    Tracking Deforestation in Real Time

    Google.org, Google’s philanthropic arm, has announced a cloud-based method for analyzing deforestation around the world, in a much more up-to-date manner than previously possible.

    Using Google’s terabytes of satellite imagery, it allows scientists to look back over time at any location in the world and see how the forest has changed. Going beyond visual comparisons, it uses the power of cloud computing to do actual measurement of deforestation. Much more rapid analysis of the images than is possible on a single desktop computer pinpoints locations of most recent activity. This allows authorities to location illegal logging very precisely, within days of the activity.

    With this technology, it’s now possible for scientists to analyze raw satellite imagery data and extract meaningful information about the world’s forests, such as locations and measurements of deforestation or even regeneration of a forest. In developing this prototype, we’ve collaborated with Greg Asner of Carnegie Institution for Science, and Carlos Souza of Imazon. Greg and Carlos are both at the cutting edge of forest science and have developed software that creates forest cover and deforestation maps from satellite imagery. Organizations across Latin America use Greg’s program, Carnegie Landsat Analysis System (CLASlite), and Carlos’ program, Sistema de Alerta de Deforestation (SAD), to analyze forest cover change. However, widespread use of this analysis has been hampered by lack of access to satellite imagery data and computational resources for processing.

    Why Aren't Insurers More Active on Global Warming?

    A report out today from Munich Re Group (an insurer of insurance companies) says that 2008 is the third highest on record in terms of financial losses caused by natural disasters (not to mention 220,000 human lives), and puts much of the blame on global warming.

    Bloomberg reports (emphases mine):

    Worldwide insured losses related to natural catastrophes increased about 50 percent to an estimated $45 billion last year compared with 2007, the world’s biggest reinsurer said in an e- mailed statement today. Overall losses more than doubled to about $200 billion, the Munich-based company said.

    Natural disasters cost more than 220,000 lives even as the total number of such events declined 22 percent to 750, the report showed. China’s earthquake in Sichuan province in May claimed about 70,000 lives and cost $85 billion in overall losses, while Tropical Cyclone Nargis killed about 84,500 in Myanmar. September’s Hurricane Ike in the U.S. was the most expensive natural disaster for insurers, costing $15 billion.

    “Climate change has already started and is very probably contributing to increasingly frequent weather extremes and ensuing natural catastrophes,” management board member Torsten Jeworrek said. “2008 has again shown how important it is for us to analyze risks like climate change in all their facets and to manage the business accordingly.”

    Munich Re has been quite vocal in arguing that global warming and climate volatility are leading the insurance industry toward a financial cataclysm. According to this article, Munich Re has taken a longer view of future climate scenarios and their financial impacts, which is only prudent. While US insurers were more active on this a couple of years ago, they seem to have fallen off in their efforts, despite a more open attitude from consumers to look at green alternatives and incentives.

    As one commentator put it,

    “European insurers, and particularly Munich Re and Swiss Re, have always thought longer term,” said Christopher Treanor, chief executive of insurance broker Mercator Risk Services. “The U.S. as a business culture takes a shorter view.”

    Where have we heard this before? This short-term thinking is getting to be a fucking epidemic, and look where it’s got us. It has to stop or we’re just going to hell in a handbasket.

    Allstate, State Farm, Firemans, Progressive, Hartford - I’m calling you out. Get off your butts and start doing something about this. Why aren’t I seeing commercials from you extolling the virtues of gas-saving cars and taking public transit? Why aren’t you making it very expensive to air-freight products from China? Why don’t you give me a big break if I do a great job insulating my house?

    Heck even the health insurers could get in on the act. If I eat more vegetables and less meat, and eat locally grown seasonal produce, I’m doing the earth a favor as well as my body. Reward me for it and help head off financial ruin at the same time.

    And yes I realize this means you competitors have to do this collectively, or individually you’ll shoot yourselves in the foot with higher rates. But divided you will fall, and united you might just squeak by. If the current global economic meltdown has shown us anything, we’re all in this together. Acting selfishly gets us nowhere.

