    Reflecting on Wellstone Week

    October 24, 2007 at 2:52 pm

    "Politics is what we create by what we do, what we hope for, and what we dare to imagine."

    -Paul Wellstone

    This week Carleton celebrates the life and work of Paul Wellstone, a former political science professor at Carleton and U.S. Senator from Minnesota. A number of campus events have been organized in his honor this week, as tomorrow will mark the five-year anniversary of his tragic death in a plane crash. At Shrinking Footprints, we thought that it would be appropriate to take this opportunity to reflect upon the late Senator's support for environmental issues. In addition to his tireless efforts to reform legislation involving campaign finance, health care, veterans, and mental health issues, Wellstone was known in the Senate as a dogged supporter environmental protection. From his involvement in a dispute about the placement of power lines in the 1970s that made him an early advocate for decentralized, renewable energy to a 2001 battle against the confirmation of former Interior Secretary Gale Norton, Wellstone was on the front lines of many congressional environmental debates.

    Fires in Southern California (from Space)

    October 24, 2007 at 10:03 am

    From NASA's Earth Observatory:

    "Driven by Santa Ana winds, several large wildfires flared across Southern California over the weekend of October 20, 2007. This pair of images of the area around Los Angeles on October 21 shows just how rapidly the fires grew. The top image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite at 11:35 a.m. local time, shows several active fires (outlined in red) emitting small plumes of smoke. By 2:50 p.m., when the Aqua satellite passed overhead, smoke was pouring from several large blazes northwest of Los Angeles. Although Aqua MODIS only caught the edge of the scene during this satellite overpass, the plumes of smoke and dust that can be seen blowing off the coast in the large image indicate the intensity of the winds and the presence of additional fires farther south."

  • Opaque Skies over China

    Trade Balances Impact Global Emissions Accounting

    October 23, 2007 at 10:29 am

    Without a doubt, emissions in China will have to be addressed if we are to solve climate change. China is currently adding two coal plants to its electricity grid every week. If this pace continues, global emissions will rise above any stabilization threshold, whether its James Hansen’s 450 ppm or the more conventional 550ppm.

    However, what few people are pointing out today is what sectors China’s emissions are coming from. A recently released Tyndall Center report found that China’s net exports account for more than 23% of GHG emissions. These emissions are roughly equal to all of the UK. While the concept of exporting emissions isn’t a new topic, this is, as far as I know, the first time a number was estimated for China.

    The Tyndall Report illustrates how the current GHG accounting process fails to fully account for western nations’ emissions and consumption. If US, UK, or Canadian products are produced in China, I don’t think we should be let off the hook for those emissions. If the US does implement legislation for reducing GHG emissions, in most scenarios, these exports will not be counted. Furthermore, if this is the case, will it not become an incentive to take more manufacturing jobs offshore? Perhaps this is good for development and growth in those countries, but shouldn’t the developing countries be allowed to increase emissions for their own economies but not for western nations’ consumption?

  • A Prairie Restoration Project

    A College on a Prairie?

    October 22, 2007 at 11:23 am

    While it is easy to justify the use of native plantings near and around the Arboretum at Carleton, some argue that prairie restoration patches closer to central campus are inappropriate and a nuisance. Depending on the season, prairie can look like dry weeds and it also requires regular burning to maintain. What should the landscape on campus look like? A well-irrigated golf course? An ornamental garden? Native prairie? The jury is still out.

    As Carleton enters into a new phase of construction with a new Arts Building and one or more dormitory projects, the College is increasingly forced think about space. Believe it or not, space is limited on our campus. As a result, the placement of every landscape feature, ranging from our large recreation center to the kale now sitting in the Sayles planters, is intentional. Given the pending expansion of the Carleton student body, it is in the college’s best interest to maintain green space as well as to make the green spaces it has more green. How does the college incorporate sustainability into its landscaping operations? While Carleton does not have a specific provision in its landscaping operational guidelines that formally incorporates sustainability, there is an intentional effort to do so.

    First and foremost, Carleton strives to use plants native to southeastern Minnesota in its design scheme. According to an unofficial landscaping document drafted in the summer of 2007, the campus is divided into a variety of zones, each with their own design parameters (vegetation choices and placement, maintenance specifications, etc). Vegetation in Zone 1 (which encompasses the Rec Center/ Goodhue building sites) is expected to consist of species native to southeastern MN. Non-native plants are to be used sparingly and only when similar native species are not available in the proper size, form, or quantity. Vegetation in Zones 2 and 3 (the Arboretum Corridor and the Arboretum itself) are even more specified. Plants in these areas are limited to vegetation common to Rice County and, in the Arb, should be arranged “randomly or in associations typically found in the area”. The fourth and last landscaping zone includes campus and off-campus properties. This zone is perhaps the most important and the most difficult to design. With respect to Zone 4, the unofficial landscaping document states, “While there are no established limitations regarding the use of non-native plant material, it is understood that responsible and sustainable landscaping practices favor the selection and predominant use of fully hardy species native and adapted to the region.”

  • Compact Fluorescent Float

    Compact Fluorescent Lights (aka CFLs)

    October 22, 2007 at 11:06 am

    The college gives away Compact Fluorescent Lights, so why not limit the amount of energy you use in your dorm room by simply installing them in your desk lamp?


    Having recognized the major energy savings of using Compact Fluorescent Lighting (CFLs) (they use about a quarter of the energy used by traditional incandescent bulbs), the college has put CFLs in most light fixtures around campus (including dorm rooms) in the last few years. Because the college cannot control the type of bulbs students use in their personal lamps, Facilities simply gives CFLs to students for free. Call Facilities at x 4133.

