called the “carbon budget” or “the math of climate change.” It is an important and powerful concept to absorb and should change your thinking on how fast we must act.  (Source: Treehugger)

From Reuters:

The world’s urban areas will more than double in size by 2030, presenting an opportunity to build greener and healthier cities, a U.N. study showed on Monday. Simple planning measures such as more parks, trees or roof gardens could make cities less polluted and help protect plants and animals, especially in emerging nations led by China and India where city growth will be fastest, it said.

“Rich biodiversity can exist in cities and is extremely critical to people’s health and well-being,” wrote Thomas Elmqvist of the Stockholm Resilience Centre, scientific editor of the Cities and Biodiversity Outlook.

The world’s urban population is expected to surge from just over 3.5 billion now to 4.9 billion by 2030, according to the assessment by the U.N. Convention on Biological Diversity. At the same time, the area to be covered by cities will expand by 150 percent, it said.

“Most of this growth is expected to happen in small and medium-sized cities, not in megacities,” according to the report, issued to coincide with a U.N. meeting on biodiversity in Hyderabad, India. More green spaces in cities can filter dust and pollution and soak up heat-trapping carbon dioxide. Some studies have shown that the presence of trees can help reduce asthma and allergies for children living nearby, it said. And the study said that cities were also home to a wide range of animals and plants.

From Greater Greater Washington:

The central fact about cars, from a planner’s perspective, is that they take up space. Lots of space. And this matters because space in cities (a.k.a real estate) is scarce and therefore expensive.

Cars take up space when they’re moving and they take up space when they’re parked, and even though they can’t be simultaneously moving and parked, you have to plan for both states and plan for peak demand; so you have to set aside some multiple of the real estate actually occupied by the car at any given time.

That’s just a practical observation about the spatial geometry of cities that doesn’t bow to my ideology or yours. And it would still remain true even if cars ran on nothing but recycled newspapers and emitted nothing but rainbows and unicorn tears.

In the past, our policy response has been to just set aside more and more space for cars: More freeways, more roads, more lanes on existing roads, more parking garages and surface lots. This approach hasn’t worked, and there are two very practical reasons why:

First, you can never build enough. There’s a phenomenon called “induced demand” that is very well understood by now. A new lane or a new freeway never reduces congestion in the long run: People respond to new capacity by driving more or by living or working in previously remote places, and you’re very quickly back where you started and have to build still more. The same phenomenon applies to increases in the supply of parking. It’s a game you can’t win.

Second, when you do make more space for cars you quickly start to crowd out any other potential mode of transportation, especially walking. All those parking lots and freeways and roads spread everything else out so that the distances become too great for walking. And the more you optimize any given space for cars the more hostile that space is for pedestrians. Very quickly you get to the point where it becomes impossible—or prohibitively depressing—to get things done on foot.

And this last fact has huge quality-of-life implications for human beings—not just because driving to a distant strip mall for a gallon of milk is less pleasant than walking to a corner store, but also because for many people driving simply isn’t an option.

From The Globe & Mail:

This fall, Vancouver city workers will start planting some 3,000 trees, the first of the planned 150,000 called for in the city’s 2011 Greenest City Action Plan.

The cost for the first batch of trees – to be planted on both private and city-owned land – is $650,000 of the city’s budget of about $1-billion. The investment is geared to more than shade and eye appeal. Vancouver, like other cities around the world, is looking to its urban forest for benefits ranging from energy savings to pollution control.

While such benefits have long been acknowledged, technology is making it easier to measure them – in the process, helping to build a business case for greenery.

“It’s getting easier to quantify the environmental services provided by trees, because there are programs that we have been able to plug into that give us that information,” said Beth McEwen, manager of urban forest renewal with the City of Toronto, which in 2005 announced plans to boost its tree canopy from about 20 per cent to 40 per cent over the next 50 years.

Toronto used i-Tree – software developed by the U.S. Department of Agriculture’s Forest Service – for a 2010 report, Every Tree Counts, which mapped the city’s tree cover and calculated what role trees played in, for example, reducing air pollution. Vancouver will be testing the software this fall, but has not done a cost-benefit analysis of its tree-planting target. Still, the city considers it a solid investment.

“There are social and economic benefits – including cleaner air, habitat for wildlife, increased property values and neighbourhood pride, to name a few,” Ms. Blyth said.

Energy on the Mind: ‘Don’t Worry, Drive On’ (Video)

From The Post Carbon Institute:

In recent months we’ve seen a spate of articles, reports, and op-eds claiming that peak oil is a worry of the past thanks to so-called “new technologies” that can tap massive amounts of previously inaccessible stores of “unconventional” oil. “Don’t worry, drive on,” we’re told.

But as Post Carbon Institute Senior Fellow Richard Heinberg asks in this short video, what’s really new here? “What’s new is high oil prices and … the economy hates high oil prices.”

You can read more about the video, including its script here. As for Heinberg’s claim that the economy and high oil prices aren’t exactly best friends the UK’s Telegraph newspaper recently reported:

… a disturbing pattern has emerged where each tentative recovery in the world economy sets off an oil price jump that it turn aborts the process. A two point rise in global manufacturing indexes leads to a 30pc rise in oil prices a few months later.

“Oil has become an increasingly scarce commodity. A tight supply picture means that incremental increases in demand lead to an increase in prices, rather than ramping up production. The price of oil is in effect acting as an automatic stabilizer,” they said. If so, it is “stabilizing” the world economy in perma-slump.

Yet another big reason to speed the transition to a clean energy economy while building resilience.

Tools for Change: ‘Collective Intelligence: Cities as Global Sustainability Platform’ (Video)

From TEDx via YouTube:

Social media and collaborative technologies—layered with smart systems combining geo-location data with human experience—will make cities the driving sustainability force in a dawning planetary era. Cities will anticipate new risks with rapid urban systems innovation based upon crowdsourcing, virtual and physical communities, and transparent markets sensitive to full carbon and resource costs. Creatively leveraging collective intelligence for clean energy, low carbon mobility and sustainable food and water, the new urban grid will enable high local quality of life, lifelong learning and vibrant green economies.

The speaker, Warren Karlenzig, is a leader in the movement to build globally sustainable and resilient cities and the president of Common Current, a consultancy that advises cities, governments, and businesses. He’s got a great, insightful blog here. His most recent post recounts his trip to Japan to engage communities about rebuilding post-Fukushima.

The Washington Post’s award winning editorial cartoonist Tom Toles hits the climate-energy-money-politics nail on the head once again. It reminds me of the Upton Sinclair quote:

“It is difficult to get a man to understand something, when his salary* depends upon his not understanding it.”