    Gas Prices Catch up with Detroit

    The always provocative Jamie Kitman, columnist for Automobile magazine amongst others, has a piece in the September issue calling out the Big Three automakers (or The Moderately Large Three, he demurs) for their decades long lack of responsiveness on the issue of fuel economy.

    Game over. After almost half a century of fighting battles, America’s Big Three have at long last lost the war. Yes, it’s official. From this day forward, fuel economy matters… Too bad Detroit carmakers weren’t prepared. They only had fifty years to get ready.
    Detroit didn’t have to encourage profligacy, it chose to. And some will argue that the power of advertising dollars could and should have been used to encourage efficiency. The American industry could have planned the same patriotic card it deployed following 9/11 to advocate fuel conservation instead of throwing around billions of dollars to make sure there were large SUVs in every garage. It didn’t have to spend some four decades fighting safety, emissions, and fuel-efficiency standards.
    Clearly this is not just a down year, it’s a total paradigm shift… Cars that seemed like pretty good ideas suddenly seem less inspired. Cars that appeared bad ideas before now seem like the worst ideas ever. The Hummer brand, for instance, is on target to sell fewer than 35,000 units this year, or about twelve percent the number of Oldsmobiles GM was selling when it decided to shut that venerable brand to concentrate on…Hummer.

    Strangely enough, while typing this up I’m listening to a Tivo’d recording of Charlie Rose’s interview with GM CEO Rick Wagoner. It’s a good interview, but obviously he gives quite a different perspective than Kitman (who points out that Wagoner got a 64% raise to $15.7M in 2007, despite GM’s heavy losses). And I can’t say that I can entirely blame the automakers for the large trucks. People bought them, and they didn’t buy small cars, for the most part, so the financial imperative in the near term was fairly clear.

    But one thing Wagoner just said jumped out at me: he thinks the US government should get behind funding the startup costs for new energy sources, such as fuel cells and batteries, in order to kick-start the growth and innovation. But 15 minutes before he was bemoaning the role of governments outside the US supporting their domestic auto industries because it makes it unfair for competitors (i.e. GM) to compete. Seems to me that you can’t have it both ways though - either government intervention in helping domestic manufacturers get rolling in a new industry is OK, or it isn’t.

    Fixing Global Warming is an Information Design Problem

    algore.jpg 

    As I was listening to Al Gore on Fresh Air yesterday (5/30) talk about his new book and movie, “An Inconvenient Truth”, it occurred to me that solving global warming, if that’s possible still, is an information design problem.

    Maybe this is pretty self evident to others, so bear with me while I noodle on what appear to me to be the three major roadblocks, and how information design can help.

    We don’t understand systems well

    Global warming is a systemic problem, no surprise there. Unfortunately our tools for understanding systems, as opposed to components of systems, are still pretty poor. Despite the best efforts of people such as Douglas Englebart, the overall capacity of humanity to comprehend and tackle complex systems has remained rather low. There are esoteric examples to the contrary, such as game theory and other economic models, but for the lay person we are still woefully under-equipped. Examples? News media give little context for events, instead treating a local shooting or Darfur as isolated “who could have known” events. Our educational systems don’t help that much, they tend to focus on discrete events but don’t tie them together very well (wars and inventions are largely taught in a vacuum). Things get even worse the further along educationally you go, as specialization increases and separation between disciplines grows ever larger, particularly in the sciences.

    Everything that we do contributes to global warming. Sitting at home watching TV causes it. This leads to a state of paralysis. I pretty much throw up my arms in despair. It seems beyond my control.

    Who’s looking at the big picture? Who is able to connect what’s going on with their species of algae with what’s going on in the ionosphere and connect that back to oil derivatives?

    Not everything in the system matters (as much)

    Has anyone done a sensitivity analysis on the causes of global warming? In other words, what things should we focus on for the biggest impact on preventing ourselves from passing the point of no return, if we haven’t already? Are the usual suspects (cars, power plants, etc.) really the biggest problems? What if unplugging all my electronic devices at night has a bigger impact than driving a Prius? (Especially since it takes more energy to make a Prius than it will consume in its lifetime.)

