I returned from a trip to Boston this weekend to find much warmer temperatures in the nation’s capital. Although I did not venture outside the office midday, Weather.com tells me today’s high was in the mid-50s. Many around me are welcoming the shift to milder weather; I must admit I enjoyed the cold snap, and particularly the great Mid-Atlantic blizzard that blanketed the city in over a foot of snow just before the holiday “recess.” Of course, I’m not a farmer dependent on seasonable conditions to sustain crop yields–and even I missed the fresh produce that succumbed to the frost when I visited the local market last month.

Why did the entire Eastern U.S. and much of Eurasia experience such a chilly several weeks? You may or may not have heard buzz about the Arctic Oscillation, a climatic phenomenon not unlike El Niño/La Niña. The main difference: The Arctic Oscillation (AO) is a north-south shift in pressure and temperature in the atmosphere and ocean, while El Niño/La Niña is an east-west shift in pressure and temperature. Well, at a basic level.

Check out this thematic map, which compares December 2009 surface temperatures with December 2000-2008 averages around the globe.

Do you hear what I hear?

 

soundtrackr.pngA friend sent me this story about a new iPhone app that lets you geotag your own musical journeys–and discover neighbors with similar tastes in music.

Think of it as Pandora with propinquity: Just like the popular internet radio station, Soundtrackr creates playlists based on users’ favorite songs and artists. But then it goes one step further, allowing the user to tag favorite stations by where they listen. Then, by searching for similar locations and playlists, they can find out what others in their vicinity are tuning in to.

Gearing Up for Climate Change in Copenhagen

Thumbnail image for 800px-Copnhagen_Arial_View_Night.jpgThe United Nations Climate Change Conference is underway in Copenhagen. Over the course of the 12 day summit, participants from 192 countries representing governments, the business community, and civil society will attempt to agree on “an ambitious, global agreement that meets the challenge set by science,” although many officials doubt that a solid treaty will be achieved. Instead, Yvo de Boer, executive secretary of the United Nations Framework Convention on Climate Change, outlined these four questions, and feels that if these questions are answered, a sufficient framework will be in place to solidify future plans:
 
1. How much are the industrialized countries willing to reduce their emissions of greenhouse gases?
 
2. How much are major developing countries such as China and India willing to do to limit the growth of their emissions?
 
3. How is the help needed by developing countries to engage in reducing their emissions and adapting to the impacts of climate change going to be financed?
 
4. How is that money going to be managed?
 
Hammering out all the little details will be tricky, de Boer says, but if conference participants can agree on these points, he’ll be happy.

So why do we care as geographers?

This conference highlights environmental, political, and cultural issues… all topics that geographers study. The effect that this conference could have on climate legislation is clear, but just think about the logistics and cultural hurdles of getting representatives from every country in the UN together in one place to come to a solid agreement. A tricky game to play!

Sheila Keller Powell- Farmers’ Market Geography Lessons

Sheila is part of the Utah Geographic Alliance, a semi-retired teacher / “preacher”/ presenter providing resources for teachers, and is always promoting the “gospel” of geographic literacy….wherever she roams.

image_kellerpowell_1.JPGI have been following the exponential growth of farmers’ markets in our state (UT) for several years. Most of our bigger cities and smaller towns now have farmers’ markets as outlets for fresh “locally” grown, lower cost fresh vegetables/fruits, and as community gathering events. My small town, which is agriculturally-based & under pressure from rapid urbanization, has a privately run farmers’ market, but has few truly agricultural vendors (instead it has more art/crafts vendors).  I was convinced our town needed a “true” (agricultural produce and products only) farmers’ market, and so I went to our community council meeting to propose the idea of a farmers’ market in our town.  I did my homework in order to prepare for the meeting; and geography was at the top of my list.  Apparently I convinced the community council of the need for a farmers’ market, because I quickly found myself, along with a volunteer from the community council, in charge of organizing and co-managing a small farmers’ market in my town for about 7 weeks August-October of this year. WOW! What a lot of work, and geography was involved at every turn in the organization process:

Impressions of Berlin

Thumbnail image for Thumbnail image for tor.JPGYesterday marked the 20th anniversary of the fall of the Berlin Wall. The New York Times has featured articles, user-submitted photos, interactive timelines, and multimedia graphics all week to celebrate the November 9th, 1989 event. I certainly don’t recall the day (two-year-olds generally don’t have a knack for remembering these kinds of things), but I can definitely imagine the throngs of people pouring through the Brandenburg Gate on that evening 20 years ago. I was lucky enough to be in Berlin for New Years Eve last winter, where over a million people flooded the streets around the Gate to ring in 2009. The excitement in the air was palpable that night, and I can only imagine an even greater electricity on the night the wall came down.

The Berlin Wall was an enormously significant historical and geographical marker, the effects of which visitors to the city can still see and feel. During my visit, I blogged about my first impressions of the city. Although I wrote it 11 months ago, I think the entry sums up the city and the legacy of the wall well–very appropriate for this occasion! Enjoy!