    And, make the switch soon. There is no need to wait until the incandescent bulb in your desk lamp burns out. Simply throw your incandescent light bulb in the trash. The sooner you make the switch, the sooner you’ll start saving energy. Currently, Facilities distributes the equivalent of 60 and 100 watt incandescent bulbs (used by most lamps) CFLs to students.

    As a CFL user, there are a few things you should know. While naturally CFL use minimizes the amount of the pollutants (including mercury) pumped out of power plants, the CFLs themselves do contain trace amounts of mercury. While not a huge safety hazard, there are certain precautions you can take in the event that a CFL breaks or if you would simply like to get rid of them once they burn out.

    Food Musings: Edible Communities

    October 19, 2007 at 10:06 am

    First one at the co-op, that stylish matte paper displaying fluted, orange-hued orbs of winter squash, “celebrating the abundance of local foods, season by season.” Then another arrived in the mail, “celebrating the abundance of North Central New Mexico, season by season.” Proclaiming stories such as “A Homegrown Wedding” and “Got Raw Milk?” these publications of edible TWIN CITIES and edible SANTA FE are two of a collection of thirty-plus magazines published regionally around the United States to promote the bounty and beauty of local foods.

    As an organization, edible Communities strives to “connect consumers with family farmers, growers, chefs, and food artisans of all kinds” and believes that “every person has the right to affordable, fresh, healthful food on a daily basis and that knowing where our food comes from is a powerful thing.” The edible Communities website details how individuals can begin an edible publication in their region, and the benefits of belonging to a larger food-impassioned organization as opposed to starting up on your own. Current publications stretch from Toronto to San Diego and from Cape Cod to Portland. Individuals can purchase multi-region subscriptions and receive publications from three different regions throughout the year.

    Both edible publications I have in from of me are remarkable in their beauty and accessibility. Now delicious, elegant food is featured not only on the glossy pages of advertisement-heavy mega-magazines with intimidating titles. The recipes and writing in edible publications feel approachable because they are familiar. A Minnesotan has perhaps visited one of the featured restaurants, shopped at several of the farmer’s markets listed and certainly has the ingredients for all of the recipes available to them, if not in their own backyard. The Santa Fe issue feels appropriately less familiar to a reader from the Midwest in features such as “A Tribute to Red Chile,” but the passion for strong communities formed around good, regional food reverberates through its pages, uniting it with the Twin Cities edition and all of the regional publications.

    Emanuel Explains Warming-Hurricane Connections, Calls on Students to Join Field

    October 18, 2007 at 9:12 pm

    Speaking at Carleton on Wednesday evening, Kerry Emanuel presented a fascinating picture of hurricanes in their relation to global warming. Emanuel, a professor of Earth, Atmospheric, and Planetary Sciences at the Massachusetts Institute of Technology, is known as a foremost expert in the small but increasingly important field concerning the impact of climate upon the number and intensity of hurricanes. In his remarks Wednesday night, Emanuel described some of the basic science behind hurricanes before delving into the research that has been done regarding trends in hurricane power (which he argued is a more important metric that hurricane number). Over the past century, ocean temperature has shown a strong correlation with hurricane power. Since increased ocean temperatures are one of the more direct impacts of global warming, this relationship could have real impacts upon coastal communities.

    Sleep Mode= Power Drain

    October 18, 2007 at 9:10 am

    The Christian-Science Monitor has a great, short article about how the "sleep mode" on our electrical appliances still uses a lot of power.

    From the article:
    "In standby, a machine is not really turned off. It goes into a state of reduced activity that requires only minimal power consumption. The downside is that even at vastly reduced power levels, millions of machines running all day, every day, adds up to huge amounts of wasted energy. With oil prices at record highs and the climate under threat from excessive consumption of fossil fuels, this is neither smart nor desirable."

    "The US Department of Energy has estimated that by 2010, the portion of each utility customer's bill consumed by appliances in standby mode will reach 20"

    Reclaiming the Future

    October 18, 2007 at 8:43 am

    “Try this experiment. Go knock on someone’s door in West Oakland, Watts or Newark and say: ‘We gotta really big problem!’ They say: ‘We do? We do?’ ‘Yeah, we gotta really big problem!’ ‘We do? We do?’ ‘Yeah, we gotta save the polar bears! You may not make it out of this neighborhood alive, but we gotta save the polar bears!’ ”

    If this key communication disconnect continues, Jones, a visionary Oakland-based activist, explains, we will never find solutions to either social inequality or environmental destruction. Instead, we need a “green economy strong enough to lift people out of poverty.” Green For All, based out of the Ella Baker Center for Human Rights in Oakland, seeks to bring “green collar” jobs to urban areas. If young people of color start installing solar panels now, explains, Jones, they’ll become managers in five years, owners in ten, and eventually inventors.

    The publicity this initiative has been enjoying the past week (New York Times and The Nation) speaks to the revolutionary nature of the program, and a revolution people have been waiting for. Van Jones believes these two movements have been separated for too long, and his passion is contagious. The fight to curb climate change has literally been a fight to maintain the environmental status quo, a conservative approach that turns off many people who do not benefit from the way things are. Van Jones’ environmental revolution provides hope for both sides of the double helix—-hope for a more inclusive, diverse environmental movement, and hope to lift people of color out of poverty.