    Everything that we do contributes to global warming. Sitting at home watching TV causes it (TV and lighting requires electricity, and burning coal is a primary means of generating electricity in the US). This leads to a state of paralysis. If my mere existence on the planet (at least in the developed nations) is causing harm, I pretty much throw up my arms in despair. It seems beyond my control.

    However, tell me what the top 3 things are that will have a big impact, now that I can handle.

    Another tendancy is to link global warming and environmentalism with a broader political agenda: human rights, worker rights, economic inequality, organic agriculture. There is overlap in some of these to be sure, but let’s not kid ourselves: these are problems that have been around for centuries and will probably still be around for centuries. We can’t wait that long to solve global warming. These are baggage that are slowing us down. Deal with them separately. Bill McKibben puts it succinctly:

    There are, obviously, all kinds of ecological perils out there. We’ve overfished our seas, we’ve overcut our forests. Fresh water is beginning to run short, and species are disappearing at a rapid rate. You can come up with a long and troubling list, including the disturbing fact that most of the world’s people are so poor they can barely summon the energy to care about the larger world. But it’s becoming very clear that the overriding, overpowering summation of them all is climate change—lose this battle and it won’t matter if we win all the others, because it’s simply so much bigger, and connected to everything else.

    Understanding systems requires feedback loops

    A big part of successfully understanding systems is understanding the influences the components have on one-another, which means having understandable feedback loops. Simple systems can easily be understood with clear feedback loops: flick this switch and this light goes on. My dogs understand that the clanging of a metal bowl means food is coming soon (though the light switch is probably beyond them). But how long do you think it took humans to figure out that sex caused children? It’s self-evident now, but not perhaps not so obvious to old Homo Erectus, given that sex was probably fairly frequent and there’s a nine month time lag until the end-result.

    In The Design of Everyday Things Don Norman talks about the old-style controls in refrigerators for adjusting relative coolness of fridge and freezer. In the old days these were inter-dependent so it was somewhat complicated to get them right. It was easy to tell the symptoms (my ice cream has melted or my milk has frozen), but not what to do about it. The fridge made understanding the feedback loop challenging, first by a lack of intuition in the controls, and second by having a 24 hour period go by before you could tell what effect your adjustments had had. Humans just don’t do very well with that kind of time frame. Light switch, yes. Fridge, no.

    Now extrapolate that feedback loop out to periods of decades or centuries, which is what the time lag is for most climate change.

    Information Design to the Rescue?

    So to sum up: Improve our understanding of the system, find out what will have the biggest impact to change it, and then give people a tight feedback loop so they know their actions are having the desired effect.

    This has information design written (or drawn) all over it.

    seed_cyclone.jpgThere are some great examples of information design in regards to the environment, such as Seed Magazine’s annual report on the planet (graphic at left is from it). However, most just tell us the symptoms. That’s like the evening news telling me someone got shot in my neighborhood: it makes me worried, it makes me feel helpless, it makes it seem random. None of these are true, and we need to dig deeper. Providing a real understanding of the global climate and what causes what should be Job One for information designers today.

    I haven’t seen An Inconvenient Truth yet, or had the opportunity to hear Gore give his presentation, which is apparently very good, so maybe he goes beyond this level, but the website falls into the same trap. For example, there’s an eCard you can send that compares a glacier from 1978 and 2004. News I should be worried about? Yes. News I can use? Not so much. There are several pages of tips of things one can do to decrease your environmental footprint, however these lack the crucial feedback loop to tell you whether you are doing enough or give you the pat on the back from making a successful contribution. Without the feedback it’s like setting aside money for your 401k each paycheck (causing you near term pain) but never giving you a statement or prediction of your future income (to let you track progress toward a tangible future).

    Information design is also largely about “compared to what?” as Edward Tufte would say. Help us understand which parts of the system really matter by showing us this compared to that. This helps our decision making and will get us to a solution quicker.

    Lastly, use visual design (static, dynamic, whatever) to convert the feedback loop of cause/effect from abstract and distant to concrete and visceral. This lets us know we are doing the right thing and gives feedback as to progress.
